"After fully charging the Anker PowerCore 20100, I ended up running my own personal test to see just how many full charges I could get on my Samsung Galaxy S7. (1 Blinking light). The next morning (on day 6), I tried recharging the phone again while the 1 remaining light on the Anker Power bank was still blinking ....."
"Anker PowerCore 20100 – Review by a Frequent Flyer Business Traveler. Most of us would agree that we all carry or own multiple devices in this day and age and they all need frequent (1x /2x/3x times a day) recharging after continuous usage. I obviously own couple of power banks to charge my phone during my flights or at the airports. I always thought it would be great if one these days they made a power bank which could charge all my devices few times and it wasn’t so heavy. The four status LEDs are great and pretty accurate to show the status of battery charge left. Bullet Point Analysis: ------------------------------------. Great For. ------------------------------------.  Business Travelers.  Families on vacation.  Busy Moms & Dads on the go.  Considerate co-workers who want to help colleagues with their charging needs at office =).  College Students on long class schedules.  International travelers. ------------------------------------. The Pros. ------------------------------------.  Great form factor for the amount of battery power it packs.  Power capacity to charge your phone throughout the week (6-7 times).  Accurate charging status and battery level LEDs.  Automatic power off.  PowerIQ feature to automatically route power to the device plugged in.  Excellent value for cost. ------------------------------------. The Cons. ------------------------------------.  None I can think of for what it promises.  May be charge my laptop too =). ------------------------------------. The Specs. ------------------------------------.  Dimensions: 6.5 X 2.5 X 1.  Output: 2 USB/ 4.8A total.  Input: 5V / 2A.  About 1” bigger than Samsung S6 and 1.5” bigger than iPhone6.  Substantially lighter than any other power bank with same capacity in the market.  Capacity is as promised.  You can use your existing cell phone charger to charge the device. ------------------------------------. Summary. ------------------------------------. I think it’s established that in today’s digital and multi device environment our devices are power-hungry at all times. Phones and tablets are more advanced but they need battery juice and manufacturers have conveniently taken spare battery option out of the devices e.g. Samsung. This Anker Power Bank makes perfect sense to carry for all your smart phone and tablet charging needs."
"EDIT 04/2016: Anker reached out to me in private over a month ago, shipped me a new PowerCore free of charge and I confirmed that it was properly putting out over 1A. In addition to this, they replaced an older model PowerCore that had stopped working and I assumed was out of warranty, so I had taken it apart to diagnose what was wrong with it (bad capacitor)."

"I travel quite a bit and haven't printed a boarding pass in quite a while... As the practice of e-boarding passes continues to increase, so will the instances of anxiety due to a low battery while waiting in the security line or at the gate! I recently purchased and reviewed the Lumsing Ultrathin Portable 3-Port USB Charger 10000mAh... This thing was great except is made a high pitch noise when it charged another device. Cons: I actually prefer the taller/thinner form of the Lumsing which keeps the device ports easily accessible when in the inside pockets of my sports coat."
"So far, I've been able to charge my phone about 4 times from near empty to full before having to charge the power bank. The power bank itself requires at least 2 hours to charge from empty to full but once charged, your phone will charge to full in less time."
"On the left is the older 10,000mAh charger, right is the newer 20,000mAh charger, this charger in the middle. All things said, the charger worked amazingly well, much faster than the previous iteration of the 10,000mAh charger and much better than I expected. I have had an issue with an older charger with a built in cable, and while the charger was no longer available for sale Anker sent me a voucher for the full value of my charger, which I was able to use to purchase the older 10,000mAh charger you see in the photos."
"In less than six months three of us have replaced our broken micro usb cables. The Anker cables that come with the Anker power bank are run-of-the-mill at best. My point...if you're comfortable with having to replace the cable at some point (it's likely) than this is an awesome power bank."

