With the development of economy, people's demand for electricity is increasing. The harm caused by natural disasters to human society is often shocking, and most people have had a deep experience. In the face of emergency rescue operations after natural disasters, portable emergency power supplies are particularly important.

The portable emergency power supply is an emergency power supply that inverts DC power into AC power, which is composed of chargers, inverters, storage batteries, isolation transformers, switch switches and other devices. Mainly used for outdoor office, field photography, outdoor construction, backup power supply, emergency power supply, fire rescue, disaster relief, car start digital charging, etc.

Take the recent typhoon "Mangkhut" as an example. "Typhoon Mangkhut" is known as the most powerful typhoon in recent years. At the same time, it is also called the king of wind by all walks of life. Waterlogging and power outages have occurred in the areas encountered by the typhoon, which is harmful to people's lives and property. The damage caused is also very serious. It is impossible to go out under the power outage, and even eating has become a major problem. Portable emergency power supply plays an important role, such as powering electric fans, TV sets, and rice cookers to ensure basic life at home. Not affected.

In the face of emergency rescue after a typhoon, in order to ensure the fastest repair and restoration of power supply after a disaster occurs, portable emergency power supplies have become a special landscape for emergency repairs. In more severely affected areas, portable emergency power supplies have also played an important role in temporarily solving power supply problems.

Types of commonly used portable emergency power supplies:

1.  Portable Power Station: an emergency power supply that inverts DC power into AC power, which is composed of chargers, inverters, batteries, isolation transformers, switch switches and other devices. It is suitable for loads that allow interruption of power supply for more than 0.25s.

2. UPS uninterruptible power supply: It is mainly composed of power converter energy storage device (battery) and switch (electronic and mechanical) to ensure the continuity of power supply static AC uninterruptible power supply device. It is suitable for loads with millisecond-level interruption of power supply.

3. Self-provided emergency diesel generator set: It is a power generation equipment composed of a diesel engine that drives a power frequency AC synchronous generator. The quick and self-starting generator set is suitable for buildings where the power supply interruption time is more than 15s. The working time of the emergency power supply should be considered in accordance with the power outage time allowed in the production technology. When used in conjunction with an automatically-started generator set, it should not be less than 10min.
