Have you tested that is actually ABS? Is it burning because it's mislabeled something else with a lower temp range?
If it is really ABS, mix with acetone to make a slurry for bonding abs parts. You can also cast parts in molds from the slurry with limitations.
Lol, the idea what a battery powered device is a camping to for starting fires is just funny to me. Of all the ways we have to start fires one that requires a battery is the last thing I'm wasting weight and space on when camping.
