Anyone who regularly works with wireless microphones, in-ears or headsets knows how fast batteries run out. Every year, thousands of AA and AAA batteries end up in the trash. costly, unsustainable and far from efficient. The KLVR Charger Pro offers a smart and professional solution: a reliable, fast and sustainable charging system perfect for extensive use.
At ISE 2025 in Barcelona, NFGD Zoetermeer participated in the contest at the Klvr booth and guessed the exact number of batteries in the tube. The prize: a KLVR Charger Pro with 48 rechargeable batteries. The system has now been in full use and with great success.
The KLVR Charger Pro makes it possible to charge up to 48 AA or AAA batteries at the same time, neatly organized in one compact rack unit. Each battery has its own LED indicator, and the display clearly shows how many are fully charged. With the control button, users can easily select how many batteries they need to charge, after which the system automatically optimizes the charging process.
Through the KLVR control software, NFGD Zoetermeer can monitor the charging process remotely, ideal for larger productions or fixed installations. The charger ensures that every battery is charged safely and evenly, extending lifespan and improving reliability.
The included Lithium-ion batteries provide more capacity than traditional alkaline batteries and can be recharged hundreds of times. Thanks to the built-in chip, equipment recognizes KLVR Batteries as standard batteries, including an accurate display of the battery status. Switching batteries is therefore simple and seamless.
For NFGD Zoetermeer, which works daily with dozens of wireless transmitters and headsets, this brings direct benefits: less waste, lower costs, and greater reliability during productions. Exactly the kind of sustainable and hands-on solution they were looking for.
"After ISE 2025 in Barcelona, I got surprised: I was the winner of the KLVR Charger Pro with 48 rechargeable AA batteries.
For us this is more than just a fun price. We use thousands of AA batteries every year for our bodypacks, headsets and wireless in-ear systems, and we had been looking for a way to reduce that stream. The KLVR Charger Pro really helps us take that step forward.
What's most important is that the battery indicators on our equipment work exactly as they should. The batteries last long and give us the confidence to deliver the quality our clients expect from us at every production. This system is a full-fledged alternative to well-known brand-specific solutions.
With increasing pressure to work more sustainable and efficient, this solution comes at exactly the right time. For us, it feels like a practical and affordable step forward.
Thanks to Triple Audio for the quick delivery and excellent service!" - NFGD Zoetermeer
