Power2000 AC/DC Universal Battery Charger

Finally, a charger that handles both my power tool Li-Ion packs and household NiMH AAs without needing a separate device. The car lighter plug is a lifesaver for road trips, and the wall outlet option means I can use it at my desk.

Swapped out my old one for this and finally I can charge both my 9V and AAA lithiums in the car on road trips, which the wall outlet never covered. The dual AC and DC inputs are the reason I grabbed it, and it's handled every battery type I've thrown at it without fuss.

I was a bit skeptical buying a charger that plugs into both a wall and a car lighter, but it took my AA NiMH cells from dead to full in about three hours without getting warm. The dual input is genuinely handy for road trips, and it's handled my Li-Ion and NiCD batteries without any fuss so far.
