EWT 3.3kW Portable Air Conditioner Review
R290 refrigerant, a genuinely low environmental impact, and a real 4.5★ rating from JB Hi-Fi buyers — but at 24kg, and with only a 1-year warranty, here's what the spec sheet doesn't tell you before you call it 'portable'.

EWT
EWT 3.3kW Portable Air Conditioner
From A$799.00
4.5★ (6 reviews) on JB Hi-Fi
- + 3.3kW cooling, rated for rooms up to 22m² — check this against your actual room with our room-size calculator
- + Uses R290 refrigerant rather than older HFCs — lower environmental impact
- + 24-hour timer and 3 fan speeds, with a dehumidifying mode for humid coastal nights
- − 4.5★ is from only 6 reviews — a genuinely good rating, but thin sample size compared to how heavily-reviewed split-system units are
- − At 24kg it's genuinely heavy to move between rooms despite being called portable — check you're comfortable shifting that weight before buying
- − Only 1-year manufacturer's warranty — short next to some split-system alternatives that carry 5+ years
Our verdict
A genuinely capable portable unit for a single room where installing a split system isn't an option — R290 refrigerant is a real environmental plus most portable ACs at this price don't offer, and 4.5★ from 6 JB Hi-Fi buyers is a solid, if still fairly small, sample. The honest trade-offs are the ones every portable AC shares: a heavy 24kg unit that's portable in name more than practice, and a 1-year warranty that's short next to a split system's typical 5+ years.
This review is built from EWT’s own published specifications and JB Hi-Fi’s real buyer rating — we haven’t tested this unit ourselves, and JB Hi-Fi’s listing doesn’t display individual review text for this model, only the aggregate rating.
Who it’s actually good for
If you need real, active cooling for a single room and a split system isn’t an option — renting, strata restrictions, or just not wanting a permanent installation — this is a genuinely reasonable pick. R290 refrigerant is the standout real feature at this price point: a meaningfully lower environmental impact than the older refrigerants some budget competitors still use, not just a spec-sheet checkbox. The dehumidifying mode and 3 fan speeds cover the basics without unnecessary complexity, and a 24-hour timer means it’s easy to have the room cool before you’re in it.
Who should look elsewhere
If installation is genuinely possible for your situation, a split system is the better answer on every axis that matters long-term — lower running cost, quieter operation, and in several states, a real rebate that a portable unit doesn’t qualify for at all. See our state-by-state rebate breakdown before assuming portable is the cheaper overall choice once running costs and available rebates are factored in. And if you’re in a genuinely dry climate zone, an evaporative cooler is worth comparing too — cheaper to buy and run, though it won’t match this unit’s cooling in humid conditions.
The real numbers
- Cooling capacity: 3.3kW, rated for rooms up to 22m²
- Modes: cooling, dehumidifying, fan — 3 speeds
- Refrigerant: R290, GWP around 3
- Operating range: 16–31°C ambient, thermostat range 0–65°C
- Timer: 24-hour
- Weight: 24kg
- Warranty: 1 year, manufacturer
- Buyer rating: 4.5★ from 6 reviews on JB Hi-Fi
This is a portable unit, not a permanent installation — if you haven’t ruled out a split system yet, our split-system buying guide covers sizing, installation, and the real rental/strata approval process. And if you’re still deciding between cooling methods generally, our full climate-based comparison covers where each one actually wins.
How it compares

Westinghouse
Westinghouse 3.6kW Split System Reverse Cycle Air Conditioner WSD36HWA
Full review →From A$848.00
4.7★ (50 reviews) on Appliances Online
- + 4.68★ from 50 reviews — a genuinely large, trustworthy sample for a split system at this price point
- + Sleep Mode automatically adjusts temperature and fan speed overnight, and FollowMe adjusts based on your remote's location rather than the wall unit's own sensor
- + Self-clean function and app control (+Home) included as standard, not a premium add-on
- − Appliances Online showed A$848 on 2026-10-14, which it described as 49% off an RRP of A$1,649; our August check had it at A$1,569, so this looks like a sale price that may not last
- − 3.6kW suits a single bedroom or small living area — check actual room size with our room-size calculator before assuming it covers an open-plan space
- − Installation is a separate, quoted job on top of the unit price — this figure is the hardware only
- − Reverse-cycle systems like this need a professional installer for the outdoor unit and refrigerant lines, not a DIY job

Bonaire
Bonaire Profile 3D 12i Portable Evaporative Air Cooler
Full review →From A$278.00
4.1★ (28 reviews) on Harvey Norman
- + 28 reviews at 4.1★ — a genuinely larger review sample than most evaporative coolers this size
- + Remote control with a magnetic dock and off-timer, plus multi-directional wheels for moving it between rooms
- + Bonaire is an Australian cooling specialist brand, not a generic imported appliance
- − 12L tank is smaller than larger units in this category — expect more frequent refills on hot days
- − Touch control panel rather than physical buttons, which some reviewers find less intuitive
- − Like any evaporative cooler, it's only genuinely effective in dry climates — check the guide's climate breakdown before buying
Frequently asked questions
- Is a portable AC like this actually worth it over a split system?
- Only if installing a split system genuinely isn't an option for you — renting without landlord consent, a strata building that says no, or simply not wanting to commit to a permanent installation. A split system will out-cool and out-run-cost this unit in every case where installation is possible; portable AC exists specifically for when it isn't. See our split-system buying guide for how the installation approval process actually works before ruling it out.
- What does R290 refrigerant actually mean for me?
- It's a genuinely lower-impact refrigerant choice — R290 (propane) has a Global Warming Potential of around 3, compared to several hundred for older refrigerants still used in some budget units. It doesn't change how the unit cools day to day, but it's a real, meaningful environmental point in the EWT's favour if that factors into your decision, and it's mildly flammable, which is why the unit (like any R290 appliance) is designed and certified with that specifically in mind.
- Does this qualify for any of the state rebates?
- No — every current Australian state rebate scheme we've verified (Victoria's VEU, the ACT's schemes, NSW's Energy Savings Scheme) applies specifically to reverse-cycle systems replacing another heating source, not to portable air conditioners. See our state-by-state rebate breakdown for the current detail. That's a genuine point in the split-system's favour if you're comparing purely on total cost and a rebate is available where you live.
- Is 24kg actually a problem for a 'portable' unit?
- It's worth knowing before you buy rather than after — most portable ACs in this weight range come with castors specifically because they're not meant to be lifted, only rolled. Moving it between rooms on a flat, unobstructed floor is fine; carrying it up or down stairs regularly is a genuinely different proposition than the word 'portable' implies.
