## At a glance

- One adapter and a three-way daisy-chain cable are listed as included, allowing one compatible supply to connect up to three pedals.
- The adapter is specified for 9V DC, tip-negative devices and a 5.5mm x 2.1mm plug.
- The stated input range is AC 100-240V, and the total output is rated at 1A.

## Pros

- Three-way daisy chaining can reduce the number of separate wall adapters needed for a small compatible pedal setup.
- The 6.8-foot adapter cord and 1-foot branches give some flexibility in placing connected pedals.

## Cons

- The total output is 1A, which must be shared across connected devices and may not cover the combined current requirements of some pedal setups.

## Before you buy

- The listing gives a 2-year warranty in feature text but also lists a 1-year warranty description. It also describes compatible equipment broadly, including keyboards, while the explicit package contents name only an adapter and three daisy-chain cables. Verify the selected listing and that each device uses 9V DC, tip-negative polarity, the stated plug size and a combined draw within 1A.

## In the box

- 1 adapter (Included)
- 3 daisy-chain cables (Included)
- Keyboard (Check selected pack): The compatibility listing mentions keyboards, but the stated package contents do not list one. Check the selected listing.

## A good fit for

- Guitarists powering up to three compatible 9V tip-negative pedals whose combined current draw is within 1A.
- Buyers seeking a wall adapter with a multi-branch cable rather than a separate adapter for each compatible pedal.

## Less suited to

- Setups whose connected devices together require more than 1A.
- Devices that require a different voltage, polarity or barrel-plug size.

## Customer feedback

Customer feedback generally reports that the supply works, including a mention of powering a Boss GT-1B Bass Effects Processor. Quality impressions are mixed, with some describing it as cheap. That feedback may matter if durability is a priority, while the listed 1A output and tip-negative specification are the practical checks for compatibility.
- Positive themes: Some customers report that the supply works, with one noting use with a Boss GT-1B Bass Effects Processor.
- Mixed feedback: Quality impressions are mixed, with some customers describing it as cheap.

## Frequently asked questions

### How many pedals can this supply connect?
The listing describes a three-way daisy chain for up to three pedals. The total output is 1A, so confirm their combined current draw is within that limit.
### What polarity and plug does it use?
It is listed as tip negative with a 5.5mm x 2.1mm DC plug. Check your device’s requirements before use.
### Does the package include the daisy-chain cable?
The stated contents list one adapter and three daisy-chain cables. The listing’s compatible-equipment claims do not establish that a keyboard or other device is included.
