A plurality of hollow holes are provided on the surface of the protective device. The hollow holes are used for viewing the display screen 6 of the portable AC charging pile and pressing the button 7. The hollow holes can be adaptively changed when the protective device is deformed. The owner can see the display screen 6 and button 7 on the wrapped portable AC charging pile 5 through the hollow holes, so that it is convenient for the owner to operate the button 7 through the hollow holes.

[0035] The tubular protective cover 1 is integrally formed with an elastic material, and the elastic material can be a material with high elasticity, wear resistance, temperature resistance, and weather resistance, such as silicone and rubber. When the tubular protective cover 1 is made of silicone material, the elongation of the selected silicone material should be between 150% and 1000%, so that when stretched by external force, the silicone material can effectively extend within this range without breaking, thereby ensuring that the protective device can wrap a portable AC charging pile 5 that is 10 times larger than its own volume, thereby meeting the needs of portable AC charging piles 5 of various shapes and sizes on the market, and better fitting the outer surface of the portable AC charging pile 5.

[0036] The hollow holes on the protection device are in the shape of a triangle, a strip, or a circle, or a combination thereof.
