Anyone looking for a convenient spare battery can use it anytime, and you don't need to carry a bag that might be of interest in this new solar external backup battery, in the form of a SolarHug bracelet. SolarHug bracelets provide a battery backup, combined with a USB drive that can provide up to 128GB of storage.
What makes the SolarHug bracelet a built-in flexible solar panel allows the device to produce its own energy. In fact, it is a "private power plant" on your wrist, close to the device that you can use and recharge at the same moment.
