15 Smartphone Gadgets you didn't see Coming.

A portable 1080p display powered by the phone with one cable, useful for desktop mode or watching Netflix on the go.

A sensor kit for playing drums on any surface that he found mind-blowing, though it does not fully match a real kit.

The king of affordable smartphone stabilisers, worth a slight premium for how smooth the footage is.

A sticky pad with a cover to keep the stickiness lasting longer when not in use.

A connected Rubik's Cube with an app that adds guidance and minigames, and a very smooth feel.

A ring that lets you take calls by holding your finger to your ear; it feels first-gen but shows promise.

One of the better mobile gamepads, well built and slides onto the phone so no separate holder is needed.

Probably the most expensive gadget in the series, with mind-blowing results capturing deep space automatically.

A multi-coil wireless charger that doesn't need careful placement and has a separate Apple Watch section.

A tiny speaker that clips onto an empty bottle to boost bass, and sounds detailed on its own too.

A weightless workout tool that turns resistance exercise into phone games, which helps distract from the pain.

A cool concept that turns into a phone stand, but the stickiness is not hugely reassuring.

A simple alarm clock, night light and wireless charger combined that works well if you still use an alarm clock.

A simple all-in-one cable with micro USB, USB-C and Lightning ends plus a USB-A to USB-C converter.

A backpack with a pixel display on the back that is a fun toy, but needs a power bank and offers little real benefit.
