Best picks
The Princess 358670 is the clearly documented smart pick, with app and voice control. Compare it with other verified evaporative models if remote connectivity is not essential.
Quick answer
The Princess 358670 Smart Air Cooler is the standout if app and voice controls are priorities. The Tristar AT-5470BS is a wheeled alternative, while Blaupunkt ACF601 offers two-plane oscillation and Gree's KSWK-06T60D has a removable 6-litre tank. These are evaporative appliances, not compressor air conditioners.
Best for app-connected controls
Drawback: The maker lists a 62 dB noise level, and the cooler has no built-in compressor.
Best for moving between rooms
Drawback: Tristar does not publish a suitable room-size figure for this model.
Best for adjustable air direction
Drawback: Its evaporative system adds moisture to the airflow, so it may not suit every room condition.
Best for a removable tank
Drawback: The official page gives limited detail about controls and dimensions.

Best for a larger tank and castors
Drawback: The brand's copy varies on the swing angle, so confirm the supplied model details before purchase.

Common questions
Yes. Princess lists an app and voice control, alongside a remote control. Its page specifies single-band 2.4 GHz Wi-Fi.
No. The 358670 has no built-in cooling compressor; it uses water-assisted airflow. It does not remove heat from the room in the way a compressor air conditioner does.
Princess specifies a retractable 3-litre reservoir. Check the manual for filling and cleaning instructions.
Consider the controls supplied with the exact model. The Princess includes a remote, so its basic operation is not solely app-dependent.

A portable air cooler can mean an evaporative unit, a fan or a portable air conditioner in shopping results. Identify the cooling method before choosing a model.
A portable air cooler is not automatically an air conditioner. Check whether the appliance evaporates water, simply moves air or uses a refrigeration system.
A portable air cooler unit must be practical to live with. Measure its position, plan water access and read the cleaning routine before focusing on extra modes.
The best portable air cooler is one that suits the room's humidity and ventilation. Compare these real evaporative models only after confirming that this cooling method meets your needs.
