The Battery+ toy line from Fun Factory provides flexible power with regular batteries, rechargeable batteries, or a Click 'n Charge cable that can charge rechargeable batteries INSIDE THE TOY (like any rechargeable vibe). With a shape for every type of stimulation, flexible medical-grade silicone and deep rumbling vibrations, these toys do it all, and at a great price. Oh, and did we mention they are THE most powerful battery toy on the market? Add the Fun Factory Hybrid Kit to turn these sweet little guys into an upgraded rechargeable toy! This convenient kit includes 2 rechargeable AAA batteries and one Click n Charge cable to transform any Battery+ toy into a rechargeable one!"
