No more disposable batteries

Most disposable batteries used in touring, conferences and theaters are disposed with over 50% of their capacity remaining, resulting in an enormous environmental waste.

That’s not only bad for our planet and your wallet, but for the reputation of the industry as a whole.

Stop the waste. Go rechargeable with Klvr.
