The second-generation Legion Go keeps twin USB4 40 Gbps USB-C ports but upgrades to DisplayPort 2.1 for higher-refresh external displays, and adds a 3.5mm headset jack absent from the original. Both ports support 100W USB PD and external display output — one handles a dock or eGPU while the other supplies power. Like its predecessor, there is no official Thunderbolt 4 certification, but USB4 eGPU enclosures are confirmed compatible. The 74Wh battery makes the 100W PD charge rate genuinely useful.

Two upward-facing Thunderbolt 4 USB-C ports solve the original Claw's single-port limitation — one drives an eGPU while the other handles power and peripherals, or both supply simultaneous 4K display output. Maximum charging is 65W per port (45W during active gaming load). Intel's Lunar Lake platform is paired with Wi-Fi 7 and Bluetooth 5.4. No USB-A ports are on the handheld itself — a USB-C dock is the intended peripheral hub. This is the most TB4-capable gaming handheld in its class.

The handheld PC that made the format mainstream runs a custom AMD APU inside a surprisingly capable connectivity shell. Its single USB-C port operates at USB 3.2 Gen 2 with DisplayPort 1.4 Alt Mode — one dock connects to a TV and handles 45W charging simultaneously. There is no Thunderbolt and no proprietary dock protocol, so any standard USB-C hub or dock works without caveats. The microSD slot accepts cards up to 2TB for storage expansion.
