The Klvr Charger Pro is more than a battery charger, it’s a complete power management system for professional AV environments. Combining high-capacity charging, purpose-built batteries, practical accessories, and intelligent monitoring, it replaces disposable workflows with a reliable and scalable solution.
Charge up to 48 AA or AAA batteries in a single 1U rack
Built for live audio, broadcast, and AV professionals
Uses 1.5V li-ion Klvr Batteries with a linear discharge curve
Reduces reliance on disposable batteries, and outperforms traditional rechargeable solutions - all while improving workflow
The Klvr Charger Pro is a purpose-built power solution for demanding professional environments. Designed by touring engineers and AV specialists, it replaces disposable batteries and fragmented charging setups with a single, streamlined system.
Install it in your rack, load your batteries, and gain full control over your power workflow - from charging to monitoring.
48 batteries simultaneously (AA or AAA)
Equivalent to powering up to 24 wireless devices per rack unit
1U rack format (19” standard) for efficient integration
Compared to brand-specific and proprietary charging docks, Klvr delivers significantly higher density in a fraction of the rack space.
The Klvr Charger Pro is designed to meet the demands of professional audio environments where consistency is critical. Whether you’re running wireless microphones, in-ear monitors, or other AV equipment, it delivers dependable performance to all AA/AAA compatible devices across brands.
Each battery slot is individually monitored, with clear LED indicators providing instant visual feedback. The integrated front display gives you a real-time overview of charging status and estimated time remaining, so you always know exactly where you stand.
No guesswork. No battery swaps mid-show.
Klvr Batteries are engineered specifically for professional use:
1.5V output with a linear discharge curve
Up to 30% longer runtime vs. traditional rechargeables
Rated for 1,200 charge cycles
Quick charging times: Approx. 2h 45m (AA) and 2h (AAA)
Unlike typical NiMH rechargeables, these batteries behave like alkaline, making them fully compatible with existing equipment.
Connect the Charger Pro to your network and get a clear overview of your entire charging setup with Klvr Control. Monitor multiple units, check individual battery levels, and track charging progress in real time.
Available for Mac and Windows, it lets you manage everything from your computer, so your batteries are always ready when you need them.

Built for life on the road and in permanent installs, the Charger Pro features a durable aluminium chassis and a practical drawer system that keeps batteries organized and easy to handle. It slides straight into a standard 19” rack and fits seamlessly into existing systems without adding complexity. Power and network can be daisy-chained via IEC C13/C14 and dual RJ45 connections, making setup clean and efficient.
The Klvr Pouch is designed to keep your battery workflow as efficient outside the rack as it is inside. Built for transport and day-to-day handling, it provides a simple way to store, separate, and carry your batteries between charging, prep, and use.
Whether you’re preparing for a show or collecting batteries after, the pouch helps you stay organized, so you always know which batteries are ready and which need charging.
