Kinda doubt anything that small (AA, let alone AAA) would have built-in charging.
You know that some knob will stick an alkaleak in there and try charging it, with predictable results. :person_facepalming:
Howbow a Sofirn SP10 that comes in red and/or blue? Takes anything from an alkaleak to a 14500 (NiMH/LiFePO4/Li-ion) without breaking a sweat.
