You mean 1000ma or 1amp? And 3000ma or 3 amp? Guessing so. I use a 2a on my v2 with the bridge, so that I can also use the IRs in the can and not worry about not having enough juice to power it.
OmgitsScience!
All using Samsung 5v2a charger to normal Wyze charging USB cords.
V2, IR off, continuous record, with bridge.
V2, IR on, continuous record, with bridge.
V2, IR off, continuous record, without bridge.
V2, IR on, continuous record, with bridge.
V2, IR off, continuous record, daisy chained to a V2, IR off, continuous record, with bridge.
And finally…
V2, IR on, continuous record, daisy chained to a V2, IR on, continuous record, with bridge.
Test setup is outlet>USB charger brick>meter>first USB cord>first V2 (sometimes with or without bridge, then second USB cable to second v2, with out without the bridge). There are infinite possibilities with combos to run but I just picked a handful. In the numbers provided I am looking at just the voltage and ampage, the others I think apply to more battery banks, if my knowledge is correct.
