The HP Portable and Portable Plus use the same power supply that's used
for most of the HP-IL devices. It's also used for the HP-71 and 75
calculators and the rechargable battery pack for the HP-41. It will also
operate the HP-91, 92 and 97 but their ORIGINAL power supplies are slightly
different. In the US the charger is a HP 82059 but they also make different
versions to match the AC voltages and outlets in most other countries. The
output on all of them is 8 VAC. I don't remember the current but it's about
150 Ma IIRC. Look at

The batteries in the PP and PP+ are a pain. They're lead acid and they
are individual cylinders. So if you let them run down for very long, it
will ruin them and they're not an easy style to find. IIRC they're X size
which is slightly larger than standard D size.
