Description
The KLVR Charger Pro is a 1U rack-mountable charger built for professional audio and video — broadcast, touring, theater, houses of worship, corporate AV, and rental. In a single rack unit, it charges 48 AA or AAA Li-Ion batteries simultaneously, with full power to every slot. Every cell, every cycle — no staggered charging, no half-filled banks.
Because the Charger Pro uses standard AA and AAA cells, it’s brand-independent. It works with any wireless microphone, IEM pack, lavalier, IFB, or comms beltpack on the market — Shure, Sennheiser, Lectrosonics, and beyond. Pop the cells in, come back when they’re done: 2h 45m for AA, 2h for AAA. (sold separately)
The chassis is designed to drop cleanly into a production rack. One rack unit, fits next to your wireless receivers, with power pass-through and an integrated fuse so you can loop AC through the rack without extra distro. A network port connects the Charger Pro to Klvr Control, a native Mac and Windows app that auto-detects every charger on the local network and gives you individual, per-battery health monitoring across the whole fleet.
Designed in Denmark, built for the road, and available now through The Penn Group.