Anker PowerCore+ mini, 3350mAh Lipstick-Sized Portable Charger (3rd Generation, Premium Aluminum Power Bank), One of the Most Compact External Batteries
Reviews
"Not All Batteries Are Created Equal. ***NOTE***. This review contains technical observations which I have reported to Anker. The battery I opened was verified to contain a high quality Panasonic-Sanyo NCR18650BF Lithium Ion cell, which is one of the finest cells available on the market today. - 9.99USD at Time of Review for PowerCore+ Mini in Black. Nay: - Inconsistent Fulfillment, Frequent Product Updates/Changes May Result in Order Errors and Old Product. - Inconsistent Performance of Internal DC Boost Converter Between Batteries, Affects Output Current and Capacity, Actual Available Capacity Varies Between 8.5Wh and 9.5Wh. - Possible Inconsistent Quality Control - Based on my numbers Anker deemed 2 out of 4 batteries to be possibly defective and shipped replacements (not arrived at time of this writing). In order to minimize power loss in the USB cable during whole product testing I custom-built an extra-short USB cable using 22AWG conductors, meaning that all of my numbers will be best-case scenarios for each of the batteries I tested. This was the case for me when I ordered two PowerCore+ Mini's in Black last week, and two Astro Mini's in Black showed up, although they were so close to the PowerCore+ in appearance (in fact, they are identical in appearance) that I didn't even notice the error until a couple of days later when during testing I noticed that the tail cap of the battery had "Astro Mini" written on it. At time of this writing both the Astro Mini and the PowerCore+ Mini are listed as separate products on Anker's website, and share the same capacity ratings, but have some minor published differences. During testing of the Astro Mini's I observed some troubling discrepancies that prompted me to order additional batteries. Anker's packaging has always been efficient, easy-to open, and well-thought, and these batteries were no exception. Each battery came with a short Anker USB Micro cable, a tasteful carrying case, and a short and sweet support pamphlet that tells you how to get questions answered or stuff fixed. Each battery's USB port is also covered with a sticker to remind you that the battery automatically cuts power to the port to conserve energy when not in use, and that a quick tap of the small button in the corner is all you need to get the juice flowing. Well, just do a quick search for "Lithium Ion Fire" on YouTube sometime and you'll see quickly why the FAA restricts how much lithium you can carry on an aircraft in the form of batteries, and why most major couriers won't allow you to ship Lithium batteries via Air Mail unless you have a hazmat contract with them. Serial numbers on devices this cheap are the hallmark of a manufacturer that cares because while you are unlikely to file a police report for a stolen ten dollar battery, Anker certainly wants to know which manufacturing batches are having problems, if any. ***WARNING***. I don't pull punches with batteries or battery vendors, and I didn't intend to judge this battery by its casing alone. Eventually I was able to saw off the rest of the casing without putting a scratch on the battery cell itself, and was able to reveal a Panasonic-Sanyo NCR18650BF cell soldered to a small DC boost converter PCB and USB ports. The NCR18650BF cell is a beauty of a battery cell, and represents one of the highest capacity and quality cells available on the market today. Every battery cell has two capacities. What this means is that "12.06Wh" capacity that you see on the product is only true for a couple of weeks right after Panasonic made the battery cells. By the time those cells are stored, sold to Anker, then stored again, used in manufacturing, stored again, shipped to Amazon, stored again, and then eventually shipped to you, these cells have a usable capacity of around 11.52Wh to 11.70Wh, which is actually what is reflected in the official datasheet for the NCR18650BF. I ran the NCR18650BF cell just by itself against a load of .2C or .67A and a cut-off voltage of 2.50V, the same test that Panasonic uses to get their original rating, and got a capacity of 11.4834Wh, which is just slightly under the "Minimum" rating for the cell, but it's close enough that I can't fault Anker for it. This is the real-world, best-case, available capacity of the cell before it goes through any other losses, such as those introduced by the DC/DC conversion up to 5V, before the voltage drop in your USB cable, and before the conversion losses in your device as it charges the internal battery. The harder you run the battery, the lower the available capacity of the cell is. To determine how hard the USB circuit runs the battery and look for efficiency losses, I removed the battery and connected the circuit to the monitored output on the lab power supply. Using the electronic load I applied a 5V 1A load to the USB port and monitored current draw from the power supply: USB Load Battery Load DC Boost Efficiency. 