Connect my wife's one-week-old HTC One phone to my week old Anker Astro 5600 mAh external battery charger. We were out at an event and she was down to four per cent (4%) battery. She plugged in and tucked the whole thing into her bag we checked it about a half hour later. It had charged about to about 50 or 60 per cent, but it was very hot to the touch (more than just "warm" more like holding a hot coffee cup) and when we turned on the screen we read the following message:
"The power adapter you connected is not compatible. To avoid damaging your phone, please disconnect it now. Be sure that you only use manufacturer-supplied power adapters with your phone." With an "OK" button at the bottom of this dialogue.
Anker is a pretty ubiquitous name in chargers. I've used this charger on my Samsung Galaxy Note II with no problems, also on a couple of other devices without problems. The Anker charger is only a 1 amp output, the wall plug charger that comes with the phone has 2 (actually 1) Amp(s) of power output for the devices it charges. The HTC One phone is "stock" (not modified in any way what-so-ever.) The phone is so new that I don't think any games have even been loaded on it yet.
I also noticed that when I plug the phone into the Anker external battery that the HTC One's battery indicator starts to quickly flash the lightning bolt inside the battery icon about eight or nine times before it flashes the warning message and eventually settles down to charge.
Odd behaviour.
Immediately after the overheating incident I unplugged the Anker external battery and rebooted the phone. No problems since then. I have a laser/infrared thermometer and it shows that normal charging temperature seems to be around 28-30 when running and charging, and usually a few degrees colder when the HTC One phone has been turned off and is charging.
