Travel Gear: Keyring-sized charger

1. Griffin Travel Power Bank This keyring-sized power pack has only one purpose – despite a name that suggests broader usage – to recharge the Apple Watch. Griffin says you'll get four charges out of its 800mAh battery. This offers peace of mind on your travels where you may be without regular recharging. It's unfortunate that it doesn't charge other devices given its pocketable convenience, but it comes with a lifetime warranty. €70 from griffintechnology.com

2. GoWorx GoKnuckles The GoKnuckles is a new option for using a GoPro action camera. The knuckleduster design, in a selection of colours, makes it a secure alternative for adventure filming, with a waterproof, rubbery finish on the heavy-duty plastic grip. It's compatible with the Hero range, you can point the camera whatever way you want, and the grip is neat enough to let you hold something else with the same hand. $20 from goworx.com

3. Polaroid SLR670m Land Camera A clever reinvention of the iconic Polaroid instant camera. MiNT takes the existing body and reboots it with a new electronic eye, a new motherboard and a new clip-on piece of tech, the Time Machine. There are 16 manual settings, with long exposures and a high shutter speed. It all looks seamlessly authentic but such stylish instant gratification comes at a price. €533 from mint-camera.com
