## Verdict

The Energizer Rechargeable AA and AAA Battery Charger with included NiMH batteries is a solid, no-nonsense choice for everyday rechargeable needs. Its compact size, fold-away plug, and reliable charging indicators deliver a fuss-free experience, especially if you use both AA and AAA batteries regularly. Just keep in mind you’ll need to charge batteries in pairs, and the charger supports only NiMH cells. If charging single batteries or faster charging is a priority, you might want to explore other chargers, but for dependable, eco-friendly value, this one holds its own.

**Top pro:** Charges both AA and AAA batteries simultaneously in any combination, which is super convenient.
**Top con:** Must charge batteries in pairs (2 or 4 at a time), so you can’t charge a single battery alone, which can be a minor inconvenience.

## Cons
