Description

technical field [0001] The present invention relates to a kind of back-up power supply equipment, more specifically, relates to a kind of mobile phone back-up power supply equipment. Background technique [0002] What general mobile phone adopts is that special main battery (generally lithium-ion battery) provides power to mobile phone, when main battery power is insufficient, needs to utilize 220V alternating current to charge main battery by mobile phone charger. Due to the limited power of the main battery of the mobile phone, the user needs to keep the mobile phone for continuous calls, so he will carry the mobile phone charger with him and charge the mobile phone under an environment with a 220-volt AC power supply. This mode will be extremely inconvenient to the user away from home. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a backup power supply device for a mobile phone, which can supply power to th...
