Top 3 Customer Questions & Concerns 🙋‍♂️

⚡ Can I use this for a device that requires 9V 2A? Yes. A device will only draw the amount of current (Amps) it needs. Using a 3A adapter for a 2A device provides extra "headroom," allowing the adapter to run cooler and more efficiently.

🛡️ Is a power cable included with this unit? This unit is the adapter brick only, featuring a standard 3-pin IEC C14 socket. It is compatible with the standard "kettle lead" power cords used for desktop PCs and monitors.

🔌 How do I verify if the 2.5mm tip will fit my device? The yellow-tipped connector indicates a 2.5mm internal diameter. This is slightly wider than the standard 2.1mm pin, making it ideal for devices that require a specialized high-current connection.
