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.
