Critic Reviews

RockBoard launches low-profile ISO Power Block V16 pedalboard power supply | Guitar World

guitarworld.com

The RockBoard ISO PowerBlock V16 strikes a compelling balance between performance and compactness, delivering a robust 3,550mA to power up to 15 pedals alongside USB charging capability. Its low-profile design and individual LED indicators for each output make it user-friendly and efficient for troubleshooting. However, the price point of approximately $200 may deter budget-conscious musicians, and while the number of outputs is impressive, some players might find the 100mA outputs limiting for high-demand pedals. Overall, it's a solid choice for pedalboard enthusiasts seeking reliable power without the bulk.

It has potential, but disappoints

I have had this power supply twice, and both times I had to claim the warranty due to the same malfunctioning issue. I works perfectly until it doesn’t. The isolation fails at some point and it starts becoming very noisy when you touch it. Both times it was deemed unserviceable. Since it’s not being manufactured anymore, I got the money back and bought the Power Grid from Friedman.
