We are getting more and more questions about USB 3.0 ports/cables so we wanted to put together a Q&A for you!

This is a running list, so if you have any other questions, please don’t hesitate to leave a comment below.

Before we get started, here is a brief video of an overview of what an USB 3.0 cable does:

Question #1: I’ve heard about phone batteries being able to charge faster these days. Will a USB 3.0 cable charge my phone faster?

Great question! Time is one of the most important resources we have, so if we are given a tool to save us time, we are all over it. USB 3.0 actually have the ability to charge your mobile devices 2x times as fast. You read that right! A charge that takes an hour can now be done in 30 minutes! There is a catch, though. It’s not your battery that causes faster charging. It’s not even the cable that causes it.  It depends completely on how much electricity is being sent out (output). I could bore you with technical jargon but this would be the last sentence you read… That is why this analogy will help (this is a simple analogy so please excuse the mathematical inconsistencies):

The original output will be cars being added.

The USB 3.0 cable will be the lanes.

Imagine driving down a two-lane highway.  There are 20 cars being added to this road each second. The average speed is 50 M.P.H.  A mile into your journey, you approach a merge.  This adds 20 more cars to the 2 lane highway each second. What do you think happens? Yep… the average speed slows down. You now have twice as many cars in the same amount of space so this shouldn’t be shocking.  What happens if 2 lanes magically appear right when the merge happens? Theoretically, there shouldn’t be any difference in the original average speed of 50 M.P.H. since twice as much space was created when twice as many cars were added.

So what does this analogy show? If you look between the lines, you realize that everything is dependent on how much original output is created.  If you only have 20 cars being added each second, the flow of traffic (theoretically), won’t increase even if lanes are added.  If 40 cars are added each second to the same amount of lanes, then the flow of traffic will be slow down unless lanes are added. So the USB 3.0 cable cable helps “increase” electricity transfer if the output is too much for a USB 2.0 cable.

tl;dr (Too long ; Didn’t read): If the electrical output is not too much for a USB 2.0 cable, then there is no point in having a USB 3.0 cable.

Question #2: Ok… So maybe I can’t charge my phone faster. Can I transfer data faster?

This, in my opinion, is the best feature, especially if you have a lot of photos, videos, or files to transfer. With a USB 3.0 cable, you can transfer up to 4.8 Gigabits per second.  Not impressed yet? To put things into perspective, a USB 2.0 cable transfers up to 490 megabits per second. That is almost 20x faster! Data is different than electricity so increasing the amount of lanes (if we are still using the previous analogy,) will help speed things up. Yes, you can transfer data faster IF you have fast internet speed.

Here is a really useful chart from our friends over at

Question #3: Which tablets have a USB 3.0 port?

This list is by no means exhaustive but we will do our best to keep it updated!

1. Microsoft Surface Pro 3

2. Microsoft Surface Pro 2

3. Microsoft Surface 2

4. Nokia Lumia 2520

5. Dell Venue 11 Pro

6. ASUS Transformer Book T100TA

Question #4: Which smartphones have a USB 3.0 port?

1. Galaxy Note 3

2. Samsung Galaxy S5

3. What is your prediction??

Again, this will be a running list of questions so be sure to bookmark this blog post!
