If you’re interested in replacing your old outlets with new ones with USB charger ports, size is something you should pay attention to. USB-enabled outlets have a greater depth than your standard receptacle. This may require purchasing a new in-wall-box to accommodate its larger size.

Duplex vs. Single

USB outlets are offered in several different options:

  • Duplex receptacle with two USB ports
  • Single receptacle with two USB ports
  • Four USB port receptacle

Maximum Amperage:

The amount of amperage that your outlet can put out will determine how quickly your devices will be able to charge. The higher the amp, the bigger the device can be. Each USB port will draw a specific number of amps based on its max amp number. So, if an outlet has two ports and is listed as 4.0Amps, then each port will draw 2A each (unless specified otherwise). Sometimes the manufacturer will specify individual amperages per port.

There are six different AMP options to choose from:

  • 1.0A/2.0A -- Both 1.0A and 2.0A are standard USB ports that are ideal for charging iPhones and Android phones.
  • 3.0A/3.1A -- Both 3.0A and 3.1A can charge medium electronics, such as tablets, and Bluetooth headsets.
  • 4.0A -- These USB charging ports outlets can charge large devices, like laptops.
  • 4.8A -- These USB ports have a maximum power charge up to 4.8 amps, and can be used to charge all USB powered devices from iPhones to Android phones, tablets, smartwatches, and more!
