Description

Technical Field

[0001] The utility model relates to the technical field of chargers, in particular to a battery charger with storable cables. Background Art

[0002] As battery-powered electrical devices become increasingly diverse and portable electrical devices increase in number, the market demand for battery chargers for portable electrical devices is also growing. In order to solve the problem of portable charging of batteries for portable electrical devices, the prior art proposes a portable charging device that provides a charging interface, a charging cable, and a transformer that converts power sources of other voltages into the voltage required for charging. However, the existing battery chargers have long charging cables and large plugs, which are not easy to store or need to be wrapped in a storage compartment when stored. This method may cause the following problems:

[0003] 1. Tangle and knot: Charging cables are prone to tangling and knotting when they are wound. This can result in extra time spent untangling the charging cable when it is time to use it.

[0004] 2. Cable damage: Repeated winding and unwinding may cause damage to the charging cable, especially at the connector and cable interface. Frequent bending and twisting may cause damage to the metal wire or insulation layer inside the cable, ultimately affecting the performance of the charging cable.

[0005] 3. Bending and breaking: Charging cables may be bent frequently during winding and unwinding, which may cause the cable's flexibility to weaken and even break in some cases.

[0006] 4. Connector damage: The connector of the charging cable may be damaged due to frequent plugging and unplugging. If the cable is frequently wound and unwound, the stability and durability of the connector may be weakened, eventually leading to contact problems or failure to charge properly.
