Has anyone tested this with longer USB cables? I'd like to find some longer cables that charge at a decent rate.

It works well for testing cable resistance, you can measure the drop in voltage at a steady current measuring at the start and end of the cable with the same load. You can also check the voltage and current with a steady load with and without the cable being tested. Some well made long cables I tested performed much better than generic short cables for charging, appearances could be quite misleading. I found most cables badly affected charging performance especially with higher current draw devices like iPads. It was common to see charging rates drop by more than 30-50% even with shorter low performance cables. Make sure you power the USB Power Meter up for at least three seconds before plugging in the load to give it time to calibrate.

The answer has nothing to do directly with the device. The USB standard specifies a maximum length of 5 meters. Cables longer than 2 meters will cause problems with some devices. To go longer that 5 meters you need a "signal booster" such as a powered USB hub.

Dear Nick,Thanks for your email. The cable from the USB charging port to the receiver was about 3 feet. Please feel free to contact us if you have any problem. We will try our best to help.Thank you.Mpow Support

Hi Sue. I really cannot say for sure if it will work. I can verify though that the specific cable worked without any problems when I had to connect to it another USB cable, both totaling 10 meters in length. I could not achieve USB connectivity in such a distance by any other kind if USB cable used in the past. I hope that this will help you somehow. Nick.

Yes. The usb cord does not appear to be product specific, so there wouldn't be an issue to use a longe one.

I'm not sure what to tell you. Mine has been working great since I've received it. I would recommend this product to anyone. Have you tried a different USB port? Try asking for a replacement, the price is just too good.

I have used numerous different USB chargers and cables (at home and in my work van) and have yet to have any issue with any of them so I can't see why you wouldn't be able to use this particular USB charger.

No it shorts out. And it will not fully charge. I've tried multiple USB cords as well.

The problem isn't the USB cable its the power adapter. I tested first using the one I have for my phone and it charged. Wound up picking up one for 10 dollars at Walmart. Just check the amps on any USB wall plug as long as its 1.5 amps or more should be fine

Yes, I actually use the longer cables available on Amazon.It is a basic cable.

I've found that sometimes you must use the wider, proprietary plug to charge & link. Why the USB-only link fails sometimes, I don't know.

I bought one of these USB cables and it worked for a while then quit working. Other buyers seen to have had the same experience. My advice: buy a different brand.

The science says yes, an extension slows the charge rate. Better made cables slow it less. If personal experiences like the other people who answered the question say no, I'd assume this is a good quality cable and the charge reduction isn't too bad.

since usb works off of dc current a longer cable will cause it to charge slower

Yes, I have been using mine while charging with the USB in my vehicle. No issues.

My usb ports are shot/ shorting out. and I have only had it for about 5-6 weeks. IT turns off without me noticing until it gets too hot, and I have to wiggle the usb just so and hope it stays to get it to work. I am past the 30 day return, so I am SOL.

I have one working, battery holds up fine and is not an issue. The issue is the usb distance, I finally used a usb hub and it started working fine. When plug direct in usb I had problems.

From what I've read, the length limit on USB 3 is about 3 meters. Possibly a special 15' cable would work, I don't know. My cables on these are 6' and work fine.
