Battery symbol on USB ports signifies faster, bi-directional charging

By PulseAugur Editorial · [3 sources] ·

A battery symbol next to a USB port typically indicates USB Power Delivery (USB PD), a protocol that allows for faster and bi-directional charging. This technology, which predates USB-C but was updated in 2021 to support up to 240W, enables intelligent digital handshakes for optimal power transfer and can even charge devices when the host is asleep. While the USB Implementers Forum has an official negative-space battery symbol, companies like Apple, Microsoft, and HP may use variations such as a different battery logo, a lightning bolt, or simply 'PD' to denote USB PD compatibility, with some ports offering this functionality without a specific indicator.
