I tested this charger by recharging two eneloop AA low-self-discharge batteries. I then measured the charge capacity of those eneloop cell, using the DISCHARGE function of my BT-C2000 Battery Charger Tester Analyzer. The same pair of batteries, when charged using BT-C2000 or any other Smart charger, showed an average of 1944mAh. [Batteries]. I tested the four EBL 2300mAh AA batteries, using my La Crosse BC1000 Battery Charger/Analyzer. The self-discharge rates of those EBL batteries are similar to that of ordinary NiMH batteries."
"After using these rechargeable batteries I did not see the reason to go back to batteries that you need to keep buying."

Which may not be perfect but hey I don't get paid for this: 1: The length measurement of an Amazon Basics battery (47.96mm), along side a Duracell (clearly shorter) and another brand "Heavy Duty" battery."
"its bigger but it still fits my smoke detector."
"I ordered an assortment of sizes and found they last as long as any other battery I use in these common items."
"While there are several different types to choose from, in just Amazon's AA battery models, I opted for the Performance model, and after months of use, I find they last just as long as the big two brands, and no copper-top or pink bunny will change my mind on keeping these on the top of my list."
"I like the way each battery is individually shrink wrapped because of the short problem while storing the batteries."
"On close examination, here's the only possibility I can come up with: the metal + and - terminals of the Duracell battery project slightly farther from the battery's case than the Amazon's do. These would probably work fine in any application that has an actual battery clip that snaps onto the battery terminals."
"The second photo shows some of the suds that came out the back of the washing machine."
"Today, November 22, 2016, the third smoke detector began chirping because of low battery."

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."

"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®.
