Replaces 100 AA batteries. Good enough for me to buy.

The ENERGIZER B QUICK CHARGER should've been called The ENERGIZER COMPACT QUICK CHARGE AND EXCESS BATTERY ELIMINATOR. This has been one of the smartest purchases for cost-efficient savings I have had to date. You also have the option of buying this charger equipped with four double A 2500mAh batteries.
No more battery purchases for small cameras and other gadgets, Energizer's improved QUICK CHARGER has definately saved me more money then it actually cost,(Literally hundreds). No more running out in the middle of the night to find batteries because toys and dolls stopped working, (the love we show our children). Just plug in, wait five minutes, plug out. That simple.
This compact charger measures only five inches tall when fully opened, and drops down to only three inches when closed.

FEATURES
This compact charger can transform into a wallet-sized "mini briefcase" to carry in your pocket or purse. The prong for the outlet even folds and clicks securely into the charger, keeping it safe from breaking off.
This charger takes less than a half hour to fully charge a set of four batteries that have long since had no juice. It's green detailed bright indicator light gives you reassurance that the charger is charging and goes off when the batteries are charged.

CONS
Upon first receiving this charger, It wouldn't charge two batteries. Waiting for days and starring at this charger for the green indicator light to come on,(like bubbles on finding Nemo,"Bubbles!"). It finally donned on me to try to put all four batteries in their respective compartments. WAAALAAA!
It worked. Nowhere on the directions does it say all four batteries need to be placed in the charger for it to work.
It would've also been a better idea to also have the compatability to charge other sizes, like triple A's, 9-volts, and other commonly used sizes.
you cannot store the batteries in the charger's compartment when closing it. This is an option that would've made this product true to fame. you need a different storage for the batteries.
