Strong, rechargeable, and holds a charge for hours

I love my Hitachi MW but ...

I want to find a vibrator that is as strong, rechargeable, and holds a charge for hours. I'm thinking of the Jimmy Jane Form 6 or something by Lelo. I would love any suggestions, especially if you've used the HMW.

There is an equivalent to the Hitachi which is rechargable so you dont need the wretched cord but I dont think it is just quite as powerful

Thank you Garts. What is it?
