It's that barbell looking thing with a + and - on opposite ends. If the center "c" shape opens to the -, it's negative polarity! (the + is on the outside and the - is on the inside), buy this adapter. If it's the reverse of that, buy one with the correct polarity.

I saw this and it has every adapter on it plus you can adjust the voltage. Works perfectly and a good price. ### ⭐⭐⭐⭐⭐ works as expected *by A***R on March 31, 2026* works as expected ### ⭐⭐⭐⭐ Great power supply but adapter didn't fit my Casio Keyboard *by N***X on August 20, 2024* I was looking for a power adapter for a Casio CDP100 which requires a 12V 2A non standard negative center pin. This power adapter has the ability to switch voltages which was great and it also comes with a number of connector to fit different hole sizes. Unfortunately the CDP100 power connector hole is very non standard and requires a short connector. This power supply did power the keyboard but slight movements would lose connection. Still rating this adapter high but a different connector is needed for the CDP100. ## Frequently Bought Together - SoulBay Universal Power Supply AC to DC 3V 4.5V 5V 6V 7.5V 9V 12V Multi Voltage Power Adapter with 8 Plugs for Center Negative(-) Tip Negative Effects Pedals Keyboards Instrument - 2A Max - Open Water Still 12oz cans (2 cases, 24 cans) - Sustainable Aluminum Canned Still Water With Electrolytes - 7.0 pH Balanced BPA-Free Ultra-Purified Water --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/80432992-universal-power-supply-ac-to-dc-3v-4-5v-5v](https://www.desertcart.com.ar/products/80432992-universal-power-supply-ac-to-dc-3v-4-5v-5v) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-06-19*
