X-Man Tornado V4 AI 3×3 UV (Smart Cube + Power Bank) (2025)

X-Man Tornado V4 AI 3×3 UV — Smart Cube

The Tornado V4 with electronics inside. Same shell and the same turning feel as the regular V4, plus a sensor package that reads every move you make.

A high-precision gyroscope and a rotation-recognition algorithm capture each turn, so the app can replay the solve and show you where the time actually went instead of you guessing. It pairs over Bluetooth with the Smart Player Pro app for training, timing and tutorials.

A magnetic foot positioning system with dual positioning handles the alignment, so layers settle faster and stay steadier while you turn.

Battery is where most smart cubes disappoint. This one comes with a 1000 mAh power bank: about an hour to a full charge, roughly 25 hours of solving, and around 25 days on standby. Two ways to charge — on the base or off the power bank — so it keeps going away from a socket.

UV coated exterior, stickerless, with the smaller core design that keeps the cube compact despite the electronics.

Worth knowing: smart cubes are not allowed in WCA competition. This is a training and practice cube.
