Our verdict
The mid-size pick for solar charging and USB-C devices. If weight matters more than solar input, the RIVER 2 Pro is lighter.
Pros and cons
Pros
- 500 W of solar input, more than double the RIVER 2 Pro's 220 W
- 1,000 W of AC output with a 2,000 W power-lifting mode for kettles and hair dryers
- Two 100 W USB-C ports
- LiFePO4 cells rated for 3,000+ cycles, backed by a 5-year warranty
Cons
- Only two AC outlets
- 22.5 lb, heavier than the 18.2 lb EcoFlow RIVER 2 Pro
- Power lifting runs resistive heaters at reduced power; it is not a true 2,000 W output
- BLUETTI's pages give different surge figures, so we leave surge out

Who it suits
Campers and van owners who recharge from panels: BLUETTI rates the AC70 for 500 W of solar input and a turbo wall charge to 80% in 45 minutes. Two 100 W USB-C ports cover laptops and cameras, and the 1,000 W inverter runs most small appliances.
Compare it with the EcoFlow RIVER 2 Pro in AC70 vs RIVER 2 Pro.
Who should skip it
Anyone who needs to run several AC devices at once (there are two outlets) or a microwave above 1,000 W. Power lifting is meant for resistive loads such as kettles, which run at reduced power. A 1 kWh station such as the EcoFlow DELTA 3 Plus has more outlets and output.
What we could not confirm
BLUETTI's pages list surge as both 2,000 W and 1,500 W, and AC input as 950 W and 850 W turbo, so the table shows only the figures its US product page states. The 1,574 Wh expansion figure comes from BLUETTI's AC70 + B80 kit listing.
Frequently asked questions
- How long does the BLUETTI AC70 take to charge?
- BLUETTI rates turbo AC charging at 0-80% in 45 minutes. With solar, it accepts up to 500 W.
- Can the AC70 run a 1,500 W kettle?
- In power-lifting mode it can run resistive heating devices up to 2,000 W at reduced power, per BLUETTI. Its regular rated output is 1,000 W.
- Does the AC70 work as a UPS?
- Yes. BLUETTI lists a 20 ms UPS switchover, which suits routers and lights; check your computer's tolerance before relying on it.
