This is the DuraTrax Onyx 210 AC/DC Peak Charger w/LCD display. The Onyx 210 charges anywhere from 4 to 8 NiCd and NiMH batteries, with output current selections of 800mA, 1.5A, 3A, and 5 amps. Great for charging batteries for 1/18th to 1/8th scale electrics, nitro receiver packs, and even transmitter batteries! A tiny, lightweight built-in switching AC power supply plus DC input capability is perfect for use at home or the track. A custom LCD with backlight is great for use indoors or outdoors, daytime or night. The Onyx 210 has more applications (and convenience) than nearly any charger in its price range!

  • A super-small, lightweight built-in AC power supply is great for cramped pit spaces, and easy portability.
  • Selectable charge currents of 800mA, 1.5A, 3A, and 5 amps, with an auto-trickle function.
  • A custom peak detection system loads NiCd and NiMH batteries full of power.
  • Pushbutton controls and audible tones make for easy setup and control.
  • Large alligator clips on the DC input easily connect to most 12V DC power sources.
  • A backup safety timer automatically stops charge to prevent accidental battery overcharge.
  • Includes a built-in output lead with standard plug. An adapter is available separately to connect batteries having a Deans Ultra Plug.
  • Solid-state reverse polarity and current overload safety devices ensure trouble-free operation and long duration.

DuraTrax Onyx 210 AC/DC Peak Charger w/LCD Display
Recent purchase from aMain. I like this charger. I run nitro, so my only need for a charger is for a NiMh receiver battery. 5x1400mAh. Onyx 210 meets that need without breaking a sweat. The back light feature is an unexpected plus. Seldom found in a charger, but much desired. Dual voltage is another plus. 12vdc works as back up for me. 115vac is primary. As an option, I also power up this charger using a 750watt power inverter jacked into the power plug in the back of my truck. My inverter puts out a modified sine wave for ac power. Some electronics don't like this. The Onyx appears unaffected. ONE CAUTION: The 210 defaults to a charge rate of 5.0amp. Not a big thing once you know to remember that. I just hit the settings button and select 1.5amp. The port for accepting a receiver battery is great. No adapter needed. Another plus. Would have liked a sticker as a reminder to jack in with the (-) to the right side of the port. Again, no biggie, a Sharpie penned it in as a visual reminder. Bottom line. For the price and for what it was designed for, a buyer can't go wrong. Thanks to both aMain and DuraTrax for recognizing that there are still NiMh receiver battery users out in the nitro ranks.
