Review on 💨 TORRAS Coolify Portable Air Conditioner Neck Fan, Hands-Free Semiconductor Cooling Bladeless Fan, 4000 mAh Rechargeable Leafless Mini USB Fan for Outdoor Home Office, 3 Speeds, Brilliant Black - Enhanced SEO by Jessica Hill

I work as a postal worker in California and the days are quite hot, I tried this product. It didn't impress me. I would say that it is not intended for continuous use in hot conditions. I had it fully charged and it lasted about 2 hours at maximum fan speed. It got chilly, but after a while the cooling stopped cutting off. The device will emit 1 beep. I will send it back as it is not worth 160€. Update, I'm still considering returning it but I've used it at medium power and it's lasted longer. And it cools more efficiently. Expect more updates. Update 2 I decided to leave, it works fine at medium power and lasts about 4 hours. It brings relief when it's hot. But to be honest it doesn't work very well on 104 and above.
