The JUP40 provides multiple ports giving you the ability to charge up to 4 devices simultaneously. One port is equipped with Qualcomm Quick Charge 3.0 support, allowing you to charge your QC 3.0 compatible smartphone 4x faster than a standard charger. The other three ports are equipped with Intelligent Identification technology, which means that it adjusts the power to each port based on demand. Each USB port is capable of delivering up to 2.4A of power. This is enough to charge a tablet, such as the iPad Air, quickly, or a less demanding device, such as a phone. Of course, each port will only deliver the required power. The charger also comes with surge protection, protection from overcharging, over current and overheating, keeping your devices safe.
