The FO-KOKO IOG-3 is the best portable air conditioner for most camper vans on paper. Its listing declares 6,800 BTU/h (about 1,990 W) of cooling for 550 W, two hoses to the outside, a heat mode and 45 dB in sleep mode. If power draw is your limit, the GEARPASS IOG-2 needs only 400 W. If you want the compressor out of the cabin, the Ivation IVARVAC10 saddles over a window sill.
We ranked four portable air conditioners sold on Amazon.com, all with real compressors, using only their listings and our published scoring. We have not run them in a van. Only four units in our US catalog pass the compressor test, so this list is short on purpose.
FO-KOKO IOG-3 6,800 BTU Dual-Hose Portable AC
1,993 W cooling · 15.9 kg
6,800 BTU/h for 550 W, dual hoses, heat mode and 45 dB in sleep mode.
The catch: Its cooling-per-watt figure is optimistic for a portable and cannot be checked.
GEARPASS IOG-2 5,200 BTU Portable AC & Heater
1,500 W cooling
5,200 BTU/h for 400 W, about 3.3 A at 120 V, with dual hoses and a heat mode.
The catch: No weight and no heating output on the listing.
Ivation IVARVAC10 6,500 BTU Window Saddle RV AC
1,905 W cooling · 21 kg
6,500 BTU/h with the compressor outside the window, 52 dB inside.
The catch: 21 kg (about 46 lb), 650 W and no heat mode.
How do the 4 portable air conditioners compare?
All four run on 120 V and have compressors; they differ in cooling, draw, venting and heat mode. Two use a dual-hose design, one is a window saddle split, and one lists only a drain hose. Empty cells mean the listing does not publish that figure.

Here is the cooling per watt of draw, with BTU/h converted at 0.293 W each:
| Unit | Cooling | Draw | Cooling ÷ draw | Venting |
|---|---|---|---|---|
| FO-KOKO IOG-3 | 6,800 BTU/h (1,993 W) | 550 W | about 3.6 | Dual hose |
| GEARPASS IOG-2 | 5,200 BTU/h (1,500 W) | 400 W | about 3.8 | Dual hose |
| Ivation IVARVAC10 | 6,500 BTU/h (1,905 W) | 650 W | about 2.9 | Compressor outside window |
| Karinear 3,300 BTU | 3,300 BTU/h (967 W) | 436 W | about 2.2 | Not described |
How long will a portable AC run on battery?
Watt-hours × inverter efficiency ÷ watts gives hours at full power. All four run on 120 V, so from a battery they go through an inverter or a power station, which loses around 10-15 %. These figures assume 12 % loss and a fully usable battery:
| Unit | Draw | Amps at 120 V | 1,200 Wh | 2,400 Wh |
|---|---|---|---|---|
| GEARPASS IOG-2 | 400 W | about 3.3 A | about 2.6 h | about 5.3 h |
| Karinear 3,300 BTU | 436 W | about 3.6 A | about 2.4 h | about 4.8 h |
| FO-KOKO IOG-3 | 550 W | about 4.6 A | about 1.9 h | about 3.8 h |
| Ivation IVARVAC10 | 650 W | about 5.4 A | about 1.6 h | about 3.2 h |
Once the cabin is cool, the compressor cycles and the real runtime gets longer. Leave margin for the start-up surge of 2 to 3 times running power; the RV power calculator lets you set duty cycle and inverter use.

