Brunton Pulse 1500 charger, £30

The Brunton Pulse charger is so diminutive you probably won't even notice you need it until the crucial moment when your phone runs out of battery half way up a mountain. The good thing is that it works equally well for a long night on the tiles. brunton.com

GoPro HERO3+, around £240

If adventure to you means abseiling, skydiving or basically anything more hardcore than walking, get yourself the latest GoPro. The Hero3+ is the lightest model yet with a better lens and video mode to capture you doing something ridiculous. gopro.com

Heimplanet The Cave tent, £450

It's a common problem: hike for miles, and can't find a hotel. Obviously, the solution is an inflatable tent. The Heimplanet Cave tent might look like something out of the Crystal Maze but it's light and stable, making it the ideal travel companion. heimplanet.com
