No matter what kind of R/C car you own, you need to charge your battery packs. Duratrax released a new line of budget chargers, the Onyx.

To test the Onyx 230, I first charged few 1600 NiMh receiver packs that I use for my nitro vehicles. Navigation trough the menu is really easy and intuitive. I programmed the Onyx 230 according to my packs specifications. Few clicks on the panel and the charger was ready. The LCD display with backlite is easy to read. Few minutes later, the first pack was fully charged and slightly warm. Sign that the peak detection has stopped the charger when the pack was perfectly charged.
Here what comes with the Ony 230. Instructions manual, AC cord and a Tamiya style connector
I pushed the test a little bit further by charging an old 2400 NiCd pack that was lying on my work table and collecting dust for many months now without being charged for a very long time. I was a skeptic with this pack. I slow charged it at 1.0A, almost two hours later, the charger beeped. The pack was warm but not excessively warm. I installed the pack in my Wheely King for a test run, the pack lasted more than 9 minutes, sign that the Onyx 230 has charged this old pack with perfection… Once again.
For the last test, I charged a receiver Lipo pack; I programmed the charger according to the instruction manual. It is always safe to read manual when it is time to charge Lipo packs. Like with others packs charged for this review, the charger fully charged the Lipo receiver pack. The Duratrax Onyx 230 charger works as well with NiMh, NiCd as it does with Lipo.
AC/DC cords, the cooling fan is located at the right.

- Small size
- Internal fan
- 5 years warranty
What could be improved
- Can’t find a thing
The Duratrax Onyx 230 is a perfect charger for any R/C enthusiasts of any level. It worked flawlessly with all the packs I have charged and never gave any false peak detection. It can charge all type of batteries on the market up to 7.0A (5.0A on AC). Its small size let you bring it everywhere. This is an excellent budget charger that will suite all your needs, no matter if you are a nitro or an electric racer. It really worth the 80$us asked for.

I had issues with the charger, it was impossible to fully charge any packs with even after multiple tries. I contacted Duratrax to explain to the problem. I sent the charger to their service depot. After two weeks I received a brand new charger free of charge, under warranty. Duratrax provided me GREAT service and support.
