Power Stations & Expansion

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

Rated for Europe: 230V single phase or 400V three phase, CE marking, and a maker you can get parts and service from without shipping across the Atlantic. The United States runs a separate list.

EcoFlow Europe

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

The European store ships 230V units with Schuko output and a European warranty — not a US model with an adapter. Densest hardware in the class, 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.

Bluetti

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

Stackable expansion sold through European warehouses, so a warranty claim does not cross an ocean — and the only modular topology here: AC300 and AC500 are battery-less heads, so a dead inverter does not strand your batteries.

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

The 230V versions from the European storefront, and genuinely the lightest 2kWh unit you can buy — about 17 kg, roughly half the carrying weight of the big boxes. The 2000 v2 takes XT60 solar input, so any third-party panel works.

Watch: Plastic-first construction: fine in a van, not on a job site. Single-phase 230V only, so a 400V three-phase borehole pump is out of reach. 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

6,000W from a single box with European service handling and a five-year warranty — the one unit here that carries a borehole pump or an immersion heater without a second station. Best-behaved app of the five.

Watch: At 60 kg (plus 43 kg 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.

Zendure

SolarFlow 800 / 800 Pro balcony storage

Built around the 800W balcony-feed rules that exist only in Europe: microinverter, hub and a 1.92kWh battery in one box, expandable to about 11.5kWh. TÜV Rheinland tested, and the only item on this list designed to a European rule rather than adapted to one.

Watch: It is not a portable power station — it stays bolted to the balcony and feeds the flat, so it solves a different problem from the four above. More cloud and app dependency than the rest.

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-terrace and in-vehicle appliances; rain on the vents ends the unit.
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 8 kg/kWh for the Jackery 2000 v2 against 15 for the F3800. One of these you carry; one you wheel.
230V single phase is not 400V three phase. Every station here is single phase, so a three-phase borehole pump or workshop machine needs a phase converter or a proper inverter-charger from the backup power list, not a bigger station.
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. A Pylontech or Fogstar rack behind a Victron inverter beats any portable case per kWh. If the answer is a cabin bank rather than a carry unit, the solar electrical list is where it gets built.
