The Samsung Micro USB-C Charger Adapter Adaptive Fast Charge with cable allows you to quickly charge your Samsung smartphone. All Samsung smartphones charge about 1.5 times faster with Adaptive Fast Charge than with a regular charger. Samsung Adaptive Fast Charge is Samsung's version of the fast charge protocol Quick Charge. This means that you can use this charger on all Android smartphones with Quick Charge. The only devices this charger doesn't charge optimally are those with Power Delivery, such as the iPhone and Samsung Galaxy Note 10 Plus. You can still charge them, but not at the highest speed. Note: this charger includes a USB-C cable (round connector). Some older smartphones still have a micro USB connection (square connector).