5.000V @ 1A = 5.00W 1.349A @ 4.2V = 5.67W 88.2%. 4.991V @ 1A = 4.99W 1.637A @ 3.6V = 5.89W 84.7%. 4.988V @ 1A = 4.99W 1.825A @ 3.2V = 6.06W 82.3%. Anker claims 90% efficiency with their DC converters, but since they do not publish their testing process or procedure it is impossible to know under what ideal conditions they performed their tests. Based on conversations with Anker, they are constantly updating and making changes to their designs, which is great, but because these changes aren't publicly tracked and because the batteries are sealed, there is no simple way to know what the characteristics of your battery are. It bears noting that so far all of the tests that we have discussed were performed on a battery that was labeled as "Astro Mini" and it is possible that my battery was manufactured during the early stages of the production shift. That capacity will be lower when drained faster and as you can see above, in order to charge your device at 5V @ 1A, the drain on the battery cell is more than twice that. Since modern lithium cells have a stated nominal voltage of 3.6V, I used the current draw of 1.637A and cut-off voltage of 2.50V to re-assess the capacity of the bare NCR18650BF cell to determine the actual available capacity at the higher drain rate. At the end of the day, what really matters is how the customer will use the battery, so let's get to... [Real-World Capacity and Performance]. These tests were all performed with the batteries fully sealed, assembled, and as they came directly from Amazon. In total, I tested four batteries, two of which were marked as "Astro Mini", and two of which were marked "PowerCore+ Mini", all of which were marked 3350mAh/12.06Wh. They were all designated Units A through D. For the testing procedure, I charged each battery through the USB Micro port per the instructions from Anker until they were full. I then connected each battery to the electronic load and programmed the load for a constant current draw of 1.000A, and measured the output voltage ten times per second until the battery died. Item Received Item Model Available Capacity. Astro Mini (Black) (Unit A) A1105 8.769Wh. Astro Mini (Black) (Unit B) A1105 9.345Wh. PowerCore+ Mini (Silver) (Unit C) A1104 8.607Wh. PowerCore+ Mini (Black) (Unit D) A1104 9.578Wh. The difference in capacity between the best-performing battery and the worst-performing battery was over 11%!!! My notes regarding each unit tested are as follows: Astro Mini (Black) (Unit A): Discharge remained flat and stable until the battery was approximately 75% depleted, at which point the voltage became unstable and dropped significantly. Based on the erratic behavior of the drop I believe the boost circuit began to overheat as it tried to cope with the lower input voltage of the battery cell. Based on conversations with Anker this is likely due to Anker's "Voltage Boost" feature which provides a slightly higher output voltage in order to compensate for the loss in the USB cable. While this does provide a slightly faster charge, it also results in a slightly lower available battery capacity, although this small discrepancy alone does not account for the near 1Wh difference between Units C and D. PowerCore+ Mini (Black) (Unit D): Out of all four batteries, Unit D exhibited the best performance. The output was not only super-flat through the discharge cycle, the available capacity tipped the scales at 9.578Wh @ 1A draw, which was better than any other of the batteries that I tested. I would also like to make clear that charge rate and battery capacity are completely independent of each other. I ordered four of the same battery, and ended up with four batteries that performed completely differently, which brings me to... [Anker's Response]. On 11/23/2015 I forwarded my results to Anker Support along with relevant purchase dates, serial numbers, and other information they requested. It means you're potentially throwing away vast amounts of battery capacity in your external battery pack by using an inadequate cable."
"Friends, We are gathered here today to celebrate the life of our Anker PowerCore+. I noticed my phone was near dead and so I hooked up my trusty Anker and went about my day. #sadface. Anker is survived by his older brother (also a PowerCore+), who was purchased in September and is still going strong."
"Fully charged this will bring my HTC EVO 4G LTE up from grave to full pretty close to twice. It will charge a iempire 5s grave to full twice with a bit left over."
"I was thinking of ideas to protect these from water and debris in my pocket or backpack."
