Product Description

The Rechargeable Amp Power Pack offers a convenient reusable power solution for select Roland mobile amplifiers that support battery operation, including the CUBE Street EX, AC-33 Acoustic Chorus, and other models. The one-piece design pops easily into the back of the amplifier, eliminating the need to fuss with multiple AA-size batteries. But the benefits don’t stop there — you also get up to twice the runtime over standard batteries, and the amplifier delivers output power and SPL that’s nearly equivalent to using the AC adaptor.*

*Up to twice the runtime is possible compared with eight AA NiMH batteries with 2,450 mAh capacity. Actual runtime and performance can vary with the conditions of use.

Key Features

  • Official Roland rechargeable battery pack for select amplifier models.
  • Easy to install and remove.
  • Longer runtime than using AA batteries.
  • Allows the amplifier to deliver more output power and SPL than what’s possible with standard batteries.
  • Premium design with safe, efficient, and reliable NiMH (nickel-metal hydride) battery.
  • Can be charged with the AC adaptor included with the supported Roland amp model (excluding the BA-330).
