Roland BA-330

The BA-330 carries over Roland's brand of reliability and quality, and packs it all together inside a compact mobile PA system that can be run using regular AA batteries.

And since Roland is well regarded for their portable amplifiers, it is only expected that this battery powered PA has done well in the market.

This system packs a 30W amplifier with 4 channels and 2 mic preamps, that drive a specially designed speaker system with four 6" drivers and two tweeters.

Other features include aux input for your media player, and an intuitive easy to use EQ control.

Users who rely on this unit for delicate outdoor events like weddings and birthdays have many good things to say about the BA-330. There's even one user who reports using the Roland BA-330 for over a decade, and is still very happy with how it sounds. The ability to use regular AA batteries makes battery drain almost a non-issue (with enough backups), and for this many users are very appreciative, thanking Roland for saving them from having to lug around hundreds of feet worth of cables.

Since this unit is dated compared to more recently released ones, there are some who notice the lack of features, specifically Bluetooth connectivity which is a must for some these days. Other than that, most are quite happy with hope it performs.

If reliability is at the top of your list and you want a battery powered mini-PA system that you can depend on at critical moments, then invest in the Roland BA-330.

Although this was previously on our recommended list, there are now more modern and more highly rated options available which you can see in our guide to The Best Portable / Compact PA Systems + Battery Powered PAs.
