For those tram owners who have already installed private charging piles, portable charging guns may not seem so necessary. At least, this was my previous thought. It was not until that hot summer vacation that my best friend drove her AIONS Plus to Guizhou to escape the heat. While staying at the farm stay, she took out her original portable charging gun from the car, plugged it into the household socket of the farm stay, and began to charge the car. Although the charging speed is not as fast as that of a charging pile, only 13A, it is definitely a good emergency solution in an emergency. 

Seeing this scene, my heart stirred. So, after the Mid-Autumn Festival, I exchanged the points on the APP for an original portable charging gun. To ensure the safety of charging, I also bought a grounding socket. After all, not all household sockets are grounded. Considering that my dad's summer retreat is on the third floor, I chose a grounding device with a 15-meter-long wire. 

The Grounding Treasure doesn't come with a matching storage bag. To prevent the 15-meter-long wire from getting tangled up, I bought another storage bag on Taobao. When I showed it to my best friend, she also thought this storage bag was very practical, so she bought one of the same style as well. 

Many things are like this. They may not be needed in daily life, but once they are needed, they can play a huge role. A portable charging gun is such an item. What do you think?
