The 30W Rapid Power Charger's GaN technology helps minimise the charger's size and maximise its performance. The highly adaptable charger is an especially convenient resident plugged into power outlets in cramped spaces. It also occupies next to no space in your laptop bag and backpack pockets. That means you have more room for phones, cards, keys and other essentials. The charger can deliver up to 30W to most USB-C devices, including phones, tablets, and even lightweight notebooks such as the latest MacBook Air and Chromebook devices. GaN Gallium Nitride technology, a next-generation semiconductor material that out-performs silicon, enables very high energy and power output in ultra-compact devices. The charger is also certified to meet and exceed all regulatory standards and features multiple safety functions such as over current protection, over voltage protection, short circuit protection & over temperature protection.
