20 Crazy Smartphone Gadgets for 2020.

The best mobile game controller he has used, with almost no input lag, though pricey and not premium-feeling.

A clever speaker that splits into a stereo pair and houses earbuds, with great battery life, though the case is bulky.

A versatile and affordable two-axis gimbal that doubles as a tripod and extendable selfie stick.

A cool curved-screen watch that is more fashion accessory than a smartwatch doing much more than cheaper rivals.

Mentioned as a more affordable smartwatch alternative to the Amazfit X.

A compact 120W gallium nitride charger that can run three devices at full speed, including two small laptops.

A simple power bank with a kickstand that wirelessly charges a phone while it sits on it.

A phone pouch that charges wirelessly, part of a range designed for a belt, which he finds a bit cowboy-like.

A 10,000mAh power bank with an animated LED strip that doubles as a battery indicator.

A power bank that sticks to the phone with 20 suction cups, like a bulky case.

A stylus with built-in UV lights to sterilise your device; this version only works with iPad.

Combines a UV cleaning box with a wireless charging pad.

A Bluetooth speakerphone with six microphones, more useful than he first expected.

A brighter, louder bigger brother to the Nebula Capsule-style mini projector, with built-in battery and Android, though less portable.

A pocket speaker with surprisingly good sound that mounts magnetically and expands for deeper bass.

A long-range Bluetooth transmitter and receiver that cuts down on cables.

An aluminium adjustable stand for the back of a phone that clicks into place; he is impressed by how much it packs in.

A travel adapter with four full-size USB ports that he plans to use regularly.

A well-built but very expensive niche polariser that reduces reflections when filming on a phone.

One of his two favourites in the list: an empty laptop shell powered by your phone that is cheaper and lasts ages on battery.

A wearable 'monitor for your face' that works with phones and consoles, but probably not as good as its 200-inch claim suggests.
