The G502 Lightspeed needed to borrow some of this space for the optional PowerCore module that is required to enable wireless charging with PowerPlay. By removing a cover from the bottom of the mouse, users can find slots in which to add up to 16g of additional weights. One of the major features of the G502-series is its adjustable weight system. That’s because while the G502 Lightspeed may look and feel the same on the top, discerning owners of wired G502 models will notice some differences on the bottom. But, thanks to this impressive engineering effort, the G502 Lightspeed looks and, more importantly, feels just like its wired counterparts, at least in all the areas that matter.

As Logitech explained, “It’s like asking a car designer to keep a car the same on the outside, but add a bigger motor, a hot tub and full bar.” Indeed, Logitech tells us that the only physical component of the mouse that wasn’t changed in some way are the PTFE feet on the bottom. The company’s engineers therefore spent months meticulously redesigning and reengineering the G502 Lightspeed, not to end up with a product that was different, but to end up with something that was as close to the original as possible. But Logitech had a winner on its hands with the G502, and neither they nor the legion of G502 fans wanted to see any drastic changes. Space must be made for the battery, the inclusion of which also affects weight and handling, and the energy efficiency of the the sensor and RGB lights becomes a critical factor. That’s because making a wireless version of a mouse requires some important modifications.

But just because the exterior of the mouse looks virtually identical to its wired predecessors doesn’t mean things haven’t changed under the hood. In fact, with the micro USB charging cable attached, fans of the G502 would be hard-pressed to easily identify any differences. And this new wireless version continues to build on Logitech’s subtle refinement of this aggressively designed, yet surprisingly comfortable mouse. The wired version of the G502 has seen several revisions over the years - from the Proteus Core to the Proteus Spectrum to the HERO edition released late last year - but they all shared a very similar physical design.
