I again contacted Anker support and asked for a list of batteries that have been tested with and charge properly from the Anker solar charger. The Anker Astro E7 26800mah Power Bank works perfectly with the Anker solar charger. However if the sunlight drops too low and the charger produces close to 0 ma, but then the sun comes out before the solar charger powers off, the RavPower would not charge anymore."
"My first test of the panels was on a mostly cloudy day when my power brick was charged in the 26-50% range. My pack was drained back down to the 26-50% range and was fully charged after about 4 hours in direct sunlight, using both cables. As expected the angle of the panels affected power output as well, with around 45 degrees to the current sun azimuth producing the highest output."
"Both three panel fold outs were arranged in nearly identical positions on a small table in my back yard. Both units consistently produced sufficient power to cause my 5 inch Android phone to reflect charging. I strongly suspect that both the Anker and Aukey solar chargers would have charged at a much higher rate had something more than a 5" Smart phone been used. That both the solar chargers charged the Smart phone at a greater rate than the regulated power supply would tend to validate the claim of both manufacturers that their solar chargers would charge at the fastest rate safely possible for a given device. My technical video reviews routinely require at least a couple of hours to produce and I would appreciate a helpful rating if you found it so. POSTSCRIPT. Since some of you might be interested in seeing how the Anker Solar Charger did under a greater load, I placed the panels on the same table about 1:15 p.m., again with a nearly cloudless sky; the temperature was again about 50 degrees. With the panels laying flat on the table, the Drok meter registered 4.64 volts at 1.28 amps (5.9392 watts). The Aukey charger was not tested, but since it employs the same brand, quantity and size panels, I have no reason to believe the results under a greater load would have been substantially different. POSTSCRIPT - STATING THE OBVIOUS. While there is no simple answer to realized solar panel efficiency, suffice to say that you are much more likely to achieve good results in Arizona than in New England."
Exclusive iSmart Technology: All three USB ports are equipped with iSmart technology, which automatically detects and delivers the optimal charging current for connected devices; up to 2.4A per port or 4.8A overall when used under direct sunlight.

Another is the Griffin Outdoor 10,000mAH battery bank and the smaller one is just an inexpensive 2500mAH bank.. On a sunny day in TN, this charger had no issues fully charging all the banks AT THE SAME TIME in under 5 hours. Depending on external factors, this charger might not always offer enough power to charge your high usage device.. And second, its not good for your phones to stay in the sun all day. 2.). I always recommend that a buyer only expect a charger to charge with ON AVERAGE half its capacity.."

