Is it ok to use two of these USB chargers at the same time on one computer?

I think it is ok. I usully charge my camera battery and cell phone at the same time on one computer.

A couple of the answers are not correct.Requirements are:A. one USB 3.0B. USB 2.0 MIGHT require two, MIGHT work with just one (will depend on you port)C. One USB 2.0 and an external power supply (Not included), if one USB 2.0 isn't enough and a second USB 2.0 isn't available.

I've heard the reason for the two USB's is in case you have a computer that doesn't provide enough power on just one USB, then you have to use two. It seems to work fine with just one USB with my Compaq (HP) 6730s laptop. I've also tried in on my HP desktop and it also works with just one USB. My thoughts are, try it with one and if it works, great! If not, then you'll have to use two.

One is for data, on is for power. Depends on your drive and computer. I only had to use 1 USB port and it works perfectly.

Hi Peter Yes, you are quite right. I hadn't tried that but my unit will not do both at the same time. In practice I have a dual USB charger so the need has never arisen. Regards Richard Allan.

If I understand this question correctly: You will be a able to plug in two items, as well as simultaneously plug in two cords with USB.

Haven't tested this one specifically but almost all that have been legitimately tested that are similar to this one have 2.4 total so if you have one item plugged in it will draw up to 2.4 a. If you have two plugged in the unit will allocate the 2.4 amps between both items but no more. There are plenty of chargers out there that will deliver a full 2.4 amps to each usb port but they are a little more expensive.I hope this helps and good luck!Chris

The way I've done it is just plug a USB cord into each of the two ports. One USB is a higher charging power than the other. I've had good luck charging two things at once.

Yes, there are two USB 3 ports. These are the only 2 usb ports available. Note that the usb ports are situated close together. So, if you plug in a usb device that is relatively large, you may not be able to use both usb ports at the same time.

Looks like this price is only for one device---and yes, you do need two of them. I think they work on any computer.... I went to eBay and got a set of two plug links at a great price. (sorry Amazon)

Hello, yes you can charge 2 devices simultaneously. If you only use the blue 2.1A output, then the output current is 2.1A; and if you only use the 1A output, then the output current is 1A; if you charge 2 devices simultaneously, the total output is 2.1A.

Yes, I regularly charge two devices simultaneously. Great little device, turns two wall plugs into three, plus the two USB ports as well, all active at the same time.

Yes, with two USB cords you can charge both devices. I personally wouldn't expect to get to 100% charge for both, though.

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.

You need to plug both USB ends. This way, your external HDD will draw more power than from a single USB 2.0 port.

I can charge one at a time with the attachments provived.But I wonder if you can use a y-connector type device at the larger usb end
