Universal Cell Phone Lithium Battery Charger with USB Power Port (US/100V~220V)

Pros: Bought this charger for my brother to charge his T-Mobile G1's batteries (he has 3 batteries). This charger works very well. It's status LED shines magenta when charging and turns blue when charging is complete.
The charger is actually very thoughtfully designed. The bottom lip is spring loaded and can rotate to accommodate various battery sizes. There is a dummy peg (the blank beg to the right of the pegs with charging contacts) to keep the battery level so both charging pegs make even contact.

Cons: Non so far.

Other: Very well designed and useful universal Li-Ion charger at a great price. Highly recommended for any flat Li-Ion charging needs.

Pros: very small, has status led, can take bunch of batteries, construction seems solid, slide mechanism seems solid, has normal pcb (bunch of analog electronics on it, where only resistors are smd)(sorry I'm not an expert, but I suppose it can easily be repaired if something goes wrong). And it does, read on....

Cons: appears that it doesn't have polarity check. I think I've maybe accidentally inserted my samsung battery wrong (for some reason it had different polarity from my other nokia battery), it sparked and now it doesn't work.
I suspect it could be blown condenser and its yet to be inspected.
if you live in eu you need additional plug and it loses function of folding plugs in itself

Other: handle with care (polarity) and you have pretty neat and versatile charger.

Pros: - cheap but well built;
- keeps battery firmly, has an original rotating battery holder, fits most batteries;
- has colored status indicator;
- no trickle-charge for LiIon.

Cons: - low charging current, not really cons for me;
- no CC/CV charging algorythm;
- sliding contacts have no polarity marks;

Other: handy charger. i think it worth its price.

Pros: Cheap , and good for charging all battery have a pcb :D old style solution , great for my DIY project

Cons: All chargers present evident sign of using! one of three is yellowed e la molla is rusty!!! seems fragile on polarity for EU user , remember to buy an adapter Build quality 2 ,because all are used and with scratches and imperfections

Other: Finally, they work, you can buy because they are cheap, but you can will receive used products :(

Pros: Low price. Buen producto, tiene conexion USB, par la carga de dispositivos moviles, tabletas, libros electronicos etc... no se calienta, el chasis de plastico parece resistente, yo lo recomendaria.

Cons: non-European Connection, So you have to buy another accessory for your connection, and it increases the pressures of the article.

Other: my recommended
