Product by product
Pros and cons
Anker SOLIX C2000 Gen 2 Portable Power Station
The 2 kWh station to pick if you will actually move it: lighter than every rival here, with an RV outlet built in. Heavy solar users should look at the BLUETTI AC200L or Jackery Explorer 2000 Plus.
Pros
- 41.7 lb: the lightest 2 kWh station we cover, by about 8 lb
- TT-30R outlet plugs straight into an RV's 30 A inlet
- Two 140 W USB-C ports
- Expands to about 4 kWh with one add-on battery
Cons
- 800 W of solar input is the lowest in the 2 kWh group
- Expansion stops at one extra battery, where Jackery's Explorer 2000 Plus reaches 12 kWh
- Anker's regional pages disagree on whether 4,000 cycles is to 80% or 70% capacity
EcoFlow DELTA 2 Max Portable Power Station
A strong all-rounder at 2 kWh: plenty of outlets, fast charging and real room to grow. The weight is the price you pay.
Pros
- Six AC outlets and 2,400 W of continuous output
- Accepts up to 1,000 W of solar, which EcoFlow says can refill it in as little as 2.3 hours
- Expands to 6,144 Wh with two extra batteries
- LiFePO4 cells rated for 3,000+ cycles, with a 5-year warranty
Cons
- At 50 lb it is a two-hand lift, not something to carry far
- Expansion works only with EcoFlow's own DELTA 2 Max Smart Extra Batteries
- We could not find a backup switchover time in EcoFlow's published specifications
Choose the Anker SOLIX C2000 Gen 2 if
- You want 2 kWh that one person can lift.

What we could not confirm
Anker's regional pages disagree on whether the C2000 Gen 2's 4,000 cycles are rated to 80% or 70% capacity.
