I have the 3rd generation of this charger and I’ve had this charger since about 2013. It was inexpensive but still works well and is awesome because of the multi-chemistry support. It came with a cigarette lighter adapter for direct DC input which means it was designed with typical automotive voltages in mind. It can also be powered directly from 100-240vac. I take this charger on every trip with me for charging on the road and once I’ve reached my destination.
This charger is capable of charging the following types of batteries:
- 18650 and similar size lithium ion cells
- AA/AAA/C NiCd/NiMH cells
