EcoFlow vs Jackery vs Bluetti (and Anker)
There's no best brand, only a best model for your home. Their current 1 kWh models hold about the same energy, and testers got similar amounts out of each. The differences are sockets, price, charging speed and whether you can add a battery later. The EcoFlow DELTA 3 has four UK sockets and takes a second battery; the Bluetti costs £449, £200 less, and the Jackery was £398 at Currys, sold out there when we checked.

What each keeps going
| What's plugged in | EcoFlow DELTA 3 | Jackery Explorer 1000 v2 | Bluetti Elite 100 V2 | Anker SOLIX C1000 Gen 2 |
|---|---|---|---|---|
| Router, fibre box, 2 phones and a lamp | 16 h to 46 h | 17 h to 48 h | 16 h to 46 h | 16 h to 46 h |
| Fridge-freezer, router and 2 phones | 8.4 h to 32 h | 8.8 h to 33 h | 8.4 h to 32 h | 8.4 h to 32 h |
| Fridge-freezer, router, 2 phones, TV and 2 lamps | 6.5 h to 25 h | 6.8 h to 26 h | 6.5 h to 25 h | 6.5 h to 25 h |
Our estimates from the sizer, as a range from heavy to light use, allowing for the energy lost in the power station itself. A modern fridge-freezer uses 0.4-1.5 kWh a day depending on the model and the weather. Not lab figures; try your own list in the sizer.
Tested side by side
OutdoorGearLab ran the same tests on all four (US 120 V models). The amount of energy they got out was close: 870 Wh from the DELTA 3, 910 Wh from the Jackery and 890 Wh each from the Bluetti and the Anker, all 85-87% of the rating. The bigger gap was charging: the EcoFlow charged in under an hour, while the Jackery and the Bluetti took about two hours in their tests. Both have faster modes, set in their apps, which other testers used to charge them in about an hour.
On switchover, StorageReview timed EcoFlow's DELTA 3 Plus at just over 8 ms and The Technology Man timed the Anker at under 10 ms. EcoFlow, Bluetti and Anker all claim 10 ms or less; Jackery claims up to 20 ms, which most routers and fridges won't notice but some computers might.
What sets each apart
- EcoFlow DELTA 3: four UK sockets on the front, a five-year warranty and the only one of the four that takes an extra battery. It's the heaviest, at 12.5 kg, and testers noticed its fans. More in EcoFlow DELTA 3: which one.
- Jackery Explorer 1000 v2: the lightest at 10.8 kg and among the cheapest, with slightly more battery. Only two sockets, 1,500 W, and the slowest switchover claim. Jackery UK listed it at £899, sold out, when we checked; Currys had it for less, and Amazon sells it too. More in Jackery Explorer 1000 v2.
- Bluetti Elite 100 V2: £449 at Bluetti, with 1,800 W and the biggest solar input (1,000 W), and Bluetti UK says it has a five-year warranty. Two sockets.
- Anker SOLIX C1000 Gen 2: the most output (2,000 W) and the fastest charge, at a higher price. Anker's UK page doesn't state the socket count or the warranty for this model; The Technology Man counted four UK sockets.
What testers found
- EcoFlow DELTA 3OutdoorGearLab measured 870 Wh out, 85% of the rated capacity, and a full charge from the wall in 50 minutes, faster than EcoFlow's 56.
- EcoFlow DELTA 3OutdoorGearLab weighed it at 12.7 kg and called it "slightly larger than comparable competitors" in the 1 kWh class.
- Jackery Explorer 1000 v2TechRadar ran a 3D printer through it during an overnight power cut and the print finished without interruption, though the battery reached 0%.
- Jackery Explorer 1000 v2OutdoorGearLab measured 910 Wh out, 85% of the rated 1,070 Wh, but charging was slow at 563 Wh an hour, almost two hours for a full charge without the app's fast mode.
- Jackery Explorer 1000 v2The Solar Lab held just over 1,500 W for 10 minutes, managed a 2,200 W surge for a couple of seconds before shutting off, and charged in about 1 hour 35 minutes, or just under an hour in Emergency mode.
- Jackery Explorer 1000 v2nextpit got 902 Wh out of a full charge, measured about 47 dB in normal use and about 30 dB in the quiet charging mode, and charged it in 50 minutes in Emergency mode (an article made in cooperation with Jackery).
- Jackery Explorer 1000 v2T3 charged it from half to full in just under an hour, drawing 770-990 W, and noted the app can't turn the unit off.
- Bluetti Elite 100 V2Trusted Reviews timed a full recharge in Turbo mode at 66 minutes and measured 82.2% round-trip efficiency.
- Bluetti Elite 100 V2OutdoorGearLab measured 890 Wh out of the rated 1,024 Wh (87%), and about two hours to recharge from empty.
- Anker SOLIX C1000 Gen 2Notebookcheck got 850 Wh out (83%) at a steady 250 W load, charged it in just under 55 minutes without the fast mode, and measured about 45 dB at a metre under high load or fast charging, and much quieter at lower loads (a sample supplied by Anker).
- Anker SOLIX C1000 Gen 2The Solar Lab charged it from empty in about 47 minutes in the app's UltraFast mode, measured about 86% efficiency and an idle draw of around 13.8 W, and noted it has no working light.
- Anker SOLIX C1000 Gen 2The Technology Man ran a 1 kW heater for just over 54 minutes on 907 Wh (89%), charged it from flat in 47 minutes, and timed the switchover at under 10 ms, but it overheated after 26 minutes at 2 kW, which he said the nearby heater may have contributed to.
