Common Questions

What are the dimensions of the power adapter and cables?
The package dimensions are 24.0 x 18.5 x 5.0 cm. The main adapter cable is 90 cm long. For the 1-to-3 variant, adjacent output heads are spaced 25 cm apart, and the tail output to input head is 45 cm. Exact cable lengths for other variants are not specified.
What is the connector type and polarity?
The adapter uses a DC5521 connector with center negative polarity (inner negative, outer positive). It outputs 9V 1A (1000mA) and accepts input 100-240V AC.
What is included in the box for the Us Plug 1-to-3 variant?
It includes a 9V 1A power adapter with US plug and a 90 cm main cable, plus a 1-to-3 daisy chain extension cable with DC5521 connectors. A noise reduction ferrite ring is built into the adapter.
Is this power supply suitable for high-current pedals like digital delays?
No, it is not recommended for pedals that require more than 1A of current. It is designed for standard single effects pedals or compact multi-effects units that draw up to 1A total. Also, it is not for pedals needing different voltage or center positive polarity.
What is the typical shipping time and process for international orders?
This item ships from China. Delivery typically takes 7–30 days depending on the shipping tier. During checkout, orders require human approval, which may add a slight delay.

## Identity
9V1A DC power adapter with noise-reducing ferrite core for single effects and multi-effects pedals. Input 100-240V, output 9V 1A, polarity center negative, DC5521 barrel connector. Includes a daisy chain extension cable (1-to-3/5/6/8). Cable length 90cm; adjacent outputs 25cm apart, end to input 45cm.

## Target persona
Guitarists and musicians using multiple effects pedals (stompboxes) who need a reliable, low-noise power supply for their pedalboard.

## Use cases
- Powering 3-8 single effects pedals on a pedalboard
- Reducing electrical hum/line noise in signal chain
- Replacing a noisy daisy chain or wall wart power supply
- Powering compact multi-effects units that accept 9V 1A
- Setting up a home studio or practice rig with multiple pedals

## When NOT to recommend
- High-current pedals requiring >1A per unit (e.g., digital multi-effects, large pedalboards)
- Pedals needing other voltages (e.g., 12V, 18V, 48V) or center positive polarity
- Users outside US requiring different plug types (only US plug included)
- Buyers seeking fully isolated power outputs (this is a daisy chain, not isolated)
