RGBZONE 150 Amps Power Analyzer, High Precision RC Watt Meter with Digital LCD Screen for RC, Battery, Solar, Wind Power

This is working exactly as intended. Measures real-time, peaks, and total accumulated power. Similar models seem to sell from US sellers at between 14-18 bucks, so it's $16.xx price is acceptable.My wish list might include a better, brighter screen but it's fine and easily readable in most situations. This really was a plug and play power monitor. I would buy again.

This works well except the peak readings are always the current value. It's not storing the peak value. Anyone else having this issue?

I use this to keep track of my power production with a small solar panel setup (portable Rockpals 100W panel with their 300W battery backup system). It works great and gives me the information about how much power the panel is producing. very nice setup. I had to order some MC4 connectors to be able to attach it inline between the panels and the battery backup but that was pretty simple to do after watching a youtube video. All in all a great product and I'm very happy with how well it works and how accurate it is.

Instantaneous values seem accurate.Fails to retain peak values as others have said.

it is only fair that i update my review now that the product actually arrived. Dispite the order arriving too late for the project that was dead lined, the i love the meter. it works great and exactly what i needed. it is a great value as i looked at several on amazon and this was 4 pages in. It is definitely worth the $20.00 and displays volts, amps and much more. I only bought it for the amp function. my first review about the shipping still stands. it was unacceptable that you changed carriers the day of delivery causing a delay but the vendor does sell a great product and i feel bad about the first review. product 5 stars: shipping no stars, 45 minutes on phone with 4 different people and 8 e mails from amazon: worthless.

The voltmeter and ammeter readings are correct. When I checked the Amp Hour measurement, the display reads only 58% of the actual amp hours consumed. Since the ammeter reading is correct, the fault may be that the internal real time clock is running VERY SLOW. I thought perhaps I got a bad unit and since there was no way to contact the seller so I ordered a second unit. Exactly the same problem. Amp Hour reading is no where near accurate. Have to return them both.

This is an exceptional value when compared to the PowerWerx wattmeter that's over 3 times the price. Does all of the exact same functions. Built exactly the same less power poles. LED meter is plenty easy to read.I will echo the complaints of others. The wire leads on this are quite frankly too short. They're only around 2" long on each side and that's barely enough to work with for most applications. Also the tinning on the wire was too heavily done so the wires had to be trimmed to fit in a 10AWG yellow spade connector. For those reasons combined I dock 1 star to a 4-star rating.This unit would be improved if it had a way to save and manually clear previously recorded values. It's not something I expect at this price point, but it would be a nice feature if it ever sees a revision.Overall highly recommend. Throw your own Anderson or spade connectors on it and it's a great addition to your power sources.

Product was very easy to install. Although the wires are probably half an inch to an inch too Short on each side forces you to make a connection in the middle of things usually. I think if the wires were in half an inch to an inch longer on each side it'll be less chance of having a connection last chance of shorting out and so on other than that the product seems to be a nice little product working well but I did have to make two connections on each side in order to connect it to my system.

Reads voltage well, but current and watts jump around constantly. I'm guessing this is because I've got it connected right after a rectifier without a filter circuit to smooth out the ripple, so that's on me. Would be nice if they included the female DC adaptor plug or at least mentioned the name of it in the instructions for those of us who aren't electronics wizards. Would've gladly paid an extra $2 for it. For the record, the plug is a Futaba J, JR, or HiTec style plug. Other than that, it arrived on time, undamaged, and works well.

Using this meter I was able to find that my RV refrigerator was running 95% the time and drawing 60 watts thereby running down my battery. I installed a new fridge and this meter proved it was drawing only 30 watts and running half the time. I can sleep well now. This meter was well worth the cost and the effort.

Good device to estimate juice left on a battery or measure the consumption of a device or measure the power produced by solar panel over the course of day.It would be great if it have a memory so you can test until sun goes out without external power connected to the unit, but for the price it is good enough.Is it the most accurate decide ever made? Not at all, but nobody needs 5 decimal place of accuracy to evaluate how much is left on a 100Ah battery. Or to characterize a charge profile of the same battery on solar.It is good enough for a home usage and cheap enough for not being sorry if it falls on a rock ground in the field.

I have 4 of these, bought 2 from this seller, useful and low price but the Volts/Amps measurements are off and unable to adjust. The 2 ones I purchased from this manufacturer are the worst, the Amp reading shows 0.220 Amps with no Load at all (disconnected). I guess these are for RC (Remote Controlled) Cars/Trucks and accuracy is not important. Disappointing. Don't expect too much.
