Power, charging & USB-C
A USB-C connector identifies a connector system. Supported charging power and data capabilities depend on the devices and cable.
Power Delivery
USB Power Delivery lets compatible equipment negotiate power. Check the product’s specified input and cable requirements rather than assuming every USB-C peripheral supports the same charging modes.
Reading battery figures
Capacity in mAh describes charge. Energy in Wh also accounts for nominal voltage. Runtime depends on power consumption, lighting, radio mode and usage, so compare battery-life tests under matching conditions.
