BLUETTI sent us the Elite 300 to test, and we’ve now had it long enough to say something more useful than “it’s nice.” It’s lived between the seats of the truck, sat on a dusty workshop floor, and been dragged out every time the mains let us down. So instead of an unboxing, here’s the honest version: what it actually did for us over a few weeks of moving into a new workshop, and where the specs matter once you’re leaning on it for real.
If you’d rather watch, the Elite 300 got its moment in our Euro Auctions episode — jump straight to the video.
This is a sponsored, honest review. BLUETTI gave us the unit and the links below are affiliate links, but the opinions are ours.
Our first proper test wasn’t planned as a test at all. The truck — an old Iveco — doesn’t have air conditioning, and we had a long drive up the country to Euro Auctions in the middle of a British heatwave. So we did the only sensible thing and built our own aircon out of a cool box, some ice, a few pipes and an extractor fan. Bodged, ridiculous, and it worked.
The whole contraption ran off the Elite 300 sat between the seats. Five hours of blowing cold air later, we glanced at the screen expecting it to be gasping. It was still showing 89% — and a day and a half of runtime left at that draw.
The reason it can do that without being a two-man lift is the headline trick: it holds 3,014Wh in a box that’s 366 × 305 × 297.5mm and weighs just 26.3kg. BLUETTI calls it the world’s smallest 3kWh portable power station, and it’s a Frost & Sullivan-certified claim — up to around 21% lighter and nearly 59% less volume than other 3kWh units.
Then it earned its keep properly. Our new workshop has very few usable sockets, and half our renovations jobs involved killing the power totally. The Elite 300 became the socket we carried around with us.
Over a few weeks we’ve run filming lights, a couple floor cleaners, the power washer, a paint sprayer and the fridge off it — and no drama with any of them. That’s the 2,400W rated output doing the work, which covers most of what a normal house throws at a plug: a kettle, a hairdryer, a hob ring, a microwave. When something spikes harder than that on start-up, Power Lifting mode pushes it to 4,800W to catch the surge rather than tripping out.
We even used it to bring a machine back to life. One of our auction finds was an old electric mast lift with dead 12V batteries hidden under the flaps. We put it on charge straight off the Elite 300 to see if it’d wake up. It did.
On paper it’s a list. In use, it’s the difference between plugging straight in and hunting for an adapter. You get 2 AC outlets, 2 USB-A, 2 USB-C (one 100W, one 140W — enough to fast-charge a laptop), a cigarette-lighter socket, and a 12V/30A DC port.
That 12V port is the one caravan and van people should care about. It’s built for the onboard stuff — water pumps, lights, diesel heaters, a car fridge — the loads that are a faff to run through an inverter and a plug. For us it means the same battery that powers a paint sprayer indoors can run camping gear in the field without a rethink.
A big battery is only as good as how fast you can fill it again. This is where the Elite 300 shows off.
Under the lid it’s LiFePO₄ cells rated for 6,000+ cycles. If you charged it every single day it’d be years before you noticed the capacity drop. This isn’t a battery you replace next season.
At home it doubles as an uninterruptible power supply. If your mains drops, it switches over to battery in 10 milliseconds — fast enough that a router, a fish tank filter, a computer mid-save or a fridge full of food never knows anything happened. Plug the essentials through it and a power cut becomes a non-event.
The whole lot runs through the BLUETTI app over Wi-Fi and Bluetooth. That’s where we watched the aircon barely dent the battery, and it’s more than a gauge — there’s a Timer Switch so you can schedule things to wake and sleep. Program a heater to warm a room before you’re home, remotely wake the unit from anywhere, or just check what’s left without getting off the sofa. That’s the readout that turned “I hope this lasts” into “I know exactly how long this lasts.”
For us it’s stopped being the sponsor’s box in the corner and become the tool we grab first. It’s small enough to actually move, big enough to run a real workload, fast to recharge, and well thought out with the app and the backup. If you’re kitting out a van, running a workshop that’s short on sockets, or you just want a power cut to stop mattering, it’s a lot of capability in a box you can carry.

BLUETTI didn’t just sort us out — they gave us a second unit to give away. It’s the Elite 30 V2, the pocket-of-the-boot little sibling: 288Wh, just 4.3kg, with a 600W output (1,500W on Power Lifting), 140W USB-C fast charging and the same 10ms UPS switchover. Perfect first power station for camping, picnics, road trips or the odd blackout — and the kind of thing that lasts long enough to become your second and third.
It’s a brand new, sealed unit (retail value £239) in a choice of three colours, completely free to enter, UK only, over-18s.
