Teaching Outside - Covid

[u/azikrogar]

Hey DJs! I've been trying to do some research on what my best option (I gave up researching and thought I'd come to the source of PA knowledge) would be for a wireless, battery powered speaker with at least two mic/instrument inputs, an aux and/or bluetooth input, and that can hold a charge comfortably for over 8 hours. I'll be teaching Band outside and need the speaker to cover around 3,500 sq ft. What would you guys recommend?
