Lenovo Legion R7 RT75 gaming keyboard brings Hall effect switches, TFT display, and massive 8,000mAh battery

Lenovo has expanded its Legion gaming peripheral lineup with the new R7 RT75, a magnetic switch keyboard that packs some impressive specs for the price.

Specs at a glance:

  • Layout: 75% compact
  • Switches: Hall effect / magnetic with adjustable actuation
  • Polling rate: 8,000Hz
  • Battery: 8,000mAh (double what most gaming keyboards offer)
  • Build: All-aluminum body
  • Display: TFT screen for system stats and custom graphics
  • Connectivity: Wireless + wired
  • RGB: Per-key RGB lighting
  • Also launched alongside it: Legion Y7MG mouse with PixArt PAW3950 sensor and 8K polling

Why the battery matters

Most wireless gaming keyboards run between 2,000-4,000mAh. The 8,000mAh battery in the R7 RT75 is double what you typically see. With RGB off this board could easily last weeks between charges. Even with RGB on it should outlast most competitors by a significant margin.

Hall effect switches

Magnetic switches mean adjustable actuation points, rapid trigger support, and better durability since there’s no physical contact wearing down. This puts it in the same category as the Wooting 80HE, Razer Huntsman V3 Pro, and Keychron’s HE boards. The 8K polling rate ensures the input latency is as low as it gets.

TFT display

The screen on the board can show system stats, connection status, or custom graphics. It’s becoming a common feature on higher end gaming keyboards and Lenovo’s implementation looks clean based on the early photos.

Price and availability

¥1,299 CNY in China, which works out to around $180 USD. Waiting on international pricing but that’s a strong price point for what you’re getting.

What do you think? Is Lenovo finally a serious contender in the gaming keyboard space or is this just another big brand playing catch up? And would you take an 8,000mAh battery over hot swap switches?
