Numeric keypads are generally quite lightweight, but that does vary a bit. That said, some wired keypads also require batteries to operate. Wired numeric keypads have an advantage in that they are often powered solely through the USB cable, so you are never left scrambling for batteries. This is often in the form of disposable batteries, although some keypads feature rechargeable battery packs. PowerĪll wireless numeric keypads require some form of battery to operate. One downside of wireless keypads is that they require batteries, either disposable or rechargeable, to work. Wired cord lengths can be short, sometimes just 2 or 3 feet, while wireless distances can reach 30 feet or more. With a wireless keypad, you are not limited by cord length, which makes the unit more versatile. While this is often a matter of preference, wireless can provide benefits that a wired keypad does not, and vice versa. Others have built-in Bluetooth or other wireless capabilities. Some numeric keypads plug directly into a computer using a cord. Find out which systems and versions a numeric keypad is compatible with before getting it.

Your numeric keypad will be much more versatile if it has the ability to work with the widest variety of operating systems. In addition, some numeric keypads only work with specific versions of operating systems (usually newer ones). Some numeric keypads work with a variety of operating systems while others are specific to one system, like PC/Windows.

Choosing a wireless numeric keypad (as opposed to a corded keypad) can help cut down on cord clutter.
