More on LIGHTSPEED Wireless

No Wires, No Limits

LIGHTSPEED™ wireless technology is as fast or faster than many wired gaming mice. And that was the required benchmark for LIGHTSPEED™ viability. Total freedom of wireless with absolutely no compromises.

140 Hours. One Charge.

HERO 16K is super-efficient, delivering incredible battery life that lasts up to 140 hours of gameplay with LIGHTSYNC RGB lighting in full effect - and up to 180 hours with no lighting. That's almost 6X the battery life of the previous-generation G903.

1ms Super Fast Wireless

Logitech G engineers created an end-to-end technology optimization from sensor to firmware, circuitry to antenna. We tested and refined each component, focusing on the slowest link until nothing was slow.

POWERPLAY Wireless Charging

Get ready for endless gameplay. The POWERPLAY wireless charging system keeps G903 and other compatible G mice charged while at rest and at play.* Just attach the included POWERCORE replacing the optional 10 g weight and cover. Never worry about battery life again.

* POWERPLAY Wireless Charging System sold separately.
