Power goes out. The fridge can wait a few hours. Your sleep can’t. If you use a CPAP, a blackout isn’t just a nuisance, it’s a rough night (or several). The good news: CPAPs are one of the easiest things to keep running on a portable power station.

Step 1: Find your CPAP’s real wattage

Flip over the power brick. You’ll see an output rating (volts × amps). That’s the maximum it can draw, not what it uses all night. Real use is usually lower, and the heated humidifier and heated tube are the big energy hogs.

Your machine’s manual or manufacturer support page often lists typical power use with and without humidification. That’s the number you want.

Step 2: Do the 10-second math

Here’s the formula we use in our runtime calculator:

Nights ≈ battery Wh × 0.85 ÷ (CPAP watts × hours of sleep)

The 0.85 covers inverter losses (turning battery DC into wall-style AC). Example: a 1,024 Wh unit running a 40 W CPAP for 8 hours: 1,024 × 0.85 ÷ 320 ≈ 2.7 nights.

Estimated CPAP nights per charge

Model	Capacity	~40 W (no humidifier)	~90 W (heated humidifier)	Weight	Store price (Oct 16)
EcoFlow RIVER 3 Plus	286 Wh	~0.8 night	~0.3 night	10.4 lb	$299
EcoFlow DELTA 3	1,024 Wh	~2.7	~1.2	27.6 lb	$629
BLUETTI Elite 100 V2	1,024 Wh	~2.7	~1.2	25.3 lb	$499
Jackery Explorer 1000 v2	1,070 Wh	~2.8	~1.3	23.8 lb	$519
Anker SOLIX C1000	1,056 Wh	~2.8	~1.2	28.4 lb	$599.99

Calculated estimates with typical wattages, not measurements. Prices change often; click through for current pricing.

Our picks by situation

• “I just need one night, maybe two”: a ~1 kWh unit is the sweet spot. The Jackery Explorer 1000 v2 is the lightest here at 23.8 lb; the BLUETTI AC180 squeezes in a bit more capacity (1,152 Wh) at $499 on our check date.
• “Outages here last days”: step up to ~2 kWh, like the Anker SOLIX C2000 Gen 2 or EcoFlow DELTA 2 Max. Add solar and you can top up during the day (see our solar pairing guide).
• “Also want the fridge running”: a fridge changes everything. Read how long a power station runs a fridge first.

Sneaky ways to stretch runtime

1. Humidifier off (if your provider says that’s OK). It’s the biggest single saver.
2. Go DC. Many CPAP makers sell a DC cord. Skipping the inverter avoids the conversion losses. Use only the cord your manufacturer approves.
3. Keep the unit plugged in to the wall every night. Many units can pass power through, so you start every outage with a full battery. Some list a UPS-style switchover time (for example, EcoFlow lists <10 ms for the DELTA 3), but check whether your specific model and CPAP are a good match.
4. Charge phones elsewhere if you’re tight on capacity.

Bottom line

A CPAP is a featherweight load. A ~1 kWh LiFePO4 unit covers a couple of nights for most people, and a 2 kWh unit gives you breathing room (pun fully intended). Plug your real numbers into the runtime calculator, compare models in the spec database, or try our Blackout Survival Challenge to see how long you’d last.

Camping used to mean dead phones by day two and warm drinks by noon. Now? A battery the size of a cooler keeps the string lights glowing and the speaker playing. The trick is buying enough battery without buying something you’ll curse every time you lift it out of the trunk.

The camping trade-off: capacity vs weight

More watt-hours means more weight. LiFePO4 batteries (which all 17 models in our database use) last for thousands of cycles, but they’re not light.

Model	Capacity	Weight	AC output	Max solar	Price (Oct 16)
EcoFlow RIVER 3 Plus	286 Wh	10.4 lb	600 W	220 W	$299
Jackery Explorer 1000 v2	1,070 Wh	23.8 lb	1,500 W	400 W	$519
BLUETTI Elite 100 V2	1,024 Wh	25.3 lb	1,800 W	1,000 W	$499
EcoFlow DELTA 3	1,024 Wh	27.6 lb	1,800 W	500 W	$629
BLUETTI AC180	1,152 Wh	35.3 lb	1,800 W	500 W	$499
Anker SOLIX C2000 Gen 2	2,048 Wh	41.7 lb	2,400 W	800 W	$999.99
BLUETTI Elite 200 V2	2,073.6 Wh	53.4 lb	2,600 W	1,000 W	$899

What can you actually run at camp?

