Technical Field

[0001] The utility model relates to the field of electrical equipment, in particular to a portable direct current uninterruptible power supply. Background Art

[0002] A DC uninterruptible power supply is a power supply device used to provide a continuous and stable supply of DC power in the event of a power grid interruption or failure. DC uninterruptible power supplies are widely used in key equipment or systems that require continuous power support, such as communication base stations, data centers, medical equipment, industrial automation, etc. They can provide reliable power protection in the event of a power grid failure or power outage, ensuring the normal operation of the equipment and preventing data loss or production interruptions.
