    • Best bang for the buck, and lots of capacity
This is perfect for our camper van, but I can use it in the house for power outages. This was the best deal during Prime day. It works great, I will get another B2 battery next Prime day. I like that the units can be separated, makes it easier to move around. Charges quickly and works for days when boondocking. A must have for camping, powers my induction cooktop, so I can use it when or where I can't have a fire or it's raining. It makes camping easy, and the large capacity lasts for days. My wife loves using her electric blanket with it too. ... show more

    • Good product
Style: Mega 1
Fab us a bit noisy, but it only runs when charging so it is not annoying. Other than that it is well-made and does what it says.

    • Good value
Style: Mega 1
I bought 3 of these to give one to each family household. Light weight, fast charging, up to 800w solar input,wireless app is a big plus. I do wish they had xt90 or xt60 connector vice Anderson but it comes with the mc4 to Anderson cable. Might be nice if it had a light and used a standard PC type power cord instead of a proprietary one. It works fine but if you misplaced it you can't just use any old cord you might have laying around. ... show more

    • Works good. Keep it charged
Style: Mega 1
Used this a few times. Works good. I let it sit for about 6 months and there was no charge left. I advise to check monthly if not in use.

Good unit but phone software for monitoring activity is absolutely useless! Won't even recognize the unit and customer service is clueless.
