Specs only, not hands-on tested. This page is planning arithmetic plus manufacturer specs (BLUETTI US product pages checked 2026-10-09; other brands’ figures from our earlier comparisons, linked). We have not run a fridge or router through an outage on any of these stations. Every load below is an example input, so swap in the numbers from your own EnergyGuide label and router adapter. Results vary.

The short answer

For an example top-freezer fridge + router/modem, the planning target is roughly:

• Overnight (8–12 h): a ~1 kWh station covers it on paper.
• A full 24 h: about 1,750 Wh with margin, which points to the 2 kWh class.
• Wi-Fi only: even a ~300 Wh station gets you through an evening, and a ~1 kWh station runs a router for more than a day on paper.

The rest of this page shows the math so you can redo it with your own numbers.

Step 1: The fridge’s daily Wh (use the label, not the running watts)

Fridges cycle on and off, so “running watts” overstates the average draw. Use your EnergyGuide kWh/year: Wh/day ≈ kWh/year × 1,000 ÷ 365. Our fridge 24-hour guide uses ENERGY STAR category medians (via the Fridge.com Energy Index):

We use the top-freezer median (991 Wh/day) below. Your model’s label beats any median.

Step 2: Add Wi-Fi (router + modem)

A router plus modem typically draws about 10–20 W combined (check the adapter labels). We use 15 W, or 360 Wh/day. One honest caveat: a power station keeps your equipment on, but your internet provider’s network also needs power in your area. If their gear is down, your router has nothing to connect to.

Step 3: Multiply by outage length and add margin

Fridge (991 Wh/day) + router (15 W), with this site’s default 1.3× margin for inverter losses and not draining to 0%:

Same numbers as the fridge guide. Plug your own loads into the Watt-Hour Calculator for a custom band.

Step 4: Check surge, not just Wh

A compressor can briefly pull several times its running watts when it starts. If the station’s inverter can’t handle that start-up spike, capacity doesn’t matter. Compare the station’s rated AC output and surge with your fridge (a plug-in meter reading is better than a guess). Note that BLUETTI’s Power Lifting mode is for heating-type (resistive) loads, and BLUETTI says not to use the AC180’s version for air conditioners or washing machines. It is not extra capacity for compressors.

How long common stations last on this example load (planning math)

Fridge + router averages ≈56 W (1,351 Wh ÷ 24 h). Hours ≈ capacity ÷ 1.3 ÷ 56 W:

*AC180 UPS figure is from the comparison table on BLUETTI’s Elite 100 V2 page. These hours are arithmetic, not measured runtimes. A hot kitchen, frequent door openings, or an older fridge can push real use well above the label.

Wi-Fi only: the station’s own draw matters

For tiny loads, the station’s own idle consumption becomes a big share of the total. BLUETTI publishes a runtime formula: capacity × 90% depth of discharge × 85% inverter efficiency ÷ (load + self-consumption). It lists about 10 W self-consumption for the Elite 100 V2 and about 15 W for the AC180. For a 15 W router:

• Elite 100 V2: 1,024 × 0.9 × 0.85 ÷ (15 + 10) ≈ 31 h
• AC180: 1,152 × 0.9 × 0.85 ÷ (15 + 15) ≈ 29 h

That’s far less than a simple “1,024 Wh ÷ 15 W” would suggest. BLUETTI notes the formula is for reference only and doesn’t fit compressor loads like fridges, which is why we use daily Wh for the fridge above.

If your router runs from a 12 V adapter, a DC cable from the station’s 12 V outlet can skip the inverter, but only use a cable your router’s maker supports. For a Wi-Fi-only kit, the BLUETTI Elite 30 V2 lists 288 Wh, 600 W AC, and ≤10 ms UPS at 9.48 lb. With our 1.3× margin that’s ≈222 Wh, or roughly 15 h of a 15 W router on paper (BLUETTI doesn’t list its self-consumption, so treat that as a ceiling). It’s not a fridge station.

UPS: why switchover time matters for the router

If the station sits between the wall and your gear in pass-through mode, it switches to battery when the grid drops. A fridge doesn’t care about a few milliseconds. Routers and modems may reboot if the gap is too long. BLUETTI lists ≤10 ms for the Elite 100 V2, within 15 ms for the Elite 200 V2, and 20 ms for the AC180. No brand guarantees a seamless switchover for any specific device, so test it on a normal day by unplugging the station from the wall. BLUETTI’s Elite 100 V2 page also lists an app setting, Power Memory Mode, to auto-resume power after outages.

