Review on IMREN 18650 Battery Charger: Fast Charge for 3.7V Lithium Rechargeable Battery, Ni-MH/Ni-Cd AA AAA C Battery, 4 Bay Charger by Rhonda Babson

This IMREN 3.7V lithium smart charger does what I need and doesn't overheat. Charge progress indicators make it easy to see how far each battery is in the charging process. There are three selectable charge rates, although I am very careful with lithium batteries and will only use the lowest setting of 0.5A, the output is 2A. Sliding bottom posts allow you to use it for lithium batteries (Li-Ion and LiFePO4) of different sizes. The packaging also states that this charger will properly charge a variety of sizes of NiMH and NiCad batteries (from AAA to SC and F6), although I have not tried any of them. The packaging also clearly states that the charger will charge four 3.7V or 1.5V cells simultaneously at a low charge rate (0.5A) or two 3.7V cells simultaneously at a medium charge rate (1.0A) charges. or one 3.7V high charge rate (2.0A) cell each.
