Why is it so difficult to buy N-octave mini keyboards, for various N>2, with a good built-in set of samples?
How many keys do you want?
Something like a Yamaha CK61 would give you pretty light weight and compact 61 note battery powered keyboard with, I think, pretty good samples.
I have the bigger CK88 hammer action version and like it a lot.
Its not? Yamaha Reface.
It's not a ROMpler, but Hydrasynth Explorer.
