My nook HD takes a nonstandard plug. The after market charger I have has a now broken ground wire right at the solder glob that leads into the plug. It is a tiny fiddly space. I would prefer a less ganky charger. Actually I would prefer being able to mod my tablet to take a standard USB plug however I doubt that is easily accomplished.
Fortunately my stepdad has a soldering iron and I can access the plug’s wiring easy (clipped together rather than sonc or glue so it pulls apart.
For now it SORTA works. Trickle charge with so could be worse.
