Rid yourself of outdated chargers along with their bulky sizes and slow charging speeds.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 20W of Power Delivery (PD), this charger provides the fastest and most efficient charging for Apple® iPhone® and iPad®, Samsung® Galaxy S®, other Android™ phones and tablets, or any other device with a USB-C® power input requiring up to 20W power delivery.
