Description

Technical Field

[0001] This utility model relates to the field of mobile power charger technology, specifically a mobile power charger. Background Technology

[0002] Portable power banks store electrical energy in their internal batteries, allowing them to charge other devices when needed. Common portable power banks range in capacity from several thousand to tens of thousands of milliamp-hours, providing multiple charges for devices such as mobile phones and tablets. They charge various USB-enabled devices, such as mobile phones, tablets, Bluetooth headsets, and cameras, via USB or other charging ports. Some portable power banks also support fast charging technology, allowing devices to charge more quickly and continue to be used. Using portable power banks eliminates worries about battery life, enabling users to use electronic devices more freely and improving the convenience and comfort of their lives.

[0003] When a power bank charger charges electronic devices such as mobile phones and tablets, there is resistance loss as current flows through the circuit. This resistance loss is released as heat, causing the power bank to heat up. At the same time, the heat from the power bank may also be conducted to the mobile phone, causing the phone to heat up or even become hot. In severe cases, this may cause the power bank or the mobile phone to catch fire, resulting in a fire accident, which is quite dangerous. To address this issue, we have provided a power bank charger to solve the above problems. Utility Model Content
