You get BOTH! Tested, both work great. AC adapters included. Batteries not included.

#1 Radio Shack 4 Bay Ni-Mh Battery Charger 30 minute quick charge

#2 Rayovac 1-hour NiMH / NiCd Model PS4 changing system. Charges 9v batteries.

Note: The AC Power Adapter for the RadioShack has the beginning of the outer wire crack (see pix)

That crack/split does not affect ability to charge.
