Good standard charger, it charges my 4 2700mah batteries 14h, what I prefer a fast charger which often charged much less well, at least here they hold a charge longer, ideal for use with a camera flash SB900 kind, alternating with a second set of batteries. Just one regret, I thought the "back burner" indicated the end of the load, no-no, it's just a night light with on / off button, it will be necessary to check the time for when the battery has finished charging . It is also a pity that the electrical plug is not pliable as on some models, so he is difficult to store in a camera bag. Otherwise, good standard charger.