The 4 best portable air conditioners, reviewed
1. FO-KOKO IOG-3 6,800 BTU Dual-Hose Portable AC
1,993 W cooling · 15.9 kg
7.5/10 · VanThermia scoreThe IOG-3 has the most cooling here, 6,800 BTU/h, and the best feature set. It uses two hoses to the outside and adds a heat mode of about 2,200 W for cool evenings. The listing says it can run from larger portable power stations and, with adapters sold separately, from an electric car’s vehicle-to-load outlet.
At 15.9 kg it stays under the 20 kg mark our scoring rewards. The doubt is efficiency. 1,993 W of cooling from 550 W is a ratio of about 3.6, high for a portable, and the listing gives no test conditions. Plan your power on the 550 W draw and treat the cooling as a best case.
Pros
- 6,800 BTU/h (about 1,990 W) of cooling for 550 W
- Dual-hose design and a heat mode of about 2,200 W (7,500 BTU/h)
- 45 dB in sleep mode; 15.9 kg (about 35 lb)
Cons
- A cooling-to-draw ratio of about 3.6 is optimistic for a portable and cannot be verified
- 1-year warranty; 45 dB applies to sleep mode only
- Best for
- Camper vans and small RVs on hookups or large power stations
- Skip it if
- Buyers who need a verified efficiency figure

2. GEARPASS IOG-2 5,200 BTU Portable AC & Heater
1,500 W cooling
7/10 · VanThermia scoreThe IOG-2 is the power-miser. At 400 W it draws the least here, so a power station or modest battery bank runs it longest: about 5 hours on 2,400 Wh at full power. It cools at 5,200 BTU/h through two hoses and has a heat mode.
Its declared ratio, about 3.8, is also high for a portable and cannot be checked. The listing omits the weight and the heating output, and the table mislabels it as a split system; it is a single box with two hoses. It is from the same IOG series as the FO-KOKO and carries a 1-year warranty.
Pros
- 400 W draw: about 3.3 A at 120 V, the lowest here
- 5,200 BTU/h (about 1,500 W) of cooling
- Dual hoses, heat mode and 50 dB
Cons
- No weight and no heating output on the listing
- Sized for small spaces: less cooling than the FO-KOKO
- Best for
- Vans running from a power station or small battery bank
- Skip it if
- Hot climates in larger RVs

3. Ivation IVARVAC10 6,500 BTU Window Saddle RV AC
1,905 W cooling · 21 kg
6.5/10 · VanThermia scoreThe IVARVAC10 works differently. It saddles over the window sill, with the compressor outside and the air handler inside, joined by a line through the gap. That keeps most of the compressor noise and heat out of the cabin, and there is no hot-air hose to route.
It declares 6,500 BTU/h of cooling, close to the FO-KOKO, but needs 650 W to do it, a ratio of about 2.9. At 21 kg it is the heaviest here and it has no heat mode. You also need a window that can stay partly open while it runs.
Pros
- 6,500 BTU/h (about 1,905 W) of cooling
- Compressor sits outside the window: less noise and heat inside
- Cools, dehumidifies and runs as a fan; 52 dB
Cons
- 650 W, the highest draw here
- 21 kg (about 46 lb), no heat mode and a 1-year warranty
- Best for
- Vans and trailers with a sliding window you can dedicate to it
- Skip it if
- Battery-only setups or winter use

The Karinear is the smallest unit here. Its listing confirms a compressor, which starts cooling a few minutes after power-on, so it is a real AC and not an evaporative cooler. It declares 3,300 BTU/h for 436 W, 45 dB and 12.7 kg, with a 2-year warranty.
The open question is venting. The listing only mentions a drain hose, not an exhaust for the hot air. Every AC must send its heat outside, so confirm with the seller how this one does it before buying. Its cooling-to-draw ratio of about 2.2 is also the lowest here.
Pros
- Compressor unit: cools, dehumidifies and runs as a fan
- 45 dB and 12.7 kg (about 28 lb), the lightest stated weight
- 2-year warranty, the longest here
Cons
- 3,300 BTU/h (about 970 W): the least cooling
- The listing mentions a drain hose but no hot-air exhaust: check how it vents
- Best for
- Tents and very small sleeping spaces
- Skip it if
- Full-size camper vans in hot weather