"See my images). - Comes with a nice little bag that can hold the battery as well as a cable. (Note that it comes with a USB > Micro USB cable to charge the battery but you need to use your USB > X cable where X is the type of connector your phone or electronic device uses. The competitor (Jackery® Mini Premium) has 4 lights to show the amount of battery left, but on the other hand it's square so it's harder to carry in your pocket and that's the reason I got the Anker®.

"Using the same wall adapter I plug my phone into the wall and it takes about 90 minutes to charge. Why I like it: -Don't have to fumble with cord and plug (especially at night going to sleep). -Don't have to worry about angling the plug in socket to get phone to charge. -Phone's USB port not charging/working?"
"All three chargers work great and my wife also uses them for her Galaxy S7 which also has a Caseology case."
"If you have a Samsung S6 Edge Plus or Samsung Note 5, you will have issues with this charging pad and it will shut off (blue blinking light) after xx amount of minutes has passed. Place your phone onto the wireless charging pad and the blue light will start pulsating (again if it is blinking, that's bad) and "Daydream" mode will fire up. I had my Sprigen case on my S6 Edge Plus and the phone detected the wireless charging pad with no problems."
"Some people are just expecting this to be magical or didn't know what they were getting, some people may have a defective phone or charger. This is an excellent product, I've had other wireless chargers for other phones and this definitely is better than most."
"Soft rubber to protect phone (most have this but some did not, or had the rubber in weird pattern that didn't fully protect). 4."

Reviews
"This particular battery is purchased as my girlfriend really wanted a battery that she could carry in her purse as well as a battery that wouldn't take up too much space in her purse. It comes with a 5200 mAh power which can charge your phone about 1.5 times before it needs to be charged. This battery comes with four bright indicator lights which allow it to tell you how much power your have left on the battery."
"The battery comes with a micro-USB *and* a lifetime replacement warranty, something that I haven't seen much for portable batteries. As you approach the end of the battery's life it kind of stops you from using the tail end of the last dot of battery, probably to protect the battery itself which is good."
"I have the larger one (10000 maH) but wanted a smaller one I could keep in my purse and also to have for when my kids are on their tablets and need some charging which seems to be easier than plugging the tablet into the wall (my kids always end up pulling it out by mistake when it's attached to the wall- this solves that issue.)."
"Having bought multiple portable charging batteries for cell phones since I either give them away or send them to my family overseas, I have become familiar with how these battery packs work. I tested it with an iPhone and a Samsung phone, charging both to a 100% and automatically cutting the power feed to the phone avoiding overcharging the phones and retaining charge in the battery pack."
"It has very smooth, rounded edges and feels really good in my hand. My only real issue is, again, just like the 10000 mAh charger, it made a high pitch whirring noise for the first five minutes of owning it. Update: the whining noise came back and now persists when charging the pack."

"First, BEWARE of other units specifying high currents for their multiple ports only to find out that they can't deliver high power (current) on ALL of them at once. With these inexpensive adapters, I can use my charger both at home and abroad. My Charger worked perfectly."
"Finally I have a good multi-port charger. This time though I purchased the two bad ones from somewhere other than Amazon (sorry Amazon I didn't mean too, lesson learned). Once back to Amazon and reading reviews it was obvious that this one must be a good one. I have two Ipads as does my wife, two Iphones 6s and 6s plus, new Fire HD8, Multiple Bluetooth headphones and probably quite a few more that I am leaving out and they all charge great."
"There are many options to buy out there (several here on amazon), however due to my experience with Sunvalleytek (the company who sells Ravpower) I keep on coming back and recommending that if you find a similar product (sometimes almost the same – see ANKER @ $35.99 vs this unit @ 26.99) you can be assured that for the customer service alone provided by these guys you will end up way better off. Now to the review of the actual product: I've been in the market for a good USB charger for the past few years. Between the mix of android, iOS, and other devices (kindle, raspberry pi, etc) that I have, I was puzzled that no one had created a reasonable product that would charge all of them. Now, yes, I know there are several devices that have labelled ports (2.1 Amps, iOS, Android, etc), or dedicated chargers, but it's all such a hassle. For the vast majority of use cases, (i.e. those involving a mix of high and low power draw devices like phones and tablets), this should meet and exceed all requirements. Note though, that at only 40W, it can only provide high speed charging to four iPads simultaneously (or other similar big 2A draw devices)."

