Ever wondered exactly how much power is being used by the servos in a model?
Maybe you're not sure if your servos are quite up to the job they're doing, or whether a surface might be stalling its servo?
The HobbyKing™ 20A Watt Meter and Servo Power Analyzer is just the tool to keep in your flight box to take the worry out just these situations.
Providing real-time and recorded maximum and minumum voltage, current and power monitoring, this meter will let you know exactly what's going on with your flight control system.
The unit is simple to use, has a clear LCD readout and is easily switched between modes or reset by using the side mounted button.

I went too long without having a watt meter. While the sampling frequency means that it may not be perfectly accurate, I soldered some adapters and used it to test the battery draw on my 2s and small 3s foamies, and it's REALLY useful to get real data! I still need accurate readings on some of my heli servos and haven't tried that yet. It may not give perfectly accurate momentary peaks, but I feel like by just watching it you can get a pretty good sense of the average peak, if that makes sense. For the money, it's good either way.Got one of theese, always shows wrong Amp values, voltmeter also not too accurate.
Amperemeter very slow, means, a peak in current, typical for servos, you will never see.
After 20 min working, the product shows nothing anymore.
Could be a nice instrument, if an optimized software comes in and if it gets reliable.
Work on it.
Thanks.With a different connector, this can be used for testing motor and other load, not just servos. I do recommend everyone to get it, since it's cheap, and can percent a lot of pain with servos.This is the item you must have to analyse your servos. Its a must have for every rc enthusiast,Very tiny watt meter, perfect size. easy to mount and use. Its provides the power consumption by the servo.
A MUST HAVE WHEN SETTING UP ANY SERVO, SUPER CHEAP BUT GREAT QUALITY, I HAVE 3 OF THESE NOW AND ALL OF THEM HAVE BEEN WORKING PERFECTLY!just recived Instrutions would be Nice !! checked several servos in model some times get a reading ?? but varies so mutch not sure what the readings are telling me ? while operating them some times no reading at all ? then does ,do you have to keep operating the servos to full travel constantly to get a reading ?? a little confused !Ich habe eins dieser Wattmeter gekauft. Anzeige immer 1300A !! also, defekt und zurck geschickt. Trotz mehrfacher Nachfrage kein Ersatz und kein Geld zurck. Ich bin zum erstenmal vom Service entteuscht. 2 Monate spter das gleiche Messgert noch einmal bestellt. Beim Anschlu eines Serves mit zustzlich dazwischen geschaltetem Ampermeter zeigt das Ampermeter 300mA an und das Wattmeter 2,5A!!! also ein total falscher Wert.
Schade, ich war bisher immer mit HK zufrieden, aber dieses Wattmeter ist fr die Tonne.
Ich werde es nicht zurck schicken. Die Portokosten wren dann auch weg.Good stuff to measure the servo power consumption.
Very usefull !This is a great little meter for testing receiver and servo loads. Min/max readouts for voltage,current , and wattage are cool. Small enough to fly with model if necessary.
