Large expandable power stations compared: DELTA Pro 3 vs Anker F3800 vs Explorer 3000 Pro
This is the heavy class: 3–4kWh base units that expand toward whole-home territory, run 240V appliances, and weigh as much as a person. Two of the three are current flagships. The third — Jackery’s Explorer 3000 Pro — is discontinued new in the US and survives only as refurbished stock, which is exactly why it’s in this comparison: people keep finding it refurbished and asking whether it’s worth it.
All specs below are manufacturer specifications checked 2026-10-15 against the product records. Prices are manufacturer direct-to-consumer, checked the same date. We have not hands-on tested any of these units.
Safety boundary first: units this size can backfeed a home panel if misused. Anything involving transfer switches, panel interlocks, or whole-home wiring belongs to a licensed electrician and the manufacturer’s instructions — we don’t cover installation, and neither should a buying guide.

The two current flagships
The F3800’s headline is 240V from a single unit. 6,000W continuous with 120V/240V dual-voltage output means it can run a well pump, a central AC component, or an electric dryer circuit that the others can’t touch without pairing units. At $2,199.99 it’s also $600 cheaper than the DELTA Pro 3 — $0.57/Wh, the best capacity-per-dollar in this class.
The DELTA Pro 3 answers with capacity and solar. 4,096Wh base (expandable further), 2,600W solar input — the most of any unit here — and 50-minute 0–80% AC recharging. If your plan leans on daytime solar harvest during multi-day outages, the DELTA Pro 3 refills fastest. You’re paying $600 more for that edge.
The refurbished question: Explorer 3000 Pro
At $2,499 refurbished, the 3000 Pro costs more than the brand-new F3800 ($2,199.99) while offering less in every column that matters: 3,024Wh vs. 3,840Wh, 3,000W vs. 6,000W output, NMC vs. LiFePO4 chemistry, 6-month refurb warranty vs. 5 years, no 240V. Its one advantage is weight (63.9 lbs — actually movable by one strong person).
The math doesn’t favor it at $2,499. It would need to be meaningfully under $2,000 refurbished to compete with the F3800 on value. This is a “buy it only if you find a deep clearance” unit, not a “buy it at the current refurb price” unit.
The verdict (reasoning disclosed)
- Best buy right now: Anker SOLIX F3800 at $2,199.99. Cheapest per Wh, 240V dual-voltage, LiFePO4, 5-year warranty, in stock new.
- Best for solar-heavy plans: EcoFlow DELTA Pro 3 at $2,799. The 2,600W solar input and 50-minute AC top-up justify the premium if you’ll recharge primarily from panels.
- Explorer 3000 Pro: only on deep clearance. At $2,499 refurbished it’s outclassed by the F3800 at every level.
A note on weight: the F3800 is 132 lbs and the DELTA Pro 3 is 113 lbs. These are stationary units — plan their location once, preferably near where they’ll charge.
