Renogy 12V 20A AC-to-DC Portable Battery Charger with Alligator Clips for Lithium-iron Phosphate Batteries: Efficient Charging Solution Review

Ideal for charging Battle Born lithium batteries in our self contained camper during the winter. We use a 2000 watt generator. Very easy to use.

I ordered this charger and it worked great the first time. After that, the power would not turn on. They sent us another charger that works great. I hope it will work for a long time.

This charger lasted less than 90 minutes before bursting, hissing and smoking. The light went out just before I unplugged it, so I HOPE the internal fuse blew, but I'm very glad I was there when it happened. I would pay more money and take something else.

I'm sorry to say this as my RV's entire electrical system is Renogy based. It's bad in almost every way imaginable. I hope that one day Renogy will release an AC/shore power charger that will work with their Smart LiFePo batteries and BT hub. But the Victron 30A charger is waterproof, has bluetooth connectivity and is very smart for the same price.

Pretty good value for money. The device does not require a fan. 300 watts pulled from the wall. The specs say it's 92% efficient. Which would make it the advertised 20 amps. This is the only listed (etl) device I've found in this price range. The light is red when charging and green when finished. This thing puts out a lot of power, it's probably a little more than an old xbox360 power supply if you remember. these things.

Great product I had a 12 volt 300Ah LiFePO4 battery that was dead from driving it dead all night and I have this charger for it bought because it apparently suits the work. I disconnected the solar panels and charge controller, hooked that crap up, waited, waited, waited, then popped the green light. Reconnected everything and everything worked like clockwork. Easy to use, just plug and play.

I don't know who actually made it in China. It should have the name Renogy somewhere, but it's as simple as it gets. Time will tell if this item is well made, but I'm a little suspicious of its unknown provenance. Even the box it came in didn't have the Renogy name or logo on it. A simple error display would be nice so you don't think everything is fine when something isn't working properly.
