BLUETTI B80 Expansion Battery | 806Wh

These are a good way of storing additional energy in case you unexpectedly run short using smaller Portable Power Stations. I now have five, two sets of two permanently attached to two AC60, to extend them to 2000wh of stored power each; and one to use with either an Elite 30 or Elite 100 should the devices attached to these need running for longer when there is limited sunlight for charging. I think they are a good size and weight, so much easier to move around than higher capacity batteries or larger portable power stations. Sometimes you don't need large instantaneous amounts of power, but smaller amounts over longer periods with ease of portability, and this is where these batteries used with smaller power stations excel. I like the fact that they are Automobile/mains/PV chargeable as stand alone units or can be charged via an AC60. I would recommend, like with all products, from all manufacturers, that you download, then fully read the owners manual prior to purchase, so that you are aware of possible additional purchases to get the most out of the B80 for how you may choose to use it. I hope the fact I have bought five and am likely to buy further units is an indication as to the merits of these batteries.

Greta to have extra power for the AC60 and also can be used on other power banks in power bank mode.

Used to back up an EB55 on camping trip. Excellent piece of kit

Very very good 👍 can be a buster for Bluetti AC60 and other solar generators . Very well made.I got 2 there that good 😊.

Great addition to my small generator giving extra capacity and storage. Works well simple to connect with adaptor. Well recommend

Very very good for all back up and camping .👍😁

It is the perfect addition to my EB55 more than doubling the usage time thanks Bluetti

Well I took the plunge and got the B80 to top up my EB55 and wow it's fantastic it just sits there topping up the 55 and it just seems to go on for ages I can't wait till I can top them both up with the PV200 in the summer, let the toasties flow. Great addition to my EB55 and if I can afford one then AC180 which I'd love.

I’ve always thought my EB3A was a brilliant little piece of kit, but regretted the fact that it couldn’t store a full days worth of input from my camper solar panel on the roof, which seemed a wasted opportunity.
Now that Bluetti have made it possible to add the B80 (albeit not in a perfect manner) I have enough storage capacity to leave my solar panel plugged in even when driving between stops.
I’ll add another review when I’ve tried a year with it.

Woks well a great addition
