Universal USB-C charging

The Rocstor Y10A256W1 is a 20W wall charger built for USB-C devices that accept Power Delivery 3.0. It supports iPhone models from 8 through 15 alongside iPad Pro and iPad Air. The adapter also powers any other USB-C device with a draw up to 20W. It is not for laptops or peripherals that need more than 20W.

Compact certified build

The housing measures 1.56" H x 1.79" D x 0.90" W and carries UL and FCC/CE safety marks. A fixed US plug folds into the body so the brick slips into a bag without snagging. The single USB-C port delivers 5V/3A, 9V/2.22A or 12V/1.67A depending on the connected device. No extra cables or interchangeable heads are included.

Automatic power negotiation

The charger detects the attached device and selects the matching voltage and current up to its 20W ceiling. This prevents over-current stress on phones, tablets or earphones that only need 15W or less. The package contains only the adapter unit; a USB-C cable must be supplied separately. Backed by a one-year manufacturer warranty and lifetime phone support.
