The review covers the product features and setup, followed by the cooler's performance.


This just couldn’t be simpler. The unit is fully assembled and ready to go. Just pour in water, through the open hinged lid, up to the level shown on the clear water level window.

Stand it in an upright position wherever you want it.

Plug into a power source and turn on.

That’s it!

In use

The on switch is combined with the speed regulator knob. Power consumption is claimed to be 0.7amps at low speed, 1.3amps at medium and 1.7amps at high speed.

With a new unit or when its not been used for a while it may take up to 30 minutes to achieve maximum cooling effect. This is simply to allow thorough water uptake in the dry cooling pad.

The water in the internal tank should last for over 8 hours at high speed but with the external tank fitted this is extended to over 30 hours. The external tank is connected to the unit via the supplied tube and must be sited higher than the unit to allow a gravity feed.

The cooler can be used while driving and it is recommended that the water level should not exceed half full whilst on the move - unless the external tank is used as there is a float mechanism within the unit to keep the internal tank at the half full mark.

Although this review is motorhome related the air cooler can be used almost anywhere because it’s so portable - house, caravan, boat, car, tent, even outdoors.


The outgoing airstream from the unit will be up to 45% lower than the ambient air (this can be less in a very humid climate) and the unit has a range of around 8 metres.

It’s recommended to add just a couple of drops of Eucalyptus or Tea Tree Oil to the tank every couple of fills to prevent bacteria growth over time.

Other oils such as Olbas and Lavender can also be added to scent the air and Citronella is perfect for keeping bugs away - especially when sitting outside as anything or anybody within range will be protected by a very fine mist that settles from the airstream. (We’re particularly keen to see how this bonus feature works!)

First impressions

We were very impressed when we saw this cooler at a motorhome show and we’re also impressed with it in use albeit just briefly at the time of writing this review.

We will be trialling this over a long period to see how effective it is on our travels.

In the meantime the TRANSCOOL 12V Evaporative Cooler is available from Transcool and is discounted to Club Motorhome members.
