I can't think that 10 watts is goingto cut it for much other than home practice, or quiet acoustic sessions.
If 10 watts is enough than look at the Yamaha THR series, which now go up to 30 Watts. I have the THR10 ( Older 10 Watt model) and it's great. Mine will run on batteries and is ideal for "Acoustic" sessions (just about loud enough).
Addendum: The THR30II can also run on batteries.
Another Addendum. Old Roland cube series (up to 120W) are now discontinued and replaced by Thes BOSS cube range, which looks like a very different (Inferior?) product, but the old Roland Cubes are still available in some shops and, of course, second hand.
PS: When I say "inferior" I probably mean "Less useful"
