12W Power Supply Spec.: Input: AC 100-240V, 50-60Hz, DC output: 3V, 4.5V, 5V, 6V, 7.5V, 9V, or 12V 1.2A(1200mA Max), ✔️ Only for 3V-12V DC ≤1.2A Devices; Use the included key tool to securely dial in your required DC output; Warning: You must lock in the correct voltage before plugging the adapter into your device to prevent functional failure or damage;
⚡ 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. Using this adapter on a Center Negative device will not work and may cause damage. Please locate the polarity symbol on your device before purchasing
✅ SPACE-SAVING REPLACEMENT & SUPPORT: Replaces a drawer full of cords for low-power household electronics like LED light strips, wireless routers, electronic scales, and small fans. Backed by a 12-Month Warranty and 30-day return policy. 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)
