This depends on the program you are using. Different Modes require different amounts of energy, so your battery will last longer if you are using less energy-demanding Modes, and the other way around.
Based on our testing, a fully charged FlexBeam can be used:
|Preset 1: Red Glow||10 times|
|Preset 2: Dual Wave||8 times|
|Preset 3: Infra Deep||6 times|
A combination of Modes can influence the number of applications you can get before you need to recharge your FlexBeam.
It takes approximately two hours to fully recharge a completely empty battery.
