A portable air conditioner is the fastest route to real refrigerated cooling when a split system isn't an option — you're renting, you're in an apartment with body-corporate rules, or you simply don't want to spend $2,500+ on installation. The catch is that the category is full of underpowered units that are little better than expensive fans.
Our picks below follow one golden rule: match the kilowatt rating to your room. As a rough guide, allow 1 kW of cooling capacity per 8–10 m² of floor space. Under-size the unit and it will run flat-out all day without ever getting the room comfortable.
| Room size | Floor area | Capacity needed |
|---|---|---|
| Bedroom / study | up to 15 m² | 2.0–2.9 kW |
| Master bedroom / lounge | 15–25 m² | 3.0–3.9 kW |
| Large living area | 25–35 m² | 4.0–5.0 kW |
Best overall
De'Longhi Pinguino Portable Air Conditioner
The Pinguino range has been the benchmark portable air conditioner in Australia for years, and for good reason: it's one of the quietest refrigerated portables you can buy, the dehumidify mode genuinely works on sticky nights, and De'Longhi's build quality means it will still be running in a decade. If you want one unit that just works, this is it.
- Pros: class-leading quiet operation, effective dehumidifier, excellent build quality, simple remote
- Cons: premium price; heavier than budget rivals
Best for large rooms
Dimplex 4.5kW Portable Air Conditioner with Dehumidifier
Most portables give up in open-plan spaces. The Dimplex 4.5 kW is one of the few with the grunt to cool a proper Australian living area, and it consistently ranks among the top-rated large portables in local reviews. If you've been burned by an underpowered unit before, this is the fix.
- Pros: genuine large-room cooling power, built-in dehumidifier, trusted brand with local support
- Cons: big and heavy; higher power draw at full tilt
Best value (medium rooms)
TCL 3.5kW Portable Air Conditioner
TCL has quietly become one of the best value names in Australian air conditioning, and its 3.5 kW portable earns strong owner reviews for straightforward setup and reliable cooling in bedrooms-turned-home-offices. You give up a little refinement versus the De'Longhi, but you keep several hundred dollars.
- Pros: strong cooling for the price, easy single-hose setup, simple controls
- Cons: louder than premium units; basic styling
Best budget (small rooms)
Devanti Portable Air Conditioner (Cooling & Dehumidifier)
Devanti units are the workhorses of the budget end: no frills, but real refrigerated cooling for a bedroom or study at a price that undercuts the big brands by hundreds. Perfect for a rental, a teenager's room, or as a second unit — just keep expectations sized to the price tag.
- Pros: lowest cost of entry to real air conditioning, compact, includes window kit
- Cons: noisier; shorter expected lifespan than premium brands
Best for camping & off-grid
EcoFlow WAVE 3 Portable Air Conditioner
A genuinely different machine: the WAVE 3 cools and heats, runs whisper-quiet, and with the optional battery pack delivers up to eight hours of cordless operation — which makes it the pick for caravans, camper trailers, boats and van life. Overkill for a house; unbeatable away from a powerpoint.
- Pros: battery operation (*battery sold separately), heats and cools, very quiet, app control
- Cons: expensive per kW; small-space cooling only
Best for bedrooms (quiet)
Olimpia Splendid Dolceclima Portable Air Conditioner
Italy's Olimpia Splendid has specialised in portable air conditioning for decades, and the Dolceclima range shows it: slim, genuinely quiet in night mode, and better looking than anything else in the category. If the unit is going next to your bed, this and the Pinguino are the two to shortlist.
- Pros: very quiet sleep mode, compact slim design, quality Italian engineering
- Cons: premium price for the capacity; smaller rooms only
Best reverse cycle (cools & heats)
Devanti 4-in-1 Reverse Cycle Portable Air Conditioner
One machine for the whole year: refrigerated cooling in summer, heat-pump warmth in winter, dehumidifying in between. Reverse-cycle heating moves roughly three units of heat per unit of electricity — far cheaper to run than a plug-in element heater — which makes a 4-in-1 portable the smart buy for anyone in a genuine four-season climate.
- Pros: replaces both an air conditioner and a heater, efficient heat-pump heating, strong value
- Cons: jack of all trades — dedicated units edge it in each single mode

How we choose
Portable Air sold and supported portable air conditioners across Australia from 2011 to 2025, so our shortlists start with what we learned from real customers: which brands generated warranty claims, which units actually cooled the rooms they claimed to, and which features people used after the first week. We then cross-check against current Australian owner reviews and independent testing before recommending anything. We never accept payment from manufacturers for placement — our only income is the Amazon commission, which is the same regardless of which unit you choose.
Frequently asked questions
Do portable air conditioners actually work in the Australian heat?
Yes — provided they're sized correctly and vented properly. The two failure modes we saw constantly were buying a 2 kW unit for a 30 m² room, and running the unit without sealing the window kit so hot air leaked straight back in. Get those two things right and a portable will hold a comfortable temperature through a 38° day.
Are dual-hose units worth it?
Dual-hose designs are more efficient because they don't pull cooled air out of the room to cool the compressor. They're worth seeking out for large rooms and very hot climates, but single-hose units remain fine for bedrooms. Our single vs dual hose comparison covers this in detail.
What about evaporative coolers?
Completely different technology — brilliant in Perth or Adelaide's dry heat, nearly useless in Sydney or Brisbane humidity. See evaporative coolers vs air conditioners before you buy.
