Inductive charging (also known as wireless charging or cordless charging) is a type of wireless power transfer. It uses electromagnetic induction to provide electricity to portable devices. Inductive charging is also used in vehicles, power tools, electric toothbrushes, and medical devices.
USB-C and Qi wireless charging supported carry case with inbuilt lithium iodine battery that can charge the earbuds two times. Ear tips: Included ear tip sizes: Small, medium, and large. The intermediate sizes extra-small, medium-small, and medium-large, may be bought separately.

Although a single lithium cell will typically provide ideal power to replace to 3 NiMH cells, the form factor means that the device still needs modification.
Of note, the Surface Dock for Surface 3 and Surface Pro 3 used a new 40-pin interconnect on the right arm of the dock to join the device to the docking station for charging and port replication use. The port featured in several generations of Surface Devices afterward. Surface Dock (Brick)
