I have tried a few neck fans, two $30 options and this Torras Coolify Cyber. There is a huge difference! USE: The Torras is able to actually cool the air before it is blown both up and down your neck. The addition of the cooling pads (sides and rear) is also amazing. In 95f+ Texas heat and humidity I has feeling a difference. My body was hot, my skin felt the heat of the sun, however, with my neck being cool I have been able to be outside more doing the things I love (the neck/base of the skull is the thermostate of the body). BATTERY: I can get a few hours of use using the cooling pads and <30% fans. I don’t feel the need to turn the fans above 60%. Best noise to cooling. This has been enough for my use and the charging speed is plenty quick. If you need more time, carry a battery pack that can output a minimum of 15w Type C. APP: I did not expect to use the app at all. Why would you need an app to use this? The short answer is, you don’t need to use the app, which is great. I did find the app useful to set the fans to about 5% with the cooling pads on. This is a nearly silent setup and very effective cooling. Something I tested but have not used in practice is the fact that this can also heat! I will put the heat to the test this winter and happy that this can do both. I will be flying with this later this month, looking forward to beating the hot airplane! VERDICT: I have already recommended this to friends and have to keep it away from my teenage son. If you are the fence, consider this an investment in your wellbeing as it will enable you to be outside more!

I love this gadget, it definitely delivers on cooling you off. The charge on it lasts me about 1.5 to 2 hours depending on if I run it on high speeds or not. The app is simple and informative. It does provide heat as well but I have not used it, as I am hot natured. Very sleek design and comes with a nice sturdy carrying case for protection when not in use. Will purchase again and feel it would make a great gift.

This portable unit is a very unique product that does indeed provide refrigerated quality air and with a switch turn to heating. It is very pricy so keep in mind that sometimes it really is just too hot outside so it might feel like it’s not working.

COOLiFY Cyber is a revolution in personal air conditioning! Unlike typical neck fans, it offers powerful cooling with customizable airflow (Cool/Fan/Heat) thanks to its KU 3.0 chip and graphene tech. Lightweight and compact, it’s perfect for outdoor activities. Highly recommend for ultimate comfort!

This wearable air conditioner/heater has contact pads that heat or cool your neck really well where it touches your skin. It also has fan outlets aiming up toward your face and both up and down the back of your neck to help keep you comfortable. It charges fast, has long battery life and is relatively quiet when operating. You can even use it while it’s charging which is a great way to extend its use by having it connected to a large battery in your pocket or bag. Highlights: * Fast heating/cooling. * Relatively quiet when fans are running. * Nice on-unit displays to show power level, battery status and which areas are being heated/cooled. * Includes a right-angle charging cable for better cable management during both use and charging. * Long run times (2-3hrs for cool, 3.5-4.5 for heat, 7-13 for fan only). * Very fast 20W charging speeds (0-80% in 1.2hrs). Room for Improvement: * A tad heavy at 1lb 2oz (1/2 kg). * All displays only visible when not being worn. * Buttons are hard to locate by touch without looking while wearing. * No significant way of determining modes or status while wearing. * Must use app for anything other than basic heating/cooling/fan. Setup: Basic stuff. The neckband comes with a right angle USB-C to C charging cable and no USB adapter. You can use just about any other compatible cable and any suitable power adapter. Plug the right-angle end into the bottom of the neckband and the other end into a 20W or higher USB charger for the fastest charging speeds. It will also charge from lower-powered adapters, but will take longer. While charging, the display on the side above the connector indicates the current charge status. When done, unplug the cable and you’re good to go, or if the cable is long enough or the power source is portable, leave it plugged in and start wearing it run off the external power source. Usage: There are two buttons on the neckband to control the basic features. The Mode button works even before you turn it on so that it will come on at your preferred mode of cool, heat or fan. The selected mode is represented by the color of the icon in the display on the side above the buttons (green for fan only, blue for cool and orange for heat) and the number represents the power level from 0 to 100% power. The power button turns the unit on or off and cycles through 3 pre-set power levels. When on, the display above the charge connector shows the current battery level. Both displays turn off after a few seconds but you can “wake” them up with a quick tap of the power button. The fans come on immediately and the heating/cooling plates get to their desired temperature quickly. You can optionally install the free iOS or Android app to do even more with the settings. With the app, you can control the fans and the temperature contact plates independently, turn on Auto mode, set a favorite heating/cooling mode, set an auto-off timer, update the band’s firmware, etc. The app connects with the neckband quickly and consistently without needing to be paired (BTLE). Once you change the mode settings of the connected neckband, you can disconnect the app - it doesn’t need to remain running for the set mode to continue. Even though the band is kinda heavy (over a pound), it is well-balanced and relatively comfortable to wear for long periods of time. As mentioned above, once it’s one and being worn, you can’t see the displays and it’s not easy to find the power and mode buttons. Best to set it up, then put it on, and if you need to check anything like power levels or mode, you need to take it off. There is a setting in the app labeled “Voice Prompt” which I had hoped would speak the current mode, power level and battery level while being worn, but all it does is enable or disable beeps when tapping buttons. The only differences in beeps is a double-beep when turning it off. Everything else does the same single beep. Overall: Amazing cooling and heating performance. Quick charging and long run times. Comfortable to wear and mostly easy to use. The app expands functionality with more modes and flexibility. My few suggestions for improvement would just make it that much easier to use once it’s being worn. Otherwise, a great way to maintain your cool (or get warmed up) without adjusting the room’s temp or the amount of clothes you have on ;-).
