What does it mean to have bi-directional electricity from a portable power station? This is a question about portable power station technology, which many outdoor enthusiasts and electrical experts are interested in. In this post, I will describe the concept, principle, benefit, and application of bidirectional power supply for portable power stations, to help you better understand and operate portable power stations.
Outdoor power (Portable power station) is a built-in lithium-ion battery that stores energy and provides a multi-functional AC output. The device is lightweight, has a high capacity, is powerful, is portable, and can be used both indoors and outdoors. It can be utilized both inside and outside. It can be charged using either conventional or solar energy depending on the usage conditions. It can provide ultra-high-power 100-240V AC output and is equipped with a variety of DC output modules such as 5V/9V/12V, making it suitable not only for emergency car starting but also for emergency use of various types of loads such as power supply for consumer electronics and in-vehicle electrical appliances to provide reliable power supply security1.
The ability of a portable power station to output AC or DC power to power other devices as well as input AC or DC power to charge itself is referred to as a bidirectional power supply. Generally speaking, portable power station supports utility charging and solar charging, but some portable power station also supports car charging and Type-C charging, which is the embodiment of Bidirectional power supply2.
The principle of a two-way power supply of a portable power station is to use two devices, inverter and rectifier, to realize the conversion between AC and DC. The Inverter is a device that converts DC to AC and the Rectifier is a device that converts AC to DC. When a portable power station needs to output AC or DC to other devices, it needs to use an inverter or rectifier to regulate the low-voltage DC from the internal lithium-ion batteries to the desired high-voltage AC or DC of different sizes. When the portable power station needs to input AC or DC from other equipment, it needs to use a rectifier or inverter to regulate the external high-voltage AC or DC of different specifications into the required low-voltage DC of the internal lithium-ion battery3.
Outdoor power supply bidirectional power supply has the following advantages:
1. Strong compatibility: portable power station bi-directional power supply can be adapted to different input and output interfaces, whether it is the common AC socket, DC socket, USB socket, Type-C socket, etc. on the market, all of them can be connected and converted with the portable power station without the need to carry extra converters or adapters.
2. Fast charging and discharging: A bidirectional power supply for portable power stations can utilize high-power inverters and rectifiers to achieve fast charging and discharging. Generally speaking, outdoor power supplies that support bidirectional power supply can support fast charging protocols, such as PD, QC, etc., which can be filled or discharged for themselves or other devices in a short time.
3. High efficiency: Bidirectional power supply for portable power stations can reduce energy loss and heat dissipation problems. As the inverter and rectifier are integrated inside the body, problems such as line loss and poor contact can be avoided, while the optimized heat dissipation design can be used to keep the temperature stable, improving conversion efficiency and safety.
4. High Flexibility: Outdoor power bi-directional power supply can choose the appropriate charging and discharging methods according to different scenes and needs. Whether at home, in the car, or outdoors, you can find a suitable power source to charge the portable power station or supply power to other devices, without worrying about insufficient power or inconvenient charging.
1. Mobile office: Bidirectional power supply of a portable power station can provide stable power support for people in a mobile office, whether it is digital devices such as notebooks, tablets, cell phones, or office equipment such as printers, projectors, and so on, which can be charged and discharged by the portable power station. At the same time, the portable power station can also be charged by utility power, solar power, car charging, and other means to ensure the continuity and efficiency of the mobile office.
2. Outdoor leisure: Bidirectional power supply of portable power station can provide rich entertainment choices for outdoor leisure people, whether it is small home appliances such as stereo, lamps, fans, etc., or large home appliances such as refrigerators, kettle, microwave ovens, etc., all of them can be powered by the portable power station. Simultaneously, the portable power station can be charged via solar energy, car charging, and other methods to ensure the comfort and enjoyment of outdoor leisure.
3. Emergency Rescue: A portable power station's bidirectional power supply can provide reliable backup power for emergency rescue personnel, whether it's critical equipment like communication equipment, medical equipment, rescue equipment, or auxiliary equipment like lighting equipment, heating equipment, warning equipment, and so on. Simultaneously, the portable power station can be charged by utility power, solar energy, car charging, and other sources to ensure the effectiveness and timeliness of emergency rescue.
