How do I charge the device when it's near 0 power?
At first everything was going well, and it was charging; I had it plugged into a low-end charger, same as I usually use for it in the car (around 1.0A). Then I noticed the maps needed updating, and I figured, since I was indoors, I would make use of the household WiFi to update. Big mistake. I guess, while downloading, it was using more power than it was charging; it quickly ran itself down to zero power again, I guess mid-update? And now it won't come on again.
When I plug it in, it cycles through powering itself up, and then switching itself off again almost immediately, like it's immediately exhausted its power supply. I never get enough time to actually push the button and turn off the device manually, so it can charge, so this pattern continues to repeat itself, and I'm worried that if I leave it doing this, it will damage the battery.
I've also tried hooking it up to the lightning adapter I have for my Apple gadgets (2.4A), in the hopes that the increased power supply might offset the usage, but it seems to make no difference.
Is there a way to get around this problem and charge it?
