Travel Gear: Using your body as a recharger

Plus the fold away wheely and a tough camera-torch

Ampy Move Checking the expected battery life of any new mobile gadgetry has become a key consideration. We all know that feeling of peering anxiously at the last sliver of charge just when it's needed most. Ampy has introduced an alternative to solar or wind-up for off-grid power by tapping one's own kinetic energy to recharge. Inside Ampy's Move a pair of inductors convert your body's movements to energy. There are optional accessories to strap it on a limb for cycling or running for maximum effect.

An hour’s exercise promises an hour of smartphone charge or 24 hours of smart watch use. There’s an app too, of course, with fitness tracking and so on. The more vigorous the movement the better: so plenty of imaginative ways to harness your kinetic potential. $99 from getampy.com

Heys Stealth Luggage Luggage is being reinvented in lots of ways, from digital self-weighing cases to integrated tracking online. Here's an analogue fix from Heys, with a set of aluminium wheels that can fold away at the press of a button. So saving a bit of space in the overhead and wear and tear from luggage handlers. The cases are robust polycarbonate and are in a range of sizes. From $250, heys.ca

Torchscope As portmanteau names go Torchscope doesn't quite do what it says on the can as it's actually a flashlight with a built-in camera rather than a "scope" of any sort. It combines a powerful LED 1,000 lumen torch with an HD video camera which can time-stamp footage. The casing is military-grade aluminium, and the Torchscope is 1m drop-proof and waterproof to 10m. There's an integrated mic for audio and an SD card slot to store your productions. $299 from borescopestore.com TOM KELLY @tomtomkelly
