How did I live without this?
I use a lot of rechargable batteries in cameras, lights, etc, and my older chargers were a pain because batteries had to be charged in matched pairs, and I could only recharge four at a time. Since I've bought this unit, I can charge anything from one to twelve batteries at a time and I don't need to worry about mixing and matching, whether itsnear full batteries or near empty, AA or AAA, 800mAH or 2400mAH. I just drop them in the slots and leave it to do the job. The display shows a charge status for each battery, so I can see at a glance which ones are fully charged and take them out for use
