The ProTechTrader Universal AC/DC Power Adapter with Multiple Voltage Output (3v-12v) allows you to easily replace your old wall wort transformer and provides the flexibility to use it with multiple devices featuring 8 interchangeable DC tips, with compatibility for 1000s of small electronic devices. This can save you a lot of headaches finding the correct plug.

The new upgraded model includes a USB port built into the base for the convenient charging of your Apple iPhone, iPad, Samsung Galaxy Smart Phones, and other Android smartphones & tablets utilizing the industry standard 5 volt USB charging ports. It also features reversible tip polarity, allowing for both Center/Inside Positive (+) Outer/Outside Negative (-) and Center/Inside Negative (-) Outer/Outside Positive (+) settings by simply removing the tip and placing it in the opposite position. This allows for maximum device compatibility as it can be set to operate in both center tip positive and center tip negative polarities.

It is important to verify your device's power requirements match the possible voltages available and plugs included with this item before purchasing, as not all electronics will be compatible. The voltage is easy to change by the switch on the side of the adapter, but be sure you're using the correct voltage and polarity for your device before plugging it in. If you are unsure, please use the "Customer Questions & Answers" section below before purchasing and provide your product brand, model, and part number if available, and we will try to help verify your device's power requirements.

This multi-voltage 12 watt (12w/1-amp) replacement switching power adapter supply is compatible with 1000s of small electronic devices requiring 3 volt, 4.5 volt, 5 volt, 6 volt, 9 volt, or 12 volt up to 1.0a or 12 watts, including many Electronics, Tablets, Routers, Smart Phones, Speakers, Monitors, TVs, LCDs, Cameras, and other USB Port Charging up to 12watt 1000ma with a US 120 volt Plug.