"INSIDE THE BOX. Inside the box you'll find…. • 1 x Nulaxy wireless bluetooth FM transmitter. • 1 x User guide. • And 1 x 3.5mm cable. CLOSER LOOK AT THE PRODUCT. The Nulaxy wireless transmitter is made out of plastic, so it's light weight. The channel plus and minus buttons allow you to set the the FM frequency of the device and the Next and previous buttons allow you to skip forward or go back to a previous track. SETTING UP AND CONNECTING. Setting up the Nulaxy Wireless Bluetooth transmitter with my cell phone was pretty simple. On your portable device, navigate to your bluetooth settings, find the KM18 source in your list of devices and connect. The only other thing left to do is set the Nulaxy to a free open FM channel and then change your FM radio to that channel as well. So if your car stereo has a 3.5mm auxiliary port, you can simply plug one end into the Nulaxy and the other end into your car stereo port. THE PRO'S. ○ One of the things I think is REALLY useful is the Once paired, always paired Bluetooth connectivity. So if it's paired with your phone and you receive a phone call while listening to music, that phone number will pop up on the Nulaxy screen. ○ Being able to take hands-free phone calls in the cabin of your vehicle is one of those Luxury conveniences offered as a feature in this unit. For those of you wanting wireless streaming capabilities and hands free phone calls in your vehicle, this is the device that will do it."
"Held down the large volume button on this device for a couple seconds and it popped up on my phone and connected. Turn volume on phone all the way up, turn the Nulaxy volume to 23 to 25, and for my radio I do about 30 to 35 for volume depending on the song. I am using Google Play Music and the next button does work to skip tracks and the large volume button does play/pause when depressed. Definitely keep phone volume all the way up, Nulaxy volume around 23 to 25 never all the way up, and you can fine tune to your system using the stereo volume with the Nulaxy volume and your bass and treble."

Reviews
"All the buttons and cutouts match perfectly and it the tempered glass screen protector he has on the IPod does not affect the way the case fits or how it functions with two screen protectors on it. I appreciate you taking the time to read my review and please select the appropriate button if you found this review helpful or not and leave any comments which may help me write a better review for consumers such as yourself."
"Also, The screen protector is curved up and away from the iPod screen so you have to give an extra hard press to get the screen to react, especially at the center of the iPod."
"This was my second time getting this IPod case as my original from 4 years ago was getting too loose and I needed another one."
"I'd owned a similar case for my old iPhone 5, which is one reason I looked to this one for my son's iPod."
"It fits the new iPod well and so far is giving me the security of safety against dropping the device."
";) This case keeps the iPod protected even in the event of an accidental fall to the ground; concrete, hardwood floors, tile- (We've personally tested this many times) It protects it if it gets thrown in a bag with a bunch of books. The only downside of this case is that it limits the kind of cord you can use as far as aftermarket due to the opening in the bottom."
"I have had it on my phone since I bought it a few months ago."
"It’s almost as if the iPod and case has to much of a gap or the protector screen is to thick to recognize the touch features."

Reviews
"A simple way of defining certified is that if a non-Apple seller wants their product to work with a newer generation iPhone, iPad or certain other devices that they pay a fee to Apple to get a compatibility code that they can use to register their adapter. Anker has jumped into the fray and has joined that small band of accessory sellers to offer a cable that is truly compatible with Apple Lightning devices. So far I have only tested 3 Lightning cables sourced from reputable companies ... Apple itself, Amazon Basics and now Anker. The Amazon caps are massive in comparison, certain to create major issues when attempting to use that cable with certain cases or receptacle connectors that are recessed. Usually the length of the end cap isn't a concern but it is worth noting here that again at the Lightning side Amazon's is much. larger than the other two brands and does not have a strain relief which could cause the cable to break at that point. Unless you have a situation where the Anker won't physically fit your case there is no other reason not to consider it an exact replacement for the Apple-branded cable ... at about half the price."
