The ALTHEA12W USB charger offers efficient and fast charging, featuring 2 USB Type-C ports with Power Delivery (PD) 3.0 technology. Automatically detects and charges devices such as MacBook, Nintendo Switch, iPad, iPhone, Samsung etc., at up to 65W speed. Gallium Nitride (GaN) chargers provide a smaller, streamlined alternative to traditional silicon, resulting in more efficient chargers and power supplies. They require fewer components in order to operate, and are able to conduct much higher voltages over the typical lifespan of a charger or power device. They also generate less heat than traditional chargers, which results in greater efficiency and more power directed to the device rather than being lost. The charger is protected against overload, short circuiting and overheating, and with a compact and light-weight design, it is a great travel device and daily companion.
