Thanks for sharing! From my personal experience, Coolify 2s is suitable for long time use and the overall performance is more balanced. Coolify 3 is more suitable for the scenarios where you need to cool down quickly, but the battery life will be a bit shorter than Coolify 2s. So, if you are travelling outdoors, 2s is more recommended, if you are doing outdoor sports, 3 is more recommended!
USELESS PRODUCT!！ Neck Air Conditioner: This product, to be precise, should be a useless product except the fan. One question, do you turn on the air conditioner and open the doors and windows at the same time? Obviously not! This is equivalent to turn on the air conditioner under thousands of watts of solar heat, which is obviously very unsuitable for outdoor use and ridiculous. Once it reaches 91.4 F, the ambient temperature will be directed back into the machine through the iron pieces, This will cause the wind it blows out to be hot air. The wind making you even hotter. This is the principle of Physics, so this product is useless from the beginning. And this product is very heavy. You have to carry it when the battery is out, which is a burden.
