The Welch Allyn Lithium-Ion (Smart) Handle is just half the weight of current 3.5v handles. It averages 120 minutes of on time between charging. It has the smallest diameter of any 3.5v power handle on the market. The textured handle is made of sturdy CYCOLOY resin. It comes with a low-battery indicator and lithium-ion battery technology that has no "memory" effect. It has a soft-grip rheostat intensity control, and AC charging module with retractable prongs that is easily removable from the handle.
Overall, I like this better than the traditional metal handle with the rechargeable battery. The lithium ion handle is a little bit smaller in diameter than the traditional handle and is lighter in weight. It was also very easy to recharge.
