Supports a maximum 45W Super Fast Charging 2.0 for Samsung, so you can fully charge your Galaxy S23 Ultra in under an hour. Note: Super Fast Charging 2.0 requires a 5A charging cable (not included). Features a total of 10 safety features including short-circuit protection, high-voltage protection, and temperature control to safeguard you and your connected devices. At 30% smaller than an original 45W USB-C charger and with a foldable design, Anker 313 Charger (Ace, 45W) takes up less space while giving you just as much power. With higher energy efficiency and upgraded heat dissipation, Gallium Nitride (GaN) makes our chargers smaller and safer without sacrificing a drop of power.
