I have this charger, but I don't know what it goes to. It may be some other HP item and not a calculator. Does anyone know?

Hi Ken,

the 82055A is a DC/DC converter/ battery charger for the 21 (Woodstock) series.

Kind regards


do you also know the input voltage/range? Would it be a car adaptor or something like this?


It is missing the input cord, but it is marked "use 10 - 16 V DC only" I wonder how it was used?


It was the automobile charger/power pack... plugged into the cancer stick ignitor port...

... now with a much nobler utility.
