Description

technical field [0001] The invention relates to a hand-held device, in particular to a hand-held power adapter. Background technique [0002] Handheld refers to a handheld terminal capable of data communication (Wi-Fi / GPRS / Bluetooth, etc.) with other devices. Most handheld devices are powered by a PMU (power management unit, power management unit). After the handheld device is turned on, the power management unit can meet the power demand of the handheld device. [0003] The handset is widely used in transportation, access control, logistics, etc. During use, it is necessary to ensure the normal power supply of the handset, otherwise it will easily cause a power outage, resulting in data loss. Contents of the invention [0004] In order to overcome the above-mentioned problems in the prior art, the present invention provides a handheld power adapter. [0005] The technical solution of the present invention is: a handheld power adapter, including: a protection circuit, a ...
