Customer Reviews
Great meter - does exactly as advertised By Guest
I use this meter in two main modes: measure power delivered from a solar panel to charge controller; measure voltage and Watt-hours from the battery to my DC bus (rig, usb devices, etc.). Works perfectly.

Benchmark Your Rig By Teodros
Fantastic device for tracking specs on your rig. Ah metric helped me nail down what size battery I would actually need in the field.

They Increased Display Brightness! By Greg
Sometime between the summers of 2020 and 2021, they increased the display brightness significantly so it can be read much more easily in the the field! I'm not sure how much internal power is required but I've compared this new version to my older, dimmer version (from last year) and the readings seem to be identical. Kudos to Powerwerx for listening to their customers who complained about the display brightness. 73 KJ6ER

Problems reading display values by Ben By Guest
Some of the other reviewers expressed the same problems with reading in sunlight and update speed. Otherwise it would be nice to select which parameter that one is interested in reading. In my case, it would be AmpHrs so that I know the remaining Amphrs in my battery in my pontoon boat.

Does The Math By Guest
It does exactly what I want it to. The only thing I could wish for is a lower price tag... but I paid it so that proves that, to me at least, it's worth it.

Good but... By Guest
Handy, many features. Why not have the male terminals inside the unit enclosure... Unfortunately for us in one of the African hell-holes just tooo expensive (multiply USD with 15 and add 30% import tax... Don't forget to add approx USD15-25 for p&p.

Perfect in my radio shack... By Guest
I have this little gizmo hooked up between my powersupply and my DC connecting point in the shack. I would have expected longer cords but thats a minor problem.

digits poorly allocated By Guest
There is one thing to be aware of in this meter: it rolls over at 65 Ah.
That means that if you are trying to measure some period of time wherein more than 65 Ah pass through, you will get a goofy reading and you will have to estimate how many times it has rolled over and add back all that missing quantity.
It works in as far as it works. But the builder missed an opportunity to do much better. There are 5 digits in the display; it reads up to 65.535 and then rolls over to zero, which is silly because all future readings will henceforth be wrong. (Depending on how much current is drawn, this may take minutes or hours or days or seconds.) If the device was redesigned to use all 5 of those digits optimally, it would keep counting up to 65,536 Ah, which is a thousand times more useful!
The device works as advertised. But I have to read mine 4 times a day to be sure to catch all the rollovers. Without any change in hardware, it would be much more convenient ... I could read it once a month instead!

Excellent meter! By Guest
This meter provides outstanding information including voltage, amp-hours, consumed, Amps, and Watt-hours consumed. It is extremely useful for ham radio (and also various other applications).
Was this review helpful? Yes No (20/12)
Not a bad meter By Guest
I am happy with the meter but wish the display sequence was slower, perhaps changing once every three seconds. Maybe even a way to toggle through and have it stop on which reading you'd like.

Watt meter By Kemp
I'm using it to measure power delivered from my solar panel to charge controller. It seems to work okay. I like that it keeps track of the peak values and the display cycles through the parameters its measuring. I have a couple of suggestions for future improvements however. Daylight readability of the display is difficult as others have mentioned here. The other issue I had was that the plastic window in the case does not tolerate temperatures that you would encounter in a closed car in Florida. After one day in the sun, the window distorted and now has 'humps' in it.

Not good in daylight applications By Guest
I recently purchased the Powerwerx Watt Meter, DC Inline Power Analyzer to monitor my trolling motor. The problem with this product is that the screen is completely invisible or unreadable in normal daylight applications. The screen is only visible indoors with artificial light or darkness. That means this meter is useless in most outdoor applications.

Very Nice By Stanley
Very nice meter and performs as advertised. I also wish leads were a bit longer maybe total of 8 to 12 inches. Display can be a tad difficult to read in very bright sunlight.
Was this review helpful? Yes No (55/9)
Good Product By Craig
Performs as advertized and does everything I need it to do. My only issue is the display, I prefered the old green display as I found it easier to read.
Was this review helpful? Yes No (46/10)
Almost perfect!!! By herb WB6FHN
Meter does exactly what I need and more but, a 4 1/2 stars because the leads could be about 2"-3" longer. IMHO
