Frequently asked questions
A rechargeable unit is often better for repeat home routines because you do not need disposable batteries. A battery powered unit may fit occasional use or backup-power preferences.
Not necessarily. Power source does not guarantee stimulation strength. Compare channels, modes, intensity control, pads, and safety guidance instead.
Check charging method, included pads, channel count, return terms, current Amazon reviews, seller details, and whether the manual matches your intended routine.
