The 203241 AC Cable from Pentax is designed specifically for use with PocketJet II/200 Series or PocketJet 3 Series Printers. This cable must be used to connect the 203235 or 205521 AC Adapter for those printers to the electrical outlet. When used in conjunction with the adapter, this cable allows you to power your printer using a standard electrical outlet and also charges the printer's internal Ni-MH rechargeable battery.
