I got this wattmeter based on price and the built-in PPM generator which I'll use to test ESC/motor/prop combinations. The plastic case looks and feels a bit cheap, but I guess that's to be expected at this price! Mine also has the incorrect "PCM SET" label next to the BEC switch.
My unit did NOT come with the bullet connectors or heatshrink shown in the photo - the meter just has short wires with tinned ends.
My unit reads approx 0.8A low on current (so an actual current of 10A would be shown as 9.2A), and currents below 0.8A read a zero. That means all power readings will be a bit low, but the % error reduces at larger currents so it's not too bad. The voltage reads about 3% high.
Don't even think about using the built-in BEC feature for testing servos. Some of the BEC components are only suitable for a few hundred mA (yeah, I had a peek inside to see if I could trim out the current offset), so you might damage the meter if you test a servo under any load. The same supply regulator powers the wattmeter, so if you see the display flicker or fade that's the reason. Leave it switched off and use an external BEC.

essential bit of kit to prevent you blowing up your expensive lipo,s like I did. Its an inexpensive ammeter/wattmeter/voltmeter all in one cheap package, just connect it to your Esc /brushless motor/your battery and your performance testing can begin. excellent!!

I received the item very promptly yesterday and tried it today, every thing worked as instructions the only fault is when operating in Watt mode, the instructions are not clear about which buttons are the up/down ones I quickly realised they were doubled up with the enter /esc buttons, I think this should be made clear for novice users without electronic knowledge.

The Neodym Multi-function DC Watt Meter
Be aware that the legend on some of these meters are wrong.
There is only one PCM-SET switch the one next to the output power connector.
If yours has the text ‘INPUT………SERVO…………PCM-SET’
read as ‘INPUT………BEC…………PWR-SET’
This is a watts meter not a servo tester.
If all else fails read the instruction………FISRT.

Does exactly what it says on the box. Used a few times now with no problems at all

I like this Watt meter very much. The Dial on the top (PCM) is for controlling the speed of the motor instead of using the your reciever and Transmitter. It seems to be accurate. My ony critisisum would be it needs longer cables they ar very short and awkward to solder.

Item arrived very quickly. I am very pleased with meter, easy to use briliant.
As this was the firtst time I have used Giant Cod it was a pleasure to deal with you.
Thanks Doug Adkins

Arrived promptly from GC as usual. Meter has "PCM-SET" at input and output ends and instructions have "PWR-SET".......confusing.
Some reviewers seem to have tried Servo testing but I had no success, just a buzzing noise.
Works well at the functions advertised but I don't know anything about "Pulse width" or it's functions.

Works a treat and gives me as much info as I need to get the right set-up. Excellent value for money. Well made.

As a basic watt meter it does what it says on the box, but the instructions for the PWR-SET are appalling and could lead to the wrong configuration if you don't guess correctly.

Very good as a wattmeter etc, but DO NOT use it as a servo tester. The first one I had burned out immediately with a brown smell, when using is as a servo tester with a 3s Lipo. [It was not bought from Giant Cod]. When I complained and had it replaced, I was advised that perhaps there was something in the unit that could not handle a servo drawing high current. The suppliers adverts were then altered to remove reference to it being ok as a servo tester. Being very cautious, I now find that I can use it as a servo tester as long as I only use a normal receiver batter for servo power, or a 2s lipo at the most.
We live and learn.

I am only giving this a bad rating because it uses very small and fragile micro switches. In operation the natural position of the unit would be to lie flat on the work surface, with the display facing upwards. The instructions refer to the position of the micro switch as either "up" or "down". With the unit lying flat if you try to move the switch up or down you will break it off, as I did. The instructions are very poor in this respect and should make it clear that the "up" or "down" positions apply only if the unit is standing on one of its longer sides, with the display facing horizontally. Obviously I did not get a chance to try the unit, but I did buy the rival GC wattmeter advertised on this website. This is superior in every way - more functions, higher volts and amps capacity, more robust (metal case, no micro switches). I have used the GC wattmeter several times and I am very pleased with it.

I am a complete novice in electric stuff, and am just dipping my toes in the water. I bought this meter to help me get some experience and to avoid making cock-ups.
The one combo that I'd bought allowed the meter to vitually pay for itself, I had a 1200kV 35Amp motor plus a 50 Amp esc and hadn't a clue what size prop to use. I bolted the motor down and testted a selection of props, finding one in about 5 minutes flat that was suitable for the application I had in mind. BTW I use ic props as they are going in vintage jobs.
The only drawback I found was soldering the adaptors on. I've settled on the new deans plugs and getting a suitably large contact footprint for the cables tested my soldering abilities to the giddy limit.

Great simple to use piece of kit. Build quality is good. Really does take away the guess work. Essential tool if electric flying is your thing. Built in servo tester as Andy mentioned is a bonus. 5 stars all round.

Excellent piece of kit as the other reviewers have said :-)
Only one minor niggle:- the ESC/servo connector could do with positioning on the power output side (RHS in piccies), this side being the one where the ESC is connected to the power thus keeping both ESC connections on the same side & tidy. Just asthetic though - it takes nothing away from the functionality this kit offers.

Very nice meter.
The ESC controlling function (socket for an ESC and the knob at top right) should take a lot of the hassle out of testing motors and ESCs. Juggling a transmitter, a tachometer, a small torch and a notebook was always a bit of a pain.
There's a switch to select the pulse width range (normal 1-2ms or extended 0.9-2.1ms) and another switch to turn on or off the internal BEC. Make sure you turn it off if you're plugging in an ESC that has its own BEC. "Up" in the manual means with the writing at the top... Probably best to add your own label for that switch because there isn't one.
With the internal BEC turned on you can measure the current used by a servo that's plugged into it.
For an ESC, plug the receiver lead into the socket on the meter and the power lead into the output leads from the meter (or do it the old fashioned way with a receiver, and ignore the knob). For testing a servo, just plug it in to the socket with the internal BEC switched on, and make sure the output leads can't touch together, of course.

Just saw this, unfortunately I bought one quite a while ago from A.N.Other supplier. I wouldn't be without this, It's a great aid to setting up your power systems. It measures volts, amps, Watts and mAh used. But the beauty of it is that little knob on the front which sets pulse width to control your speed controller. You don't need your transmitter and receiver to test your setup just plug your speedo into this and turn the knob - great for checking setups on the bench. You can also plug your servos into it to check them.
Rob well done for getting these out at such a fantastic price, they are 38 quids from other places.
