RANVOO2024 [No.1 Coolest & Most Portable] AICE LITE Neck Air Conditioner, Ultimate Immersive Cooling 6,000 mAh Rechargeable Neck Fan Personal Cooling Device Gift that Blow Cold Air, White

The AICE Lite is a well built piece of kit. It feels weighty and solid. No creaky plastic here. The display is crisp , simple and well designed. The packaging provides a nice unboxing experience and a nice presentation, with a die cut inner flap that reveals the device while also pointing out controls and vents. It all feels of quality and a premium experience. The box contains the neck cooler and a charge cord. No charge brick, no instructions.Full disclosure, I’m a fat guy living in South Florida. Worse, I work in a non air conditioned warehouse in Miami. It’s hot. It’s uncomfortable. You can understand why I wanted to try the AICE Lite. So does wearing this keep me cool at work? Well, no. But it helps. In extreme situations like mine, it won’t keep you cool, but will help somewhat. Maybe Ranvoo can make some companion devices. Maybe this device combined with an air-conditioned hat, underwear and shoes would keep me comfortable. ;-)In the morning, while temperatures are in the low 80s, the AICE Lite feels cold and refreshing. But in the afternoon when the temps climb to the upper 80’s and 90s, the unit is overwhelmed. I’ve read reviews that say that the cooling plates get warm under these conditions. That is how it feels, but the unit is still cooling. If you turn the unit off, you’ll quickly find that you were being cooled. In really hot situations, you’re still going to sweat. So if your plan was to use this to keep you cool and fresh while you’re walking around Disney World in August, well….I’ll still use the AICE Lite at work during the hottest months. But the real surprise is how useful it’s been around the house. It quickly cools you down when you get hot doing chores or after a hot shower. It’s great if you’re standing over a hot stove. As I write this, I’m using it for soothing heat around my sore neck.There are 4 modes: cooling, heating, fan only and an AI mode. The AI mode is a thermostat mode that works like any other thermostat you have. The AI mode is the mode to use, in my opinion. I found I could use it as a set-and-forget mode that kept me comfortable without freezing my neck. No constant fiddling. At my work during the morning, it cycled on and off as needed but by the afternoon it ran fast and constantly, trying to keep up.The battery lasted me three and a half hours on AI mode. So to cover an eight hour day, I needed to connect it to a power brick I carried in my pocket.One of my concerns was whether I would look silly wearing a neck air-conditioner. What I’ve found is that almost everyone ignores it, much as they would a pair of headphones resting around your neck.The AICE Lite is easy to operate by itself, but pairing it with the free Metaura app adds some functionality. This includes being able to make adjustments while you’re wearing the unit and can’t see the unit’s display. While you have simple low, medium, high settings on the unit, you don’t on the app. The app instead has you set a temperature. The app also gives you a low power mode, a silent mode, a cooling first mode and a hot pack mode. The trouble is that there are no instructions for the app. And I don’t see a difference between the heat mode and the hot pack mode. Same thing with the cooling first and cooling modes.A few things I think I have figured out: The low power mode seems to reduce power to the cooling/heating plates. The quiet mode just reduces the fan speed. The app displays the ambient temperature. This is often higher than the room temperature when the unit is sitting on you. When the app is connected, you can’t turn the unit off with its power button. Instead it goes into a sort of standby that’s shown by a pulsing power light. You have to use the app to turn it completely off.So my wish list for this neck A/C is full instructions for the app explaining the more obscure settings. I’d also like some raised bumps on the physical buttons to make them easier to use by touch. And I’d like a gentle spring to help keep the units arms in contact with the side of my neck.Wish list aside, I’m glad I bought the AICE Lite. I had imagined a total solution for my hot working conditions. It’s not, but it does help, while also being surprisingly useful around the house and car. If you have realistic expectations, I recommend the AICE Lite.

This product is absolutely one of the best purchases I've made in years! I gave it 5 stars because I honestly feel like it's improved my quality of life at work, and in leisure and exercise! I wont say it's perfect in every regard, but I think it is well worth the money for the value and relief it can bring. I've had 2 different neck fans and found they were insanely practical for my normal every-day use, ESPECIALLY at my job! I work in and outside and the temperature can change pretty drastically some times. But with the Aice Lite, I love having the ability to just put a personal "air conditioner" around my neck where I can just push a button and have heat, cold or just a fan!I knew how this tech works for cooling before I bought it, but first time buyers should know that there is heat exhausted from the black metal vents on the sides when you have the "cooling" setting on. If you have long hair, you may want to keep it clear from the vents to keep yourself cool. (I have very short hair so I can't tell you anything about any possible hair entanglement issues)Pros:-light (heavier than my neck fans but still quite light on the neck)-premium materials (the metal plates are smooth and feel very comfortable against your skin at any temperature; the silicone on the hinge looks good; and the plastic feels premium and solid)-temp adjustable (with the free app you have a great deal of control for your exact preferred temp; without the app the +,- buttons have presets: low, med, high for each mode)-features like "low power" and "silent mode" to help save battery life and limit fan speed to reduce noise-good airflow along the cheeks and ears and it has rear downward facing fans. (The usefulness of this will depend on the kind of clothes you wear; I've found it to be very great for keeping the back of my shirts dry from sweat)-FAST (heat and cool modes both work very fast so it's perfect for when you're waiting for a car's heat or AC to start working!)Cons-battery life (you will want to be aware of your battery life when using this throughout the day and will almost always need to be charged at the end of the day if you want to use it without issue the next day; however the Aice Lite does allow you to charge it while it's in use at "low power" mode so if you have a portable battery bank with you, the included charging cable has a 90 degree connector that makes charging and wearing at the same time more comfortable and less likely to damage the charging port.)-crevices in and around the hinge can and will build up with hair, dry/dead skin and sweat. (The silicone keeps all that away from the internals of the device very well, but with so many crevices on the back it adds some unnecessary cleaning)-the screen seems like wasted "real estate" (a screen always facing away from the wearer has limited use; I like that it has a matte finish, it doesn't pick up fingerprints very well either, but maybe future revisions or products could have a smaller screen for showing battery/charging information?)-the blue color is priced higher than the white at the time of my purchase.Final VerdictThis is a great product that offers a versatile way to address personal comfort in a sleek and modern piece of wearable tech. It does it's best work inside, but it absolutely works outside too! I think there's lots of working people in all fields that would find something like this to be a huge benefit to making their lives more comfortable. This is certainly a pricier option in the "neck fans market," and I bought mine on a Prime Day sale, but for the quality of the product and the features it provides, I'd have felt happy with my purchase at full price too. (always nice to save money though!) On top of all that, after I bought and tried my Aice Lite I went to register the warranty and Ranvoo customer support reached out to ask for personal feedback for improvement! I feel very satisfied with my purchase!
