Rechargeable or Battery Powered Vibrators consume a lot of power, particularly if they generate powerful vibrations.
Rechargeable vibrators, such as FORM vibrators, will cost a bit more as an initial purchase, but can save you considerable money over the lifespan of the product. They also have environmental benefits, keeping batteries out of landfill.
Battery powered vibrators generally cost less as an initial purchase, and can be very convenient for travel as no charger is needed. If the vibrator is efficient, this can be a great option. LITTLE SOMETHING and LITTLE CHROMA can run for over 16 hours on a single AA battery – that's a lot of vibration.
