Tencent Digital (Gao Xiang) As most of the smart phone's battery is not power, a variety of mobile power naturally becomes a hot product, attracting people to buy. Some are large enough to punch laptops, some are as thin as cards, and some use solar energy.
There is a schoolbag.
This iCoolPack, which does not look too different from an ordinary computer bag, actually has two great stunts. First of all, built-in 15600mAh battery, and 3 USB fast charge interface + 1 USB-C interface, so that it can charge mobile phones, tablets and even laptops.
Secondly, iCoolPack also has three fans built into the back of the backpack. You can use the mobile app to adjust the wind speed. When you go out in the summer, it is a "carry air conditioner." These fans support IP68 waterproof, so don't worry about the short circuit caused by sweat on the back.
In addition, the iCoolPack's USB interface features an easy-to-access design that supports up to 5.2V/2.4A output and can be charged up to 3 devices simultaneously. With a mobile application, each USB interface can also be managed.
You may worry that a school bag carrying such a large battery capacity will carry a "bomb"? iCoolPack's developers said that it uses a world-class TI control chip and high-quality Panasonic lithium battery to ensure that the entire battery system operates safely and stably.
So, how long can iCoolPack use? If it is iPhone 7, it can achieve 6 full charge, 12-inch MacBook is 1 time. As for the fan, up to 5 hours of operation can be achieved.
iCoolPack backpack also uses a hydrophobic material, to deal with light rain, splashing what is not a problem, the schoolbag itself also has a lot of space, enough to meet you for a short trip.
iCoolPack backpacks are currently being crowdfunded, the price is not cheap, Super Early Bird price is 1299 Hong Kong dollars (about 1132 yuan), if the crowdfunding will be successful delivery in June 2017.
