I know some track day people use them as an alternative to having a generator.

is it good to charge battery ?

Tomas - Aldi are selling these units now, however they are for starting cars/ bikes with flat batteries rather than for charging.
Jump start

so is not the best to charge bike battery. optimizer will be better ?

yes

As above, I would say that anything like you describe is a jump start pack with built in air pump, power points etc.

Battery chargers are different. If you regularly don't use the bike for weeks at a time then I'd get a trickle charger. If you only lay the bike up for winter then use it all the time apart from that I'd get a proper charger and remove the battery when you put the bike away for winter and charge it up the day before you get it out again
