Ends the guessing about your electrical system's behavior.

The Watt's Up Watt meter is used like jumper cables.

It lets you easily measure EIGHT electrical values that tell you what's really going on and give you control of your electric RC model's operation.

Troubleshooting a problem? "Watt's Up"'s measurement abilities help you find an out-of-spec current or voltage that may explain a crash or damaged component. The possiblilities are endless.

A low cost yet precision instrument, "Watt's Up" replaces an:

  • ammeter,
  • Amp-hour meter,
  • wattmeter,
  • voltmeter,
  • Watt-hour meter,

and does more while costing less.

Try our Wattmeter simulator and see how it works.

watt meter review

You Need One!

Why you need a RC Watt meter.

Just wanted to let you know I LOVE this meter! I'm playing around building CD ROM motors and the meter makes it so easy to objectively evaluate the performance of each motor.


I am also very pleased with the size, construction and ease of use.


Thanks for a great product! - T.S.
