When we go camping, we are afraid that the equipment will be out of power, inconvenient and insecure. We don't even have the opportunity to call for help in an emergency.

At this time, someone will say, isn’t it enough to bring a power bank? But the power bank is enough to fill the mobile phone three times at most. If you bring a drone, laptop, car refrigerator, rice cooker and other electronic products to camp, the power bank’s electricity is not enough, and it will not be used at all. Moreover, the quality of the current power banks on the market is uneven. The output current of poor quality power banks may be unstable, which will cause a certain degree of damage to the batteries of digital products. A few times have little effect, and frequent times may cause irreversible damage. Consequences.
