I've been using one for about a month, works great. It would be nice if it came with and AC power supply. I've been looking for one but have not found one with sufficent amps (in a small plug in DC power supply).

Someday, I might put a cute statement here.

Ive used quite a few chargers in the same price range as the THP-425 and have found it is by far the best of the bunch. Its very high quality in a small, robust aluminum case with ease to see LEDs. It also has easy to use push button controls (no silly little jumpers to lose like Apache, Kokam, etc chargers) and numerous safety features. Also, the THP charger charges my packs faster (the same fully discharged, after hitting cut off and not overdischarged, pack at a 1C rate on some chargers can take 1.5 - 2 hours to charge, but the THP routinely takes 1.15 - 1.25 hours saving a little bit of time due to its improved charge algorithm).

You definitely wont be disappointed if you pick one up!

Had mine for a couple of weeks now, works good, no problems with it so far. Like having to push the buttons to set it up and charge, got a apache that works great to, but there is a possiability of charging wrong cell count and amps because you can just plug in and start charging, so if your charging more then one type of pack you got to remember to change pins for the different cells, while the tp you have to push the start button on it so you can check if the cell count and amp input is right, while its in your hand.

I bought the TP-425 as a second charger a few months back. The first charger I bought was the Duratrax ICE charger. Anyways, with the tp-425 my voltage on the tp 3s 2100 at the end of the charge was 12.55 and on the ICE charger it’s 12.60. I’m not sure if this is normal for the tp-425 or not. These results are the same for the four tp 3s 2100’s I have. But if I had to buy another charger it would be the ICE charger.

With a calibrated fluke 77 my 425 takes the 2100 packs to 12.56 , so I'd say .04 difference is about 10 secs maybe, not worth mentioning.

I noticed my Thunderpower 425 charger charged my packs up to 100% capacity. In fact in comparison to my Astro 109 which charges between 93-95%, it charged the packs more. Although you may get an extra second of flight time, charging at 100% is worse for your battery then charging it to an almost full condition. I just sold my Astro 109 as I really prefer to just plug in my pack and push a button and walk away, its simple, light, small, and cheap.

Here you go.
http://www.thunderpower-batteries.com/THP-425.htm

And here is a great review/article that is better written than the manual. (scroll down a bit)

I should add that my TP-425 has performed flawlessly and I highly recommend it.
