AC adapters
Message #1 Posted by Keith Beyer on 1 Apr 2007, 9:09 p.m.

Is there a source that lists which HP AC adapters works with which HP calculators? I know individual adapters work with multiple calculators, but I'm clueless which is which.

Thanks!

Sure, there's a source -- this very website, of which the Forum is only one part. Load the home page and do an automated search on "chargers". You just might find something...

Now, a word of caution: What was produced are generally AC-powered chargers for rechargeable batteries, not AC "adapters". As a general rule, a functional battery pack must be installed in the calculator for the charger to be used without damaging the calculator.

An exception is the HP-71B AC adapter, which does not attempt to recharge installed batteries, since it uses disposable cells.

Maybe I should be more specific. Does the AC adapter that works on an HP 97 work on an HP 71B? I know there is a list on the Museum website of batteries/chargers and which calculators they work with, but will none of these work with the 71B?

Thanks!
