Review on Intelligent USB Port Display PWM 50A Solar Charge Controller for 12V/24V Auto Charging Regulation by Lucas Salgado

I installed a 100 watt solar panel on my trailer and bought it to regulate my battery charge. I would like the battery not to be charged and I would also like to know: 1. Battery status. 2. current entering the battery and 3. current leaving the battery. This simple charge controller handles all of these tasks with ease at a very affordable price. It's easy to connect and easy to use. I like USB ports because I have radios, flashlights, and flashlights that use AA batteries, and I have several USB chargers that use AA batteries. The first charge controller I had showed that the current drawn from my battery was 0.4 amps all the time. Even with no load and NO wires connected to the battery. Also, the USB port was able to charge my phone but the AA battery charger didn't work. The sellers sent me a second one and it kept showing my battery drain as 0.3 amps. I found with the VOM that each actual draw was 0.3 amps higher. Instead of trying to have a third, I decided to just live with it. I just subtracted 0.3 amps from what I saw on the display. After about a week of use the 0.3 amp phantom load was gone and now it works great. Let's see how long it works.
