Mobile DJ/Karaoke Setup w/Rechargeable Speakers

[GwenButler]

Greetings,
Does anyone have any recommendations concerning a mobile DJ/Karaoke setup w/rechargeable speakers configuration?

I am looking to use quality rechargeable speakers (i.e., supports good voice sound) and at the same time, still utilize my powered amp/mixer and laptop.

Is this even feasible?

(BTW- I have invested in an ALTO - Professional Stealth Wireless System for wireless speaker capability, however, I am now trying to replace my need for powered speakers.)

Thanks in advance for any and all advice!
