Maybe charges AA at 800mA and AAA at 120mA ?

Just guessing that the 1.2V 800mA is the battery rating and the 120mA is
the charging current.

** Printing error - dummy.
The first spec is for intended cell type.

If the power output is at 1.2V, it's charging cells in parallel.
If it delivers 800 mA into a 1.2V load, that's good for six cells in parallel?
The 120 mA could be a per-cell limit, or into a 1.4V -1.6V load (fully-charged cell)

Smaller batteries overheat more easily...

I picked up a AAA NiMh battery charger.
The label reads:
Output: 1.2 V 800 mA
AA/AAA charging: 120 mA
Why the two different current specs?
