Lantern
Tough Light 200 hrs usb
rechargeable 6000 mAh Li-ion battery
2C) Lanterns66000 mAh50.8424
6000 mAhr battery can send out 5V at 1 Amp, also lantern charges via USB with 5V input at rate of about 1 Amp, but it's actually .8 Amps per study. 6000mAhr battery takes 5V*.8Amp*6 hours to charge (max 7.5 hrs to charge?). Thus system takes P=IV, .8Amp*5V=4Watts per lantern for charging
