19 Smartphone Gadgets you never knew Existed.

A cable, keyring, torch, stand and microSD adapter in one, but the 9-volt battery feature strikes him as odd.

A very impressive pint-sized projector with autofocus and auto-correction, though not cheap.

A simple cover that hides cables over your charging brick and lets the phone stand upright.

A pricey but one-of-a-kind digital canvas that makes artwork look like real paintings.

A fun, wacky charger with LED lights and dual USB ports, but not for fast-charging phones.

The best portable phone monitor he has shown, slim with a great stand and touchscreen, but dim with no battery.

A surprisingly capable smart wallet with GPS, alarm, thief camera and battery, held back by thickness, price and a poor Android app.

His favourite Bluetooth keyboard for smartphones thanks to its folding design, though it can fold up on uneven surfaces.

A selfie stick with near pro-level features including tripod mount, stand and detachable remote.

A cool concept with questionable execution, as it is no more accurate than a finger.

A smartwatch he has used for three and a half weeks that impresses with its dual display and 30-day LCD battery mode, despite not being a smartwatch fan.

Bought to prove that different is not always good, a badly designed speaker that makes you use a remote instead of your phone.

A handy desk power tower for gadget hoarders with six mains sockets, USB ports and wireless charging, if a little cheap-feeling.

The best screen wipes he has tried, cleaning fingerprints without scratching or streaking.

A tiny, well-finished phone dock with USB-C, HDMI, USB-A and a headphone jack.

A USB-C dock that also works as a 5000mAh battery and 5W wireless charger.

A nice two-device wireless charger with extra USB-A and USB-C ports, good for overnight charging.

The best system for attaching lenses to a phone he has used, but the lenses themselves are only okay.
