Solar charging devices have been around for so many years. With advance in technology, charging time seems to have shortened. This company, LSTech Co., Ltd, has been making Solar Panel and now it is making mobile size solar charging devices for the mass market.
The above is the largest among its products. It is call SMART Solar-Ro. Unlike most solar charging devices, this device has NO internal battery. It is using only the solar energy to charge devices. You may have seen many solar charging devices (w/o battery) that is so big and it becomes a joke if you are using one.
SMART Solar-Ro, on the other hand, looks like a typical photo frame. According to the promoter, it can charge a device within 6 hours (no mention of capacity or sunlight condition). Nevertheless, to have them say this value out confidently, I am sure that they have done their homework.
It has a built in stand that you can vary the angle.
Here is the back view.

SMART mini is an USB charger, Solar Charger, MicroSD card reader. I cannot believe that such a small device can really help to charge a Smartphone. Nevertheless, if you are in such situation, the solar charging is your best friend.
