PNY Outdoor Charger 7800 mAh Portable Power Bank

PNY Outdoor Charger 7800

£24.99, Amazon

Scaling a summit or strolling through the countryside can be the perfect antidote to a life spent plugged into technology. And yet, sometimes reaching those summits and seeing a lovely landscape isn't enough; a picture is needed, but it seems a waste of precious phone battery. Here is where a portable charger comes in handy. This PNY model is coated in rubber, making it a hardy companion on less than delicate yomps, and pumps phones, cameras and any other tech with juice on the go via the USB ports.

Lifestorms Intensity 105 LED Head Torch

£19.99, Lifesystems

Lighting is key on hikes through dark valleys and as night sets in, but holding a torch can prove problematic, particularly on uneven pathways. Fasten the elasticated Lifesystems Intensity torch to your head and roam free without the worry of stumbling into the unknown. There are six light modes and a rechargeable battery - each pack comes with a micro USB to charge between walks - offers up to 25 hours' light.

Fitbit Flex 2

Fitbit Flex 2

£69.99, John Lewis

Fitness trackers are 10 a penny, but this reliable model from Fitbit covers the basics without being too bulky or bogged down in technical detail. Attach to your wrist and the waterproof band will count your steps and keep a tally of any fitness goals as you stride. Link it to a smartphone, double tap the band and wait as lights appear. Each solid light represents a quarter of the day's fitness targets completed. It'll also give you a nudge if you've been inactive for too long, but you can turn this feature off!

Apeman Sports Action camera

£33.99, Amazon

For those who prefer a gentle Alfred Wainwright-esque ramble, this Apeman action camera probably won't do. But for pluckier climbers and hikers, this portable little camera can be attached to chest straps - or even dog harnesses - to give you a different perspective on meanderings.
