  • Handles 0 to 60 volts. Works on 12, 24, 36, and 48 volt battery bank systems
  • Extremely low power consumption of 6 mA. More efficient than any LED meter
  • Digital LCD screen gives clear crisp number readings
  • Handles up to 150 amps intermittently and 75 amps continuous duty
  • Connecting load end to the battery provides real-time battery charging reading

A decent power analyzer for cheap A pretty decent power analyzer. I like the back-light and it is indeed a reversed display as shown. I doubt the 150amp rating...maybe for 1 second, but it is otherwise beefy. My only complaint is that when the unit is powered off the juice it's analyzing, it will not tolerate a slow voltage ramp up...ex 0 volts though 6 volts. I have our solar set up run though it and every morning as the array brings up the voltage it causes the unit to freeze at a blank screen. If it starts at 6 volts no problem but ramping up from 0 volts to 6 volts cause the issue.No problem I thought, I will use the external power input...however this has its own caveat. The power input on the side is NOT isolated. When you use the external power port on the side it bleeds a small amount of voltage (~.03v) into the system it's analyzing. It took a lot of trial and error w/ power supplies to get it down to such a small amount. It seems it really needs to be as exact as possible to the power requirements of the analyzer to minimize the amount of voltage it bleeds. This is annoying as it can cause some solar charge controller to think the solar panels are putting out slight power at night, which can cause its own set of issues. Lucky for me my charge controller ignores this slight amount of electricity, so all is well.The other annoying thing about it is the display cycles so fast it's hard to read. I usually need it to cycle a few times before I can read everything. Overall I would rate this as a solid buy. 4Unit I recieved was non functional This is my second review the first was rejected by Amazon I guess for being too honest. Product was completely dead out of the box 1Works great. Couple minor drawbacks, but very happy with it. It works GREAT, but there are a couple drawbacks:1. The memory is not persistent, so once you disconnect your battery you lose your readings. This may not matter for some people, but it makes it tough to use for long term monitoring (like in the battery bag of an electric bike to see whether it is time to recharge, if you don't recharge daily).2. The wires that are attached are only 12 gauge... there's no way you can pull 150 amps through 12 gauge wires without lighting something on fire. This should really be called a ~50amp meter with those wires. I'm probably going to have to disassemble it to see if I can attach my heavy gauge wires directly to whatever it is using for a shunt. For reference, I bought this to measure a 48v60a load that is wired using short runs of 4 gauge wire, which would be severely bottlenecked if I tried to run it through this meter.Here is a good tip- if you need to measure voltage below the operating voltage, like for example a large single cell LiFePO4 battery, the pins on the source side accept a BEC connector. I just grabbed a small battery I had lying around and plugged the BEC connector into that port and it worked! Not sure why there are three pins but it works fine with just two.UPDATE: I opened the meter up and confirmed that the wires are easily replaced. Firstly, the red wire (positive), is only a pass-through wire, so you don't need to hook up the positive output through the meter- you can just hook the red wire to positive source and leave the "load" side red wire disconnected. Secondly, the solder pads on the negative leads are quite large and would definitely fit a thicker wire, so I desoldered the 12 gauge and added a thicker wire. Now I can measure the full load that I sought to measure (a 5000w 48volt load). 4Works well for me I use this to monitor my rc airplane power. It works well, easy to read and seems to be accurate. The wires are difficult to solder ends onto. 5I like this little guy I like this little guy. Nifty and inexpensive. I put some Anderson Powerpoles on it, use it between battery and load, and between charger and battery to keep an eye on things. I don't even necessarily know what I needed all the information for, but it's been nice when using it with a portable radio to check the amp draw. 4Very Poor Quality The leads are terribly short. I found it impossible to get PowerPole leads on it. In addition, someone mentioned theirs was 12ga wiring. Mine was 8ga with such poor insulation value. I was able to strip of the insulation with my fingernails. The insulation doesn't adhere to the wiring. Very poor product, consider something else. 1Pretty accurate Picked this up to calibrate my current sensor on my quadcopter. I used the amp readings from the GT Power watt meter to calibrate my power & battery settings in Betaflight. I then took a fresh battery and ran my quad on the bench until I got a voltage warning from my flight controller and noted the putative mAh used (374). I then recharged the battery and noted the mAh reading at the end of the charge: 370. Not too shabby!Search around on youtube and you'll find a really helpful review where the guy uses a calibrated bench power supply to test this unit. 5Nice affordable meter, great for portable use There are other versions of this same unit sold for several times the price. The only difference seems to be that those have connectors soldered on them. It was easy to open it up, remove the existing cable and replace it with my own longer cables where I soldered on powerpole connectors.I have tested this unit with my DX power supply and with my LiFePo4 battery and it worked great with both.The small size and weight of the meter make it very suitable for portable operation in the field. 5Does not work the way its suppose to !!!! Looks like mine is faulty!! Shows only voltage !?? No amperage under load and of course no wattage !!!I bought it to monitor my e bike battery pack ! ITS USELESSGoing back 1Great, except for dim display Works very well, only drawback is display not readable in anything like day light. Combine with a lamp or two, and one can load test a rather large battery. I was able salvage same and avoid the purchase of a $300 aircraft battery. Also, the timer function does not appear, even when drawing 2-3 amps. 4
