how long do portable power stations last when not used

　　Generally, batteries have a low self-discharge rate-however, when the equipment is not in use, all portable power stations have a shelf life of approximately 3-6 months when not in use. This is why it is recommended that even if you do not use portable power stations, it is best to charge them fully, preferably every two months. And store the device in a cooler place (room temperature is fine, but don’t store it for a long time).

　　A typical portable power station can last anywhere from three hours to 13 hours on a fully charged battery. The lifespan depends on the battery's age, type of battery, size, and the number of electronics used with the power station.

　　It’s important to note that if you plan to use portable power stations for emergency purposes only, it is recommended to charge them through a wall socket, AC power socket or car plug after 3-6 months, because when you use it, it will Slowly exhausted.

　　People are more and more caring for cars, and they are more and more knowledgeable about vehicle maintenance. Everyone will prepare some emergency vehicle maintenance tools on the car to make long-distance driving more at ease.

　　The basic parameters are roughly divided into several aspects: power, air output, additional functions.

　　There are single-cylinder and double-cylinder air pumps. This sounds a bit like the name of a car engine, but it's pretty much the same. Single-cylinder means that the tire pressure pump has only one power element inflating the tire, while dual-cylinder means that two power elements work at the same time.

　　So theoretically a two-cylinder is better. However, if the weight of some small cars is small and the tires are small, there is no problem at all with a single-cylinder inflator.

　　The air pump is divided into automatic and manual versions. As long as some pumps set the value that the tire pressure should reach, turn on the power, the air pump will automatically inflate the tire to the specified tire pressure and stop automatically. Of course, this type of inflator is also more expensive.

　　The inflator pump is used to inflate the car. Usually, when you can’t go to the auto repair shop in time, the environment you face may be more handheld automatic tire inflator.

　　Some air pumps will be carefully installed with lights to prevent night operation. And some tire pressure pumps also come with tools such as screwdrivers, pliers, etc., to give people many conveniences.

　　In the year 1824, a Swedish scientist named Jons Berzelius discovered this compound and told the whole world about its presence and significance. However, this was present in the world from the very inception of time, but the major fame came after it was discovered.

　　Another name for this compound is Silicon Dioxide, and its chemical identity is SiO2. As the chemical formula for this compound suggests, it is made up of atoms of oxygen and silicon. This can majorly be found in the sand all over the world. Many industries such as the pharmaceutical industry, food industry, and electrical industry use this compound to manufacture and finish their end products.

　　This compound, however, is not able to conduct electricity and has a melting point of 1713 Celsius. This is a compound and happens to be an oxide of Silicon primarily. It comes into existence by a chemical chain of reactions between oxygen and silicon atoms.
