Smartphone detachable auxiliary battery device having a holder device {Smartphone detachable auxiliary battery device with holder device}

The present invention relates to a detachable auxiliary battery device for a smartphone having a holder device.

Recently, as the spread of portable terminals such as smart phones and tablet PCs that provide high-quality video and high-quality music has increased, TV and movies are available through portable terminals. The time to watch YouTube or listen to music is increasing. At this time, in order to watch the video, the mobile terminal must be held by hand, and pain is induced in the wrist and arm as the mobile terminal is held in the hand for a long time. In addition, as the picture quality of portable terminals increases and the number of programs used increases, battery power consumption is high, so that charging power of the battery cannot be maintained for a long time. In relation to this, various types of cradle for holding a mobile terminal at an appropriate angle for viewing have been introduced, and prior art related to such a mobile terminal cradle has been disclosed under the name of a portable terminal cradle in Patent Registration No. 10-1140806. there is. In addition, Korea Patent Registration No. 10-1502738 proposed a holder for a portable terminal. However, the prior art has only a carrying and stationing function of the portable terminal, and thus has limitations in terms of managing battery charging power of the portable terminal. To solve this problem, Korean Patent Publication No. 10-2021-0153007 discloses a non-slip grip talk, and Korean Patent Registration Publication No. 10-2341386 discloses an auxiliary battery device for mobile devices. No. 10-2019-0073893 discloses an auxiliary battery that can be coupled to a mobile terminal. However, in order to use GripTalk, the entire device must be attached to a smartphone and used, so there are many inconveniences in using GripTalk in a situation where charging is not required. In addition, even if the Griptalk is separated from the wireless charging device, there is a problem in that only the Griptalk cannot be independently attached to the smartphone, so there is a limit in that the wireless charging device and the Griptalk must be used together.
