Phone accessories

His favourite smartphone printing accessory, working with no Wi-Fi, power or battery and giving vintage-looking prints.

An odd-looking elastic strap that works like a backpack for small items and is comfortable to hold.

A stretchy stick-on wallet with a fold-over flap that he would trust with cards and cash.

An extremely resistant case that floats, resists drops and prevents overheating, though the battery claim is the company's.

A glass cleaner that works surprisingly well on phones, removing fingerprints and leaving a silky finish.

A clever two-way clamp for using a phone alongside a laptop, as long as the laptop hinge is good.

A viable, unusual alternative to a cleaning cloth that leaves screens spotless.

A LEGO-style case that is fun and colourful but neither comfortable nor very protective.

Looks like folded plastic but solves the problem of phones dangling from high wall sockets.

A trackable wallet with a remote buzzer that he was happy to find and thinks looks nice.

Fiddly to set up and does not fill the screen, but the 40x zoom effect is impressive and unmatched by other phone gadgets.

A glorified plastic bag, but it worked brilliantly for snorkelling footage in Greece and beats a cheap disposable waterproof camera.

His favourite of the spider stands he has covered, stable and able to hold phones, tablets and e-readers.

A simple four USB-A plus one USB-C charger that he calls one of the best current ways to charge all your devices at once.

A pocket screen cleaner that wipes away fingerprints and smudges quickly, and got surprising reactions from people he showed it to.

A big, cheap air blower, more useful for cleaning accessories and the room than the phone itself.

The wireless charger he would pick if he used one, with USB-C input, a second USB port and fabric finish, but not cheap.

A car-key-style remote that controls playback, volume and the camera shutter.

A handmade wrap that stops earphones tangling and can clip to a keychain.

A basic phone dock that amplifies the speaker and has a pen slot, useful but not remarkable.

His favourite power bank thanks to its solid capacity and built-in AC adapter.

A neat flexible clamp mount for using your phone in bed or at a distance, though a bit wobbly when touched.

Combines a phone stand and a GorillaPod with eight adjustable legs, and has the best name on the list.

A magnetic cable kit with micro USB, USB-C and Lightning connectors, handy for mixed Apple and Android households.
