This solar charger can charge Androids and Apple cellphones and power station?
BigBlue 28w solar panel charger can charge most Androids and Apple cellphones, but our solar phone charger doesn't include the lightning cable for iPhone or iPad. This product comes with 2 5V USB-A output, so it can't charge power station.
Why the real output is different from the power claimed?
This product has 4 piece panel, each is 7w, so the power is 4*7w=28W; Theoretical output is 5V/2.4A Max for each port, 5V/4.0A Max in total, the total theoretical power is 5V*4.A=20W Max. But there are loss in the solar energy conversion process.
