energy= 4400mWh
Charge= 1200mAh


input Solar= 5.5V / 80mA
input Solar mW = 5.5 *80 = 440mW
time to fully charge via solar
= Energy / input solar mW
= 4440 /440
~ 10 hr

not sure if I am right, but take 10hrs to fully charge in MAX sunlight...
but the battery is only 1200mAh ??

time to fully charge in usb
= 4400 / ( 5*300)
= 2.93hr
