I have a Quark Micro Drone. Here’s photos of the small drone and charger.

What has me concerned is the charger. The instructions say to charge for 30-45 minutes on a USB port.
If the USB port is charging at 500ma, that would be awfully close to 2C. I have heard that’s max speed for charging?
And I don’t know if it tapers off, or just puts 500 ma constant charge in there.
Haven’t been able to find specs on the battery, but one company sells replacements marked as 300 and 500 mah. Sounds about right, tiny battery.
If I could find the right connection, I could use a cheap Chinese charger that gives 200-300ma. But I don’t know if that slows down at the end, either, was just testing on a 18650.
Advice? Specs? Etc.?
