    you are right. my charger i made is capable of 6 A continous. and 12 A peak. even my flip phone charged just fine. this is why when you twist in a lightbulb into that 15-20 Amp socket, it dosen't explode. any usb device by spec will only draw as much amperage as it was designed to handle. (they should be self regulating)

    also, if your 5v outlet is above 500-1500 mA, you should also short the data wires so a device knows it's not possiby a pc and must be a dedicated charger. this way your device will draw a higer amperage and therefore charge faster!

    ok first things first no offense I am doing you to help you. with that being said its not called"E-tape" its electrical tape what if a kid or teenager where to see this and try it be as specific as possible as they dont always know our fancy terms. and the "5 VDC thingy" 3 major thingies wrong here...
    1 by thingy do you mean a 5VDC battery charger, a 5VDC phone see what i mean .....the thingy is a 5VDC adapter, or transformer or power pack
    2 What is the amperage of this "5VDC thingy" if its usb then it should be at least 500 nominal Ma the reasobn being a pc usb plug is rated at that and anything more might burn the usb plug(s) up any thing less and stuff may not work or could overload the plugs
    3. its always (especially with Dc voltage) advisable and safer to soldier and tape or soldier and heat shrink all connections as DC voltage will kill you faster than ac dc generally carries more amperage than ac ....amps kill not volts, though it takes 
    Oh I almost overlooked it how far back should the wires be stripped?
    You have a great idea however you need beeter and more detailed pics and you should really research trival matters like I mentioned above before ever doing an instructable on it .

    All I had was a RS 6.5V charger laying around, so I added a 5V regulator and it works for me.

    I don't get the low rating, how much clearer can this get?

    This might also be a helpful inscrutable to those who use portable USB hard drives and have limited laptop USB ports... plug the power into the transformer and the other into the laptop (of course) which sparks an idea... wonder if my blackberry charger could be a power port....

    ok those corrections would b nice but this isnt the most epic instruct able ever this is for the kid with a phone charger, usb cable, tape and somthing to cut with

    A useful idea, especially for those of us with old PCs and few USB sockets (which are all around the back of the box). Could it be adapted to have several USB sockets in parallel?

    However, as an Instructable it is somewhat lacking - photos would be a major plus, as would correct spelling and terminology so that non-English speakers can use automatic translators to read what is posted here.

    (All that's needed is a quick edit - for instance, replace "ur" with "your", "5V DC plug thingy" with "5V DC transformer" or "5V DC adaptor". What are "co siding cords", and is "E-tape" actually "electrical insulation tape"?)
