Quick Overview

Digital Watt Meter - Power Analyzer - Battery Voltage Checker w/ LCD Screen


Measures and displays key parameters for your elctric power setups (battery, motor, ESC performance)
to help you avoid the possibility of burning out your electronic components due to incorrect propellor selection.

Typical applications:

  • To assist with the correct prop slection
  • To measure the actual values of current, voltage and power
  • To prevent peak currents from damaging your battery, ESC, motor(s), wiring and connectors
  • To verify the operating voltage of your flight pack under load and measure the quantity of charge drawn from the flight or drive battery.

Bottom line, if you want to experiment with differnt props this is the tool for you. Installing a larger prop, even if its only 1 inch longer can greatly increase the load on the electrical system. This meter will tell you what the prop & motor is drawing. Also, for those what want to go from 2 blade to 3 blade prop or vise vera, this is an absolutely a necessity.

How it works... You have a 30Amp ESC and want your plane fly faster, you grab the 1st prop out of your nventory and slap it on the plane. Next you bench test the motor / prop for less than 10 seconds and red the watt meter is drawing 40Amps which is over the maximum amperage draw for your ESC. Now you go back to your box and put on a smaller prop. Without this tool, you can easily see how this prevented a totoal electical failure.

Customer Reviews

Grayson refunded my money. Review by Terry Renyer
When I ordered the digital watt meter power analyser Grayson showed it in stock. 2 days after my order had been shipped Grayson notified me that the item was out of stock and refunded my money on that part of my order. I appreciate Grayson for being honest. (Posted on 12/26/2018)
Great performance, no frills, affordable. Review by Gregory Huffman
This meter does exactly what it was made to do. No buttons to push, just connect it into the plane's power system and you get all of the necessary data to select proper propellers and batteries.
I recommend this meter. I hope it continues to provide good service for a long time. (Posted on 2/4/2018)
Poor assembly of this product. Review by Chris Vitale
When I hooked up the watt meter the LED was upside down. I had to take it apart and turn the LED readout around to the upright position. Poor inspection of this meter at the factory. (Posted on 3/7/2017)
