Worn under the shirt, the Reon Pocket Pro\u2019s placement is important for optimal performance | Image: Xataka<\/span>\n <\/div>\n<\/p><\/div>\n<\/div>\n What is a Thermal Dissipator?<\/strong> At first mention, it sounds peculiar\u2014almost as odd as hitting the gym with an exoskeleton. In essence, the \u00a0Reon Pocket Pro\u00a0 is a portable thermal device designed to cool or heat the area of the body it contacts, which is the upper back, just below the neck. It is definitely not a portable air conditioner but offers a unique approach to personal climate control.<\/p>\n <\/p>\n How Does It Work?<\/strong> The device has two independent thermal modules at its rear that alternate between cooling and heating based on the selected settings. A small fan draws heat away from the body and releases it from the top, ensuring a steady sensation of comfort. As one thermal plate reaches the set temperature, it deactivates while the other takes over, allowing for a continuous feeling of coolness.<\/p>\n <\/p>\n How Do You Put It On?<\/strong> The device must be positioned with both plates against the skin while keeping the air vent slightly above the shirt\u2019s collar. There\u2019s a version for shirt-wearers, which includes an adapter. The device is designed to curve with the body’s natural shape and employs flexible tubes that fit snugly around the neck, remaining hidden underneath clothing. It’s subtle but noticeable.<\/p>\n <\/p>\n Is It Comfortable?<\/strong> Comfort varies. It\u2019s manageable when walking or sitting upright, despite weighing around 200 grams. However, if you recline or lie down, it becomes challenging to wear. Noise is not an issue; even while typing at my desk, I hardly noticed the fan.<\/p>\n <\/p>\n Yet, I found the size somewhat cumbersome, and locating the right position proved tricky. Unlike a quick, on-off accessory, this device requires precise placement for effectiveness.<\/p>\n <\/p>\n Does It Cool?<\/strong> The Reon Pocket Pro operates in two modes: manual and automatic. In manual mode, users can set their desired temperature, while in automatic mode, it combines ambient temperature data via a small accessory known as the Reon Pocket Tag to determine optimal conditions. However, the sensor tends to work best in outdoor settings; when tucked into a pocket, accuracy may diminish.<\/p>\n <\/p>\n Upon first wearing the device, the cooling sensation near the neck begins almost instantly. As time progresses, thanks to the alternating thermal modules, the feeling of coolness remains consistent. Indeed, it cools, but the effect is localized\u2014the area directly beneath the device feels chilled, akin to placing an ice pack against your back. In heating mode, it offers a warm, comfy feeling reminiscent of therapeutic heat pads.<\/p>\n <\/p>\n Battery Life<\/strong> is a crucial factor. When set to a medium cool temperature, the device lasts nearly a full day, which is sufficient for a typical workday. However, higher temperatures will drain battery life faster. While using heat mode consumes more power, it\u2019s not a feature I tested extensively during my review days. Charging takes roughly three hours.<\/p>\n <\/p>\n Conclusion:<\/strong> While the \u00a0Reon Pocket Pro\u00a0 provides an immediate cooling sensation that can be delightful, it does not entirely eliminate the discomfort of heat. The upper back remains cool, but other areas of the body are still exposed to the relentless sun and high temperatures. The device can enhance comfort when combined with a fan, yet its localized cooling action may not suffice for everyone. Priced at \u20ac229, it poses a financial consideration and may be best suited for environments where temperatures frequently climb uncomfortably high, such as overly warm offices or crowded public transport. Overall, it has innovative potential, but it often falls short of completely replacing traditional cooling methods like air conditioning.<\/p>\n * Prices may have changed since the last review<\/p>\n<\/div>\n Images | Xataka<\/p>\n For more on staying cool this summer without relying on air conditioning, check out this insightful article by Xataka: According to this doctor, 30 seconds is all you need to stay cool during summer without air conditioning.<\/a><\/p>\n![\"Thermal](\"https:\/\/teknomers.com\/en\/wp-content\/uploads\/2025\/06\/1750631739_101_Facing-the-heat-of-Cordoba-in-the-summer-is-impossible.jpeg\")
