AICE Lite Plus Neck Air Conditioner

I'm not able to find any information about this message. It appears to be an error, but it's vague and the app does not have anything that helps to debug it. I'm upset because out of the box, this seemed really promising and useful. It worked for the first few weeks. I barely got to use it, but now it won't activate heating or cooling for more than a moment before it flashes "E2". Only the fan works. I have tried resetting it, but the error always returns.

I've reached out to the customer support. We'll see if they can diagnose it. I wish I had more information on the error without needing to contact them but there isn't even a manual with detailed information.

Ok this review is only after 30 minutes of use but so far I'm rather impressed! It is cooling me so much that I only have it on minimal fan speed now. On full fan speed it is quite a noise pass your ears but on low speed quite acceptable.

i was a skeptic, but after trying it i was sold works great on my walks in the HK and Thailand heat. would definitely recommend to anyone. noise level is not to bad took very little time to charge, size is a little bulky but not terrible i still give it 5 stars

I must admit - I wasn't sure about spending so much on something that I wasn't too sure about, but I took the plunge and I have to say that I'm really impressed. I don't live anywhere exotic, just good old Blighty but some of the summer days are just too hot and stuffy - no a/c in our houses to cool off. The AICE lite 2025 really cools you down with true cold plates on the neck and cool air blowing up to cool the head - it really does work like they say! I've tested the heat setting - this seems really effective too.
The size and weight are fine - you can barely tell you're wearing it. other than being cooled down :-) I was really surprised at how quiet the fans are, you can hear the wind pass your ears but the fans themselves are really quiet.
The app gives great control over the fan / heat / cool settings and seamlessly connects - so simple to use.
Really worth the money, can't recommend highly enough!

Having used the 2024 model extensively I didn’t hesitate to purchase the new model upon release.
The AICE lite 2025 has much improved cooling, heating and a noticeable increase in battery life.
The 2024 model was very impressive and helped to keep me cool during my travels and was a saviour over the winter months to keep the neck warm.
The new 2025 model is almost identical to the 2024 model but now has improved circulation and cooling down the back.
Still maintains its superior build and quality over cheaper alternatives.
If you’re in the market for a neck cooler, hands down these must be the best out there.
It may not be to everyone’s taste or budget but if you want something that just works and works well this is a must have item.
Do not be put off by the size as once you wear it you forget it’s there!
Once again Ranvoo has released an excellent device with huge improvements over the last model (which is still a worthy purchase).
I would highly recommend one.

As a frequent business traveler, I’m pretty picky about portability and weight. Before heading to Indonesia, I stumbled upon the AICE LITE on YouTube and decided to grab this upgraded version. With only 5 days left before my trip, I was worried about shipping, but the official site came through—delivered in just 3 days. After a week of using it in Indonesia’s brutal heat and sticky humidity, I’ve got to say, this thing is a game-changer. I never tried the older model, but this upgraded one is legit. Even on lower settings, it keeps me cool without breaking a sweat. Crank it up to max, and yeah, the battery takes a hit, but no big deal—it works while charging, and paired with my trusty power bank, I’m covered all day. Hands down, this is a must-have for anyone grinding in hot climates. No fluff, just straight-up relief.

I spent a long time researching and comparing products from other brands before finally deciding on the AICE Lite. To be honest, the price is slightly higher than that of regular fans. However, considering the added cooling feature, smartphone control, and other functions, I found this product to have the best value for money among similar options.

The overall design is also much cooler. When I wear it, I not only want to feel comfortable but also want others to notice it. As a tech enthusiast, that might be why I like it so much!

I have to say, this neck ac is the best I’ve ever used! I’ve bought regular fans before, but they always felt like the wind wasn’t strong enough, and when I’m outdoors, the air is just hot anyway. ice lite completely changed my perspective. The cooling pad that touches your neck feels like having an ice pack—it’s so refreshing! It’s perfect for me since I work outdoors wearing a helmet and safety vest.

The fan is also super lightweight, so I keep it around my neck all the time, even when I don’t need it. When I do, I just press the button, and within seconds, I feel comfortable again. The AI mode is a game-changer—it makes the battery life last an entire day, even though I’m not using it on full power the whole time.

Overall, I really love this product! I might even try the AICE 3 or other RANVOO products in the future

C'est définitivement pas fiable, il est tombé en panne dès la première utilisation

First and foremost, I love this product. It has made Oklahoma summers more manageable. However, the power button came off my unit, and while i can make it function, I would prefer the button in place. I have written two separate emails to them and received no answers.

This has a unit inside that creates cold and it is not a fan that just roatates hot air. This saved me when I was in the desert with tempatures well over 100 degrees. I was so thankful I had this around my neck.

I used Coolify 2, Coolify 3 it's not satisfy me, I got AICE LITE it's a lots better than old one. new firmware got C4 speed, nice approvement. thanks ranvoo

* Removed a star for the website that's very hard to use, especially the currency dropdown keeps switching
* Removed a star for how long it took to ship and get delivered... 2 weeks!
* Removed a star because they gave me a reward in the form of online coupon toward an electric toothbrush (I could have elected a pouch instead) but then when I try to use it, it never applies to my cart.
* Removed a star given how bulky the gadget is. It's also very hard to turn off.

Very good device. Makes practically no noise. Recharges very quickly and lasts a long time in use. Quality product, solid and efficient.

Got to admit this has been an amazing additional to the fight against both heat and the cold.

For an Wheelchair user this simple device is an amazing piece of kit. It can be so easy to either overheat or chill to the bone in a wheelchair and having this around your neck gives that instant relief when it is needed.

Had it for less than a month before it stopped working the cooling/heating mode with a vague error "E2". There is no information online and in the app about what this means. Also, I registered for the warranty, but there is no information on how to exchange a faulty device for a replacement. There is a "return" option, but it looks like they force you to pay for the return.

TL/DR: Device was faulty after light use, the app/website have no helpful information, and the customer service seems to run in circles.

So far, I’m loving the neck air conditioner. Just bought another as a gift

Very lightweight wonderful device wonderful in the restaurant industry

I was hanging out with some friends outside in the 95 degree heat a couple weeks back, and while I at first felt a little silly putting on a neck fan, the cool air it was blasting at me made it all worth it. And other people were saying things like "I should have brought one of those", which made it feel even better 🤣🤣

I haven't run the battery from 100% to 0% yet in a single usage, but after about 2 hours of wearing it, I think the charge went down by about 2/3. Overall I think that's a pretty respectable battery life. I'm looking forward to using this thing more in the future, as the weather just keeps getting warmer and warmer!

Disappointed that to get instructions i had to download App. Not everyone wants to download every app. It should have come with compehensive instructions particularly considering the cost.
I have a much cheaper neck fan which seems to work well in most situations
Not sure your product is worth the extra money
Maybe if I had proper instructions I would have a different view

The air temperature emitting from the device isn't affected much, it is still ultimately a neck fan, but with a pad all around that gets warm/cold. I had hoped for a gentle stream of warm air on heat mode or for some cooler air on chill mode.
It works, it does a good job, but buy it knowing the wind from the fan is only room temperature and isn't chilled much. The greatest effect comes from the cooling sides, which are good.
