Anyone know if it's possible to wake up a USB battery pack that has gone to sleep?
I'm using a battery pack to power a blinker circuit, but the pack goes to sleep like right away. I was hoping that the blinker circuit drawing power would be enough to wake it up, but apparently not.
Most of what I'm finding when I search for this are ways to keep the battery awake all the time (for powering low-power circuits), but I really just want to wake it up when I'm actively using the blinkers, and let it sleep otherwise.
In the long run I need to find a different way to power the blinkers anyway — either pulling power directly from the ebike battery (if I can get a line in there) or switch to using like a drill battery or something.
I'm thinking that in the short run I'll just plug in a second circuit that just burns the minimum amount of power to keep it awake, and unplug that circuit when I'm not actively riding the bike.
