Stable power output
Voltage stabilization function: The portable power station is equipped with a voltage stabilization circuit to ensure stable output voltage. For example, when the battery power changes or the load changes, the output voltage can be stabilized within a range such as 220V±5%, meeting the requirements of most devices for stable voltage.
Frequency stabilization function: Through the built-in control circuit, the frequency of the output AC power is stabilized at 50Hz or 60Hz, which is consistent with the mains frequency, ensuring the normal operation of frequency-sensitive equipment, such as some precision electronic instruments, motors, etc.
Fast switching time: High-quality portable power stations are equipped with fast-response switching circuits. When the mains power is interrupted, it can complete the switch from the mains power to the energy storage power output in a very short time (usually between tens of milliseconds and hundreds of milliseconds). This speed can ensure that most devices will not fail or lose data due to short power outages, thereby realizing the function of uninterrupted power supply.
Reliable battery performance
High energy density: High-performance lithium batteries, such as lithium iron phosphate or ternary lithium batteries, have high energy density and can store a large amount of electrical energy in a small volume and weight, providing power support for a long time for the load. For example, some large-capacity portable energy storage power supplies can power equipment for several hours or even dozens of hours under full load.
Voltage stability: The output voltage of lead-acid batteries is relatively stable, and the change of its terminal voltage is relatively gentle during the discharge process. At the same time, the lead-acid batteries in portable power stations are usually equipped with voltage stabilization circuits, which can stabilize the output voltage within the range required by the equipment, generally 220V±10%, ensuring that the connected equipment can obtain a stable voltage supply and avoid damage to the equipment due to voltage fluctuations.
Long cycle life: The battery has been carefully designed and quality controlled, has a long cycle life, can withstand multiple charge and discharge cycles without significantly reducing performance, and ensures long-term reliability when used as a UPS.
Safety protection: Equipped with a complete battery management system (BMS), it has overcharge protection, over-discharge protection, over-temperature protection, short-circuit protection and other functions to ensure that the battery operates in a safe state, prevent safety accidents caused by battery failure, and extend the battery life.
Multiple output interfaces: In order to meet the power supply needs of different devices, portable energy storage power supplies are usually equipped with multiple output interfaces, such as AC sockets, DC output interfaces, USB interfaces, etc. This allows it to power multiple devices at the same time, such as computers, routers, mobile phones, emergency lighting equipment, etc., and provide power protection for various key equipment when the city power is interrupted, realizing a multi-device power supply function similar to UPS in different application scenarios.
