"It’s really good for practice but to make it truly portable you also need an external power supply aka 5v battery. There is not a feature to fix the battery to the amp so this is a minor annoyance. It works great under battery power but be advised it can be affected by other electronics in close proximity which causes sound to “break up”. Otherwise extremely versatile and very good."

"A powerful little monster. It only three watts. But it's size makes it so convenient. I have a battery brick that plugs into the back of it. Very portable and convenient. A great practice amp"

"nothing I don't love about this mini amp! Sound is awesome - love the drum machine option - it's small and portable and can run off a battery pack !!!!"
