Power adapters are for more than smartphones and tablets—most electronic devices at home and in the office use one. Power supply adapters charge medical equipment, laptops, computers, POS systems and more. Find AC/DC adapters on radios, electronic keyboards and home decor and health equipment. No matter what type you need, Newegg has the power adapters to energize your work or recreational devices.

Power Adapters That Charge Medical Equipment

Medical devices require power adapters that meet IEC 6061-1 standards. Switch–mode power supplies are common in hospital and clinic settings for patient monitors, ultrasound equipment and feeding pumps. At-home medical equipment like CPAP machines uses AC/DC adapters. Some switch–mode power supplies require separate AC/DC adapters. It is not uncommon to see charging stations for smartphones, laptops and tablets in waiting rooms at medical facilities. Medical facilities may also use data adapters for computer networking systems, especially ones that store medical records. Most adapters that meet the standards for medical equipment are clearly marked. You can also check IEC 6061-1 standards or the manual that came with your home health equipment if you are unsure of correct voltages.

AC/DC Adapters Provide Juice for Entertainment Devices

AC/DC adapters provide electricity for audio, video and charging docks. Portable DVD players often use AC/DC power supplies to recharge batteries. AC/DC and audio adapters work together to help external speakers on computers and other devices produce high-quality sound. Serious gamers or techies may want to consider purchasing charging carts. These carts have a variety of different ports for charging equipment like gaming consoles, mobile devices and computer systems. Power accessories are available for PC and Mac desktop and laptop computer power cords, as well as USB charger cords for mobile devices. You can also choose kits with several power adapters and cords provided, so you always have the right power source on hand.

Charge Home Devices With 12V Power Adapters

Portable home phone charging docks use AC/DC adapters to power rechargeable battery packs and provide power to the bases. Landline phones also use cords with modular adapters at each end to connect phone jacks and phone bases. Most low-voltage home devices like phones, wax warmers and some hair dryers use 12V power adapters, making them the most common adapter for electrical devices. Home office equipment like portable paper shredders, external storage devices and printers all use power adapters.

Portable Adapters Make Charging Devices on the Go Easy

Don't fret if you're traveling out of the country—there are compatible power adapters for outlets in the U.S., U.K., E.U. and A.U. Some portable adapters are plug-in models, while others contain their own onboard rechargeable batteries that you can use to charge devices. Power converter adapters are available that have multiple heads, so you can power nearly any device. Adapter kits often contain interchangeable cord heads with chargers that accommodate multiple voltages that you can switch between.
