The core of PowerUP's product range is its UP series of portable generators, which run on compressed hydrogen and produce zero emissions, minimal noise and almost no heat signature, properties that make them particularly suited to military forward-operating units where conventional diesel generators create acoustic and thermal exposure. Products span from the 400 W UP400 designed for personal field equipment charging up to the 10 kW UPMobile trailer-mounted unit for tactical operations centres.

PowerUP's generators have been tested by NATO's Energy Security Centre of Excellence, receiving a highly recommended evaluation, and were deployed during NATO's Steadfast Defender 2024 exercise involving 90,000+ troops from all 32 allies. The company has also validated its systems in active deployment in Ukraine. Customers include telecom operators Tele2 and Telia, as well as industrial and commercial clients across Europe and beyond.

In November 2025, PowerUP closed a €10 million Series A round co-led by dual-use venture firms Mercaton and ScaleWolf, with Estonia's SmartCap Green Fund also participating. The funding is directed at expanding sales teams, establishing hubs in Central Europe and North America, and developing higher-density fuel cell models.
