Apparently a simple key ring with an appealing design, but in reality it is a very practical 1650 mA / h power bank inserted inside an ABS shell with a rubber finish. By releasing the two side bands, a USB cable will be available for charging the power bank, while on the opposite side, depending on the model.
Wireless Stereo Headset with retractable cord. Allows you to make calls using the in-ear headset and rewind it when not in use. By pressing the appropriate button the cable rewinds, leaving maximum freedom and avoiding clutter. It connects wirelessly with two devices simultaneously and is activated automatically when one of the two receives a call.
