150A Watt Meter Power Analyzer, High Precision RC with Digital LCD Screen&2 Sets of 45amp Power Pole Connectors for Voltage (V) Current (A) Power (W) Charge(Ah) and Energy (Wh) Measurement

Works great hooked from my porta battery to my Ham Radio

I like this meter. It's easy to read. It's always on so there is some modest current draw even when there is no load. But it's likely very small. It would be helpful if the vendor included current draw in their specifications. But it is a good meter, easy to read, and it appears to be well built.

Just what I needed

Technically is it fine, it does what I need it to do. At a time Power Poles where the defacto standard, but not for some time. The current defacto standard is XT-60, give or take. Would have been a 5 star product if it had come with XT-60 connectors.

I compared this one to the priceyer competing product and can't tell the difference. Both give the same results with the same issues. The display is slightly different, both very easy to read. When placed in series to measure the same load they give essentially the same results. (Yes, one is measureing the total of the load and the other meter. The load side meter doesn't load the circuit enough to make a significant difference in the reading at the power level I checked about 5 Watts to about 65 Watts on an electronically regulated soldering iron - kind of a challenge to both meters because the load is switched.)

The media could not be loaded. Didn't get one use out of it.Initial plug in/start up: it was fine and reading data perfectly.After 10 minutes the display scrambled and is no longer usable at any power setting.(Use was with a UHF/VHF radio at 10watts supplied by 12v3Ah LiPo battery)

if your radio does not display what it sees for voltage. Especially if you are POTA or otherwise needing to run on battery power. None of my radios display the voltage so this is a good way to see how much juice is left. It also keeps track of Ah used so if you have a 12Ah battery you know when it is near the end. There are other interesting stats displayed too. This unit is worth it because (a) it comes with the Anderson powerpoles already attached to the source/load leads and (b) they've conveniently provided additional powerpoles to attach. That saves some money not needing to buy more powerpoles. I have one for each of my go kits.

I've had this for quite a while now but I only use it when I really need it because it's noisy. Whenever there is load attached, this thing emits a constant high-frequency whine (somewhere in the 10 to 12khz range) that becomes very uncomfortable after just a few minutes' use.I just ordered a similar, newer item from a different vendor, hopefully it does not have the same tinnitus-inducing properties.
