How we ranked these pedal power supplies
Every pick has at least 100 customer ratings on Amazon and a listing with real specifications. The order mixes two things: how each model compares on the specs below (higher share of the best value in this group scores more), and how widely it is bought. The spec score runs from 9.0 to 9.8 and only compares these picks with each other. A spec the listing does not state is left out and the other specs are re-weighted; a listing with fewer than 2 stated specs is scored at half. We do not test gear in person. Full method.

Buying advice: low profile pedal power supply
Start with outputs: count and voltage
Output count and voltage decide which pedals a supply can run. The X4 has 4 isolated 9V outputs, the CS6 has 6 isolated outputs with switchable 9V, 12V and 18V, and the X8 has 8 isolated 9V outputs. The SOLUTEK supply gives 2000mA across 5V, 9V, 12V and 18V. Count your pedals, check their voltages, then match the supply.
Check current per output before buying
Current per output decides whether a hungry pedal gets enough power. The X4 and X8 supply up to 500mA per output, and the CS6 lists an output current of 500 milliamps. The SOLUTEK supply gives 2000mA. Add up your pedals' current needs and compare the total with the supply.
Match size, weight and power source
Size, weight and power source decide how the supply fits your board. The X4 measures 3.4 inches by 2.75 inches by 1 inch and weighs 0.2 lb, while the X8 measures 5.5 inches by 2.75 inches by 1 inch and weighs 1 lb. The CS6 weighs 1.3 lb, and the SOLUTEK supply is rechargeable at 0.75 lb with a PD 20W fast charger. Compare the size and weight with the space under your board.
Frequently asked questions
What is an isolated output?
An isolated output is a power output kept separate from the other outputs. The X4, CS6 and X8 all have isolated outputs, with 4, 6 and 8 outputs in order. Isolated outputs help keep pedal power separate across your board.
How many pedals can these supplies power?
It depends on the output count. The X4 powers 4 pedals, the CS6 powers 6 pedals, and the X8 powers 8 pedals, one per isolated output. Count your pedals and match the output count before buying.
Do I need a rechargeable pedal power supply?
No, unless you play without mains power. The SOLUTEK supply is rechargeable and lasts 8-10 hours for a 500mA pedalboard, while the X4, CS6 and X8 run on mains power. Pick rechargeable only if you gig without a power outlet.
What warranty comes with these power supplies?
It varies by supply. The X4 and X8 carry a 5-year warranty, the SOLUTEK supply carries a 1-year warranty, and the CS6 warranty lasts a lifetime. Check the warranty term before buying.
