EcoFlow vs Jackery vs BLUETTI: which one should you buy?

No brand wins everything, so buy the model, not the logo. EcoFlow is the pick when you want a battery that grows and switches over fast: the DELTA 3 Plus has a published <10 ms UPS, 1,000 W of solar input and expands to 5 kWh. Jackery wins on weight and simplicity: the Explorer 1000 v2 is 23.8 lb for 1,070 Wh, but its v2 models cap solar at 400 W and don't expand. BLUETTI wins on value: the AC180 is the cheapest per watt-hour here ($0.43/Wh); it was back in stock at BLUETTI on October 31, but on November 8 BLUETTI listed it out of stock (still $499, ships from December 14), and the AC200L costs the same $899 as a Jackery 2000 v2 while adding 1,200 W solar, 7,200 W surge and expansion to 8 kWh, at 62.4 lb.

What each brand does best, and where it falls short

Decision 1: budget tier and price per watt-hour

Price per watt-hour is the fairest first cut because it ignores marketing names. It is not the whole story: weight, UPS speed and solar input decide whether a cheap watt-hour is useful to you.

Surge: the figure each maker prints. EcoFlow's RIVER figures are X-Boost and BLUETTI's AC180 2,700 W is Power Lifting, both meant for heaters and kettles, not motor starts; see methodology. The Jackery 2000 Plus is sold mostly in kits on Jackery's store, so no standalone price is shown. As an Amazon Associate we earn from qualifying purchases.

Decision 2: how long the outage lasts

Runtime is nameplate Wh × 0.85 ÷ (load W + about 15 W). The 15 W is the inverter's own draw, which BLUETTI publishes for the AC180 (runtime formula) and owners have measured at about 17.5 W on a DELTA 3 Plus (owner test); the other makers don't publish it, so we use 15 W for every model. It barely matters at 300 W and matters a lot at light loads, the same method as our CPAP guide.

• Overnight blip (up to 12 hours): any 1 kWh unit covers a router and lights; buy on UPS speed and weight.
• One day with a fridge: 2 kWh. Our fridge outage guide puts a median bottom-freezer fridge at 538 kWh a year, about 61 W on average, and the compressor start needs a motor surge rating of about 1,200 W.
• Three days or more: either an expandable system (DELTA 2 Max to 6 kWh, AC200L to 8 kWh, DELTA Pro 3 to 12 kWh per unit, Jackery 2000 Plus to 12 kWh per unit) or a recharge plan from solar or a generator. Use the 3-day outage planner.

Decision 3: CPAP and UPS switchover

If the station sits on the wall charger with the CPAP plugged into it, an outage should be a non-event, but only if it switches fast enough and doesn't time out. Published switchover times:

Test it before you need it: with the CPAP running, pull the station's wall plug and make sure the machine keeps going. EcoFlow's safety instructions say to set the AC timeout to "never" for critical loads; check the same setting on any brand. Nights per machine and humidifier setting are in best power station for a CPAP and CPAP during a power outage.

Decision 4: recharging from solar

Solar input is where the brands split hardest. A day of solar harvest is roughly input watts × peak sun hours × 0.75 (heat, wiring and conversion losses, the SolarSized formula). At 4.5 peak sun hours, a typical sunny day across much of the US:

Max solar input is the maker's product-page figure, October 21, 2026. Real panels rarely hit nameplate; winter sun hours are lower, so use your state's figure on SolarSized. Jackery says it does not recommend other brands' panels on the 2000 Plus. EcoFlow notes the DELTA Pro 3's 2,600 W needs ideal conditions and panels within its voltage window.

Bottom line: if you plan to live off solar in a long outage, Jackery's v2 models are the weak link. A Jackery 2000 v2 refills only about 66% on a good day, while the AC200L and DELTA 2 Max can refill 2 kWh in a single sunny day. For panel sizing by state, see what size solar panel for a CPAP.

Decision 5: warranty, cycle ratings and where you buy

• Jackery*: 3 years standard plus 2 years extended, only for units bought from Jackery.com, Jackery-branded third-party stores or authorized dealers. Jackery's 2000 Plus FAQ tells Amazon buyers to register on Jackery's site to get the extra 2 years. Refurbished units get 6 months.
• EcoFlow: 5 years on the DELTA 3 Plus, DELTA 2 Max and RIVER 2 Pro pages. On the DELTA Pro 3 it is 3 years standard plus 2 years extended after you register in the EcoFlow app.
• BLUETTI: 5 years on the AC180 and AC200L pages.
• Cycle ratings aren't like-for-like: EcoFlow and BLUETTI rate cycles to 80% capacity, Jackery to 70%. A 4,000-cycle Jackery and a 4,000-cycle EcoFlow are not the same claim.

Decision 6: app and expandability

Expansion is the decision people regret most. A 1 kWh unit that takes an extra battery lets you start cheap and grow into multi-day backup; one that doesn't means buying a second station later. Wi-Fi matters if you want outage alerts or to check charge from work; Bluetooth-only apps work only in the same room. EcoFlow's DELTA 3 Plus app adds time-of-use and storm-warning charging, and the RIVER 3 Plus can tell a PC or NAS to shut down on low battery.
