For backing up a refrigerator and a CPAP machine during a power outage, I'd prioritize a portable power station with a large LiFePO₄ battery, a pure sine wave inverter, and foldable solar panels. The goal is to keep food cold, maintain reliable overnight CPAP power, and recharge the battery during daylight.
The best setup depends on how long you need to run the appliances. For most households, I'd start by looking at a 2,000–3,000 Wh power station paired with 400–600 W of solar panels. That's a useful middle ground between portability, cost, and backup capacity, although cloudy weather and frequent refrigerator compressor cycling can reduce runtime.

A strong balance of battery capacity, output, and solar recharging. The 2,048 Wh power station class is a good starting point for a refrigerator plus CPAP, and the 400 W panel is more useful for multi-day outages than a small 100–200 W panel.
Listed bundle price at Eco Solar Kits
A good alternative if you want a straightforward kit from an established portable-power brand. The power station has a 2,042 Wh battery and 2,200 W output, providing a reasonable balance of capacity and portability. Check exactly which solar panels the bundle includes before ordering.
Power station only; panels sold separately
Best if you want a more substantial backup system. Its 3,840 Wh battery, 6,000 W output, and expandable capacity give you more room for longer outages and additional appliances. Budget separately for compatible solar panels.
Prices are listed prices found during this search and can change. My first choice for most people is the Anker C2000 Gen 2 with a 400 W panel, provided its output and solar-input specifications match your particular appliances and needs.
Typical estimates vary by appliance and operating conditions:
| Appliance | Approximate energy use |
|---|---|
| Refrigerator | 1,000–2,000 Wh per day |
| CPAP for 8 hours, without heated humidification | 240–480 Wh |
| CPAP for 8 hours, with heated humidification | Often 400–800+ Wh |
A refrigerator cycles on and off, so its daily energy use matters more than its running wattage alone. Its compressor may also require a brief surge when starting. CPAP consumption can increase considerably with heated humidification and a heated hose.
For a rough illustration, a 2,048 Wh battery might deliver around 1,700 Wh of usable AC energy after conversion losses. That could cover a refrigerator using 1,200 Wh per day and a CPAP using 400 Wh overnight for roughly one day, but not necessarily a full 24 hours plus a comfortable reserve. Solar input can extend that runtime.
Overnight or short outage
Around 1,000–1,500 Wh with a 200 W panel. Good for CPAP and selected essentials, but limited for running both a refrigerator and CPAP for long.
One to two days, with sunshine
Around 2,000–3,000 Wh with 400–600 W of compatible panels. This is the range I'd recommend for your two appliances.
Several days or recurring outages
Consider 4,000 Wh or more, expandable batteries, and 800 W or more of compatible solar input. You'll want enough sunlight and panel capacity to replace the energy you use each day.
Two details will make the recommendation much more accurate: your budget and how long you need backup power.

To safely and reliably run a standard refrigerator (which cycles on and off, pulling about 1,200--1,800W on surge and ~ 100--200W continuously) alongside a medical-grade CPAP machine (~ 30--60W with heated humidifier off, or more with it on) during a blackout, you need a system with at least a 1,000Wh to 2,000Wh capacity and a pure sine wave inverter of ≥ 1,800W.
The top-performing solar generator and portable solar panel combinations ideal for this specific pairing balance high capacity, fast solar recharging, and reliable LiFePO4 (LFP) battery chemistry:
Widely considered the best value and most versatile mid-sized combo. It features a 1,024Wh capacity and an 1,800W output (which can surge to 2,400W), easily handling a fridge compressor kicking on while your CPAP runs. The 220W bifacial panel captures ambient light from the back to speed up recharging, and you can expand the capacity later by adding an extra battery if you face multi-day outages. You can view details on the EcoFlow DELTA 2.
If you want extended runtime to keep food fresh for 24+ hours without stressing about running low, this setup offers a robust 2,042Wh capacity and a 2,200W AC output. The two included 200W SolarSaga panels use high-efficiency TOPCon cells to completely recharge the station via sunlight in roughly 7.5 hours. It operates very quietly (<30dB), making it unobtrusive if placed in a bedroom or living space. Check specifications and bundles via the Jackery Explorer 2000 v2.
A phenomenal space-saving alternative that punches above its weight class. It boasts a 1,056Wh capacity and a massive 2,100W output (surging to 3,100W) driven by ultra-durable LiFePO4 batteries. It features hyper-fast recharging speeds and a compact footprint that is easy to store near a nightstand or kitchen. More details can be found on the SOLIX C1000.[1][2]

EcoFlow DELTA Pro 3 is the most capable option of these for a serious outage kit: 4,096 Wh, 4,000 W AC output, 120/240 V, and expandable capacity. It can accept substantial solar input, which matters if an outage lasts several days.
EcoFlow DELTA 3 Ultra Plus is interesting if you want something less expensive and considerably easier to move. The current listing shows 3,072 Wh, 3–11 kWh expandable capacity, and smart output prioritization.
Jackery HomePower 2000 Plus v2 is a good middle-ground option: about 2,048 Wh and 2,400 W, with expansion to 12 kWh. The current bundle I found includes a 200 W panel.
Anker SOLIX F3800 moves into serious home-backup territory: 3,840 Wh and 6,000 W, with native 120/240-V capability. It's substantially heavier, though—about 132 lb.
If you're trying to cover only refrigerator + CPAP + modem/router + a few lights/phones, I wouldn't automatically spend $4,000–$5,000 on a whole-home system.
A ~2–3 kWh station + 400–800 W of portable solar panels is a sensible target.
Why? A refrigerator's compressor cycles rather than running continuously, while a CPAP is comparatively tiny. One independent test found roughly 30 hours of refrigerator runtime from a ~2 kWh station under its test conditions, while a 4 kWh DELTA Pro 3 lasted substantially longer. Actual refrigerator runtime varies dramatically with refrigerator efficiency, room temperature, and how often the door is opened.
For multi-day blackouts, solar becomes the important part. A larger battery doesn't help indefinitely if you can't replenish it. I'd rather have a 2–3 kWh battery with 600–800+ W of foldable panels than a huge battery with only a small 200-W panel.
If your CPAP supports DC operation, that's worth investigating. Running it directly from an appropriate DC output can avoid the power loss associated with converting battery DC → AC → CPAP power supply. And if you use a humidifier/heated tubing, your overnight consumption can be considerably higher than with the blower alone.
Bottom line: For a portable emergency setup, I'd target 2–4 kWh + 600–1,000 W portable solar. The DELTA Pro 3 is the high-capacity choice; the DELTA 3 Ultra Plus or Jackery HomePower 2000 Plus v2 make more sense if you want something more manageable and less expensive.
If you tell me (1) your refrigerator's approximate wattage/model and (2) your CPAP model, I can calculate how many hours/days each system would realistically run them and how many portable panels you'd need, including a cloudy-day scenario.
