In recent years, camping in China has evolved from a niche outdoor sport to a popular leisure activity across the country, becoming the 'poetry and distance at the doorstep' of countless tourists.

Far from the hustle and bustle of the city, a brief journey of slow paced life has become a choice for many people for leisure and entertainment. Living in a camping site, many people choose camping facilities such as picnic tables, cooking utensils, lighting, communication, etc. This outdoor home requires external power supply to support a large amount of outdoor electricity consumption. Outdoor power sources play a very important role, and with the increasing demand, the demand for portable energy storage power sources is increasing.

How do we choose outdoor energy storage batteries?

1、 Working principle

Portable outdoor energy storage power supply is an outdoor emergency power supply composed of chargers, inverters, batteries, isolation transformers, switching switches, BMS, and other devices that convert direct current energy into alternating current energy.

The portable energy storage power supply consists of a set of AC+DC charging+AC and DC inverters. When the public power supply is normal, the battery in the portable outdoor energy storage is in a charged state. Once the main power supply is interrupted, the battery immediately outputs the stored DC power to the inverter and converts it into AC power to wait for startup to charge the device. Under normal circumstances, the time the battery maintains power will be determined based on the power of the electrical equipment used.

2、 Power and battery capacity

When choosing outdoor energy storage batteries, you should remember two knowledge points: W (watts) and Wh (watt hours).

The unit of power is W (watts), and the unit of capacity is Wh (watt hours). Simply put, the former determines what kind of electrical appliances can be used, while the latter determines how long they can be used.

When we are camping outdoors, we need electric cookers, Induction cooking, barbecue ovens, electric hotpots, small fans and other appliances. To support the use of these appliances, we need outdoor power supply of about 1000W and battery capacity of 600-800Wh.
