The HobbyKing PO Wattmeter is a must have tool for any EP flyers tool box. The meter displays watts, amps and volts on the same screen and also features a hold function that will record and display the peak measurements taken during your testing. At this price you can have one for the work shop and one for the tool box!
Voltage range: 6~50v
Current range: 0~100A
Display: Volt / Amp / Watt
I bought one of these, but it is exactly what it looks like CHEAP AND NASTY... O it works sort of OK, but the display is Crap IT NEEDS A BACKLITE !!! it is impossible to read on a sunny day (I live in Australia, were the Sun shines most of the year :) ) I am now looking for a watt meter that has a LED display not a LCD display .Any recommendations ??Works an absolute treat! Great value. The little voltage display only comes on when the switch is ON. But this can easily be modified by cutting the two wires going to the 7 segment display and soldering to different pads, to always show input voltage regardless of the switch which will then only control the BEC. Wonderful!Never worked - could not activate calibrate function, button to activate calibration feature fell inside casing. Re assembled switch with same result.The button on mine was broken upon receipt, but hobbyking promptly issued a refund without requiring the item to be shipped back.really really usefull, gotto have this, I was WaY of on propping/gearing on a few models, burned engine, bought this to check... wow was pulling 1050 on a 560W motor.Received mine 3 days ago. Works only intermittently. When it suddently decides to work, the precision is terrible. Shows a 1A current event without a load (ESC) connected.
Mine is going back.
Avoid at all cost.schwarzes kabel ist minus blau plus.
netter kleiner helfer.
display knte kontrastreicher sein aber ist ablesbar.
Very useful tool to define the approximately power and the electrical consumption of the motors.
I cannot say anything about the accuracy of the measurements because I did not compare it with any other tool.
The device is very poor made. Start up is very long, screen is hard to see and the button is hardly hold in the hole.
But it is a good tool for occasionally use.Got it a few weeks ago.
Voltage measurement not accurate 1V
Current measurement not accurate 0.5A
Calibration not working.
Hold function not working.
Can be used only if you don't need the Hold and don't much care for the accuracy.
Lasted a couple months and is now DEAD!! No use even thinking of contacting customer support. Will try another brand.
