ok so more v = more charger faster

will charge up a lot faster if it’s connected to a 5V supply vs. a 2V supply.

can be charged up and then throw it in your backpack.

why cant you juts leave the powerbank tho, it doesnt sound like you actually need it after you use it?

and that powerbank is meant for use at the wall eleticric outlet

can use to charge up other rechargeable items.

so the powerbank has a V, how do we know how much V it has tho, do the sites tell us?

or is it the 'wall box' thing that has the V

nothing comes up for this 'wall brick' besides https://en.wikipedia.org/wiki/Brickwork

is that the 'wall brick' we're talking about or does it have an actual name?

also so doesnt this and these powerbank come with a 'wall thing'?

and i think the last thing was are you able to charge 1 device into 2 poewrbanks?