Recharging during a longer outage

• Solar (rough): panel watts × full-sun-equivalent hours ÷ 1.25. With an assumed 4 sun-hours, 400 W of panels gives ≈1,280 Wh/day, roughly the 24 h fridge + router load before margin. Max solar input caps it: 1,000 W on the Elite 100 V2 and Elite 200 V2, 500 W on the AC180. Clouds and winter sun cut this hard. See solar charge-time math.
• Car: slow. BLUETTI lists ≈12–12.5 h to fill an AC180 at 100 W from a 12 V socket, and 96 W (12 V) car input for the Elite 200 V2.
• Gas generator: BLUETTI lists generator charging for the AC180 and Elite 100 V2. Run any generator outdoors only, per its maker’s carbon-monoxide guidance.

Picks by outage plan (constraints, not rankings)

1. Overnight outages, fridge + router: a ~1 kWh station. The BLUETTI Elite 100 V2 is the lighter pick (25.3 lb per BLUETTI’s FAQ) with 3,600 W surge, ≤10 ms UPS, and 1,000 W solar input. The BLUETTI AC180 has more Wh (1,152) but 2,700 W surge, 20 ms UPS, a 500 W solar cap, and 35.27–37 lb (BLUETTI publishes both).
2. A full day without power: the 2 kWh class. The BLUETTI Elite 200 V2 lists 2,073.6 Wh, 2,600 W output, 1,000 W solar, and a 6,000+ cycle rating to 80%. It weighs 53.4 lb and, per BLUETTI’s FAQ, isn’t expandable. Plain-link alternatives: EcoFlow DELTA 3 Max (2,048 Wh, <10 ms) and Jackery Explorer 2000 v2 (2,042 Wh, 39.5 lb, 400 W solar cap).
3. Another brand to compare: ALLPOWERS lists two LiFePO4 stations in these size classes. Per ALLPOWERS’ product pages (checked 2026-10-21), the R1500 is 1,152 Wh with an 1,800 W pure sine inverter (3,000 W peak), 0–80% AC charging in 45 min at up to 1,500 W, 3,500+ cycles, and 15 ms UPS; the R2500 V2 is 1,920 Wh with 2,500 W AC output (5,000 W peak), about 1.5 h for a full AC charge, and 15 ms UPS. On our example load that’s ≈15.8 h and ≈26 h on paper. Their 15 ms switchover is slower than the ≤10 ms units above, so check it against your router (see the UPS section). Browse them in the ALLPOWERS portable power station collection.
4. Multi-day outages: either plan daily recharging (solar or generator) or look at expandable systems. EcoFlow lists the DELTA 3 as expandable to 5 kWh with extra batteries; see EcoFlow vs Anker SOLIX for home backup.
5. Wi-Fi and phones only: the Elite 30 V2 class (above), or any ~1 kWh unit if you want a day or more.

Safety notes

• Battery stations produce no exhaust, but follow each manual. BLUETTI says the AC180 and Elite 100 V2 must stay upright, and that the AC180, Elite 100 V2, and Elite 200 V2 are not waterproof.
• BLUETTI lists 32–104°F as the charging range for the AC180 and Elite 100 V2. Keep the unit indoors.
• Don’t wire a portable station into your home’s panel yourself. Transfer switches are electrician territory.
• Medical devices come first. If someone in the home relies on one, size for it separately and ask the device maker and clinician. See our CPAP travel guide.

FAQ

Can a 1,000 Wh power station run a fridge for 24 hours? For the example top-freezer fridge plus a router, not with margin: the target is ≈1,756 Wh. A 1 kWh station gets about 14 hours on paper. A compact fridge alone (≈674 Wh/day × 1.3 ≈ 876 Wh) fits on paper, with little to spare.

What size power station do I need for a refrigerator during a power outage? Start from your EnergyGuide daily Wh, multiply by the hours you want to cover, and add ~30%. Then confirm the station’s surge can start the compressor.

How long will a power station run my Wi-Fi? For a 15 W router, BLUETTI’s own formula gives ≈31 h on an Elite 100 V2 and ≈29 h on an AC180. Results vary with your router’s real draw.
