8Watt Solar USB Charger FAQ

a, How fast does it charge?

Firstly we have to point out that this kind of solar USB charger is without battery inside to store power, and it needs to convert sunlight to power. So a solar USB charger can not provide stable power and we need to set the fastest charging condition as sunlight is strong enough to let the solar USB charger give out its max current. Based on this to do the reference, the 8watt solar USB charger will take 120-180 minutes to charge an iPhone 12 from 40%-100% battery.

b, The solar USB charger is declared as 8watt. But when real use, why it seems to never match 8watt?

The reason is same as above. The power source for the solar USB charger is from unstable sunlight. Because it is unstable, we can only say the solar USB charger is maximum 8watt. And the max power is based on the standard test condition as STC Irradiance 1000W/m², TC=25℃, AM=1.5. Also it is related to the calculation. For example, when charging your phone, you may find the output power is 1A and 5V, then 1A x 5V = 5W. Some customers may think its max power is 5watt as per the calculating. But 8watt is for the max power of the solar panel, not the working current into the charged loads. This GGXingEnergy® 8watt solar USB charger is with max 8watt solar panel. The solar panel itself is 6V, then max output current from the solar panel is 1.2A. Thus if charging phone, the phone itself will only accept max 1A. And the voltage is stable at 5V via the USB controller to provide the safe charging condition for phone. When real use, you will get 0A-1A, decided by sunshine intension.
