I purchased this charge controller because of its good reviews, and because it didn't rely on the internet or an external device to set parameters or to monitor. I needed this because I live in a remote location on an island. Unfortunately, when I connected the controller, all I could see was gibberish on the screen. It showed multiple levels at once, impossible to read. Couldn't use it at all.

I lost power for only 4 days after she blew through. I bought 2 of these, some spare batteries, a connector and a couple of base stations. With 2 panels connected in parallel I reckon I can get around 20ah's of power saved on a bright sunny day (late Oct timeframe). Enough for a hot shower and pot of coffee the next day. You know, the important things...

Not sure it is more accurate than a multimeter but is close enough to not be overly concerned. If you are doing a huge home solar panel layout I would use a multimeter but if you are checking out single panel readings then this is great. Would be excellent to check out used panels before purchase!!

Fast shipping, easy to install & works great 👍

Solar technology has come along way in the past few decades. Nowadays there are some pretty powerful and reliable solar panels that can power a number of of devices from cell phones to entire houses. This one is a small portable and foldable solar panel that can power your cell phones while out and about. Best used while camping or at outdoor evens and can be clipped onto your backpack so you don’t have to personally carry it. Recommend.

I was very skeptical at first because of the price however, it’s way more efficient than all the other solar panels that I have bought in the past. The only downside is it does not come with any stakes to stake it in the ground to prep for wind however, it puts out way more energy than I anticipated. I literally just ordered another one because the price is so great. If you’re 120 W panel is only pushing out 60 W get rid of it and buy this for sure. It’s not even that sunny today and I’m getting 90 W.
