180W DC Electronic Load Tester, USB Load Tester, Lithium Battery Capacity Tester, Color Screen Data Monitoring, Constant Current and Constant Voltage, etc. 4 Working Modes

Wow you can really do a lot with this. I use it to capacity test my RC batteries. You can even use it to destroy old worn-out ones. Just set it to 1.5a to 2a discharge to .7v, throw the battery in a fireproof bag and let it go. I also use it to stress test my USBC adapters to make sure they put out the power they are rated for. Also, if you watch a few YouTube videos it's possible to modify it to handle 450W and it's a pretty simple operation. It's easy to operate, functions very well, the screen is nice but some of the information is hard to read as the font is really small or dark in color.

Many ways to use, very good quality

Sure you could build this yourself but this is easier. Great for batter capacity testing assuming it’s a small battery. Handy!

I got this DL24-180 Watt load to replace a similar 150 Watt load which intermittently stopped seeing the input voltage when using a USB C cable.My use is mainly for testing capacities of power banks, but it can be used for testing a much wider range of power source devices.Low and behold after using the new electronic load a few times, just like the old one, it started not detecting the input voltage intermittently. There seemed to be no pattern to this and it happened with 6 different USB C cables that I have.After more experimenting I believe that I located the issue. It seems that the input voltage is not detected only when I plug the USB C cable into the small adapter board connected to the 4 terminal strip a certain way. If I flip the connector the voltage is detected. USC C is supposed to work regardless of the way the connector is plugged in. Currently I have no way to see if the USB C connector is mounted on the small board using both sets of contacts or only 1 set, or if the connection opened after repeated USB C cable insertions. Wiggling the connector does not show any changeI went back to the older 150 Watt load and I found the same situation.In my eyes this is a major flaw, hence the 1 star rating.

Works well and use it often, all it needs is a mount of some kind.

Essential bit of kit, I use it every day to load test my Lion batteries

This load tester works well when the included power supply is operating correctly. This is my second try with this product. The first one would not complete the boot cycle and constantly beep, black out the screen, show logo, beep and black out again. I found it to be the included power supply dropping voltage. The second unit booted just fine and allowed some load testing, but the same thing happened with the power supply, after a few hours the voltage dipped, unit reset and invalidated test results. It looks like this is more than capable of dissipating 180 watts as claimed, but the power supply that comes with it is lacking. It seems to hold steady with a medical grade power supply, but the only option to remedy the issue is a return per Amazon.

unit works great but the apps need a lot of work. a lot of work. very happy with the unit
