– 28W refers to the power of the solar panel, which is not equal to the actual output power of the USB port, because there will be some loss in order to maintain voltage stability and safety of equipment during the charging.
The power of the solar panel:
Our product has 4 solar panels, each piece is 7w; so the power is 4*7w=28W.
The actual output power means:
2 USB ports is respectively up to 5V/2.4A max and 5V/2.4A max, total output is 5V/4A Max
The total output of two output ports is 5V*4A=20W Max
– Our product is compatible with Apple device, pls use the original Apple cable.
– Any cloud cover arrives it may knock the value of ammeter down. We suggest you to replug the device and reopen the solar panels to reset the power controlle.
