This can't happen despite the alarming warning. USB cables are defined as a master slave configuration and the connectors are different on each end. The power source is the master the other end is the slave. The Leviton wall plug is the master as are the ports on the laptop. There is no master/master cables so the scenario can't happen.

Everyone relax, come on out of the bomb shelters. The sky is not falling today. The Mayan's were wrong.

usb outlets?


I have several male A to male A USB cables. I use them for media upgrades on Ford's Sync system. It took awhile to find them locally tho. They are identical on both ends and 4 feet long. One end into the car, the other into my laptop for software/application updates.

I've found that on cars equipped with USB ports, most of them cannot charge a tablet. They will charge smartphones, though. I've had several complaints that folks can't charge their iPads in the car from these ports. Previous to this I was unaware that there are 2 different current (power) levels for USB ports.

I'm looking at getting a few of these outlets too, so I've been following the posts about them. I don't care so much about charging my iPad off of them, although it would be convenient. It would be nice to have at the kitchen counter and next to the nightstands for our phones, though.

The model made by Leviton (as well as those by Pass & Seymour and Cooper Arrowheart) is capable of charging an iPad or other tablet. They just can't do two tablets at once. The one by Cooper is nice because it's got a duplex receptacle in addition to the 2 USB ports where Leviton and P&S only have a single receptacle. That said, the price point is a bit higher and most people, so far, don't seem to mind the single receptacle so we stock the P&S model at our shop and they sell like crazy.

The one you pictured is the Newer Technology Power2U unit. It is rated at 5.2v, 2000ma, (10w), equivalent to an Apple ipad wall charger. They do work good, we sell them and have never had a problem/complaint, but they are a very tight fit in a standard single gang box and require min. 16ci or larger.

I was wondering about the size... Figured they'd be a bit bigger due to the power supply for the 5v out. I'm heading to Menards in a few hours for some other stuff so I'll have to check them out. Thanks for the heads up on the box size.

Same size as a GFCI outlet, or Surge protector outlet.
