Super Fast Charging: This charger recognizes your devices such as gaming consoles, tablets, laptops, and smartphones, and charges them at maximum speed thanks to the latest charging generation: USB Power Delivery. Power Delivery adds more intelligence to the charger, enabling it to detect the connected device. This allows the charger to deliver exactly the amount of energy needed for charging in the shortest time possible. Ultra-Compact: By using GaN technology (gallium nitride), Energizer manufactures more efficient chargers. This technology reduces heat, increases power capacity, and decreases the overall size of each product. This new line of wall chargers from Energizer is one of the smallest on the market.
