One main difference between vibrators is the power source for the vibrator. Most vibrators are battery operated and require AA or AAA batteries, although vibrators that take small watch size batteries are gaining in popularity. However most of the original vibrators, and today the best quality vibrators remain electric vibrators. There are also electric models that are rechargeable, so you can use them without a cord, but they must be plugged in to recharge in between uses. Here are some of the key differences between electric and battery vibrators:
- Have stronger vibrations
- Tend to be better quality and have longer lives
- Are primarily for external stimulation (some sex toy makers have designed attachments that can be purchased separately and used for penetration)
- Are generally more expensive
- Available in a wider range of shapes, sizes, colors
- Usually not as powerful as electric
- Compared to brand name electric models, they are not as good quality
- Generally less expensive, available in a wider price range
