At about the same price as the VP1, it’s a pretty flexible charger. It does LiFePO4, Li-Co and Li-Mn chemistries, covering cells with voltages of 3.2v, 3.6v and 3.8v (4.35v cells.) Charging rates are 250mA, 500mA and 1A and it does USB OUT at 5v/1A. It’ll do 26650s and things down the the 10440 size.
For now, I’m not doing LiFePO4 cells, but I now have some LG 18650 D1/E1 4.35v (3Ah/3.2Ah) cells that are working out well in the charger and in my lights.
