Power-Sonic

Power-Sonic

Power-Sonic was founded in 1970 by Guy Clum, who began assembling sealed lead acid and nickel cadmium battery packs from his garage to supply local technology companies. The company survived a devastating factory fire in the 1990s and resumed production within 100 days, a rebuild that cemented its manufacturing resilience. Today it operates from corporate headquarters in Reno, Nevada, with additional offices in San Diego, Hong Kong, and across Europe. The firm’s product architecture spans three verticals: advanced batteries, battery energy storage systems (BESS) sold under the EVESCO brand, and EV charging stations. It supplies sealed lead acid and lithium iron phosphate (LiFePO₄) batteries into end markets including telecom, medical systems, data centers, and industrial automation. The EVESCO unit, launched in the 2020s, bundles power electronics and intelligent energy management to provide fast-charging and storage solutions for commercial fleets, ports and airports, and renewable-energy installations. Power-Sonic maintains a direct manufacturing and distribution presence in the Americas and EMEA, with regional offices in the United Kingdom, France, and the Netherlands. Power-Sonic employs a C-suite led by CEO Shawn Mumma, President Brian Crowe, CFO Kenneth Redhead, and CTO JD Johnson, alongside EMEA Managing Director Rene Assies. The company’s timeline notes that its lithium portfolio first powered medical applications in the 2010s, which then anchored development of a broader LiFePO₄ line. In 2025, Power-Sonic unified its brand portfolio to market integrated batteries, BESS, and chargers as a single platform supporting critical infrastructure and sustainable mobility. As a privately held manufacturer with captive R&D and production, Power-Sonic’s structure differs from asset-light energy integrators that outsource hardware. It controls its own battery assembly and supply chain, selling directly to industrial and commercial end users rather than through a fund or investment vehicle structure. This operating-company architecture means its strategy is driven by product-line expansion and geographic manufacturing footprint rather than capital allocation across external managers.