Therefore, such folks might want to consider a lower-capacity pure-sine-wave inverter instead, such as the 150 watt Samlex PST-15S-12A or the 180 watt AIMS Power (PWRI18012S) 180W Pure Sine Power Inverter with Cables. If you want to wire this inverter for operation above 150 watts, you will need to run wire of the appropriate gauge (8 AWG, 6 AWG, 4 AWG) depending on wire length (3 feet or less, 3 to 6 feet, 6 to 10 feet, respectively). CONSIDER DC POWER SUPPLIES INSTEAD OF AN INVERTER: You might be better off obtaining DC chargers/power supplies for your devices instead of using an inverter. WHAT'S IN THE BOX: ** PST-300-12 inverter; inverter has a standard two outlet (duplex) GFCI (ground fault circuit interrupter) receptacle to connect AC loads. ** 14 AWG wire set with cigarette lighter plug to power inverter from car accessory socket. ** 12 AWG wire set with battery clamps to power inverter from battery. ** Hard copy of "Owner's Guide". ** Two set screws. SPECIFICATIONS: ** Input: 12 volts DC. ** Output: 120 volts, 60 Hz AC. ** Inverter Type: Pure sine wave. ** Continuous rating: 300 watts when wired directly to battery with larger cables; 150 watts (or less) when powered by either of the included cable sets. ** Surge rating: 500 watts. ** Peak efficiency: 88 percent. ** DC input connection type: tubular-type screw-down terminals (supplied cables have flat-blade terminals). GENERAL INFO: This is a pure-sine-wave inverter; therefore, it can power many devices that will not work with a modified-sine-wave inverter. According to the manufacturer, when either of the two provided cable sets is used to power the inverter, the load must be maintained less than 150 watts. As discussed later, to use this inverter with higher loads the inverter must be wired directly to a battery with cables of the appropriate wire gauge (8 AWG, 6 AWG, or 4 AWG, depending on cable length) and with fuse protection on the positive cable. If you want to power small loads (like an LED light) during a power outage, you could plug this inverter into a jump-starting battery pack using the included cigarette-lighter-plug cable. Therefore, switch the inverter off if the inverter is not loaded (you could also install a battery switch on the positive cable). According to the manufacturer, if you use either of these wire sets, the inverter load must be limited to less than 150 watts (or less, depending on the fuse size in your vehicle). For example, if the fuse is 10 amps, then inverter load should be limited to 80 percent of 120 watts (10 amps times 12 volts), or 96 watts DC load, or about 80 watts AC load (accounting for inverter efficiency). WIRING INVERTER FOR OPERATION UP TO 300 WATTS: If you want to run this inverter at the full load capacity of 300 watts, then you need to connect the inverter to the battery with cables larger (in diameter) than those supplied. The biggest challenge in wiring this inverter may be finding wire terminals that will work adequately with this inverter's DC inputs (which are tubular screw-down connections for flat blade crimp terminals, not screw posts for ring terminals). The manufacturer recommends the following gauges for the two wires (positive and negative) that connect the battery to the inverter: ** 3 feet or less - - - 8 AWG wires (0.1285 inch diameter). ** 3 feet to 6 feet - - - 6 AWG wires (0.1620 inch diameter). ** 6 feet to 10 feet - - - 4 AWG wires (0.2043 inch diameter). ** Greater than 10 feet - - - not addressed (therefore, not recommended). Note: A lower AWG number means a thicker (larger diameter) cable. When buying cables, make sure you meet the requirements specified by the inverter's manufacturer (wire gauge based on length of cable). FUSE IS REQUIRED ON THE POSITIVE CABLE: If you wire this inverter for 300-watt operation, you must have a fuse (or circuit breaker) on the positive wire. When wiring loads to batteries, I prefer to use marine-grade fuse blocks that connect directly to the positive battery terminal (i.e., there is no wire between the battery and the fuse block). At higher loads, a fan will start that will establish forced air flow through the inverter; therefore, you need to keep the air space around the inverter clear. LOW-VOLTAGE ALARM AND LOW-VOLTAGE SHUT DOWN: The inverter produces an alarm when input voltage drops to 10.5 VDC; the inverter will automatically shut down at an input voltage of 10.0 VDC. The inverter must be manually reset to recover from an overload shutdown: (1) the cause of the overload must be removed or otherwise corrected; (2) the inverter's power switch must be switched OFF for at least 3 minutes; (3) after the inverter has been switched OFF for at least 3 minutes, the overload should be reset and the it may be switched ON. INVERTERS AND MOTORS: If your inverter is going to run inductive loads (such as motors) then you need to consider the volt-amp requirements of your load instead of the watts, based on power factor and starting current."
"Included cable with battery clamps are for medium use, while the cable for the 12 volt lighter socket is probably good for approximately 100 watts of ac output, depending on vehicle wire and fuse size feeding the outlet. It is good to have two, as the smaller one can be portable, while a larger one should be more permanently installed."
"I use a smaller pure sine wave inverter for the TV, DishTV receiver, and laptop, but I started plugging the camper shore power cord into this inverter to run the refrigerator during the day when I have enough extra solar power; it recently ran for 3 months without having a problem, powering the refrigerator around 9 hours each day (210 watts), together with battery chargers of various sorts, a small electric heater part time at night (210 watts)."

"This morning, with a heavier overcast that threatened rain I got about 0.12 W. The output of the solar cell is very dependent on lighting conditions and your power draw. If you are powering a standard USB device (e.g. cell phone), a boost converter may be all you need; for more complicated applications you may need to add a battery and charging circuit to maintain continuous operation."
"I had a question about the number of cells and Allpowers answered my question immediately. The price is fare and the shipment time is great, I highly recommend this panel for any one wanting to add solar to their RV."
