Review: awesome device - 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.
Review: Versatile load that I should have purchased long ago. Not user friendly but does all I've needed. - I've used this load to check old VRLA UPS batteries and USB 12W power adapters, so far. I had 6, 9AH VRLA batteries, from 2 UPS units. It was nice to know that the old batteries had <20% of their rated capacity left. Only one of the USB adapters, met the 12W spec. These tests were simple to perform with this electronic load. I like that it powered up with a QR code to help you get the manual. I don't like that I see it each time I power it up. I tool away 1 star because it isn't that user friendly. I would like to be able to reset the data without going into setup and scrolling. I also don't like the fact that the fan seems to stop running as soon as you turn off the load. I've been dialing down the current or constant power setting, before turning off the load, to cool things down a bit.

## Features

- 4 operating modes: CC-constant current operation; CV-constant voltage operation; CW-constant power operation; CR-constant resistance operation. There are three intelligent safety protections in the discharge detection process, which can monitor the discharge tube status in real time, which is safe and reliable. An external wired NTC thermometer can realize dual temperature measurement inside and outside.
- 2.4-inch high-definition large color screen blue digital curve version of high-power electronic tube digital load meter. Intelligent temperature control color glare fan, high power, long life, durable cooling fan; 180W high power / 200V wide voltage / 20A high current, strong performance.
- Support testing Android, Type-C cable, Mini and other wires, and display a variety of test data on one screen. By checking and killing, by testing various data cable/charger test/discharge aging/DC power adapter current, voltage, power and other parameters, the operation is simple and the test is convenient and fast.
- 180W load discharge aging test, using intelligent temperature control light effect fan design, built-in large discharge tube, the temperature is maintained at about 50~80 degrees; easily test the voltage, current, capacity and other data of various power sources such as lithium batteries/USB chargers; Powerful, safe and reliable.
- If there is any abnormality in the product, whether it is return or exchange, you can contact us first, we will reply you within 6 hours, we will be happy to solve it for you, thank you.
