Jimmy: Have solar panels for rechargeable generators. I used to get readings for volts and amps before connecting to the units. Some have a max input for charging.

Robert B.: The meter worked for 3 hours and then screen is all blue without any readings. Total waste of my time and money. I do not reccommend this product.

Amazon Customer: I've been using a borrowed one for several years and decided I should get one. The new one looks just like the old one, works the same and no reason to think it won't be just as durable. The pigtails are nicely soldered and easy to put connectors on, such as Anderson pole.

AlexAlex: wattmeter was good and measurement accuracy and for smaller current i would highly recommend. Easy readable screen, good information displayed and good materials used. Used it for 4 months already and so far no issue.

not so good (if i can say it this way):
- I mentioned small current because at more than 50A, the wires tent to get hot (1+ hour). Would not go beyond 100A (currently used at 24V) unless larger wires
- connecting wires could be 1 inch longer to support installation of various connectors and easier crimping

Another Movie FAN: This unit had potential - for example, the backlit yellow/green display is beautiful - and the manufacture did make the crappy CCA wires a tiny bit longer - and added some vent holes to help keep it from melting down (with a warning NOT to run more than 50 Amps on your "200 Amp Makerfire" meter unless you want to MAKE A REAL FIRE) -- but it's pretty obvious that they did ZERO overall QC testing on the design because there are some really silly-stupid issues that would have been easy to fix - but they just didn't bother.

The first issue is the accuracy for current (A) measurements below about 1 Amp is REALLY BAD. The lower you go the worse it gets, with the reading going to ZERO when there is still over 100mA flowing. This offset error won't create a huge error if you are measuring 10A - 20A flowing in a fairly high power circuit, but at high power levels the accuracy of the internal current shunt starts to become an issue, all of which makes the meter pretty much useless for any kind of high accuracy current measurements. This also trashes the power measurement accuracy since the reported power is calculated using these inaccurate current readings.

That's really bad,...
