Carry-With Batteries & Solar Panels To Keep Your Devices Topped Up This Festival Season

Devices Run Out Of Power

You simply can’t afford for your phone, camera or gimbal to run out of power. The portable battery and solar panel gives you the assurance that you can survive a whole long weekend of hard partying and outdoor chilling, parched dry or drenched soaked without the fear and panic of running out of juice.

Powering Luxury Devices

Do you take your fridge? A portable cooling fan? LED lights for inside the tent? Shaver? Hairdryers? Projector? Cooker? Air fryer? (Seriously). You probably won’t stuff these in your backpack but they’d fit in your van or car and – can run from your portable battery and solar panel. Having portable, clean and free energy really can open up a whole new festival experience with the tech convenience you love on top of the memorable, magical times you enjoy on site.

Create Better Content

With extra power in your van or tent, you can spend a little extra time adjusting, editing and uploading your content, with your add on storage drives, gimbals and extra lighting all completely powerable now that you have backup power. Spend more time reviewing others’ content, uploading and downloading live from each gig as opposed to saving it all up for the big edit back home way after the event has completed.

Be Even More Loved

With your own battery and enough sun to keep you recharged, you’ll be able to share like never before: offer to charge your friends’ phones, set up wifi hotspots without the worry of the superdrain on your own phone’s battery. Your friends will love you for it, and you may well make new ones as a result.

Play Your Part

The climate needs us all to do our part and having your own battery powered by the sun is just one very small step you can take on your own journey of making a difference. The energy created from the sun is the purest possible – it’s free, it’s clean, it’s sustainable. Take a portable battery with a small solar panel to your next festival.

Frequently Asked Questions

Actually, any battery from Undertwok will give you good phone charging. The truth is that you will find so many other devices and gadgets which you can bring with you – especially if you’re travelling in a van or car – which can really add to the festival experience, from speakers and projectors to cookers and fridges. Yes, really. Cold beer when you need it.

Unfortunately, a portable battery and a portable solar panel may be seen as objects of desire and may tempt some people to borrow them without your explicit permission. There’s no easy way around this: keep an eye on your valuables and be cautious. It may simply not be right to leave a portable battery or solar panel unattended in a tent so do think this through before you commit.
