Fast easy charging

I was skeptical when I made the purchase, Now.. I'm impressed. I played with it a bit connecting it to a new battery to top it off which it did in about 30min. Another battery 970cca that had been drained to 12.1v and it topped it off to 13.2v in about 2.75 hrs. The other day had it connected to a 12AH DS battery and we got snow. After accumulating about an inch of snow on the panel it was still charging, certainly at a reduced rate but charging. On a bright day I put the panel out of direct sunlight and it still topped off the battery after several hours. It definitely performs better than I would have expected. It seems the panel and charge controller it is packaged with are a good match.

It is very easy to work with, basically plug and play. It is pretty compact and the indicators are simple and easy to read. A good buy in my opinion.

I have 2 of these. 1 has 2 B300 batteries and lasts about 4 hours running a portable A/C unit. The one with the pair of B300K batteries doesn't last as long, but for a TV and a fan, it'll last for several hours. I'm thinking of plugging my fridge into it and using the generator to charge it during the next outage.

This thing is heavy (the batteries are the bulk). I have to make 3 trips to load it.

It charges fast off wall power. Solar is slower. I haven't tried charging off of the truck.

Catch these on sale. Buy an extra B300K or 3. B300 is no longer made. Bluetti runs a lot of sales. I'm probably going to get 4 more B300Ks to max out both units.

heaver built than expected

Very well made and just what I wanted
