Power Stations & Expansion

Portable power and the accessories that stretch it. Every link goes straight to the maker — no marketplace middlemen.

Rated for the United States: 120/240V split phase, UL listing and a dealer network you can reach. Europe runs a separate list.

EcoFlow

DELTA Pro 3, DELTA 3, River 3 & extra batteries

The densest hardware in the class: 4kWh and 4,000W with real 120/240V split-phase from one box, the fastest AC recharge here, and the highest expansion ceiling of any portable station.

Watch: Expansion is locked per generation — a DELTA Pro 3 pack will not fit a DELTA Pro, Pro Ultra or DELTA 2, so today's batteries are a dead asset the day you upgrade. The cell-to-chassis pack is the case, so it is not serviceable, and there is no aftermarket for its power semiconductors.

Bluetti

AC200L, AC300/AC500 heads, Apex 300 & B300K packs

The only modular topology on this page: AC300 and AC500 are battery-less heads, so a dead inverter does not strand your batteries and a dead pack does not strand the inverter. Cheapest expansion per kWh, and lifting mode carries motor surge.

Watch: Check the pack against the head before you buy — B300K fits Apex 300, AC500, AC300, AC200MAX and AC200L, but not the AC180, Elite 200 V2 or EB3A. The pack itself is bare: one 12W USB-A, no solar or AC input of its own.

Jackery

Explorer 2000 v2 / 3000 v2 & SolarSaga panels

Genuinely the lightest 2kWh unit you can buy — about 37 lb, roughly 18 lb per kWh, half the carrying weight of the big split-phase boxes. The 2000 v2 finally takes XT60 solar input, so any third-party panel works.

Watch: Plastic-first construction: fine in a van, not on a job site. No native 240V, so it cannot carry a well pump or a dryer at any price. Its cycle rating is quoted to 70% capacity where rivals quote 80%, and the SolarSaga panels cost well above generic ETFE per watt.

Anker SOLIX

F3800 / F3800 Plus & BP3800 expansion

The only unit under $4,000 doing 6,000W AND true 120/240V split-phase from a single box — it carries a well pump or a dryer where the others need a second unit. Five-year warranty, and the best-behaved app of the five.

Watch: At 132 lb (plus 95 lb per expansion pack) this is a wheeled appliance, not a portable. The station line is only about 18 months old, so there is no long-run warranty-claim record behind that warranty length.

Goal Zero

Yeti PRO 4000, Yeti Link & mounting kits

Vehicle-integration and mounting accessories nobody else makes, on the most rugged case here — plus the best surge behavior and the lowest idle draw of the flagships, which is what decides a long quiet outage.

Watch: You pay roughly $1,000–1,500 over equal specs for it, there is no 240V output at all, and the solar cabling is proprietary — the exact lock-in Jackery just dropped.

Beyond the brochure

What none of the spec sheets tell you

None of these are weather-rated. No flagship on this page carries a sealed-enclosure rating. They are covered-porch and in-vehicle appliances; rain on the vents ends the unit, not the warranty argument.
Cycle ratings are not comparable as printed. EcoFlow quotes 4,000 cycles to 80% of capacity; Jackery quotes 4,000 to 70%, and hits 80% at roughly 2,000. Same headline number, different finish line.
Weight per usable kWh is the portability number, and it spans two-to-one here: about 18 lb/kWh for the Jackery 2000 v2, 27 for the DELTA Pro 3, 34 for the F3800. One of these you carry; one you wheel.
Native 120/240V split-phase decides what actually runs. A well pump, a dryer or a deep-well submersible needs it. The F3800 and the DELTA Pro 3 have it from one box; the Jackery and the Yeti do not, at any price. Size it in the well pump calculator before you buy either.
Expansion batteries are proprietary to their own generation, everywhere. Every 'expandable' claim on this page means expandable with that maker's current pack, on that maker's connector, until the next model year. Budget the bank you want within one generation.
They are line-interactive, not online UPSs. Transfer is roughly 10–20ms on all of them: fine for a fridge or a router, not for gear that trips on a 15ms gap.
Past about 8kWh a rack is cheaper. Server-rack LiFePO4 with a separate inverter runs near $265/kWh against $500–700 in a portable case. If the answer is a cabin bank rather than a carry unit, the solar electrical list is where it gets built.
