Wearable Air Conditioner By Sony. Introducing The REON Pocket

News just in about a new wearable air conditioner from Sony, called REON Pocket.

The REON Pocket is a wearable peltier device, about the size of a mobile smartphone, capable of cooling as well as heating.

It releases cool (or warm) air through a small rear panel.

At the time of this writing, the initial plan is to offer the REON Pocket as a stand alone device, with a companion undershirt.

The undershirt is equipped with a pocket in the upper middle back, allowing the device to be removed so that the undershirt can be laundered.

Reports state that the makers are recommending using the unit in 15-minute increments.

Sony is gauging interest in the product via their “First Flight” crowdfunding campaign site. As such, the product will launch only if it meets its funding goal.

Reon Pocket User Manual & App Question

Got this question from a visitor who was looking for some help understanding how to use the Reon Pocket:

Hi there, I just bought a Reon Pocket. I want to love and use it, but literally have no idea how to get the app / user guide!

I don’t read or speak any Japanese! Did you find an English version?



I contacted some folks over at Sony who are involved with the Reon Pocket program, and asked them for some help.

Got some information from them, and replied to Jake with the following information.

The Reon Pocket App:

This is what Sony said about the Reon Pocket App:

He can download the app for the REON POCKET from google play/app store if he is able to access to those stores for Japan, but the language of the app is only Japanese.

So, if you want to use the app and living outside Japan, you may have to install a VPN app on your phone, set it to Japan, and see if you can find & download the app in the associated app store of your mobile phone.

My guess is that you’d only need to use the VPN app to download it, but they may restrict usage too. You’ll just have to test it to know.

Since it’s in Japanese, my best recommendation would be to try and find a Japanese-to-English translator in your area to help you figure out how to use it. There are mobile screen sharing apps, so maybe you can do it remotely if you can’t find someone to do it person.

The Reon Pocket User Manual:

A quick hack to translating the printed Reon Pocket user manual into Japanese would be to use Google Translate from your phone. On android (which is what I use) it gives you the ability to take a photo of something and translate it. It also has a “live” translation where you can point your camera at any text, and it will translate it.

I’ve used the Google Translate mobile app several times when traveling overseas, and it does help quite a bit.

You can also find the reon pocket user manual here.  It’s still in Japanese, but you can use Google Translate in Chrome to translate it in real-time.

Reon Pocket Review, Usage & Feedback

If you get the Reon Pocket up and running, can you email me back to let me know how it’s working for you? Maybe provide a mini-review of it so I can share the info on my site?

Please let me know and keep me posted (:
