Review on Step Up Voltage Converter: Qutaway USB 5V to 9V or 12V Step Up π Cable - Adjustable DC to DC Transformer Converter with Switch - Effective Power Boost Solution (5V-9/12V) by Jason Hymon
High performance (relatively)
I have a 3 tube guitar pedal that draws 775mA at 12V when connected to the appropriate transformer. This runs at 718. A small drop will not affect the signal much. Others I've tried are only half as effective. Highly recommended.
- Satisfied so far
- Some minor issues
