Pros and cons
Pros
- 2,000 W continuous AC output, with 3,000 W surge, from five outlets.
- Full wall charge in 49 minutes in UltraFast mode, according to Anker.
- Up to 600 W of solar input.
- Two 140 W USB-C ports.
- LiFePO4 battery rated for 4,000 cycles, with a 5-year warranty.
Cons
- Not expandable: Anker left out an extra-battery port to save size and weight.
- The 49-minute charge needs UltraFast mode switched on in the app, and only works with the battery above 68°F.
- At 24.9 lb it's a two-handed carry.
Who it's for
Campers and anyone who wants a 1 kWh unit that can run high-draw appliances and recharge quickly between outages.
Who should skip it
Skip it if you think you'll want more capacity later. Expandable units like the EcoFlow DELTA 3 Plus can add batteries; this one can't.
