Buying a portable power station mainly considers the following aspects:
1. Battery capacity: It is recommended to choose a large-capacity portable power station to avoid repeated charging.
2. Output power: When buying a power supply, you must know the power or battery capacity of the equipment to be loaded, so as to know which power supply to buy and whether it can be driven.
3. Cells: The main consideration when buying a power supply is also the cells. The cells can realize overcurrent protection, overcharge protection, overdischarge protection, short circuit protection, overpower protection, overtemperature protection, etc. Good cells have long life and performance. Stable and safe.
4. Charging method: When the power supply is idle, the charging method of the power supply: the general power supply has three charging methods: mains, car charger, and solar panel charging. You can choose according to your needs.
5. Diversity of output functions: select AC, DC, car charging port, DC round port, USB, Type-C fast charging, wireless charging, lighting and other functions according to your needs.
Is a portable power station necessary?
Compared with the ordinary mobile power supply, the biggest feature of the portable power station is that it supports 220V AC power. The high-power portable power station is not a problem for outdoor camping and cooking, and it can even charge electric vehicles. It is a fully functional and Powerful portable "power station". Of course, in the home scenario, in the case of temporary power outages or sudden power outages, the portable power station can output continuous and stable power to maintain the normal power consumption of the equipment, and lighting, cooking, and office work are not a problem.
Advantages of STW portable power station
