Short-form mobile videos are everywhere, but until now they’ve relied only on smartphones. Cue the Akaso Keychain, a seriously tiny clip-on camera that’s seemingly designed for TikTok, but has some core extra features that might just widen its appeal. 

Described as a ‘mini vlog’ camera by its creators – which recently launched the impressive Akaso Brave 7 LE action camera – the splash-proof Keychain is claimed to be the lightest 4K camera around. It’s hard to argue with that; it measures 63x33x18 mm and weighs just 36g, with a microSD card slot and a USB-C slot hidden away behind a flap on its undercarriage.
