Smartphone signal boosters and battery extenders are nothing new. In fact, we have covered a bunch of them in the past. WiFiBoostGo happens to be an interesting device that aims to combines those two features in package. It increases your signal range up to 600%. It also serves as a portable power bank for your smartphone.
The SLIM version has a 3000 mAh battery that is fully charged fast. It supports up to 128 GB flash storage. The device is compatible with iOS and Android devices. The WiFiBoostGo BOLD version has an even bigger battery. You can find it on Indiegogo.
