Quick answer: Jackery is the simpler, lighter choice, and its units are heavily discounted so often that full price rarely applies. EcoFlow generally gives you more output, more solar input and faster charging for similar money, plus the option to add batteries to the DELTA 3 Plus. For most buyers who want the most capability, EcoFlow edges it. For a light, no-fuss unit bought on a good deal, Jackery is hard to beat.

Small: Jackery Explorer 300 Plus vs EcoFlow RIVER 3
| Jackery Explorer 300 Plus | EcoFlow RIVER 3 | |
|---|---|---|
| Capacity | 288Wh | 245Wh |
| AC output | 300W | 300W (600W X-Boost) |
| Weight | 3.75kg | 3.55kg |
| Max solar input | 100W | 110W |
| Wall charging | About 2 hours | About 60 minutes |
| Backup switchover | Under 20ms | Under 20ms |
| UK price guide | Around £199 | Around £199 |
Verdict: close. The Jackery holds a bit more energy. The EcoFlow charges in half the time, is slightly lighter, and its X-Boost mode lets it run some simple appliances up to 600W. For quick top-ups between trips, we’d lean EcoFlow. For a little more runtime, Jackery.
Mid-size: Jackery Explorer 1000 v2 vs EcoFlow DELTA 3 Plus
| Jackery Explorer 1000 v2 | EcoFlow DELTA 3 Plus | |
|---|---|---|
| Capacity | 1,070Wh | 1,024Wh |
| AC output | 1,500W | 1,800W (3,600W surge) |
| Weight | About 10.8kg | About 12.5kg |
| Max solar input | 2 x 100W panels listed | 1,000W |
| Wall charging | About 1.7 hours (about 1 hour in emergency mode) | Full in about 56 minutes |
| Backup switchover | 20ms or less | 10ms |
| Extra batteries | Not listed | Yes |
| UK price guide | £899 list, often heavily discounted | Around £699 |
Verdict: EcoFlow, unless the Jackery is on a big deal. The DELTA 3 Plus has 300W more output, a much bigger solar input, faster charging, a quicker 10ms switchover for power cuts and room to expand. The Jackery is about 1.7kg lighter, which matters for carrying, and is regularly discounted far below its £899 list price. At under about £500 it becomes a very good buy.
Large: Jackery Explorer 2000 v2 vs EcoFlow DELTA 3 Max
| Jackery Explorer 2000 v2 | EcoFlow DELTA 3 Max | |
|---|---|---|
| Capacity | 2,042Wh | 2,048Wh |
| AC output | 2,200W | 2,400W (4,800W surge) |
| Weight | About 17.5kg | About 20.3kg |
| Max solar input | 400W | 500W |
| Wall charging | About 103 minutes | About 68 minutes |
| Backup switchover | Under 20ms | Not stated |
| UK price guide | £1,479 | Around £1,199 |
Verdict: EcoFlow for value, Jackery for weight. The DELTA 3 Max is cheaper at the listings we checked, puts out more power, charges faster and takes more solar. The Jackery is about 3kg lighter, which helps if you’ll move it around often.

Why is Jackery’s list price so high?
Jackery’s own UK list prices are high, but its units are frequently sold for far less on Amazon and during sales. Always compare the current deal price, not the list price.
How long is Jackery’s warranty in the UK?
Three years as standard, extended to five when bought from Jackery’s website or registered there after an Amazon purchase.
Can I use Jackery solar panels with an EcoFlow?
Sometimes, with the right adapter, as long as the voltage is within the EcoFlow’s solar input range. Check both manuals first.
