Spare battery charger for mobile phone {AUXILIARY BATTERY CHARGER FOR MOBILE PHONE}

The present invention relates to a secondary battery charger for a mobile phone, and more particularly, to a secondary battery charger for a mobile phone that can supply a charge of the secondary battery for the mobile phone and at the same time to the external electronic device.

Mobile phones are now indispensable for modern people. Such a mobile phone usually consists of a main body and a battery coupled to the main body to supply power required for the operation of the main body. Mobile phone users usually have one or two such batteries, and they usually charge and use battery chargers that use household power. Some users carry a spare battery charged separately from a mobile phone equipped with a battery, and when the battery mounted in the mobile phone is discharged, the discharged battery is replaced with a spare battery.

However, in some cases, the battery does not have a spare battery, and the charging device is also difficult to use, so that the battery mounted on the mobile phone is discharged and the mobile phone is often turned off. In particular, when it is necessary to contact in a hurry, it happens that the user is difficult. Recently, there are many convenience stores in the street, such as charging the battery of the mobile phone for this case, but not only pay for this service, but also to turn off the mobile phone for some time required to charge There is inconvenience.

In addition, in the past, the user of the mobile phone had to carry a spare battery with the mobile phone because the duration of the battery could not be more than half a day, but since the electric capacity of the battery has been recently increased, such a spare battery As the number of users who carry it decreases, the battery mounted on the mobile phone is discharged more frequently, causing a difficult situation.

On the other hand, as a small battery, a power supply using a general battery having a cylindrical shape is commercially available, but a small battery using such a general battery is often disposable and has a problem in that its bulkiness is inconvenient to carry around. Even if a general rechargeable battery is used, there is a problem that a separate charging device is required to charge such a battery.
