Portable air pump are emergency equipment, usually used to small or SUV mid cars. For large cars (e.g.: pickup trucks,vans, and RVs.), the inflating speed is relatively slow and the battery consumption is fast. This is normal.

A screen protector is attached to the product when it leaves the factory. When you receive the product, you will find that there is a layer of screen protector on it, if it is not necessary, please do not tear off the protector.
