Quick Answer: Pop-up campers split into two real categories most buying guides never separate: older ones running 15-amp shore power (about 1,800 watts total, per standard 120V circuit math) and newer ones with a 30-amp hookup (3,600 watts, the same as a full RV). For an older 15-amp pop-up, the low-draw Midea MAW05R1BWT window unit (5,000 BTU, $170-200) is the safest fit for that tight power budget. For a newer 30-amp pop-up or one with more cooling need, the Whynter ARC-14S dual-hose portable (14,000 BTU ASHRAE, $470-530) has real headroom to spare. Either way, expect to build or buy a rigid mounting panel — most pop-ups only have canvas screened openings, not a glass sash a window AC can hang from.
Search “air conditioner for pop-up camper” and most results just point you toward whatever’s recommended for a full-size RV. That skips the two things that actually make a pop-up different: its shore power is often half an RV’s, and its “windows” are usually canvas screens with nothing solid to mount a unit into. Get either one wrong and you’ll either trip a breaker every time the fridge kicks on, or spend a weekend building a mount that still doesn’t seal.
15-amp vs 30-amp pop-ups — the split that actually matters
| Pop-up generation | Shore power | Total wattage budget | Best AC style |
|---|---|---|---|
| Older pop-up (standard household plug) | 15-amp | ~1,800 watts (120V x 15A) | Low-draw window unit (5,000 BTU) |
| Newer pop-up (angled RV-style plug) | 30-amp | ~3,600 watts (120V x 30A) | Full portable AC (12,000-14,000 BTU) |
The wattage math is the part most guides skip. A 15-amp circuit — the same rating as a standard household wall outlet — delivers about 1,800 watts total at 120V. A 30-amp RV-style hookup, the baseline our RV AC guide uses, delivers roughly double that at 3,600 watts. A compact 5,000 BTU window unit runs at around 450-500 watts, comfortably inside a 15-amp budget on paper — but its compressor’s startup surge (2-3x the running draw for a second or two, the same surge behavior covered in our window AC wattage guide) can still trip a 15-amp breaker if a fridge or fan happens to cycle on at the same moment. A full-size 12,000-14,000 BTU unit, the kind that’s a comfortable fit for a 30-amp RV, is simply off the table on 15 amps.
The mounting problem is separate from the power problem, and just as real. Most pop-up campers have canvas screened openings rather than a house-style glass sash a window unit can hang its weight from. Per pop-up owner installation guides, the common workaround is building or buying a rigid insulated panel cut to fit the window or door opening, then mounting the AC — or a portable unit’s vent-kit port — into that solid panel instead of the canvas. Venting a portable AC through a temporary panel is generally the less invasive route compared to permanently reinforcing a canvas frame to carry a window unit’s weight.

1. Midea MAW05R1BWT — Best Overall (15-Amp Pop-Ups)
Midea MAW05R1BWT (5,000 BTU)
- Running draw sits comfortably inside a 15-amp circuit's ~1,800-watt total budget, with real headroom left for a fridge or a fan running at the same time — the tightest-fitting pick on this list for an older pop-up's power.
- Electronic controls and a remote (the same layout covered in our 5,000 BTU window AC comparison), useful if the unit ends up mounted somewhere in the camper that's awkward to reach.
- Still needs a rigid mounting panel, not the camper's canvas screen, to actually carry and seal around the unit — budget for that as a separate build or purchase, not an afterthought.
Don’t sweat the heat wave — Prime delivers your camper AC in two days. Try it free for 30 days.
At 5,000 BTU this is a small unit even by window-AC standards, but that’s the point on a 15-amp pop-up: the goal isn’t maximum cooling, it’s staying under a breaker that a full-size unit will trip on its first startup surge. If your pop-up’s actual floor space runs closer to 150-175 sq ft and you’ve confirmed 30-amp service, size up to the ARC-14S pick below instead.
2. Black+Decker BPACT08WT — Best Portable / Panel-Vented
Black+Decker BPACT08WT
- Sits fully inside the camper and only needs a hose-sized port through a mounting panel, rather than the AC's whole body — a smaller hole to seal than a window unit's cutout.
