Ultra high wattage mobile power source, easily generates 30 watts.

• Unique ultra-high performance brushless DC magnetics gives highest wattage output in smallest package. Easily provides 30W to charge BatteryBOS.

• Large diameter rotor results in lower spin RPMs for lower mechanics wear and less noise.

• Larger contact patch because of larger OD means good grip and lower tire contact pressures and stresses. This means less wear.

• The RollerGen pushes against the strongest part of the tire, spinning along a parallel axis. This means correct kinematics with no “scrubbing” as with sidewall bottle generators.

• Rubberized outer ring for good grip in slippery conditions, and less noise.

• Internal high power circuitry protected from the elements.

• Quick-connect mechanism activated by thumb lever. RollerGen will produce zero drag when not charging, un-like old-style hub generators that produce drag all the time. Disengaged will be its normal condition, since this dyno fills up the battery so fast.

• The dyno is not sold separately. It must be used in conjunction with High Tide electronics.
