Quick answer: model for model, Bluetti usually gives you more for your money: more output, more solar input and often a lower price. EcoFlow wins on polish: faster charging, lighter units at the 2kWh size, and the option to add extra batteries to its DELTA 3 Plus. Both use long-life LiFePO4 batteries and both offer 5-year warranties in the UK, so you can’t go far wrong with either. Pick by size below.

Small: EcoFlow RIVER 3 vs Bluetti Elite 30 V2
These are the grab-and-go units for phones, laptops, lights and routers.
| EcoFlow RIVER 3 | Bluetti Elite 30 V2 | |
|---|---|---|
| Capacity | 245Wh | 288Wh |
| AC output | 300W (600W X-Boost) | 600W (1,500W lifting mode) |
| Weight | 3.55kg | 4.3kg |
| Max solar input | 110W | 200W |
| UPS switchover | Under 20ms | 10ms or less |
| UK price guide | Around £199 | £199 to £219 |
Winner: Bluetti Elite 30 V2. For about the same money it holds a little more, puts out twice the continuous power, takes nearly twice the solar input and switches over faster in a power cut. The RIVER 3 is lighter by about three-quarters of a kilo, which matters if you’re carrying it on foot.
Mid-size: EcoFlow DELTA 3 Plus vs Bluetti Elite 100 V2
The 1kWh sweet spot, and the size most people should buy for garden offices, camping trips and short power cuts.
| EcoFlow DELTA 3 Plus | Bluetti Elite 100 V2 | |
|---|---|---|
| Capacity | 1,024Wh | 1,024Wh |
| AC output | 1,800W (3,600W surge) | 1,800W |
| Weight | 12.5kg | 11.5kg |
| Max solar input | 1,000W | 1,000W |
| Wall charging | Full in about 56 minutes | 80% in about 45 minutes |
| UPS switchover | 10ms | 10ms |
| Extra batteries | Yes, EcoFlow Smart Extra Batteries | None listed |
| UK price guide | Around £699 | £449 (RRP £599) |
Winner: it depends what you value. On specs they’re near-twins, and the Bluetti is the better value, often hundreds of pounds cheaper. The EcoFlow justifies its price if you want the option to add more battery capacity later, a quoted 3,600W surge for kit with a high start-up draw, and its confirmed four UK sockets.

Large: EcoFlow DELTA 3 Max vs Bluetti Elite 200 V2
For home backup, workshops and longer off-grid stays.
| EcoFlow DELTA 3 Max | Bluetti Elite 200 V2 | |
|---|---|---|
| Capacity | 2,048Wh | 2,073.6Wh |
| AC output | 2,400W (4,800W surge) | 2,600W (3,900W lifting mode) |
| Weight | 20.3kg | 24.2kg |
| Max solar input | 500W | 1,000W |
| Wall charging | Full in about 68 minutes | Up to 2,300W input |
| Rated cycles | Not stated | 6,000+ to 80% |
| UK price guide | Around £1,199 | Around £1,439, often discounted |
Winner: depends on how you’ll use it. The Bluetti has more continuous output, double the solar input and a rating of 6,000+ cycles, which makes it the stronger choice if you’ll lean on solar or use it daily. The EcoFlow is about 4kg lighter, charges quickly from the wall and was cheaper at the retailer listings we checked. Bluetti’s own UK prices swing a lot, and one UK review found it on sale for £999, so watch for deals.
Warranty, apps and support
- Warranty: EcoFlow’s DELTA 3 Plus is sold in the UK with a 5-year warranty, and Bluetti’s UK site lists 5 years on its Elite V2 models. Buy from the brand or an authorised UK retailer so the warranty is UK-backed.

- Batteries: both use LiFePO4 across these ranges, rated for thousands of cycles.