- Per pop-up installation guides, venting a portable through a vent-kit port is generally the less invasive option compared to permanently reinforcing a canvas window frame for a window unit's weight.
- Runs on a standard 15-amp-rated cord, but budget the same startup-surge caution as the Midea pick above if your pop-up is on the older, tighter 15-amp service.
This is the pick if your pop-up’s only real opening is a canvas screen rather than anything resembling a house window — a portable’s single vent hose is a far easier thing to seal into a temporary panel than a full window-unit chassis. It also sidesteps the “reinforce the canvas frame” installs some owners attempt with window units, which our venting without a window guide covers in more general detail.
3. Whynter ARC-14S — Best for 30-Amp Pop-Ups
Whynter ARC-14S
- A 14,000 BTU ASHRAE unit draws well within a 30-amp hookup's ~3,600-watt budget, the same math our RV AC guide and tiny-home AC guide use for full-size shore power.
- Dual-hose design avoids pulling warm outside air back in through a pop-up's leaky canvas seams — a bigger issue here than in a hard-sided RV, where single-hose negative pressure is a smaller factor.
- Real cooling capacity for a bigger pop-up (150+ sq ft set up) or one parked in direct sun most of the day, where the 5,000 BTU pick above would run constantly without keeping up.
If you’ve confirmed your pop-up runs the newer 30-amp angled shore-power plug, this is the unit that actually uses that extra headroom instead of leaving it on the table. It’s the same pick our RV guide recommends for a full-size trailer, which makes sense — once you’re on 30 amps, a pop-up’s power situation is functionally identical to a small RV’s.
4. EcoFlow Wave 3 — Best for Boondocking / No Hookup
EcoFlow Wave 3
- Runs on its own DC battery pack, sidestepping the 15-amp-vs-30-amp question entirely for a pop-up parked without any shore power hookup at all.
- The same battery-first pick our tent AC guide and RV guide recommend for off-grid camping — a pop-up dry-camping in a state or national park campground is functionally the same power problem as a tent site with no hookups.
- Real heat mode (6,800 BTU) is a genuine bonus for shoulder-season pop-up trips, where a pop-up's canvas walls lose heat fast overnight.
Plenty of pop-up trips end up at a dry-camping site or a state park loop with no electrical hookups at all, where the entire 15-amp-vs-30-amp question is moot. The Wave 3 is the pick for that trip specifically — it needs nothing from the campsite, just its own charge and, ideally, a solar panel or extra battery pack for a multi-night stay.
How to buy an air conditioner for a pop-up camper
- Check your shore power plug before shopping. A standard 3-prong household-style plug means 15-amp service (~1,800 watts total); the larger angled RV-style plug means 30-amp service (~3,600 watts) — the two support very different AC sizes.
- Budget for a mounting panel as part of the cost, not an afterthought. Most pop-ups only have canvas screened openings, and both window and portable units generally need a rigid panel to mount or vent into rather than the canvas itself.
- On 15-amp service, watch what else is running. A low-draw unit’s startup surge can still trip the breaker if it lands at the same moment as a fridge cycle or a fan — stagger big loads rather than assuming the running wattage alone tells the whole story.
- Size toward 5,000 BTU even though the square footage math suggests less. A pop-up’s thin canvas sides and shell insulate poorly and heat up fast in direct sun, the same reason our tiny-home AC guide flags RV-style oversizing for poorly insulated builds.
- Don’t assume a rooftop RV-style unit is an option unless your pop-up has a hard, reinforced upper shell — most soft canvas roofs simply can’t carry the weight.
The bottom line
If your pop-up runs the older 15-amp shore power, the low-draw Midea MAW05R1BWT is the safest fit for that tight wattage budget, and the Black+Decker BPACT08WT is the easier install if your only real opening is a canvas screen rather than a window. If you’ve confirmed newer 30-amp service, the Whynter ARC-14S has real cooling headroom to spare. And if you’re dry-camping with no hookup at all, the EcoFlow Wave 3 sidesteps the whole amperage question. Check your plug and your opening type before you buy — both matter more than raw BTU on a pop-up.
