can i plug my iphone into it and use it as a speaker?

Yes, there is a AUX input jack.

I can’t figure out what the trigger does. As soon as I turn it on it stays on. Anybody have info for me?

The trigger is there in case you don't want to have the megaphone on at all times. You can press the trigger to activate the microphone only, all the other functions will not work while pressing the trigger.

Is it loud enough to interrupt a concert?

I’m unsure if it would interrupt a concert, but it’s loud enough to be heard across a heavy traffic intersection

Excellent Megaphone! Very loud! The instructions aren't very clear but once you figure out how to use the battery pack and the volume, it's fantastic! I marked 5 stars but it's only showing 3 but this Megaphone is a great value

Love the colors on this since it does match my crew colors. Besides that the audio and functions on it are kool. It is loud and it includes a siren sound which is extremely loud! It records you and you can play back when u want. This is a must have piece. This is great for street preaching as well! God bless all.

Works great and very loud. Sometimes the mic takes a few seconds to start working but its just a delay on the first try.

I LOVE this megaphone. I love the features, especially being able to record 20 second messages! I love the convenience of the rechargeable battery - the pack just plugs right in! I love that it’s so lightweight but the loudest megaphone I have used! We have used it for summer camp and it’s been EXCELLENT!!! The ONLY issue I have is that the instructions are not clear as to what all the ports are for. It has a USB and the megaphone will charge my phone. But it doesn’t play music through it which is what I was hoping for.
