CPAP camping is the case where sizing errors have consequences beyond inconvenience, and it is also the case where the published guidance is least useful. Manufacturer blogs quote the blower's draw and skip the humidifier. Camping sites quote a nightly figure without saying which configuration it assumes. The gap between those two numbers is roughly threefold.
The two configurations, and what each costs
| Configuration | Average draw | Per 8-hour night |
|---|---|---|
| Blower only, lower pressure | 20-35W | 160-280Wh |
| Blower only, higher pressure | 40-60W | 320-480Wh |
| Blower plus heated humidifier | 70-95W | 560-760Wh |
| Blower, humidifier and heated tubing | 85-120W | 680-960Wh |
The heated humidifier is a resistive heating element. It is subject to the same rule as every other heating load in this category: heating is expensive, and there is no efficient way to do it. Turning it off is the single biggest lever available, and in humid or cool conditions many people find it acceptable — but that is a conversation with your clinician, not a spec decision. Full arithmetic here.
Run it on DC if you can
Most CPAP machines are DC devices with an external power brick. Plugging one into a power station's AC outlet means converting battery DC to AC in the inverter and then back to DC in the brick — paying twice, typically 10-20% in total. Many manufacturers sell a 12V DC cord that runs the machine straight from the car socket, skipping both conversions.
On a small battery this is not a marginal saving. It can be the difference between finishing the night and not. It also keeps the power station's inverter switched off, which removes its idle draw and its fan noise — both welcome at 3am in a tent.
Nights per charge, by capacity
| Capacity | Humidifier off (~35W) | Humidifier on (~85W) |
|---|---|---|
| 286Wh | About 1 night | Under half a night |
| 288Wh | About 1 night | Under half a night |
| 1,024Wh | 3-4 nights | About 1.2 nights |
| 1,070Wh | 3-4 nights | About 1.3 nights |
| 1,152Wh | About 4 nights | About 1.4 nights |
The pattern is stark: with the humidifier off, a small unit is a night and a 1kWh unit is most of a long weekend. With it on, even 1,152Wh is barely over one night. If you need the humidifier and you are out for more than a night, you need solar — best solar generator for camping is the next page to read.
The picks in full
1. Best for one night, humidifier off
EcoFlow RIVER 3 Plus
- 286Wh
- LiFePO4
- 600W continuous / 1,200W surge
- 10.4 lb
- 220W
- 3,000 cycles to 80% capacity
- 0-100% in 60 min
- Not published on the US product page
10.4 lb and 286Wh is the smallest, lightest honest answer to CPAP camping. At a typical 35W blower draw running on DC, this covers a full eight-hour night with a margin, and it weighs little enough that you will take it to a walk-in pitch rather than leaving it in the car.
The expansion path matters here more than on most pages. If your trips vary between one night and four, the 858Wh ceiling with an extra battery means one purchase covers both rather than forcing you up to a 1kWh unit you carry unnecessarily on short trips.
It will not cover a humidified night, and it is important to be direct about that: at 85W average the 286Wh runs out around the three-and-a-half-hour mark. If the humidifier is not negotiable, skip to the larger picks.
Reasons to buy
- 10.4 lb — carryable to any pitch
- 286Wh covers a full night with the humidifier off
- Expands to 858Wh for longer trips
- 60-minute full recharge
- 3,000 cycles to 80% LiFePO4
Reasons to avoid
- Will not cover a humidified night
- EcoFlow does not publish a warranty term on the US page
- 220W solar input is modest for multi-night recovery
- The expansion battery is a large additional cost
Buy it if: one or two nights, humidifier off, and you carry your own gear to the pitch.
Skip it if: you need the heated humidifier. This is under half a night in that configuration.
2. Best for a long weekend
Jackery Explorer 1000 v2
- 1,070Wh
- LiFePO4 (LFP)
- 1,500W continuous / 3,000W surge
- 23.8 lb
- 400W
- 4,000 cycles to 70% capacity
- 1.7 hr wall; 1 hr emergency charge via app
- 5 years (with registration)
1,070Wh with the humidifier off is three to four nights, which covers essentially every long-weekend trip without any need to recharge or deploy panels. That is the practical sweet spot for CPAP camping, and it is why this is the pick for most people on this page.
