Description

  The present invention relates to a spare battery carried for use in a mobile phone.

Currently, mobile phones are widespread, but these products cannot be used without a dedicated battery, and communication may become impossible during use due to consumption of the used batteries.
Therefore, a high-performance rechargeable battery that can be used for as long as possible has been developed. However, no matter how high performance the battery can be used for a long time, the battery cannot be used unless the power is consumed and charged. Therefore, in order to use the battery continuously, it is necessary to charge the battery early if it is about to run out, or to carry a dry battery with another spare for replacement.
However, if the mobile phone's dedicated battery is bare and carried around, important parts such as the connection to the phone body may be damaged, or if placed in a humid place there is a risk of leaking electricity, making it suitable for carrying. Did not.

Therefore, the present inventor has previously proposed a portable spare battery device for a mobile phone (see Patent Document 1) which is housed in a special case so as to be suitable for carrying.
However, when the charged battery contained in the device is replaced with a consumed battery, even if the device attempts to charge the consumed battery, it cannot be charged unless it is attached to the mobile phone again. Also, there was a drawback that the mobile phone could not be used during the charging.

Furthermore, recently, a quick charging device dedicated to a mobile phone has been provided, and a mobile phone can be used while charging while the charging terminal of the quick charging device is inserted into the connection terminal. And although the quick charging device is small and light, it is easy to carry, and if there is a power supply, it can be used anywhere and the phone can be used. The proposed portable spare battery device for a mobile phone could not be charged by the quick charging device.
