Bests & Worsts Reviews from Amazon

This is a very cost effective battery charger. It's a simple flip top design and can charge either four AA or two AAA (You CAN mix them, however you can only charge a maximum of two AAAs at a time). Charge time is generally just over four hours if you charge all four AAs and half that with only two. AAA batteries charge in about an hour and a half by themselves, two hours if paired with AAs. The charger cuts power to the batteries when they're full. This is a MUST feature as it preserves your battery life extraordinarily. It also is switching (100/240V) meaning you can use it outside the US without hassle (Most of Europe uses 220V). The charger comes bundled with four AA batteries with a 2300mAh capacity which is above standard and last longer. If you have batteries under 2300mAh, this charger can still charge them and cut off the power when necessary (The batteries must be NiMH however). My only complaint with this would be the fact that the charger just has a flip up/down plug. If you have plugs sitting side by side facing downwards, the charger will occupy three slots. On a standard wall plug (Side by side with the plugs lying horizontal) it only takes up one plug however. You can easily overcome this by using an extension if needed. All in all, I can 100% recommend this charger. There's another Sony charger slightly cheaper than this one (the BCG-34HLD4). However, pay the extra couple bucks and get this one as the other does not have a power cut off feature. If you need AAA batteries, get the Sony AAA two pack (Model NH-AAA-B2C, Amazon carries them) which are 800mAh.
