Sorry, the topic should read (mA) not (ma). The forum forces char cases.
i power my wireless pads with 2x2000mAh cells. The backside of the wireless pad reads '5V - 450mAh'. That might be maximum input current i think.
But what is the real median current flow of a wireless controller (like 50mA = 4000mAh / 50mA = 80h)?
I grabbed my ampere meter and some acrobatic skills and measured some 22.76mA during idle. It doesn't really raises when pressing buttons or sticks but when leds are changing (low battery) it raises to 26.7mA. Rumble not tested.
So 4000mAh / 22.76mA = 175,75h = 7,3 days of continuous power.
These are just some fast/draft values of course. My cells (alkaline) are quite empty currently. Not sure if it pulls more if full (with more voltage).
