About CustomVolt Solutions

We believe energy should be simple, portable, and made for people.

We're a London-based startup delivering smart, flexible power solutions - from everyday batteries to off-grid solar setups - with one goal: to help people live and move more freely, with energy they can trust.

We're a small, hands-on team of engineers, makers, and problem-solvers who care deeply about how energy fits into real life - whether it's keeping a campervan fridge cold in the Highlands, lighting up a boat cabin at sea, or making sure your kid’s toy works on Christmas morning.

Why We Exist

Because we’ve been there
Scrambling for backup power during a storm.
Wiring panels on a van roof just before sunset.
Stress-testing a power bank halfway up a hill.

We know the frustration when things fail — and the relief when they don’t.

That’s why we built CustomVolt: to create human-first energy solutions for people who live life on their own terms, off the grid or on the go. We’re still small. But we’re building something that matters. And we’d love to power your journey — wherever it takes you.

As the official UK distributor of LONGSINGX, we work directly with cutting-edge manufacturers while staying grounded in how people actually use energy — day to day, moment to moment.
