This is a good charger for my 21700s, 18650s and eneloops. Ports 2 & 3 are 1.0A if two Li cells are being charged. 1& 4 are 2.0A for 2 Li cells. If 4 Li cells are being charged then all 4 ports are 1.0A The X4 charged my AA NiMH eneloops at 0.5A in all ports which should give me more charge cycles out of my cells than the 1A I usually set my Powerex NiMH charger to for eneloop white AA.It detects the cell chemistry and sets the charge current requiring no user intervention. If charging 4 Lithium cells and one doesn't want to subject any cell to the higher 2A charge current populate the middle two ports first. It's be cheaper in the long run having more cells and charging them at the lower 1A than at 2A. Despatch was same day and I ordered 14:50
