The really cheap ones I have off ebay take forever to charge up my spare batteries for my galaxy 5, like 6 hours or more, which is faster than the phone uses them sometimes.

Is there any desktop chargers available that will charge in a reasonable amount of time like an hour or less? Ideally USB powered so I can have one in the car too.

I have tried a generic plugin charger with 2 movable pins on it, and it also is really slow. I am guessing as they dont connect to the thermistor pin on the battery that they keep the current really low so to never overheat the battery.

What kind of batteries are you trying to charge? Aren't chargers very make/model battery specific?

One of the samsung sizes that look like the nokia cells - same as the i9000 and many others take, but they are all just lipo cells, so there is no reason that they have to be cell specific other than the locations of the connections.

I am tempted to just gut the circuit in the cheap ebay charger and run the connections to my hobby charger that I use for other lipo packs, but would have to make sure I remember to turn the current down when charging the tiny phone batteries. Thats why I am hoping there is something better than a $4 ebay charger that will do it fast but monitor the temperature of the cell.
