Brunton – Revolt 9000 mAh Waterproof Portable Charger

You plug it in, fill it with the magic of electrikkery and take it off on your holibobs or, in my case, hospital. With only Sky News, crappy games and my evil, mickey-taking Facebook friends for company on my iPhone 6 (and the slightly less evil Mrs Muz from 2.30pm – 4.30pm and again from 6pm – 7pm), I managed to drain my phone a couple of times over. And the Brunton Revolt was a sanity-saver.

Xtorm – Lava Charger

The Lava Charger comes in the box with a 75% charge, so you can buy it and charge your phone immediately if you’re stuck. And Xtorm say that it takes just 8-hours of sunshine to charge the Lava back up to full – we have that on test at the moment. In practice, we got what showed as a 3-quarter charge out of a typically British summer’s day. We’ll take it touring next time we go abroad somewhere sunny and see if we can up that to a full charge.

Xtorm – Yu Charger

In practice, the Yu charges pretty well for its size. It’s certainly more efficient than many solar chargers from a couple of years ago – technology moves on – and if you had a less intense device or demand, then it would work well as a top-up charger. It will certainly allow you a couple more facebook updates and instagram sessions than you would normally be able to get after a day’s normal British hiking. It isn’t, however, a “my only source of power” option for longer trips or less clement weather. That would be more suited to its big brother, the Lava Charger, which we’ll be reviewing shortly.

Powertraveller – Powergorilla

I’ve managed to flatten my car battery using an inverter, and have had a laptop jerry-rigged to run off a jump-starter pack before now, which filled me with dread. The Powergorilla just gives a more professional and dependable solution. And so long as you are organised and keep the correct adaptor tips in the right place, it’s a really neat solution for those who need adaptable power.

Goal Zero – Guide 10+ Adventure Kit Solar Charger

We’ve put a few solar chargers through their paces at GearWeAre, but we’ve never been completely convinced about their practicality versus their cost. Until now. The Goal Zero Guide 10+ Adventure Kit is actually a conglomeration of their Nomad 7 Solar Panel and a Guide 10+ battery pack, and we’ve been testing the whole thing out over the last months.

Freeloader Classic solar charger

So concerned were Solar Tech that they arranged to send someone to see me on a 140-mile round trip, but I had a eureka moment beforehand. Because my phone is jailbroken I have a percentage value of the remaining battery power on the screen. I realised that the more power I had in the phone when I plugged it in to charge, the better chance there was of the Freeloader behaving itself and the phone fully charging.
