The digital Wispr contains many circuit boards that are not present in an analog otoscope. Because of this, the Wispr requires a specific level of consistent power.
A large number of manufacturers make power handles that have the common mechanical twist-lock connector used by the Wispr. But, not all of these power handles deliver power in the same way. There are significant variations in voltage, amperage, ramp-time and capacity.
WiscMed engineers have evaluated many industry power handles. Those that have the consistency and dependability as demonstrated by our testing become “certified” to work with the Wispr. You can count on these handles to work with your Wispr.
We also strongly recommend that you have a “fairly new” battery if using a battery power handle. This is because the power that can be supplied by the battery decreases with time. Please see this knowledge base item for battery duration.
We offer a quick, live, and insightful 15-minute demonstration. This is a great way to have any questions answered and see firsthand some of the benefits of the Wispr Digital Otoscope.
