Universal portable battery

A funny thing - a portable charger in the form of a bracelet. Apparently, the designers paid attention to the suddenly empty space on our wrist, which was traditionally occupied by wrist watches in the “home” period. Convenient and stylish, but the most interesting is eight different connectors, which, according to the authors, will allow you to charge any gadget.
The bracelet uses a lithium-ion battery, which takes about 5 hours to charge. As a direct power supply, it provides up to three hours of mobile phone talk time and up to 8 hours of player operation.
