Best Power Station for Home Backup: 7 Ranked by Real Math
Seven power stations ranked for home backup by usable watt-hours per dollar — with the fridge-CPAP-router runtime math shown for every pick.

- Editor's Choice1
Jackery Explorer 1000 v2
The best first backup battery. At its current $499 sale price you get 1,070Wh (≈910Wh usable) for the least money in the 1kWh class, in the lightest box here (23.8 lb) — about 12 hours of fridge + CPAP + router by our load math.
- 2
Bluetti Elite 200 v2
The best capacity math on this list: $899 for 2,073.6Wh ($0.43/Wh) with a 6,000-cycle LiFePO4 pack — double everyone else's rated lifespan except nobody's — and 2,600W of output. Roughly 23 hours of the fridge-CPAP-router load.
- 3
EcoFlow Delta 3 Plus
The one to buy as a UPS: under-10ms switchover, a 56-minute full recharge, six AC outlets, and expansion up to 5kWh later. You pay for it — $689 for 1,024Wh is the weakest $/Wh in the 1kWh class here.
- 4
Jackery Explorer 2000 Plus
The expansion path: $899 for 2,042.8Wh now, up to 12kWh with battery packs (24kWh paired) later, and 3,000W handles almost any single appliance. At 61.5 lb it has wheels for a reason.
- 5
Anker SOLIX C1000 Gen 2
The most AC output per dollar in the 1kWh class: 2,000W continuous from a $549.99 box that recharges in 49 minutes. No expansion port and only 600W of solar input — this is the grab-and-go pick, not the build-on-it pick.
- 6
EcoFlow Delta Pro 3
The whole-house tier: 4,096Wh, 4,000W, and real 120/240V output for a well pump or mini-split — about 45 hours of the fridge-CPAP-router trio. $2,399 on sale; past this point you're shopping transfer switches, not power stations.
- 7
Bluetti AC180
The budget capacity play: $499 buys 1,152Wh — the most watt-hours per dollar under $500 — and 1,800W of output. It concedes weight (35.3 lb) and cycle life (3,500 to 80%) to the Jackery at the same price.
Every ranking on this page comes from three numbers: what a unit costs today on its manufacturer's own store, how many of its watt-hours you can actually use, and how long that keeps a real outage load alive. No lab, no vibes — the receipts are in the source ledger at the bottom, every one checked on July 21, 2026.
The ranked math, in one table
The load we size against is the one Texans actually run during an outage: a full-size refrigerator (120W, compressor duty ~35%), a CPAP without its humidifier (60W, ~1/3 of the day), and a router + modem (15W, always on). That averages about 77W. "Usable Wh" applies an 85% inverter-efficiency haircut to the rated capacity — spec sheets quote the battery, you live off the inverter.
| Unit | Price today | Rated / usable Wh | $ / rated Wh | AC output | Fridge+CPAP+router |
|---|---|---|---|---|---|
| Jackery Explorer 1000 v2 | $499 (list $799) | 1,070 / ~910 | $0.47 | 1,500W | ~12 h |
| Bluetti Elite 200 v2 | $899 | 2,073.6 / ~1,760 | $0.43 | 2,600W | ~23 h |
| EcoFlow Delta 3 Plus | $689 (list $799) | 1,024 / ~870 | $0.67 | 1,800W | ~11 h |
| Jackery Explorer 2000 Plus | $899 (list $2,199) | 2,042.8 / ~1,736 | $0.44 | 3,000W | ~22 h |
| Anker SOLIX C1000 Gen 2 | $549.99 | 1,024 / ~870 | $0.54 | 2,000W | ~11 h |
| EcoFlow Delta Pro 3 | $2,399 (list $3,699) | 4,096 / ~3,480 | $0.59 | 4,000W (240V) | ~45 h |
| Bluetti AC180 | $499 | 1,152 / ~980 | $0.43 | 1,800W | ~13 h |
Runtime figures are computed from manufacturer capacity specs and typical appliance draws — they are estimates, deliberately conservative, and the formula is on our methodology page so you can rerun any of them yourself.
Power station or solar generator? Same box.
If you've been searching both terms: a solar generator is a portable power station photographed next to solar panels. There is no mechanical difference — every unit above is a battery with an inverter that will happily charge from a wall, a car socket, or panels. What matters for storm prep is the solar input ceiling: the Delta 3 Plus accepts 1,000W of panel input while the Explorer 1000 v2 tops out at 400W, which is the difference between refilling in an afternoon and refilling in two sunny days.
What the July sale prices do to the math
Two of these rankings are sale-dependent, and it's worth being honest about it. The Explorer 1000 v2 at $499 is the cheapest real kilowatt-hour on the market right now; at its $799 list price it drops to $0.75/Wh and the Bluetti AC180 takes the value crown in this class. Same story for the Explorer 2000 Plus — $899 against a $2,199 list is the sale doing the work. The Bluetti and Anker prices are their everyday numbers. If you're reading this after the sale window, check the ledger dates below and do the division again — the formula doesn't change, the inputs do.
How much capacity do you actually need?
The honest sizing rule for a Texas outage: take your average load in watts, multiply by the hours you want to survive, then divide by 0.85. The fridge-CPAP-router trio at 77W for 24 hours needs about 2,170Wh usable — which is exactly why the 2kWh class exists, and why the 1kWh class is a 12-hour bridge, not a two-day plan. A window AC unit or space heater roughly septuples the load; that's 240V-tier territory, not a $500 purchase.
If your load list is different from ours, the division works the same — a full appliance-by-appliance calculator guide is next on our publishing schedule.
Frequently asked
- What's the difference between a power station and a solar generator?
- Nothing, mechanically. A 'solar generator' is a portable power station marketed together with solar panels — same battery, same inverter. Every unit on this list accepts solar input; whether you buy panels is a separate decision.
- What size power station will run a refrigerator?
- A full-size fridge draws about 120W while the compressor runs, and the compressor runs roughly a third of the time — call it 42Wh per hour, plus inverter losses. A 1kWh-class unit with ~900 usable watt-hours runs a fridge alone for about 20 hours; add a CPAP and a router and you're closer to 12.
- Can a power station back up a whole house?
- Not the 1–2kWh class. Whole-house backup needs 240V output and serious capacity — on this list only the EcoFlow Delta Pro 3 plays in that tier, and a true whole-house setup adds a transfer switch and usually expansion batteries.
- Are these prices sale prices?
- Some are. Every price here was checked on the manufacturer's own store on July 21, 2026, during a mid-July sale window, and the list price is noted where a unit is discounted. The rankings note where sale pricing changes the math.
