Who wouldn't like to charge their phone, I-Pad, I-Pod, etc. from an outlet?

Dick - You don't have to wait.  That was my first question of the techie I spoke with at the company.  She said that the 5w was irrelevant.  Just because someone's charger might be 8 or 10 watts, this will charge them just as quickly if not more quickly.  I don't claim to know the physics behind it, I just will take her at her word for now.  Everything I charge is of higher wattage as well.

The way I thought of it was this, when I connect a USB to my laptop to charge, say, a phone, the laptop will charge it, but very, very slowly and never to full.  On the other than, if I put the plug into the wall and the USB into the plug (for my Android), it charges much. much more quickly.  The tech rep. my experience would be the later and that it would be true of all products I charged.

We'll see - as I said - I'll give you a full report when they come, and it I sure hope it is tomorrow.

Just to diminish my own ignorance regarding the devices in question, here is what Wikipedia says about USB in the "Power" section: 

(Before you read it, it basically says that USB 1 and 2 are only throwing of 5V no matter what (or, a range from 4.75 to 5.25.)  Load is 100 mA in USB 2.0 and 150 mA in 3.0.  So, I think that's the issue here.  I think we have to worry about how many milliamps we have in our battery, and how long these wall-outlets will take to charge them.  The one thing that gave me certainty is that was certified USB 3.0 and I knew that the 3.0 was much more powerful than prior generations.   My Android phone has 1300 mA while a little backup phone I have has only a 800 mA battery.  It charges very quickly with any connector on any device - and takes weeks to drain.  The Android, well, it doesn't take too long to charge, but it surely doesn't take too long to drain either.  Here's the Wikipedia answer which leads me to say that if we've been using USB at all in the past, it will work on our phones and other devices in the future.

Power

The USB 1.x and 2.0 specifications provide a 5 V supply on a single wire from which connected USB devices may draw power. The specification provides for no more than 5.25 V and no less than 4.75 V (5 V±5%) between the positive and negative bus power lines. For USB 2.0, the voltage supplied by low-powered hub ports is 4.4–5.25 V.^[34]

A unit load is defined as 100 mA in USB 2.0, and was raised to 150 mA in USB 3.0. A maximum of 5 unit loads (500 mA) can be drawn from a port in USB 2.0, which was raised to 6 (900 mA) in USB 3.0. There are two types of devices: low-power and high-power. Low-power devices draw at most 1 unit load, with minimum operating voltage of 4.4 V in USB 2.0, and 4 V in USB 3.0. High-power devices draw the maximum number of unit loads supported by the standard. All devices default as low-power but the device's software may request high-power as long as the power is available on the providing bus.^[35]

Some devices like high-speed external disk drives may require more than 500 mA of current^[36] and therefore cannot be powered from one USB 2.0 port. Such devices usually come with Y-shaped cable that has two USB connectors to be inserted into a computer. With such a cable a device can draw power from two USB ports simultaneously.^[37]

A bus-powered hub is initialized at 1 unit load and transitions to maximum unit loads after hub configuration is obtained. Any device connected to the hub will draw 1 unit load regardless of the current draw of devices connected to other ports of the hub (i.e. one device connected on a four-port hub will only draw 1 unit load despite the fact that all unit loads are being supplied to the hub).^[35]

A self-powered hub will supply maximum supported unit loads to any device connected to it. An externally-powered hub (battery or DC converter) may supply maximum unit loads to ports. In addition, the V_BUS will supply 1 unit load upstream for communication if parts of the Hub are powered down.^[35]

In Battery Charging Specification,^[38] new powering modes are added to the USB specification. A host or hub Charging Downstream Port can supply a maximum of 1.5 A when communicating at low-bandwidth or full-bandwidth, a maximum of 900 mA when communicating at high-bandwidth, and as much current as the connector will safely handle when no communication is taking place; USB 2.0 standard-A connectors are rated at 1.5 A by default. A Dedicated Charging Port can supply a maximum of 1.8 A of current at 5.25 V. A portable device can draw up to 1.8 A from a Dedicated Charging Port. The Dedicated Charging Port shorts the D+ and D- pins with a resistance of at most 200 Ω. The short disables data transfer, but allows devices to detect the Dedicated Charging Port and allows very simple, high current chargers to be manufactured. The increased current (faster, 9 W charging) will occur once both the host/hub and devices support the new charging specification.
