I checked out one of the reviews and this is what I found that should answer your question:

"I did run it for 1.5 hours in a series of 30 and 15 minute sessions at varying power levels without charging. It did not lose power over that time, so I expect it will live up to promises of two hours. Thanks to the convenient charging/storage case, this long lasting power is just an added benefit rather than an essential feature---but it's good to know, nevertheless, that the We-Vibe 3 won't quit when you need it most."

That quote was taken from AntiPova's review which you can view here: link

So WORTH every dime! We have never had it run dead during a use and it recharges right after you put it back in the case with the remote! Will become a favorite or very very close!. Not too mention it can be used with other toys or while having intercourse as well
