What to know before buying

Listing details to confirm

Listing information is contradictory on polarity: the title and one feature state tip negative, while the product specification, package description and other feature text state center positive. Input voltage is also listed as 110 volts in details but AC110-240V 50-60Hz in the specification. Confirm the actual adapter label, polarity, plug size and device power requirements before buying. The listed 36 watts conflicts with the stated 9V and 0.5 A output, so it is not presented as a reconciled power rating.

Power adapter

Who is it for?

A good fit for

Owners of a listed compatible instrument or pedal whose device label specifies 9V DC, no more than 0.5 A, and a matching barrel plug and polarity.
Buyers seeking a single corded adapter rather than a multi-output power supply.

Less suited to

Devices requiring more than 0.5 A or a voltage, plug size or polarity that does not match the adapter.
Buyers who need confirmed polarity or input-range information before purchasing, since the listing gives conflicting claims.

Customer feedback says the adapter works well, particularly with Casio pianos, and highlights compatibility and quality positively. This is encouraging for buyers with matching devices, but it does not resolve the listing's conflicting polarity claims. The aggregate ratings are generally favorable while still including a smaller low-star share, so feedback alone cannot establish compatibility for a specific instrument.

Positive themes

Customers report that the adapter works well, particularly with Casio pianos.
Compatibility and quality are highlighted positively in the supplied feedback.

Frequently asked questions

What output does the listing specify?

It specifies 9 volts DC and 0.5 A output. Match both against the device requirements before use.

Is the adapter center positive or center negative?

The listing contradicts itself. The title and a feature say tip negative, while the specification and package text say center positive. Verify the adapter label and device polarity before connecting.

Will it fit my instrument?

The listing names selected Casio keyboards and guitar effects equipment, but compatibility depends on voltage, current, barrel size and polarity. Check those details on your device.

What is included?

The supplied contents list states one charger.
