Yeah, the GBA SP would have been a much better example. What an odd connector. I really need to get around to modding a USB-C port on to mine.

I still prefer to buy things that use AA batteries than in built rechargeable ones. Li batteries are almost always the first thing to go.

Yeah, or you can just get a cheap retro handheld with similar stylings that will charge via -- you guessed it -- USB-C.
