Helix Syn V produces quiet yet powerful vibration in an ultra-compact, hands-free design and can be used in two modes, powered and unpowered. Slightly larger than the original Helix Syn, Helix Syn V offers a unique experience in unpowered mode with fuller, more robust stimulation. Powered mode introduces 8 expertly tuned, preset vibration patterns at 3 levels of intensity for a total of 24 enhanced sensory experiences, utilizing a simple multifunction button control. Helix Syn V packs a compact but very powerful rechargeable Lithium-ion battery designed to deliver hours of pleasure on a single charge. High speed mode provides up to 3 hours, medium speed up to 4 hours, and low speed up to 6 hours of run time*. Our custom molded charge head fits firmly and securely over Helix Syn Vb s magnetic contacts for simple USB charging. Syn-V-product-charger
