Who this model may suit—and the main trade-off
The compressor remains in the room. Compare the published 55 dB sound evidence, window fit and hose route before treating the BTU rating as a complete answer.
Regular quieter cooling or several rooms matter more than portability; compare a professionally designed split system before buying multiple portable units.

Directly comparable: The same defined field is present in the verified product record.How we compare this model
Portable-v1.0 compares verified specifications against fixed portable-air-conditioner category benchmarks. The internal comparison covers output per rated watt (35), maximum noise (25), weight (15), warranty (10) and verified features (15).
Capacity itself earns no points because the right BTU depends on your room. This is not an efficiency label, product review or laboratory test, and it does not include price or affiliate value.

Product information and documents
What to know about the Airmaster ACPO12P
CoolCompare has organised the manufacturer-published information below. It is not a hands-on review or a laboratory result.
A 12,000 BTU portable air conditioner with fan and dehumidifier modes.
Airmaster publishes 12,000 BTU cooling, 1,350 W rated cooling input, a single 55 dB sound value, 300 m³/h airflow and suitability for rooms up to 20 m². The exact ACPO12P uses R290 refrigerant, a 13 A three-pin UK plug and a 1.5 m exhaust hose. Its 3.45 L/hour published moisture-removal rate is shown as a mathematical 82.8 L/day equivalent, not a real-world continuous extraction claim.

Features and practical meaning
12,000 BTU/h cooling
Published cooling capacity. Use the room-fit result rather than capacity alone, especially for sunny, open-plan or poorly insulated rooms.
55 dB published sound
Compare the stated measurement with other models on the same basis. A portable compressor remains inside the room.
1,350 W rated input
This verified input is the starting point for the running-cost calculator. Real consumption can vary as the compressor cycles.
Outdoor exhaust required
The published exhaust-hose length is 1.5 m. Hot air must be vented outside without extending or sharply bending the hose beyond manufacturer limits.
Window-kit status needs checking
The reviewed evidence does not support an included kit claim; budget for a compatible seal only after checking the opening.
36.5 kg unit weight
Check stairs, thresholds, storage space and the route between rooms. Castors do not remove the need to move the unit safely.
Dehumidifier mode listed
This mode can remove moisture, but published litres-per-day figures and drainage arrangements should be checked before choosing it for dedicated damp control.

Read the source-review note
Human-reviewed current CED product page on 20 August 2026. The exact page showed zero distributor stock; that is not treated as a nationwide availability claim and no retailer offer is created. The single 55 dB value has no published measurement context, so repeating it in required min/max fields does not claim an operating range. The 3.52 kW field is a transparent BTU conversion. The 82.8 L/day field is 24 times the published 3.45 L/hour rating and is not a continuous real-world extraction promise. Ducting and a remote are listed; a window sealing kit is not inferred.

How to check this model before buying
CoolCompare does not currently send product traffic to an affiliate retailer. Use the exact model code ACPO12P when checking retailers, then confirm the seller, total delivered price, returns route, warranty provider and stock at the destination.
No current price or stock is shown because no fresh, independently checked retailer record is available.
Estimate electricity cost from verified power input
The rated input for this model is 1350 W. Use your own tariff without assuming a purchase price.

Portable-unit setup matters
Vent hot air outside, keep the exhaust hose within the manufacturer’s permitted arrangement and seal gaps around the window kit. Poor venting can return warm outside air to the room and reduce useful cooling.

Frequently asked questions
What room size is the Airmaster ACPO12P suitable for?
The published recommendation represented in the CoolCompare catalogue is Up to 20 m². Actual cooling demand also depends on ceiling height, insulation, glazing, sun exposure and internal heat, so use the BTU calculator before choosing.
How noisy is the Airmaster ACPO12P?
The reviewed source publishes a single 55 dB sound value. It is not presented as an operating range; measurement type, room acoustics, fan mode and distance all affect comparisons.
How much electricity does this portable air conditioner use?
Its verified rated input is 1350 W. Rated input is not a promise of constant consumption because compressors can cycle. Use your electricity tariff and expected hours in the running-cost calculator for a transparent maximum-input scenario.
Does a portable air conditioner need to be vented outside?
Yes. A compressor-based portable air conditioner must discharge hot air outside through its exhaust hose. Keep the hose as short and straight as the manufacturer allows and seal the window opening; never extend or alter it contrary to the manual.
