I got tired of going through batteries all the time. I decided to try the rechargeable batteries. I checked out a few different battery chargers and decided to going with the "Energizer Battery Charger". It's easy to use, it charges 4 double AA or AAA batteries, its compact, has LED indicators, Its inexpensive and it is cordless-has a fold out plug. I can charge 2 or 4 batteries at a time. I've been using this charger for almost a year now and never had any problems. I bought a 4-pack of double AA batteries and a 4-pack of AAA batteries. I haven't had to buy any other batteries since. I would highly recommend this to a friend!