"I have bought cheap lightning cables in the past and they always showed a window that said "This cable or accessory is not certified and may not work reliably with this iphone/ ipod/ ipad" or sometimes the idevice wouldn't even recognize it, so I decided to buy Anker's lightning cable because it was affordable and MFi certified and I was very pleased with the product."
"All charging cables fail eventually, after a hard life being bunched up in purses and book bags, or on the floorboards of a truck."
"Stop working in 2 months and that's why they have only 30days returns policy. I like their service... after read my review they contacted me by email in 24 hours and mailed new cord which is working great."
"Update: Awesome customer service, after contact initiated by Anker they replaced the cable immediately when they heard of my issues."
"My original iPad, the cord I got with it still to this day works and it's been probably at minimum four years I've had it. Even the original Apple cords just stopped working one day."
"You cannot beat the price if you want to buy (as one should) only quality products."
"I'll reach out to file a warranty claim but meanwhile I'm left without a charger for the holiday weekend and my phones about to die. Edit 1/14/2018: Anker customer service shipped me a replacement at no charge--they said the original was defective."

"), because if you put the screen protector on and you trap even one lint between it and the screen, you will see it there and you might not know it's there until after you put it on. I also have an iPad but for that I had a separate screen protector installed in-store, since the surface is so much larger that the probability of even one lint landing in the way is higher. 4: Scotch tape (optional): You may (rather, WILL) find after even super-careful application that a tiny spec of lint may still appear along an edge underneath the screen protector. Other than the potential for lint to get trapped, the actual application is not so bad - feel free to readjust the angle of the protector (but try to get it right the first time); also you may massage the screen protector if it does not lay flat after you apply it. You can (gently) lift the screen protector, with a fingernail, starting from the corner, until you get just enough space to slide a strip of Scotch tape (sticky side facing the adhesive of the screen protector) to where you saw the lint. With one hand, place the tape there, and with the other, bring the screen protector back to about halfway... then pull the tape out of the side of the screen protector, and the lint might just come along with it and will not ruin it. Note: If you lift the screen protector, then keep in mind that you run the risk of trapping more/new lint, so again, find a lint-free environment and excellent lighting conditions. The feel of the screen protector is very nice."
"All I had to do was clean the screen, which was super easy because they provide everything you need, align the edges peel and stick. The cool thing about the installation is they give you guide stickers that create a hinge."
"Very pleased with this screen guard. It was very easy to apply correctly the first time."
"Judging by the use and wear I've put my Ipod through the past few days, a wipe with a nice soft cloth removes all traces of smudges, smears and spots."
"Glass protectors like this is the only way to go. Plastic protectors do not give you that smooth glass feel."
"When I put the first one on I saw a piece of fuzz of some sort that managed to get on the screen as I laid it on the ipod, even after I smoothed all the bubbles out (which were hardly any it went on so easily) I got my fingernail under an edge of the protector, took the protector off, wiped off the fuzz and pushed the protector back on with no issues."
"The iPod has been dropped several times and so far, no cracks in the screen protector."
"Honestly, it takes longer to open the super secure packaging than it does to install this screen protector."

Reviews
"Perfect for runners."
"The sweat (or likely the salt in it) eroded the case of the iPod until the battery finally stopped working. Luckily Apple was will to cover it under the warranty but now I have to take the iPod out after every run to wipe it off and let it dry. Once again the sweat was able to creep into the headphone jack and it stopped playing music on the left side. After I replaced my last iPod I started taking it out of the armband after each run and wiping it dry and letting it air out."
"Excellent for joggers.Wish band went on out side of ipod holder and not through the backside of silicone holder as well."
"This one is easy to put to use, in fact, because it is elastic, I can leave it Velcroed and hooked to slip it over my arm then all I have to do is adjust it."
"It doesn't cover the screen at all, so there's a chance of spilling something on it, but it's made very clear in the description so if you don't know that, it's because you weren't paying attention."
"Simple is better."
"I have gone through several arm bands from different manufacturers, this one is by far my favorite."
"It can also be adjusted to fit people with large biceps, and what makes it better is that the case itself can be removed and used as your everyday case for your 7th Gen Nano!"
