Some will miss optical zoom, though the flip-side of its 'no moving parts' design is a totally waterproof, underwater mode that makes this portable a great candidate for snorkelling or diving.

6. Geneva Sound System Model XS

10 top gadgets for your summer holiday
The Geneva Model XS offers a mighty sound quality for its size

Travel speakers are routinely sold with tall stories of turning tables into speakers and hotel rooms into discos. Ignore all that and go straight for the best-sounding by size: this Swiss-made speaker system that doubles as an alarm clock.

Connecting to a smartphone or laptop via Bluetooth, the Model XS also throws in a DAB+ radio. And it all snaps shut in a travel-friendly clamshell case.

It's also really useful for business trips, able to act as an impressive hands-free speaker for conference calls.

This powerful headtorch from Petzl will light your way

You'll see Maglite torches in the gift sets on the plane, but it's an LED head torch from Petzl that you really need.

Powered by three AAA batteries and comfy to wear, the biggest beam is powerful enough for upcountry hiking in the pre-dawn darkness while a less powerful setting is just right for finding your hotel room late at night.

It also features flashing modes, and red light setting for stargazers trying to preserve their night-vision while dodging guy ropes on campsites.

8. Thule Perspektiv SLR Daypack

10 top gadgets for your summer holiday
Thule's waterproof backpack will keep your possessions safe and dry

Is this the finest outdoorsy camera bag available? If you're taking your DSLR on holiday, this backpack from Thule with easy-vis bright blue compartments galore can take a camera and multiple lenses. It's ideal as both cabin baggage and for day trips, but that's not what makes it special.

Though its undercarriage is pleasingly tough and strong, it rather unexpectedly hides a useful rain cover, which covers the entire (and already water-resistant - even the zips and seams) daypack in the event of a downpour.

There's even a totally waterproof section for storing SD cards, a stash pocket and a clever tripod clip on the front, and - best of all - it's comfy to wear on a hike around town or up a mountain.

9. Goal Zero Yeti 1250

This Goal generator can supply enough power to charge a laptop 20 times over

For long-term campers and caravanners headed off to remote parts with gadgetry in tow, a generator is a noisy necessity.

But there is a less intrusive option: this silent (if heavy at 54kg) option from Goal Zero, which stores a mighty 1500W of power within. That's enough to recharge a laptop twenty times over.

About 15 hours refuels it from a wall outlet, or even via a USB cable, but if you're off on a long trip to (say) the Australian Outback you'd be a fool not to add the optional solar panel that recharges the Yeti inside 20 hours.

10. SATcase for Android

10 top gadgets for your summer holiday
For the real adventurers out there, this case transforms any Android smartphone into a satelite phone

Probably overkill for two weeks in the Med (unless you own a yacht), but adventurous types take note. Aimed at hikers, sailors and aviators, the SATcase (due to be launched later this year) transforms any Android smartphone into a satellite phone - thereby bypassing the globe's patchy 3G network.

SATcase is the first satellite phone kit that swaps a bulky receiver unit for a smartphone app, and comes in a rugged case. It also contains a 406 beacon that search and rescue teams can find using the COSPAS-SARSAT system.
