If you are unable to determine the polarity specification, please contact the manufacturer of the device you want to use this power adapter with. Please note: When testing this power adapter, you must test with a load as this is not a regulated power supply. The no-load voltage will be 1.5x higher than the selected voltage in order to have sufficient current output (this is due to the circuit inside, it is a diode bridge rectifier filter circuit, so the output voltage is higher than the specified voltage when testing without a load ). Once the power adapter is connected to a device that is using power, the power adapter will provide the voltage you selected. If there is an issue, the capacitor storage may need to be discharged before showing the correct reading. Review: Great - This was needed for a wind up radio we have. The cord works great. Very happy. Review: Poor components - Had this for 2 weeks before adapter started giving off an odor. Took it apart and transformer was burning up. Keyboard it was plugged into was barely used/ at correct voltage. Cheap stuff, would not reorder. ## Features - 9 watt, 500mA Universal AC/DC Power Adapter - Input: AC 120V 50Hz - Switchable DC Output: 1.5, 3, 4.5, 6, 7.5, 9 and 12V - Polarity switch and 4 foot cord (IMPORTANT: WILL NOT WORK UNLESS POLARITY IS SET CORRECTLY) - 3.5mm OD / 1.3mm ID, 5mm OD / 2.1mm ID, and 5.5mm OD / 2.5mm Barrel Connectors + 2.5mm and 3.5mm DC Mono Connectors + 9v Battery Snap Connector ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00VIL4ZVK | | Additional Features | Polarity Switch, Universal Compatibility | | Amperage | 500 Milliamps | | Brand | EX ELECTRONIX EXPRESS | | Built-In Media | 1 x AC Adapter | | Color | Black | | Compatible Devices | AC-DC Converters | | Compatible Phone Models | Universally compatible with devices using 3.5mm, 5.5mm, and 9v battery snap connectors (specific phone models not explicitly confirmed) Compatible Phone Models Universally compatible with devices using 3.5mm, 5.5mm, and 9v battery snap connectors (specific phone models not explicitly confirmed) See more | | Compatible Power Plug Type | Type A - 2 pin (North American) | | Connectivity Technology | DC Barrel | | Connector Type | barrel connector | | Current | AC | | Current Rating | 0.5 Amps | | Customer Reviews | 3.6 out of 5 stars 13 Reviews | | Enclosure Material | Plastic | | Included Components | 1 x AC Adapter | | Input Voltage | 120 Volts | | Main Power Connector Type | 2 Pin | | Manufacturer | ELECTRONIX EXPRESS | | Mfr Part Number | 16DMUVL | | Model Number | CR-500 | | Mounting Type | Wall Mount | | Number of Items | 1 | | Output Current | 500 Milliamps | | Output Voltage | 12 Volts (DC) | | Portable | Yes | | Power Plug | Type A - 2 pin (North American) | | Power Source | AC | | Special Feature | Polarity Switch, Universal Compatibility | | Specification Met | ma | | UPC | 753807179492 | | Wattage | 9 watts | ## Images ![9w, 500mA Universal AC/DC Power Adapter 1.5, 3, 4.5, 6, 7.5, 9 and 12V DC with 4 Foot Cord by Electronix Express - Image 1](https://m.media-amazon.com/images/I/71Y3dgNWjyL.jpg) ![9w, 500mA Universal AC/DC Power Adapter 1.5, 3, 4.5, 6, 7.5, 9 and 12V DC with 4 Foot Cord by Electronix Express - Image 2](https://m.media-amazon.com/images/I/81lm-f8S-aL.jpg) ![9w, 500mA Universal AC/DC Power Adapter 1.5, 3, 4.5, 6, 7.5, 9 and 12V DC with 4 Foot Cord by Electronix Express - Image 3](https://m.media-amazon.com/images/I/81hiZE8r8qL.jpg) ![9w, 500mA Universal AC/DC Power Adapter 1.5, 3, 4.5, 6, 7.5, 9 and 12V DC with 4 Foot Cord by Electronix Express - Image 4](https://m.media-amazon.com/images/I/71sVnEHTLfL.jpg) ![9w, 500mA Universal AC/DC Power Adapter 1.5, 3, 4.5, 6, 7.5, 9 and 12V DC with 4 Foot Cord by Electronix Express - Image 5](https://m.media-amazon.com/images/I/812xrfJ2TTL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great *by R***D on July 8, 2024* This was needed for a wind up radio we have.
