Came within a month. And who's that professor of mythology that says ZB2L3 cannot be powered by 5Volts powerbank!! In the first picture,with 5V powerbank as source,double ZB2L3 draws 139mA max & 0.710Watts max(single should comsume less);consumed 34mAh in 16mins to test 18650 cells of capacities 249mAh & 234mAh. 1st picture was created from a youtube video tutorial, and was the final form I arrived at. Great seller, wrapped product around in foam for extra protection. I recommend store and seller!
The product is as described, the seller shipped quickly, I recommend shopping at this store because the service was 5 *****
