Expandable power stations with 2,000 Wh or more (2026)

Each value is what the manufacturer states on the linked page. "Not stated" means the maker's page doesn't list it. Ordered by battery capacity, smallest first, then by weight.

Every unit here accepts its maker's own extra batteries, sold separately; the expansion figure is what each maker states, and the extra batteries add weight of their own. The four 2,000 Wh class units are close on capacity and AC output, so the choice between them comes down to how far you may want to expand, how much you can lift and how much solar you plan to connect. The Anker SOLIX F3000 and EcoFlow DELTA Pro 3 start much larger, at 3,072 Wh and 4,096 Wh, and weigh 91.5 lb and 113.5 lb.

• If you want the lightest unit in this list → the Anker SOLIX C2000 Gen 2 at 41.7 lb. Anker states "Up to 4kWh Expandable Capacity", the smallest expansion ceiling here, which suits doubling the battery once.
• If you want room to grow the most from a 2 kWh start → the OUPES Mega 2 Pro ("Expansion Capacity Up to 10.24kWh with 4 B2") or the BLUETTI AC200L ("expandable capacity up to 8,192Wh"). BLUETTI does not state the AC200L's weight in text we could read, so check it on the maker's page.
• If you plan a large solar array → the Anker SOLIX F3000 (Anker states "Up to 2,400W Solar Input") or the EcoFlow DELTA Pro 3 (2,600 W total across two ports). Among the 2 kWh units, the BLUETTI AC200L lists 1,200 W and the OUPES Mega 2 Pro and EcoFlow DELTA 2 Max 1,000 W.
• If you need the most continuous AC output → the EcoFlow DELTA Pro 3 (EcoFlow states "AC Continuous Output 4000W") or the Anker SOLIX F3000 (3,600 W in total across its outlets).
• If the unit will mostly stay in one place → weight matters less; compare capacity and expansion. Above about 90 lb, plan how you will move the unit before you buy it.

A rough runtime check: divide the capacity by the watts you will draw. With 2,048 Wh, a 150 W load runs at most about 14 hours by that division; with 4,096 Wh, at most about 27 hours. Converting battery power to AC uses some energy, so expect less, and remember that each extra battery adds its own stated capacity.

• What each extra battery adds. Makers state expansion as a total ("up to 10.24kWh with 4 B2") or per unit; count how many extra batteries that takes and plan the space and weight for them.
• Solar input and voltage. A larger battery takes longer to recharge from panels, so the stated solar input matters more here than on a small unit. Match the panels to the voltage range on the maker's spec sheet.
• Outlets. Check that the outlet types you need are on the unit; the maker's spec sheet lists each one with its rating.

8 of the 29 portable power stations we catalogued (as of October 27, 2026) have 2,000 Wh or more and are expandable according to their makers. We picked six: the four 2,048 Wh units and two of the four larger ones, the Anker SOLIX F3000 and the EcoFlow DELTA Pro 3. The other two, the Goal Zero Yeti PRO 4000 and the Jackery Explorer 5000 Plus (3,994 to 5,040 Wh), appear in the finder. Four more units with 2,000 Wh or more are not on this list because their makers don't state expansion for them or state that they can't be expanded. We list each power station without solar panels or extra batteries; bundles are separate products.