Using typical wattages (always check your device labels) and our 0.85 efficiency rule:

• Phone charge (~10 W for 3 h): trivial. Even the RIVER 3 Plus handles a whole group’s phones.
• LED string lights (~10 W): all night on anything here.
• Box fan (~60 W): about 4 hours on the RIVER 3 Plus, about 14 hours on a ~1 kWh unit.
• CPAP (~40 W): see our CPAP guide for nights per charge.
• Coffee maker (~900 W): needs a unit with more than 900 W output, so the 600 W RIVER 3 Plus is out. A ~1 kWh unit can brew a pot and barely notice.
• Electric griddle or kettle: big resistive loads. Fine for short bursts on 1,800 W+ units; they eat battery fast.

RV and van life: think “recharge,” not just “capacity”

On the road, you’re recharging daily, so solar input matters as much as battery size. A unit that takes 1,000 W of solar (BLUETTI Elite 100 V2 and Elite 200 V2, EcoFlow DELTA 3 Plus, DELTA 2 Max) can refill much faster on a sunny day than one capped at 400 W. Our solar pairing guide explains how to match panels without tripping the input limits.

Note: plugging into an RV’s power inlet is an RV-specific setup. Follow your RV and power station manuals, and get a qualified RV tech involved for anything beyond plugging in a cord.

Campsite etiquette and safety

• Batteries are silent, which your campground neighbors will love (way more than a generator; see power station vs gas generator).
• Keep it shaded and dry. Heat and rain are no friends of electronics.
• Strap it down in the car or RV so it doesn’t become a 40 lb projectile.

Bottom line

For most campers, a ~1 kWh LiFePO4 unit under 30 lb is the sweet spot. Go tiny for grab-and-go, go ~2 kWh plus solar for RVs. Plan your exact load in the runtime calculator and sort every model by weight in the spec database.

Research-based, not hands-on tested. We haven’t tested these units ourselves. Specs and prices come from each manufacturer’s US product page or user manual, checked October 16, 2026, and linked below. See our methodology.

It’s 9:47 p.m. The wind has been showing off all evening, and then click: the house goes dark, the fridge goes quiet, and the router’s little lights fade like a sad birthday cake. Somebody yells “WHO TOUCHED THE BREAKER?” Nobody did. It’s the whole street.

That’s the moment a home backup power station earns its keep. No fumes, no pull cord, no extension cord snaking out the window. Just plug in what matters and carry on.

But “best” depends on what you need to keep running. So instead of one magic answer, here are research-based picks by tier, all from published specs.

How we picked (no lab coats involved)

We didn’t test these units by hand. We compared the spec sheets in our spec database on what matters most for home backup:

1. Capacity (Wh): how long things run.
2. Continuous and surge output (W): whether your fridge or pump will start at all.
3. UPS switchover time: whether the router and PC ride through the outage without a reboot.
4. Solar input: how fast you can refill during a multi-day outage.
5. Expandability and 240 V: room to grow, and options for bigger home circuits.
6. Price per Wh on our check date.

Not sure how many watt-hours you need? Do the 10-minute sizing method first, or plug your list into the runtime calculator.

Tier 1: The essentials kit (~1 kWh)

For: Wi-Fi, phones, LED lights, a laptop, maybe a CPAP*. Apartment dwellers, short outages, “I just need to work from home tomorrow.”

Spec pick: BLUETTI Elite 100 V2

• 1,024 Wh, 1,800 W AC output, ≤10 ms UPS, 1,000 W max solar, 25.3 lb, 4,000+ cycles to 80%.
• $499 on BLUETTI’s US store on Oct 16, 2026 (BLUETTI).
• Watch for: BLUETTI publishes no surge figure for it, so it’s best for electronics and lights, not motors.

Also worth a look:

• EcoFlow DELTA 3 Plus: 1,024 Wh, 1,800 W (3,600 W surge), <10 ms UPS, 1,000 W solar, 27.6 lb, $719. EcoFlow’s store said “ships mid-November” on our check date (EcoFlow). The DELTA 3 has the same capacity and output with 500 W solar for $629 (EcoFlow).
• Jackery Explorer 1000 v2: the lightest 1 kWh-class unit in our database at about 23.8 lb (1,070 Wh, 1,500 W, 3,000 W surge, 400 W solar), $519. Jackery’s product page doesn’t list a UPS switchover time (Jackery).

Tier 2: The fridge-plus kit (~2 kWh)

For: a fridge plus the essentials for most of a day. The classic “save the groceries” setup. (Our worked example in the sizing guide uses about 2,320 Wh a day with a fridge, so a 2 kWh unit covers that list for roughly 17 hours.)

