Cordless replacement of Hitachi Magic Wand

I love my old Hitachi Magic Wand - I am on my 2nd already - except that the cord is often really in a way and a new, younger guy I have been seeing gently pointed out there must be a bit more tech advanced options available right now - I generally love Hitachi Magic Wand, use it only on a lower, but still extremely powerful setting, don't need any bells and whistles just want this basic, but a very powerful vibes in a cordless, ideally also smaller option. I don't mind to paying for quality the cheaper toys I bought of Amazon lately do absolutely nothing for me, so I want make sure that a new cordless want will be powerful enough since these are typically non-returnable. Please help a girl out ;)
