Just wondering what the power draw would be for an average laptop and DSLR.
Am about to buy a battery to run a HEQ5 Pro but want to future proof myself for when I start AP.
I am led to believe the HEQ5 draws about 1.5 Ah ? Does that sound right?
I would like to get 2 full nights out of the battery before recharge.
