NEMA 1-15 Plug

Positive

Plug these adapter cords into a standard outlet and they change AC voltage to DC voltage. These cords use switching regulation, so they produce the stated voltage even when your outlet’s power or the power drawn by your device fluctuates. It also means they won’t get too hot. They have an LPS low-voltage output and Class II shock protection, so if something fails inside these cords, they’ll limit the risk of electrical shocks. These cords meet U.S. and Canadian safety standards as well as U.S. DOE (Department of Energy) Level VI standards for energy efficiency.

When choosing an adapter, match the output voltage and polarity of your device. Look for the polarity illustration on your device or the adapter you're replacing. The current you choose should, at a minimum, match your device. You can choose a higher current, but it will not improve performance.

IEC C14 Input

Couple these adapters with a cord that matches your outlet and length requirements to run DC-powered electronics. Instead of plugging directly into an outlet, the body of these adapters sits on the floor or other surface, so it remains out of the way and won’t block multiple outlets. These adapters use switching regulation—they produce the stated voltage even when your outlet’s power or the power drawn by your device fluctuates. Most have an LPS low-voltage output, so if something fails inside these adapters, they’ll limit the risk of electrical shocks. They meet U.S., Canadian, and European safety standards. Many also meet U.S. and European standards for energy efficiency.

Adapters with an IEC C8 input require power cords with a C7 socket. With Class II shock protection, they have two levels of insulation that prevent electrical shocks.

Adapters with an IEC C14 input require power cords with a C13 socket. They have Class I shock protection and prevent electrical shocks with a combination of insulation and a protective ground.

Swap the plug to match the outlet of the region you’re in instead of using separate cords for each country. These adapter cords convert AC voltage to power DC electronics. Designed with switching regulation, they maintain consistent voltage during power fluctuations and don’t get too hot. They meet U.S., Canadian, European, Australian, New Zealand, and Chinese safety standards.

A limited power source (LPS) low-voltage output decreases the risk of electric shock if something fails inside these cords. Class II shock protection means they have two levels of insulation. These cords meet U.S. DOE (Department of Energy) Level VI standards for energy efficiency when they're in-use, as well as when they're plugged in but not in use.

Choose an adapter cord with an output voltage that matches the voltage of your device. The polarity of the adapter cord and your device must also be the same. Look for the polarity illustration on your device or the adapter cord you’re replacing and pick a cord to match.

USB Chargers

NEMA 1-15 Plug

Power up mobile devices and other electronics.

Unlike many chargers in the market, these are high quality and reliable. All have passed strict U.S., Canadian, or European Union safety standards. Some of these chargers even have an LPS output, so if something fails inside the charger, it limits the risk of electrical shock. Most of our wall chargers also meet standards for energy efficiency when they're in-use, as well as when they're plugged in but not charging. Chargers that use switching regulation produce the stated voltage despite fluctuations in your outlet’s power and the power being drawn by your device. It also means they won’t get too hot.

USB-C chargers are quickly becoming the new standard, often seen on new phones and tablets. Some are USB-C Power Delivery 3.0 certified, so they charge your devices on average 3-4 times faster than standard chargers because they send more power over your cable. 18W chargers will power phones and tablets sold after 2016. 27W chargers will power small laptops. Choose chargers with an output greater than 27W to charge large laptops and other high-power devices.

USB-A chargers have the traditional USB connection. 5W chargers are typically used with small electronic devices such as speakers, routers, and cameras. 18W chargers will power phones and tablets sold after 2016. To charge large laptops and other high-power devices, use chargers with an output greater than 27W.

Chargers cannot be sold to the listed areas due to energy efficiency regulations.

Wireless Charging Pads

Simply place smartphones on these pads to immediately start charging them—there’s no need to remove most cases or plug them into a charging cord. All pads are compatible with smartphones that have Qi technology, so they work with Apple iPhones made in 2017 or later and many Android phones, including the Samsung Galaxy S series. Often used on desks and other flat surfaces, these charging pads make it easy to grab your phone while it’s charging because you don’t have to unplug it.

All of these pads are Qi certified, which means they meet safety, compatibility, and energy-efficiency standards set by the Wireless Power Consortium. They’re CE Marked, so you know they meet strict European safety standards. They’re also FCC compliant to meet regulations for electromagnetic interference.

Style 1 charging pads have a flat surface. A USB cord is included.

Style 2 charging pads have a slanted surface, making it easy to see notifications on your phone while it’s charging. They do not include a USB cord.

Style 4 charging pads can be used flat or propped up with their kickstand, so you can avoid or easily see notifications on your phone while it’s charging. A USB cord is included.

A variety of USB cords and USB chargers are sold separately.
