Is it safe to use on a computer's USB port that

Yes, and charge the phone like 3 times faster. I have been use it for like a year and everything still working excellent.

I would say, in general, stay away from it. It caused my external drive to malfunction; and it didn't cause a significant power boost anyway.

It doesn't matter. It will work fine on any USB port (regardless if it is 2.0 or 3.0).

Haven't tried it, but I would suspect so. It acts like a standard USB interface device (I have used it on Windows Vista and Linux based systems).

I've used on an old laptop and two newer laptops. It's as easy as plugging into the port! In my opinion, even though I've only tried on three, I think there would be no problem.

I really do not know as I have not tried using the USB ports, neither do I have the intention of using it any time soon. Sorry that I couldn't help with your question.

As long as you have the port (an any PC or laptop does), you shouldn't have a problem. This unit works just like one that comes already installed IN a computer. My hybrid laptop/tablet didn't come with one. So, I purchased this unit. No problems since.

There is some protection there. As long as you aren't trying to deliberately jam something in there, it would be tough for something to hit the USB port.

As long as your computer features an SD card input, it should be a pretty safe bet. I use one as a hard-drive for a Raspberry Pi and it's been great with no complaints. That being said, sometimes computers and peripherals have weird interactions due to quirks specific to either the peripheral or computer.

No, you can't use the device while it is connected to your computer's USB. You can, however, use the device while it is plugged in to an AC or car power adapter. So just get an AC adapter to charge instead of using you machine and problem solved.

I believe that you can use it in any USB port. It just gonna take the energy from it, no data transfer.

I've used mine on several computers, running windows XP, Vista, 7, and 8. They all recognize it. Just need a working USB port.

Yes it is. Real simple to use too. We just tried it on my Windows 8 computer and as soon as we plugged in the USB it started working.

Yes. You can pretty much use it on any computer or laptop that has a USB port.

My guess is that it will work just fine - plug it into a spare USB port and it does the job. If you want it to stop, just pull it out.

I used the device in both USB ports on my laptop . My laptop is about 5 years old. It worked well.

John we did not take a laptop, so I cannot answer your question. We used it on a tablet and other electron devices. If I were to guess, I would say it is safe for a laptop as they use the same voltage to recharge.
