Yes, charging your phone overnight is bad for its battery. And no, you don''t need to turn off your device to give the battery a break. Here''s why.
Supercapacitors (or electric double-layer capacitors) are high power energy storage devices that store charge at the interface between porous carbon electrodes and an electrolyte solution.
To fully charge it from cold will therefore take 7 hours. The input switch will control the amount of charge put into the bricks so setting to 1 and using 14 kWh suggests it is only actually charging for 4 hours, leaving it switched on for 4 or 7 hours will make no difference (in reality there will be a small one) to the amount of electricity ...
