Yes u can... this is a Power 2U wall outlet u can install yourself (DIY) and have the capability of charging any 4 devices at once... 2 plugged into the USB outlets and 2 plugged into the power outlets.
Think about how convenient it would be to have an outlet... where u want it... that will allow u to charge 4 things at once. After the 20 or so minutes installing the 15amp outlet, I plugged a camera, cell phone, ultrabook and Kindle in and let them charge... worked like a charm and again, the convenience is great... no more plugging and unplugging wall outlets and using all the USB ports on your PC. I picked the most convenient place where I could place 4 things conveniently on the counter and where all 4 cords reached without a problem. Here are the details from the The Newer Technology web page. BTW, mine is the 15Amp model, but they also have a 20Amp one available.
Charge Four Devices At Once!
Unlike other similar products, the port and outlet layout of the Power2U doesn't create "plug barriers". This accessible design enables you to charge up to four devices simultaneously! (Here is mine with 4 units charging at once!)
Ideal for users of multiple USB chargeable devices, the Power2U AC/USB Wall Outlet is a basic "DIY" install on any 15Amp circuit with a 16 cubic inch electrical box to blend seamlessly into the wall as a standard power outlet. A "straightforward" rated "how to" video demonstrates how the Power2U can be installed in as little as 20 minutes.
Money Saving, Energy Efficient Design Offering a modern, centralized location for charging/powering USB devices, the Power2U offers two energy efficient features to complement its use convenience. The Smart Power design only outputs enough charging power required by the attached device, while spring-loaded Safety Shutters turn power off to the USB ports to eliminate "vampire" energy draw when a connecting cable is removed.
New Slimmer Design for Even Easier Install. The 2013 Power2U model offers a more compact design than previous models for an even easier install.
Install With Confidence. Fully UL-Listed and featuring NEC compliant tamper-resistant AC receptacles, Power2U offers peace of mind confidence. And with its more compact design and free how-to installation video, you can have Power2U installed in as little as 20 minutes!
