How well regulated is the output voltage? Do I need a regulator on the output for a 5v USB device?

The output voltage can be adjusted with built-in potentiometer. I did not test for long-term stability of the voltage yet, but it powered USB devices just fine, and charged my phone normally.

USB requirements are 5.000.25 V (pre-3.0); 5.00+0.25-0.55 V (USB 3.0) -- http://en.wikipedia.org/wiki/USB The specs on this product are 5V 4% (0.20V) -- http://www.ti.com/lit/ds/symlink/lm2596.pdf This product is a regulator and meets the UBS power voltage requirements (per specs). Most USB power sources supply 0.5 Amps, some 1.0 Amps. This product supplies up to 3 Amps.

I didn't quantitatively test this for regulation, but did a 'coarse' check and it held the voltage stable over a wider current load than you can consume with a standard USB device (ie, 500mA). So, with these caveats, I'd say it should power the USB device without any problem (certainly within the +/-5% spec for USB). It's a 10 turn adjustment so it's relatively easy to set the output voltage precisely. Bear in mind that the regulator voltage should be set to 5V BEFORE connecting to the USB device. Perhaps putting a drop of nail polish or epoxy on the adjustment screw afterward to keep it from getting knocked off voltage might be safer.

It's actually the DC output to the device from the AC adapter that you want. It is 5V at 600mA. The plug-in tip polarity is positive inside, negative outside.

Well, although other people have said that "any" input voltage between 3.5V-30V is fine (which is true), there are other things to consider when using the device to avoid damage, such as: the voltage ratio should not exceed 3, in example, means you cannot use 3V to go up to 15V, that will be a voltage ratio of 5. Description says it can supply up to 5A but then it clearly says it can operate at 3A with good ventilation, my personal safe threshold for supplying devices is 50% maximum capacity, so I don't ever use it for more than 2A, this rule of thumb always worked fine for me.

Almost all USB ports supply 5V so you should be fine. If for some odd reason your USB port doesn't supply 5V, you can use a USB AC adapter like what is used to charge an iPhone or Kindle Fire.

I use a multi voltage adapter from Wal-Mart. It works great. Just have to make sure to correctly set the voltage and plug the correct adapter onto the connecting lead. The adapter sells for around $14.00 and can be bought with or without a USB socket.

There is an "Input DC 12 volt" plug-in that then connects to a wall outlet. There is also a USB port called "Output:5V."

no, you need the included ac adaptor(is a 12v output), usb is only 5v output.

I would check with Wagan to be sure, but as near as I know the output from any port is standard USB at 2.1 amps. I hear some Samsung devices have problems due to their proprietary wiring of USB.

I just confirmed that the Plugable USB 2.0.4 will power an RPi unit directly. The RPi only draws 5W, so it's safe.

The device itself runs on 5VDC at <2a using a standard micro USB connector. I gave up on finding the adapters for the wall wart and threw it out (one less power supply to carry as well).

The power output looks correct. It should be fine if the diameter of the plug is compatible with your device

Fine as long as the device is plugged into a USB based source that outputs 5 volts

The specs claim it is 1 amp at 5 volts DC. I don't doubt the 5 VDC rating, as that is what USB voltage is supposed to be. The 1A rating may be a little generous; I would be reluctant to put that kind of load on it full time, as it may get too hot & eventually burn up the internal electronics. Most in-car devices don't draw that much current anyway, though. It does work fine with my Garmin 1450 for when I don't need the special traffic update receiver cord (which is most of the time), and the price is right.

Yes, the DC 12V output is the 5.5 mm plug. However, the voltage coming out of that lead can get as high as 18.3 V on a clear sunny day. So you may need a 12V controller/regulator depending on your application. You may also need an adapter if your devices use a car accessory type of connector.

I can't specifically answer the question but written on the adaptor is: Output: 5V--2.0A Max

The voltage on USB charger ports are 5V. That's the standard voltage for all USB ports. Thanks!

I belive the mini USB 5 pin is the same but i'm not sure about the power requirements. Sorry
