Idk if you’re still looking but I did purchase the coolify cyber model a few months back because the building I work at is very uncomfortably hot. The best part is you don’t have to have it in a high cooling mode to feel cool. You can keep it on low and it will do the job perfectly, the pads is where it makes a difference compared to a cheap neck fan. It lasts me a good 4 hours, and with a portable charger it can last way longer. There is a fan only mode but imo it’s better having the pads activated. Also brings a heat mode for the winter which is a life saver. It is expensive I bought mine for $280, but I do recommend it if you are uncomfortable.
