This article covers GameSir G8 Galileo Type-C 有線ゲームコントローラー Android & iPhone 15-Serie用 (USB-C)スマホ ゲームパッド.

Overview

The GameSir G8 Galileo is a wired mobile game controller that transforms your smartphone into a portable console. Its key innovation is a movable USB-C connector that plugs directly into iPhone 15 series or Android devices, eliminating Bluetooth pairing and input lag. The controller adopts full-size analog sticks and buttons comparable to console controllers, providing a comfortable grip for extended gaming sessions. This model targets mobile gamers who demand low-latency, precise controls for action games, shooters, and cloud gaming services. With pass-through charging and customizable faceplates, it balances performance with personalization.

Connectivity & Compatibility

The G8 Galileo connects exclusively via USB-C, with a sliding connector that adjusts to different phone positions. It supports iPhone 15 series (15/15 Plus/15 Pro/15 Pro Max) and Android smartphones with a USB-C port. Note that thick phone cases may prevent a secure fit, so removing the case before play is recommended. A pass-through USB-C port on the bottom allows simultaneous charging of the phone while gaming, so battery anxiety is not an issue during long sessions.
