Portable power station, also known as outdoor power supply, is a small energy storage device with built-in Lithium/Lead-acid batteries. It can provide a power supply system with stable AC/DC voltage output. It has the characteristics of large capacity, high power, safety and portability. Its battery capacity is generally 100Wh-3000Wh, equipped with AC input, DC input, AC output, USB/Type-C output and other interfaces. It is suitable for outdoor travel, outdoor work, emergency rescue, medical rescue and other scenarios.
Working principle of portable power station.
The portable power station consists of a control board, a battery pack, an inverter, and a BMS system. It can convert direct current (DC) into alternating current (AC) that can be used by other electrical appliances through an inverter. It also supports multiple interface DC outputs to charge various electrical equipment.
Life of portable power station.
The typical life of a portable energy storage power supply is about 300~2000 cycles.
The number of cycles is a unit used to indicate the life of portable energy storage power supplies. One cycle is calculated from charging from 0% to 100% and then discharging from 100% to 0%.
The life of portable energy storage power supplies is displayed in terms of the number of cycles, because the standard life of the same model varies depending on the conditions and environment of use.
Taking the Eagle portable energy storage power supply "Eg012Li" model as an example, its built-in battery is lithium iron phosphate,the number of cycles that can be used as a life indicator is "2000".If used every day, the estimated life is about 5.4 years. (2000 cycles/365 times ≈ 5.4 years)(Note: The estimated life is only an approximate reference value and will vary depending on the specific use environment and habits.)
How to choose a portable power station?
1. Select by battery capacity according to purpose
The battery capacity of portable energy storage power supply is expressed in Wh (watt-hour).
Wh is the amount of electricity consumed per hour. It can be judged that the larger the Wh, the larger the battery capacity, and the larger the capacity, the larger the battery size. You can choose the battery capacity according to the intended use.
2. Select by battery power according to purpose
Outdoor power supply can be compatible with low-power electrical appliances such as mainstream brand mobile phones, tablets, cameras, laptops, etc. on the market. It is recommended to use 100-300W low-power outdoor power supply for such appliances, which is more suitable for outdoor office or outdoor photography.
For outdoor camping and outdoor self-driving tours, if you want to have a comfortable outdoor travel experience like home, then the preparation of electrical appliances such as kettles, rice cookers, electric cookers, and car refrigerators is essential. Outdoor people with such travel needs are recommended to use outdoor power supplies with a power of 300-1000W.
If you just want to use it for lighting or to power some electronic devices, a low-power outdoor power supply can solve the problem. However, if you want to use it for common household electrical appliances such as refrigerators, induction cookers, air conditioners, etc. that require continuous power supply, you need to choose a high-power outdoor power supply. Here, 1000W-2000W outdoor power supplies are available, but the specific situation still depends on the actual family needs.
