Mini wearable personal air conditioner

By grape Japan

Summer in Japan can be grueling, with a combination of heat and humidity often overwhelming the most seasoned travelers, with cases of heatstroke and dehydration occurring often. So as you can imagine, it's quite easy for those who live in Japan to rack up quite the air conditioning bill. While not entirely a new concept, Sony is hoping to alleviate some of the burden of Japan's cruel summers with a wearable air conditioning device, which users can control via a smartphone app.

The device is called Reon Pocket, and was initially announced on Sony's crowdfunding site where it has already passed its goal. The Reon Pocket is sold together with a shirt equipped with a pocket, conveniently located on just below the neck, to insert the portable air conditioning unit. Users can adjust the temperature from their smartphone, providing cooling in hot weather and heating during colder seasons.


The unit lasts around 90 minutes and requires a two hour charging period. Currently, the minimum crowdfunding contribution (14,080 yen) provides one unit and one shirt.

Cool, but very expensive. I'd like to see one - wondering where the heat is dissipated.

I’ll take a splash or two of water on my face-quite a lot cheaper!

A/C units are heat exchangers, and since they need energy to operate, are net heat producers. I am guessing that these units cool down one side, while heating up the other side. If they work too efficiently, there would be a danger of burning the shirt.

Where does the generated heat go? Does it come out the back and ensures those standing behind you on the train gets a horrible blast of hot, fetid air? Sounds rather selfish and self defeating. Also, it only lasts 90 minutes and takes two hours to charge. No.

Is this just a slimline fan?

On the site they're sold out of preorders but it's foolish to preorder something like this anyway, just wait for the retail version as there are many potential problems this device can have but if it works perfectly you can just buy it at retail release. Certainly if it works I'll look into it, probably wait for a revision 2.

I do not think it really is that hot outside. People need to step up to the plate and quit complaining. Soldiers in the past never complained, but now everyone is so wimpy.

Well, some people are collapsing and some dying.

That’s hot enough.

Meanwhile, in China, millions of cheaper versions are probably already being made.

I'll wait for the Daiso version, thanks Sony.

Yeah, but do you want to risk putting something like that next to the skin, and if it doesn't feel cool enough you'll be kicking yourself :-)
