HP 38C
Message #1 Posted by Paul on 22 Oct 2003, 8:17 a.m.

I have had an HP 38C for about seven years now and had received it as a hand me down. It came with nothing but the functioning chasis, battery door and battery carousel.

I keep hearing about a "charger" for this model in the classified section. Does anyone know what the charger is for? Is it simply a "power cord"?

If in fact it is a power cord, I may make a bid for someone selling the cord or the cord with a non functioning 38C in classifieds.

Thanks for any help you can offer.

All 3X series (Spices, not recent 38 or 39) do use the same adapter. Thje connecter is similar for all models, a long square notch with 2 contacts.

This calculator can even work with the adapter and no battery pack connected.

You will easily find such an adapter by placing an ad on this site or on ebay. I you don't I think I do have a few US models for spare but because of shipping costs consider ebay as a 1st option.

Good luck !

Hey Paul,

Go look under "Battery Packs & Chargers" on the main page for the P/N of chargers for your 38C. The "B" model chargers are preferred; per the manual (I've got a 38C, too) the "A" models won't harm the calculator but may clear the continuous memory. The manual also warns to not operate the calculator via charger without a battery pack in place. There's been plenty of discussion on the Forum on this topic before.

You should be able to score an applicable charger on eBay for $20-30 - that's what I did last year.

Actually Spice series chargers can still be had on Ebay for $5-$10 if you are willing to do some hunting. The "B" series chargers are best for the continuous memory models (otherwise you can lose memory when plugging the charger in).
