What is the power supply cable connected to most USB hubs called?

I recently bought a USB 7 Port Hub with external power supply, but unfortunately it got burnt out. I have searched everywhere using the keywords that I know but unfortunately can only find diy guides and hubs with supplies. The original cable that came with it is:

The hub is:

AC/DC power adapter or Wall power supply are the most common.

I suggest you contact the manufacturer for an exact replacement.

If not you can possibly match a generic replacement.

4 things that need to match or damage will result.

1. DC voltage

2. DC amps equal or higher

3. Male plug polarity, center pin is either + or -

4. Male plug size measured in Milimeters (mm)(outer diameter and center pin diameter)

If you cannot find one with proper male plug you can cut it off the old one and patch it into the new cord, be sure dc polarity is correct or you will smoke the device.

Example

This is a very generic AC to DC adapter. There is no specific name for it. All further assumptions are based on the pictures you have provided. Any damage or harm that can possibly occur is your own responsibility

The picture you have supplied is showing a standard 5V DC power adapter. The are very common and don't cost much.

To order the correct replacement you will need the following data:

• Input voltage (in your case it seems to be 115 VAC)
• Output voltage (in your case it is 5V DC)
• Output polarity (in your case it is inner positive, outer negative)
• Output current (can't read on the image, but has to be at least what your original adapter specifies or more, within reasonable margin)
• Outer plug diameter (you will have to measure)
• Inner plug diameter (you will have to measure)

Then just go on eBay and look for "5 VDC adapter x.x mm y.y mm" where x.x and y.y are inner and outer diameters in mm and make sure you pick one suitable for the location where you live (USA, i assume). And don't forget the polarity!

Also note, that if you have fried your previous adapter, there might be a fault in the actual hub which will result in too high current and fry any other adapter connected.

You did mention DIY, so let's offer a slightly different solution than the others, which you may or may not be comfortable with.

This adapter's plug is pretty easy to transfer to a different power adapter. Just cut the black cord of the broken power adapter with a scissor, then get the 2 wires out. They will be one red, one black. If there are 3 wires or if the colors don't match, you can abort at this time. All you lost is an already broken power adapter.

Then you need any other adapter which is

1. Also a DC adapter.
2. Has the same voltage, or is no more than 5% off in any direction.
3. Allows equal or more Ampere to pass through than the original adapter. If the power is stated in Watts instead, divide the Watts by the Volts and you get the ampere. Multiply by 1000 to convert from ampere to milliampere.

If you are like me you'll have lots' of old power adapters lying around which belong to devices you no longer use, and one of them might match.

If you found a matching adapter, cut off the plug, look for the 2 red and black cables. Connect them to the 2 cables of the original adapter's plug. Isolate the ends with isolation tape, independently. Then put some isolation tape around the whole thing so that a cat or a child won't pull it apart.

You can now use the adapter.

The advantage of this method is that you can do it right now and don't have to wait for shipping.
