Rid yourself of outdated chargers with their bulk size and slow charging speeds. Upgrade to an ultra compact, efficient, safe, and powerful USB Type C charger with Gallium Nitride (GaN) technology from Monoprice! Gallium Nitride is a superior material for semiconductors than traditional silicon, with higher voltage levels, need for fewer supporting components, and more efficient current transfer. This means there is less power loss to heat, a smaller form factor, and significantly faster charging than silicon based chargers. Featuring 20 watts of USB C Power Delivery (PD) and up to 32 watts of total power, this charger provides the fastest and most efficient charging for Apple iPhone and iPad, Samsung Galaxy S and other Android phones and tablets, and any other device with a USB Type C power connection.
