19 Smartphone Gadgets that Blew me Away.

A small wheeled dolly that gives smooth, circling shots when a phone is mounted on it.

A backpack with a touch-sensitive panel for controlling the phone, handy but nothing you couldn't already do.

Best mobile game controller he has used, with polished software, though iOS only.

A fun, nicely finished cable whose magnets keep it tidy once wound up.

A very secure wrist strap that stops you dropping your phone.

Generic-looking but well-thought-out adjustable stand that also clamps to a desk.

Cheap wireless charging dock with a louder speaker, but built with the iPhone in mind and awkward for the Note 20 Ultra.

Wireless touchscreen phone monitor he could not fully test as his unit was pre-production.

The fastest, snappiest wireless screen projection he has used, despite the faff of a transmitter and receiver.

Compact, sturdy 26,800mAh power bank with four USB-C ports and 138W output.

A strange folding triple wireless charger that becomes a cube with clock, alarm, speaker and light.

A plain no-frills power bank that becomes more interesting docked into the HyperCube.

A 200W charger that powers four devices and supports many protocols, a major decluttering tool.

An extreme power bank that can charge nine devices at once and recharges in two and a half hours.

An affordable, good gamepad with adjustable shoulder buttons and a fan that cools the phone.

Odd but surprisingly functional zinc alloy triggers that are well considered.

Legitimate but odd finger sleeves; he mainly bought them for the hilarious product page translation.

Still amazing value at around $30, but clunkier and not as good value as the first Basics.

One of the best value watches full stop, with strong features and about a week of battery for just over $30.
