Roll cable&extra battery / Extra battery,Cable

Roll cable&extra battery
Roll cable&extra battery

Due to its rolled cable, this extra battery has a convenient shape. Even when the object is far from the person using it, it can be used because the cable is able to stretch. If the smartphone is not charging, the battery is charging itself automatically. Because of that the user can use it while carrying it in a bag. When the cable stretches, a stopper keeps the cable stretched out. After flipping a switch the cable will return to its original state and is usable without getting entangled in a bag. An additional advantage is that the item is also fashionable and due to its small size it can be carried in a bag easily.
