Everything I've tested.

One of his favourite power banks, a 6000mAh cassette-styled unit with a slick cable.

His new favourite power bank for its 45W output, enough for a Huawei laptop-class phone and MacBook.

Clip lens covering macro, wide, ultra wide and fisheye shots.

His go-to headphones when leaving the house, with good battery, comfort and sound.

Lint-roller-style screen cleaner that is an option but not his favourite.

Full-size wireless keyboard that is very portable.

The splitter he recommends, as it clips to a key chain and avoids dangling cables.

Nifty two-in-one fidget spinner and ring holder for the back of a phone.

Easily one of his favourites, a small printer needing no Wi-Fi, cable or batteries.

Tiny USB bulb to use with a power bank as a high-efficiency lamp.

Pretty good way to get dirt out of hard-to-reach areas.

A very good way to add three USB ports to an OTG-capable phone.

Smart stickers let you track what is in storage boxes by photo and scan.

Stealthy under-desk gadget that hangs headphones and charges up to three devices.

Connects to laptop and phone so both displays are visible from the same angle.

One of the most portable and coolest ways to type on the go, though it needs a flat surface.

A dock only for those very serious about their phone, adding USB 3.0, HDMI and Ethernet.

Cable with built-in light that visualises the flow of electricity while charging.

A slick elastic macro lens that lets the phone camera go much closer.

Waterproof suction-cup shower speaker that is much louder than a phone.

Most portable and flat-lying gamepad he has come across, though the buttons are not great.

Memory drive that plugs into both computer and phone.

An absolute lifesaver magnetic cable that charges like a MagSafe adapter.

Plug-in mic that steps up audio for vlogging or calls.
