Great charge/data cable for travelling...

I ordered this cable mainly for travelling.  It works really well for both data transfer and charging either off of a computer USB port or plugged in using an adapter.  Much easier to transport than the OEM cable.

This little cable is a great travel kit item or for a spare "office" sync-n-charge(tm) cable.
Unlike the one reviewers comment there is (at least now) a light grey hotsync button on the Treo connector.
Not much more to say, it is as advertised, works great, packs small, and allows charging and sync operations without the AC adapter having to tag along. About the only way to improve this would be to make it cheaper or package some free software with it (like a Mac OS X program to talk over the USB port to the Treo in "modem" mode;great for debugging treo programs; great for using the treo as a modem for the laptop).

Cables are good lengths for my purposes and seem well built. Phone charges as it should and is able to transfer data to/from the phone using the cable.

Extremely long cable (almost too long for home use!), charges Android phones nicely, the micro USB connector end isn't chunky so it's good for deep-seated phone cases (Devilcase in my situation). Great for traveling like for airports and coffee shops where power plugs aren't often located conveniently or nearby.

I recently purchased a new MacBook 12" with the newer USB-C style connector (yes, only one) that is used for charging and for data. Since charging is now through a USB port (much like an iPad and iPhone) I wanted to see if some of my other USB chargers and a travel charger would work well instead of carrying Apple's dedicated USB-C only charger. I found this USB to USB-C charging cable and ordered one up to give it a shot. I'm pleased to report that indeed you can charge the MacBook 12" with this cable from just about any standard USB port, though of course charge time will depend on what you are attaching to (USB chargers/port vary in specs from 5W to 10W+). This cable is definitely designed for carrying high currents as it is thicker than most USB cables though not awful.

This handles the charging and data transfer nicely.  Only 3 ports for data though (which I knew going in). The worst thing about it is if you are not leaving your cables plugged in, when you pick the device up to plug in (because it is difficult to just plug in the charging ports while sitting on a flat surface), your data ports may disconnect.

very useful cable, does not take too much space. I use it with my carry-on charger and it is awesome.

Several years ago, I had a retractable micro USB to USB charging cable I got from Monoprice. The only thing I didn't like about it was that it was ONLY a charging cable. It didn't handle data, so I couldn't use it to sync my phone to my PC. Even though that old Monoprice cable still works, I decided to see if I could get a retractable charging cable that could also transfer data. I was pleased to find this Vktech multipack, since it was a great value! I've got one in my laptop bag, one on my Laptop docking station, one in my purse, and I plan to put one in my car, and one in my suitcase, so that I don't have to remember to bring a charging cable when I go somewhere.

The cables charge/sync just fine. Some of the cables retract better than others in the pack, but for the price I paid, I'm not going to complain about that!

Bought it for a trip to England. Worked perfectly to charge my iPhone and a coworker's laptop.  Earned me some Brownie points since coworker was pretty high-ranking and I was the only person who had an adapter.  :-)  Later lent it to a different coworker traveling to England and it worked for him too.

Works great on my computer with high speed data transfers.  Also works great in the car (with inverter) as a multi-device charger (2 phone and 3 tablets stayed charged on my long trips).  I bought a second one for my father-in-law when his old hub died.

Works great!  No connection problems and charges as expected.

These are fantastic and have come in incredibly handy while travelling and at work (where I may not have a USB-C cable available). They support fast charging, assuming the power supply is capable of providing the current, and work with standard USB 2.0 too. I haven't used them for data transfer, as I purely purchased them for charging my Nexus phones.

Excellent little USB to Type-C charging cable. Purchased for my vehicle to charge my new cellphone that utilizes the Type-C (reversible) charging end. Cable is long enough to reach from my center armrest, where I plug it in to a cigarette charger that outputs a higher amp than my Ford Edge is able to produce from the built-in USB port. Cable braiding is resilient and nice. End connectors seem well-built and have not had any issues staying in the cigarette charger or the phone Type-C port.

For those that haven't purchased an electronic device with Type-C yet, I am completely happy with this new technology update. It finally gets rid of the requirement to plug in the USB connector the correct way for charging, as Type-C (which is a type of USB connector) is reversible. Yep, that's right...finally in 2016 we have a USB cable that works either way. Not sure why this took so long to develop, but we've arrived. Next up - wireless charging and flying cars!!! You just wait and see.

Another nice feature of USB Type-C is rapid charging. This cable, when properly supplied with power (more on that in a sec), will charge my cell phone in the car, even when it is running a navigation app and GPS. It does not heat up, it does not kink, it just charges without issue. As for the power required - this is independent of the cable, as the cable is rated for high amps, but you must ensure you USB outlet is able to output the right amount of amps. My poor old Ford Edge has a built-in USB port in the center armrest, but it does not push out enough amps to keep the phone charged while running an app. With a nice little cigarette lighter USB adapter, I was able to overcome this. The adapter puts out 2.4amps per port (2 ports) and that has proven sufficient for my particular Android phone.

Overall, a great cable that does exactly what it says it will do, nothing more, nothing less. I'm not certain if this technology will also be made obsolete in the near future, but for now, a USB to USB Type-C cable is a godsend for these new phones being released.

The 10ft cable is nice when charging your phone or other devices so you don't have to stay pinned to the wall, and it works great for charging. I don't know why some other reviewers would buy as a data transfer cable because there would be too much resistance and pinging would take long making transfers slow. Use as a charging cable because that keeps it powered the whole time with no delay (takes no longer than any other cable.)

If you want a data transfer cable, this is not the product for you, perhaps a 1 foot cable will do for those needs.

This is a great travel charger.  Considering an OEM charger is 3 or 4 times the cost, and requires that you plug it into the wall, this is ideal!  You can use this charger wherever you have a USB port.  So, while traveling, a laptop or vehicle charger works.  Or, as others have pointed out--you can use a powerbank, too.  The charge indicator is a great touch and shows the relative strength of the battery.  Five stars so far!

I use this cable for charging my Nexus 5x in my car. It fits fine at both ends, and permits charging the phone faster than Waze (notorious for power consumption) can deplete it. I have yet to try the cable for data transfer.

This was a perfect Micro USB cable for what I needed it for.  I use it primarily as the data and charge cable to connect my phone (MyTouch 4G) to my desktop computer.  The cable was cheap, shipped fast, exactly the length that was advertised, and charges my phone at about the same rate as the factory USB cable.  Couldn't really ask for more!