The 12V/10A car socket is the port to use — a manufacturer DC cord for your machine plugs straight in and the inverter never starts. That saves roughly 12% of every night's consumption and, just as usefully, means the unit's cooling fan stays silent. On a 1,070Wh battery that is the difference between three nights and four.
With the humidifier on it is about one and a third nights, which is an awkward number: enough for one night and not enough for two. If that is your configuration, plan on solar or size up.
Reasons to buy
- 1,070Wh — three to four nights with the humidifier off
- 12V/10A socket for direct DC operation
- 23.8 lb, the lightest 1kWh unit here
- Below 22 dB in silent mode, which matters overnight
- 1.7-hour wall recharge; 5-year warranty
Reasons to avoid
- About 1.3 nights with the humidifier on
- 400W solar input is the lowest of the 1kWh units
- Not expandable
- Cycle rating quoted to 70% rather than 80%
Buy it if: a three or four night trip with the humidifier off, and you want to carry as little as possible.
Skip it if: you run the humidifier nightly on a long trip. Add solar or go bigger.
3. Most nights per charge
BLUETTI AC180
- 1,152Wh
- LiFePO4
- 1,800W continuous / 2,700W surge
- 35.27 lb
- 500W
- 3,500+ cycles to 80% original capacity
- 1.3-1.8 hr full (1,440W max AC input)
- 5 years
1,152Wh is the largest battery in this class, and for a CPAP that translates directly into about four nights with the humidifier off — the most of anything here. If the unit stays in the vehicle and you drive to your site, the 35.27 lb stops being a meaningful objection.
The 12V/10A DC socket is there for direct machine operation, and the four AC outlets mean the CPAP can share the unit with a fridge, a light and a phone charger without any shuffling. The 20 ms UPS switchover also means you can leave it plugged in at home between trips with the machine on it, and a household outage never interrupts a night.
That last point is worth more than it sounds for a CPAP user specifically. A unit that doubles as a bedside UPS is being useful 365 nights a year rather than six.
Reasons to buy
- 1,152Wh — about four nights with the humidifier off
- 12V/10A socket for DC operation, four AC outlets
- 20 ms UPS makes it a bedside backup at home too
- 3,500+ cycles to 80% — longest rating here
- 5-year warranty
Reasons to avoid
- 35.27 lb — this is a vehicle-based unit
- About 1.4 nights with the humidifier on
- 500W solar input is mid-pack
- Not expandable
Buy it if: you drive to your site and want maximum nights, and would use it as a home UPS too.
Skip it if: you walk to your pitch. The weight is a third more than the Jackery for 8% more battery.
4. Best if you run the humidifier every night
EcoFlow DELTA 3 Plus
- 1,024Wh
- LFP (LiFePO4)
- 1,800W continuous / 3,600W surge
- 27.6 lb
- 1000W
- 4,000 cycles to 80%+ capacity
- Full in 56 min (1,500W AC input)
- 5 years
If the heated humidifier is not optional, capacity alone will not solve your problem — at 85W average you are consuming most of a kilowatt-hour a night, and no portable battery holds a week of that. The answer is recharge rate, and this unit has the best of it: up to 1,000W of solar input across two MPPT channels.
A 400W array in decent conditions puts back well over a humidified night's consumption during a single day, which converts a finite battery into a sustainable one. That is a categorically different trip from rationing nights.
It also expands to 5kWh, so bad-weather margin is purchasable rather than a matter of luck. At 27.6 lb it is heavier than the Jackery, but if your alternative is not sleeping properly, that is not the relevant comparison.
Reasons to buy
- Up to 1,000W solar input — recharges faster than a humidified CPAP consumes
- Expandable to 5kWh for bad-weather margin
- 1,024Wh base is about 1.2 humidified nights
- Under 10 ms UPS; IP65 rated
- 4,000 cycles to 80%+, 5-year warranty
Reasons to avoid
- 27.6 lb and a panel array is a lot of kit to bring
- The 1,000W figure needs two separate arrays
- Base capacity alone is barely over one humidified night
- Meaningful extra cost once you add panels and expansion
Buy it if: multi-night trips with the humidifier running, and you are willing to carry panels.
Skip it if: you camp one night at a time. Buy the lightest unit that covers a single night instead.