How do I vent a portable AC in a camper?
Send the hot air outside through a sealed window or vent panel, and keep the hose short. A portable AC moves heat from the cabin to its hose; if that hose dumps air inside, the van gets hotter. Dual-hose units draw outside air through one hose and blow hot air out through the other.
- Window panel: cut a rigid insert for a sliding window and seal the gaps.
- Short, straight hoses: long or kinked hoses hold heat.
- Condensate: plan where the water goes, into a tank or out through a drain line.
- Security: a window that stays open needs a lockable panel.
For airflow without a compressor, a roof vent fan pulls hot air out at a fraction of the power.
Portable or rooftop: which should I buy?
Choose portable if you cannot or will not cut the roof; choose rooftop if you want the most cooling and a clear floor. The trade-offs are mostly about space, power and installation.
| Portable (these four) | Rooftop or 12 V parking unit | |
|---|---|---|
| Cooling | 3,300-6,800 BTU/h | 8,500-11,000 BTU/h in our catalog |
| Power | 120 V, 400-650 W | 120 V at about 1,300 W, or 12/24 V at 650-960 W |
| Install | Plug in, vent through a window | Roof cut, sealing, heavy wiring for 12 V |
| Space | Takes floor space and hoses | Nothing on the floor |
| Resale | Moves to your next van or home | Stays with the vehicle |
A portable is also the easiest way to test how much cooling you really use before committing to a roof unit. The RV power calculator shows what each option asks of your hookup or battery.
How do I choose a portable AC?
Pick a compressor unit, check its draw against your power, then plan the venting. On a 120 V hookup, any of these four fits. On a power station, draw matters most, and the GEARPASS goes furthest. For cooling a whole RV, a rooftop unit does more; compare them in the best RV rooftop air conditioners.
Our camper air conditioners hub explains rooftop, 12 V parking and portable types side by side.
What are the most common buying mistakes?
The most common mistake is buying an evaporative air cooler and expecting air conditioning. Here are six to avoid:
- No compressor. If the listing never mentions one, it is not an AC.
- Hot air left inside. Without a hose or outdoor unit venting outside, cooling is impossible.
- Believing optimistic efficiency. Ratios near 4 are unusual for portables; plan power on the stated draw.
- Ignoring the surge. Compressors start at 2 to 3 times running power; size your inverter or power station for it.
- Skipping insulation. A hot metal roof adds heat faster than a small AC removes it; see van insulation.
- Forgetting the condensate. Every compressor AC pulls water out of the air. Check where it drains, into a tank or through a hose, before the first hot night.
Which one should I pick by cost level?
Cost level follows cooling capacity and format. We do not list prices because they change daily; check the current listing.
- Entry: Karinear 3,300 BTU. The smallest unit, for tents and tiny spaces.
- Mid: GEARPASS IOG-2 and FO-KOKO IOG-3. Dual hoses and heat modes; pick by cooling versus draw.
- High: Ivation IVARVAC10. The window saddle format keeps the compressor outside.

Frequently asked questions
What is the best portable AC for a camper van?
On paper, the FO-KOKO IOG-3: 6,800 BTU/h (about 1,990 W) of cooling for 550 W, a dual-hose design, a heat mode and 45 dB in sleep mode. It weighs 15.9 kg (about 35 lb) and has a 1-year warranty.
Are 12 V mini air coolers real air conditioners?
No. Evaporative or water-based air coolers have no compressor. They add humidity and cool only a little, less on humid days. A real portable AC has a compressor and sends the heat outside through a hose or an outdoor unit.
Can I run a portable AC from a power station?
Yes, if the station’s inverter covers the running watts plus a start-up surge of 2 to 3 times that. Runtime is roughly watt-hours × 0.88 ÷ watts: a 1,200 Wh station runs a 550 W unit for about 2 hours at full power.
Where does the hot air go in a van?
Outside, through the unit’s hose or hoses and a window or vent panel. The Ivation saddle unit keeps its compressor outside the window instead. If the hot air stays inside, the unit cannot cool the van.
Will a portable AC trip a 15 A outlet?
Unlikely on its own: these four draw 400-650 W, about 3.3-5.4 A at 120 V. Compressor start-up surges reach 2 to 3 times the running power, so avoid starting it while a kettle or heater is on the same circuit.
