Description
technical field [0001] The invention relates to the technical field of portable charging equipment, in particular to a power bank that prevents USB terminals from falling off. Background technique [0002] Charging treasure, also called mobile power. A portable charger integrating power supply and charging functions, which can charge mobile phones, tablet computers and other digital devices anytime and anywhere. Generally, lithium batteries (or dry batteries, less common) are used as power storage units, which are convenient and quick to use. [0003] The core technology of the power bank lies in whether the curve of the discharge current and voltage is smooth when charging the mobile phone. It is closely related to the important technical indicators of whether it will damage the charging device. The discharge curve test must refer to the third-party authoritative test report. [0004] For mobile power, it has a certain emergency function. In the case of many digital power...
