Empowering a Bold Vision: UnderTwoK’s Journey to an Unstoppable Brand
UnderTwoK is a Reading-based retailer specialising in portable, solar-powered energy solutions for creative, off-grid, and everyday use, designed to help people live sustainably with no more than 2 kWh of electricity per day. They stock a curated range of trusted brands, including Bluetti and Jackery. With a strong community ethos, UnderTwoK also hosts events, workshops, and provides hands-on advice, helping customers find the right setup for everything from camping trips to music festivals and sustainable living projects.
The Goal
UnderTwoK needed a sleek, functional website to present its range of solar-powered battery solutions in a way that clearly highlights product differences and brand categories. The site had to support both e-commerce and their growing community presence, providing space for event updates, hands-on support, and lifestyle content. With interactive tools like a runtime calculator and dedicated landing pages for specific audiences, the platform delivers a tailored experience that educates and empowers users to explore off-grid living confidently.
Custom eCommerce Website
We built a bespoke e-commerce platform tailored to UnderTwoK’s unique product range – portable power stations designed for creative and off-grid lifestyles. The store is structured to allow users to shop by dedicated brands, making it easy to browse and compare across different ranges. The design focuses on clarity, ease of navigation, and a smooth purchasing experience, helping customers quickly find the right product for their needs.
Community-Driven Digital Hub
To reflect the brand’s strong connection to its local community and physical store, the website supports event promotion and in-store activities. It acts not only as a shopfront but also as a digital space that encourages customers to engage beyond the products.
Lifestyle Landing Pages for Targeted Audiences
We created dedicated landing pages that speak directly to different customer segments. For example, the musicians’ page highlights the benefits of portable power for touring or street performances, combining storytelling with product recommendations to build relevance and trust.
Interactive Runtime Calculator
To improve product understanding and confidence at the point of purchase, we developed a runtime calculator that lets users estimate how long each power station will run their specific devices. This interactive tool is both educational and practical, helping users find the right solution for their needs.
The Results
We successfully blended e-commerce functionality with a strong community presence. The platform offers a seamless shopping experience for customers seeking portable power solutions, with easy navigation through different specs and brands like Bluetti and Jackery. The addition of lifestyle-focused landing pages, an interactive runtime calculator, and community-driven content has enhanced user engagement, helping visitors better understand and connect with the brand’s mission of sustainable living. The site not only drives sales but also strengthens Undertwok’s position as a trusted source for both products and knowledge in the renewable energy space.
We chose Inter Vivos to design and build and monetise our site. We needed to put our full trust in the team to guide the shape, feel, features and tech stack behind the site. We chose them for their forensic and impassioned approach: they know the details and have strong opinions and viewpoints. The experience of placing our business (the eComm side) in their hands was good they guided us, gave very open feedback, helped us learn and work together. We are very grateful for the leadership and insight they brought to our business.
