Solar Panel Keychain
On February 9, an interesting gadget appeared on the market in Japan - a small solar battery for a mobile phone from the company Strap-Ya, made in the form of a key fob.
Under favorable weather conditions, such a battery can be charged in six hours. But if you do not have time to bask in the sun for so long, you can charge this "makeweight" from the network. As a result, you will receive an additional power source (for half an hour it will work just fine), in case the main battery suddenly dies.
Stuck entertaining. And, perhaps, quite useful: “extra” half an hour can sometimes be vital. The only thing that upsets is the look. Some kind of this battery is too bland, especially for an accessory.