Spec pick: BLUETTI Elite 200 V2

• 2,073.6 Wh, 2,600 W, ≤15 ms UPS (per manual), 1,000 W solar, 6,000+ cycles to 80% (the longest rating we found), 53.4 lb, $899 (BLUETTI).
• Watch for: its 3,900 W figure is “Power Lifting” for resistive loads only. BLUETTI’s manual says that mode isn’t for motor or compressor loads, and we didn’t find a separate motor-surge figure. If you’re starting a fridge or pump, check with BLUETTI.

If a published surge figure matters to you (it should for motors):

• Anker SOLIX C2000 Gen 2: 2,048 Wh, 2,400 W, 4,000 W peak, 10 ms UPS, 800 W solar, 41.7 lb, $999.99 (Anker).
• Jackery Explorer 2000 v2: 2,042 Wh, 2,200 W, 4,400 W surge, <20 ms UPS, 39.5 lb, $899, but sold out on our check date (Jackery).

Tier 3: Start small, grow later (expandable 2 kWh)

For: people who want a 2 kWh unit today and the option to bolt on more battery later.

• BLUETTI AC200L: 2,048 Wh, 2,400 W, 7,200 W surge (BLUETTI’s product page), ≤20 ms UPS (user manual), 1,200 W solar, 62.4 lb, 3,000+ cycles to 80%. Expands with up to two B300 batteries to 8,192 Wh. Its outlets include a 120 V/30 A TT-30. $899 (compare-at $1,599) on Oct 16, 2026 (BLUETTI, manual PDF).
• EcoFlow DELTA 2 Max: 2,048 Wh, 2,400 W (4,800 W surge), 1,000 W solar, 50 lb. Add up to two Smart Extra Batteries for 6,144 Wh. $1,049 (list $1,299). Its spec table doesn’t list a UPS switchover time (EcoFlow).

Tier 4: The big-house kit (3–4 kWh, 240 V options)

For: longer outages, more circuits, or 240 V appliances.

• Jackery HomePower 3000 (best value on our check date): 3,072 Wh, 3,600 W (7,200 W surge), ~20 ms UPS, 1,000 W solar, 59.5 lb, $1,349, about $0.44 per Wh (Jackery). 120 V only.
• EcoFlow DELTA Pro 3: 4,096 Wh, 4,000 W at 120/240 V, 8,000 W surge, 10 ms UPS, 2,600 W solar, 113.5 lb, expandable to 12 kWh as a single unit. $2,799 (EcoFlow).
• Anker SOLIX F3800 Plus: 3,840 Wh, 6,000 W at 120/240 V, 3,200 W solar, 20 ms (grid to battery), 136.7 lb with wheels. $2,599.99 (Anker).

Budget tier: under $500-ish

• BLUETTI AC180: 1,152 Wh, 1,800 W, about $0.43 per Wh at $499, ≤20 ms UPS per its manual. The manual says to turn off Grid Enhancement mode for UPS use (BLUETTI). Its 2,700 W figure is Power Lifting for resistive loads.
• BLUETTI Elite 100 V2 and Jackery Explorer 1000 v2 (above) are $499 and $519.

The backup game plan (what to power first)

What spec sheets can’t tell you

• Real usable capacity. Expect roughly 75–80% of rated Wh at the AC outlet. Our planning rule is rated Wh × 0.8 (a judgment call based on manufacturer runtime formulas).
• Fan noise, app quality, customer service and long-term reliability. These need hands-on use or lots of owner reports. We don’t have that data, and we won’t make it up.
• Prices. They move constantly. Every price here is a brand-store price checked Oct 16, 2026. Confirm before you buy.

Research-based, not hands-on tested. We haven’t run these units on a fridge ourselves. Specs and prices come from manufacturer pages and manuals checked October 16, 2026; food-safety guidance is from FoodSafety.gov/USDA. See our methodology.

Every outage has the same plot twist. First 10 minutes: “This is kind of cozy!” Hour two: someone opens the fridge “just to check,” and the whole family gasps like it’s a horror movie. Hour four: you’re Googling “is mayo still safe.”

A power station that can keep your fridge humming turns that drama into a non-event. Here’s how to pick one that will actually start your fridge and keep it running long enough to matter.

Step 1: Know your deadline

According to FoodSafety.gov (citing USDA), your refrigerator keeps food safe for up to 4 hours during an outage if you keep the door closed. Perishables like meat, poultry, fish, eggs and leftovers should be thrown out after 4 hours without power. A full freezer holds a safe temperature for about 48 hours, or 24 hours if half full and the door stays shut (FoodSafety.gov).

