I've put it through the wringer

Been using it to power our fridge, gadgets and all the rest. Having reliable power is huge for us even being part time on the road. It's ran perfectly for a the year that we've been using it.

User Friendly

I've used it several times

This battery charges quickly and has a great, simple touch interface. I tested to see how long the battery lasts and found it ran the Dometic CFX 40W Wifi Electric Cooler for about 35 hours. Good enough for a short weekend getaway.

Almost perfect!

I've put it through the wringer

We use two of these in our converted van and they power everything (lights, fan, refrigerator, and electronics). We paired them with a couple of Renogy solar panels and they work super well! One con is that we have to unplug them every night as they will beep for about ten minutes to let you know that they are no longer receiving power from the solar panels. Not the worst thing ever and they stop beeping on their own after a few minutes, just wish they didn't do that.

Large Charger

I've used it once or twice and have initial impressions

It is a cool battery that works with solar and just about anything else. Lithium battery and very useful for longer trips.
