The SoulBay 12W Universal AC/DC Power Adapter is a switchable-voltage replacement supply built for the low-draw electronics stacked around a desk or entertainment center. A key-tool dial selects 3V, 4.5V, 5V, 6V, 7.5V, 9V, or 12V DC at up to 1.2A (1200mA), running off standard AC 100-240V, 50-60Hz input, so it covers wireless routers, LED light strips, powered speakers, electronic scales, and small fans from a single brick. Eight right-angle tips ship in the box: 5.5x2.5mm, 5.0x2.1mm, 4.8x1.7mm, 4.0x1.7mm, 3.5x1.35mm, 3.0x1.1mm, 2.5x0.7mm, and 3.5mm mono. Before you order, check two things…

Frequently Asked Questions

What voltages can this SoulBay adapter output?

It switches between 3V, 4.5V, 5V, 6V, 7.5V, 9V, and 12V DC. Use the included key tool to lock the dial to the exact voltage your device needs before plugging it in.

Will it power a device that needs 2A?

No. Maximum output is 1.2A (1200mA) at 12W. It suits devices drawing less than 1.2A, such as 500mA or 1A loads, but will not run 2A or 3A appliances like percussion massagers or cordless vacuums.

Which connector tips are included?

Eight right-angle plugs: 5.5x2.5mm, 5.0x2.1mm, 4.8x1.7mm, 4.0x1.7mm, 3.5x1.35mm, 3.0x1.1mm, 2.5x0.7mm, and 3.5mm mono. Measure your port's inner and outer diameter first. There is no USB-C or Micro-USB tip.

Is the polarity center positive or center negative?

Center positive (+) only, and it cannot be reversed. Many guitar pedals and electronic keyboards need center negative (-); using this adapter on one will not work and may cause damage. Check the polarity symbol on your device first.

Can I use it to charge batteries?

No. It is an AC to DC power supply, not a battery charger, so it will not charge cordless vacuums, rechargeable flashlights, or hoverboards. It is meant to run low-power electronics like routers, LED strips, scales, and small fans.

⚡ NOT UNIVERSAL: This adapter provides a maximum output of 12W and 1.2A (1200mA). It works perfectly for devices requiring less than 1.2A (e.g., 500mA, 1A). ❌NOT COMPATIBLE with high-draw appliances requiring 2A, 3A, or higher (such as percussion massagers, cordless vacuums, or large Yamaha keyboards) 🛑 NOT A BATTERY CHARGER: This is an AC to DC power supply adapter. It will NOT charge batteries for cordless vacuums, rechargeable flashlights, or hover-boards
🔌 8 INTERCHANGEABLE TIPS (MEASURE FOR FIT): Includes 8 different right-angle connector plugs: 5.5*2.5mm, 4.8*1.7mm, 4.0*1.7mm, 3.5*1.35mm, 3.0*1.1mm, 2.5*0.7mm, 3.5mm Mono, and 5.0*2.1mm. ✅Crucial Step: Please measure the inner and outer diameter of your device's input port to ensure a secure physical fit. (Note: Not compatible with USB-C or Micro-USB ports)
⚠️ CRITICAL: CHECK DEVICE POLARITY BEFORE BUYING: This adapter is Center Positive (+) ONLY and the polarity is NOT reversible.🚫 Many devices (like electronic keyboards and guitar pedals) require a Center Negative (-) power supply.

Troubleshooting: If it fails to power your item, double-check that your device is Center Positive (+), requires 1.2A or less, and that the tip fits snugly
🔧 TROUBLESHOOTING GUIDE: If your device is not powering on, please verify the following: 1. Voltage: Is the dial locked to the exact DC output required by your device? 2. Polarity: Is your device strictly Center Positive (+)? (It will not work with center negative devices). 3. Amperage: Does your device require more than 1.2A? (If it requires 2A, 3A, etc., this 12W adapter is not powerful enough to run it)