Step 2: Figure out how much energy your fridge uses

Skip the nameplate watts. The compressor cycles on and off, so nameplate watts overstate daily use. Instead:

• Find the yellow EnergyGuide label (or your model’s spec sheet) and read the kWh per year.
• Daily Wh = (kWh per year ÷ 365) × 1,000. Example: 500 kWh/yr ÷ 365 × 1,000 ≈ 1,370 Wh/day, or about 57 W on average.
• Most accurate: a plug-in watt meter for 24 hours.

Then add a margin for losses. Our planning rule is usable Wh ≈ rated Wh × 0.8 (a judgment call based on manufacturer runtime formulas such as BLUETTI’s). Full math: how long will a 2,000 Wh power station run a fridge?

Step 3: Make sure it can start the compressor

Fridges and freezers pull a short startup spike when the compressor kicks on, and that spike can be several times the running draw. Check your fridge’s manual or ask the manufacturer. Then:

• The station’s continuous AC output must exceed everything running at once.
• The station’s surge rating must cover the startup spike.
• Ignore “boost” figures. EcoFlow’s “X-Boost” and BLUETTI’s “Power Lifting” are for heating appliances. BLUETTI’s manuals say Power Lifting isn’t for motor or compressor loads. More: surge vs running watts.

The picks (by published specs)

All prices are brand-store prices on Oct 16, 2026. “Example fridge hours” uses a 500 kWh/yr fridge and our 0.8 rule. It’s illustrative, not a measurement.

Model	Capacity	AC out / surge	UPS	Solar in	Weight	Price	Example fridge hours
Anker SOLIX C2000 Gen 2	2,048 Wh	2,400 W / 4,000 W peak	10 ms	800 W	41.7 lb	$999.99	~29 h
EcoFlow DELTA 2 Max	2,048 Wh (to 6,144)	2,400 W / 4,800 W	not listed	1,000 W	50 lb	$1,049	~29 h (~86 h max expanded)
BLUETTI AC200L	2,048 Wh (to 8,192)	2,400 W / 7,200 W†	≤20 ms	1,200 W	62.4 lb	$899	~29 h (~115 h max expanded)
Jackery Explorer 2000 v2	2,042 Wh	2,200 W / 4,400 W	<20 ms	400 W	39.5 lb	$899 (sold out)	~29 h
BLUETTI Elite 200 V2	2,073.6 Wh	2,600 W / not published for motors‡	≤15 ms	1,000 W	53.4 lb	$899	~29 h
Jackery HomePower 3000	3,072 Wh	3,600 W / 7,200 W	~20 ms	1,000 W	59.5 lb	$1,349	~43 h

† BLUETTI’s AC200L product page lists 7,200 W surge; its user manual lists overload of 3,000–3,600 W for 5 seconds and over 3,600 W for 0.5 s. The two don’t match. Until BLUETTI clarifies, treat 7,200 W as the brand’s headline figure, not a guaranteed compressor-start rating. ‡ BLUETTI’s 3,900 W figure for the Elite 200 V2 is Power Lifting for resistive loads only. We didn’t find a separate motor-surge rating. Ask BLUETTI before relying on it for a fridge.

Best all-rounder for a fridge: Anker SOLIX C2000 Gen 2

A published 4,000 W peak figure, a 10 ms UPS (so the fridge just keeps going when the grid drops) and a manageable 41.7 lb. Its 800 W solar input is mid-pack. Check C2000 Gen 2 price at Anker SOLIX

Best for long outages with solar: EcoFlow DELTA 2 Max or BLUETTI AC200L

Both start at 2,048 Wh and expand: the DELTA 2 Max to 6,144 Wh, the AC200L to 8,192 Wh. The AC200L takes 1,200 W of solar; the DELTA 2 Max takes 1,000 W. Downsides: the AC200L is the heaviest here at 62.4 lb, and EcoFlow doesn’t list a UPS switchover time for the DELTA 2 Max. Check DELTA 2 Max price at EcoFlow · Check AC200L price at BLUETTI

Best value for a fridge and more: Jackery HomePower 3000

About $0.44 per Wh on our check date, with 3,072 Wh and a 7,200 W surge rating. It’s 120 V only and 59.5 lb. Check HomePower 3000 price at Jackery

Fridge outage tips that don’t need a battery

• Keep the doors closed. That’s the single biggest thing FoodSafety.gov recommends.
• When in doubt, throw it out, and never taste food to check if it’s safe (FoodSafety.gov).
• Plug the fridge straight into the power station with the fridge’s own cord (or a properly rated cord). Don’t connect the station to a wall outlet or your home wiring.
