Reading another thread, I've learned that the smartest way to power a NeoPixel strip via battery is one of these 5V USB battery jobs. Fair enough. However, I'm curious as to what I can expect performance wise. I've got one project in mind which will be "about a 1m strip" give or take, and would like to use the 60 LEDs per strip version. A more ambitious one will use about 2m on 2 sides of an object (total of 4m). Something tells me I'm going to need the 30 LEDs per strip iteration on that one, due to power. There's a chance I can cut it down to 2m x 1, but I have to think about how to mount it and whatnot. This is an update to a successful LDP8806 project, where the signal was split right off the breakout board and mirrored on either side. It was a bit of a hassle though, to be honest.
Anywho, I'm unedcuated when it comes to currents, but am not afraid to read, if anyone wants to point me to a nice primer. :)
