Product Information

Silicone material allows you to adjust the airflow direction to the most comfortable angle for you. An exclusive air duct is adopted for the first time, and a three-dimensional wind can be realized from 360 ° vertical direction ( Patented vertical ventilation). Extremely powerful for an intense cooling experience

Because other folks have mentioned the weak point of where you plug it in, I try to be careful and gentle when plugging and unplugging it. Bladed fans operate with a stronger airflow due to the open-blade design. Fans with bladeless designs run with small turbines, and the cold air exits through small air outlets, but there are powerful bladeless models with 4 turbines.Portable coolers are designed to be easily portable and used outdoors. For this purpose, they require an internal and autonomous power supply. They are battery-operated and are usually powered by rechargeable batteries.

The battery capacity varies from 2000 to 6000 mAh. If you plan to use the portable cooler for a whole day, you should fully charge the battery. This usually takes 3-4 hours. If there is a possibility to replace the battery, take a few more fully charged batteries with you – just in case. Of course, there were moments when the heat was just unbearable, and that's when I cranked up the fan to its maximum speed. The relief it provided was instantaneous, cooling me down and making those sweltering moments much more manageable.As you can see in the pictures – the major difference is regarding the blades. The bladed fans have visible blades, while the bladeless don’t. They operate with turbines hidden inside the body.
