Klvr will demonstrate how its Charger Pro solution is delivering cost reduction and performance benefits for live entertainment and pro AV markets at ISE 2026 (Fira de Barcelona, 3-6 February. Stand #5N900). Klvr Charger Pro enables sound engineers and AV professionals in music venues, production studios, conference halls, universities, houses of worship, and hospitality to eliminate the huge cost and environmental impact of single-use batteries.

Antonis Stantzos, CTO of Greek broadcaster Alpha TV, said: We used to rely on 20,000 disposable batteries every year to keep mics and other devices running during live productions it was expensive, messy, and a constant headache for our team. Now we use just over 400 rechargeable Klvr batteries, giving us reliable capacity and long-term cost savings. It's a no-brainer for any broadcaster.

Founded by sound engineers and music artists, Klvr created a rechargeable battery solution that is purpose-built for pro audio environments. Disposable AA/ AAA batteries are still widely used in wireless microphones, in-ear monitoring and other devices because of a lack of feasible rechargeable options and many are thrown away with excess capacity remaining. While proprietary rechargeable solutions from major equipment manufacturers can be costly and incompatible with devices from different vendors, consumer-grade rechargeables aren't adequate in professional environments due to insufficient voltage and reliability.

Our AV team and musicians need total confidence that every in-ear monitor will work flawlessly throughout rehearsals, broadcasts or major concerts, said Trond Hernes, stage manager of the Norwegian Radio Orchestra (KORK). You can't risk using commercial rechargeables when performers are on stage they're far too unreliable and could cause devices to cut at any moment. Charger Pro gives us rock-solid performance and complete visibility into battery life and recharge cycles. Klvr lets us focus our energy on creativity and delivering the best shows, instead of wasting time and money on guesswork and new disposables.

Mikael Svensson, backline engineer at Overkill Backline for artists including Per Gessle and the legendary Swedish pop rock duo Roxette, said: Shipping and travel costs rack up quickly when you're taking kilos of production gear on tour with bands and artists. Charger Pro is light, compact and perfect for touring. The batteries are excellent quality and work across any kind of device, so you're not locked into proprietary products from audio manufacturers. We now do one Klvr battery change for every three we used to with regular batteries, taking away so much cost and complexity from global tours.

Klvr provides a simple, flexible and affordable solution, with a lightweight, 19 rack-mounted charger and high-performance, standard-sized AA and AAA batteries for any device. Klvr's custom 1.5V Li-Ion batteries each contain 1200 charging cycles and a 30% higher runtime than regular commercial rechargeables along with a linear discharge curve and monitoring system to maximise performance and power visibility throughout the full battery lifetime.

Each Klvr Charger Pro rack unit has a capacity of 48 AA or AAA batteries, offering the flexibility to recharge batteries for a wide array of professional devices at the same time. AA batteries recharge in under 3 hours and AAA in just 2 hours. An intuitive front display and user-friendly Klvr Control system enables AV professionals to easily check battery levels, recharge times and adjust settings from connected laptops. Klvr Charger Pro also includes the lightweight, 48-battery capacity Klvr Pouch, streamlining travel and battery transport through airport security or to remote production locations.

Artists, audio engineers, studios and facilities are all too aware of the huge costs of millions of disposable batteries that are used every year," said Stian Sagholen, CEO and Founder, Klvr. Consumer rechargeables aren't good enough for concerts, corporate events, university lectures or live production. AV teams need a pro-grade, reusable alternative that they can rely on in critical live environments. We're seeing a surge in momentum as users see first-hand how switching to Klvr helps them lower costs, simplify their work and deliver better performances on any stage.

The solution has been successfully deployed by a range of organizations and widely available through a growing international distributor network reflecting a surge in demand for cost-effective, professional-grade rechargeables that guarantee high performance in live environments.

Klvr Charger Pro is available to purchase directly or from a range of distribution partners across major global markets. Please visit: https://klvr.no/quote
