About Solus Power

Solus Power, established in 2020 by CEO Stas Leonidou, is a London-headquartered company specializing in mobile energy solutions aimed at overcoming electric vehicle (EV) charging infrastructure limitations. The founder's direct experience with the scarcity of functional public charging points in London for his own family's EV inspired the company's core mission to mobilize electricity, much like a power bank for a phone. Solus Power operates in the energy and defense sectors, providing portable power solutions for both civilian and military applications.

The company's business model centers on the design, development, and sale of its proprietary portable battery technology. Revenue is generated through sales and strategic partnerships with commercial customers and defense organizations. A key milestone was the successful closing of a £22 million (US$28 million) investment from Dubai-based Petra Equity Partners in June 2024 to accelerate technology development. This followed earlier backing from US investment firm Marbanc International and the launch of a Series A funding round in March 2025 with a target of £5 million. The company's strategy includes forming a robust manufacturing and supply chain to produce its units at scale.

Solus Power's flagship product is the 'Kratos' power unit, a military-grade, ruggedized, and portable Lithium-ion battery pack dubbed the "Jerry can of electricity". Each unit is roughly the size of an attaché case, weighs under 25kg for portability, and is designed to be discreetly placed under vehicles. The core benefit is providing off-grid, DC-to-DC rapid charging for EVs, drones, and other electrical equipment in any location. A unique selling point is the modular and stackable design; multiple Kratos units can be connected in series to scale the energy capacity based on user requirements. The company has also developed a higher-capacity technology called 'Titan' for fleet operators and car hire companies who face challenges with grid connections.

A significant aspect of Solus Power's strategy is its dual-use technology application, targeting both commercial markets—such as car parks and rental agencies—and the defense sector. The company has a Memorandum of Understanding (MoU) with QinetiQ, a major UK defense technology company, to adapt its charging solutions for military use in challenging environments. This collaboration focuses on providing reliable power for an increasing array of electrical military equipment and supporting the shift to electrified fleets, aiming to enhance operational advantage and energy self-sufficiency. The technology has been validated by the UK's Ministry of Defence, winning the 2024 Defence and Security Accelerator competition.
