Frequently asked questions

  • All of your AA or AAA powered devices! The Klvr Charger Pro is made to work with all devices (like in-ear monitoring systems, wireless microphones, etc.) and brands (Shure, Sennheiser, AKG, etc.)

  • When you buy a charger with batteries at IKEA (or similar), they are 1.2V and after only a few cycles, your devices will measure a ~80% battery charge. The Klvr Charger Pro comes with custom 1.5V batteries with a much smoother discharge curve, similar to the battery packs you’d buy from the device brand, only in the AA and AAA form factor.

  • These chargers and batteries are proprietary, meaning Sennheiser battery packs won’t fit in Shure devices or chargers and vice versa. The Klvr Charger Pro uses standard size AA or AAA batteries that work with all of your devices, regardless of brand. It’s also much more cost- and space-efficient than its proprietary counterparts.

  • When you buy the Charger Pro, you can chose between AA or AAA 1.5V Li-Ion batteries that work perfectly with all your pro audio devices.

  • Contact your local distributor for a price on the Charger Pro in your area.

  • We aim to start shipping the Klvr Charger Pro in early 2025. The exact timing may change based on your location.
