Great micro-usb cable but the tips have similar issues as others.

So despite being awesome anker cables the heads on these micro-usb cables suffer a lot of the same issues as others.  The contacts stop making good contact after a while and the tip bends easily.  Luckily the market is moving more and more towards usb-c where I think that issue will go away.

I have purchased MediaBridge USB Cables a few times now and I must say I am impressed with the built quality and durability, they charge and Sync my phones and other devices, the cost is amazing for the quality you are getting. I would like to leave some feedback though, the ends of the cable where they attach to the phone eventually end up flat and the cable will not stay plugged into the phone unless left at a flat surface after a few months of usage (see picture attached) that's why I'm removing 1 star from the 5 available ones.

This is a solid unit, compact, sleek. It charges with a  micro-usb plug common to most non-IOS devices these days (rather than the older larger mini-USB). Oddly, it features a 1-LED flashlight and a laser pointer as well. I suppose these could come in handy while camping or something, but since all 3 functions are operated by the same single push button it can be tricky to activate the charging rather than the laser or the light (which is activated depends on how long you press the "on" button). I'd prefer a separate switch for the laser/LED lamp.

The unit comes with a couple of power tips which I did not like much. Between the end of the cable, the power tip, and the connection to the battery, there is a fairly long, rigid chain of stuff ... It's very weak and very easy to snap one of the components (like the end off the power tip) if even slight pressure is applied. Anyway only
2 powertips are included (ipod and micro-USB) ... I prefer just to use the normal USB cable supplied with whatever device I'm charging. Note that on occasion when charging my Blackberry the unit produces a "Device can't charge
from this source" message. I find that some cables produce this message (even if the device charges fine from those same cables when attached to a computer or power cube) and that other cables are fine. I can't say what the source of this incompatibility might be (something to do with the way USB cables are wired?) but it can be annoying.

Great cables especially for the price, only issue is the micro usb end gets bent as most do, all 3 were unusable after 3 months.

You can see in the photo the hooks are mostly flush with the body of the connector.

After 3 months of use I have to find a replacement USB cable. I plug it into my tablet and it wants to fall out. Therefore it won't charge my tablet. The 10 foot length is nice but the micro connection just won't stay in to charge the device.

Anker customer service sent me a replacement after 3 months. This shows that they care about their customers and back up their product. I originally gave this 2 stars but after they sent a replacement I have upped it to 4 stars. I do like their products and I'm hoping the replacement lasts a long time.

Depending on your configuration, you may find that the direction in which you USB cable tip bends when forming a 90-degree bend can make a big difference in the reach and organization of cabling. This left angle cable definitely simplified my current set up for charging my phone; no longer do I need cables to cross or stick out awkwardly due to bending in the wrong direction!

None of the included tips fit my laptop. I'm not angry, though, since there a lot of tip styles out there for laptops these days (mine uses a custom 4.5x3.0mm size which also incorporates a "smart" center pin, for example). It would help, however, if seller stated exact tip sizes that are included. From what I noticed, most tips are common, generic sizes you'd find bundled with most converters you'd find at say Walmart or Radio Shack. As others have mentioned, not being able to switch the tip polarity is a nuisance, but it's hard to complain for the price I paid.

Make sure you use a volt meter to test output voltages on this device since mine were off to those stated to some degree. Thankfully, this converter incorporates a voltage regulator which makes the output voltage steady even if the input voltage varies slightly (I used inputs of 11Vdc then 13Vdc and found voltage outputs for each selector switch position to be within 0.1V of each other). Very good indeed.

I have not tested the claimed 80max output of this converter yet, but it seems to be able to charge the battery on my 15.6" laptop just fine, even when I'm on there using it.

usb end loose, works but could have better construction

Works great, but the Micro USB end of the supplied cable is a little flimsy, and I had to replace it after it stopped connecting properly.  Still a great product.

The TopG micro USB to USB Cable is a great replacement cable or just a useful extra one to charge you devices like a Galaxy S4. The cable is quality made and can last a long time if you take care of it. This cable is unique because when it is not charging or finished charging a device the micro USB tip lights up blue and when it is charging the device the micro USB tip lights up red. The micro USB tip does not work with all cases because it has an oversized micro USB end (-1 star). The cable is white and is 3.3ft in length. The cable is average thickness.
I recommend this micro USB cable. It simply works and it is unique!

I was supplied a sample for test and evaluation, for free to keep, and I promised that my review is fair and honest.

There are just 2 areas where cheap micro usb cables always fail.  One is that the micro usb connector starts to mate too loosely after little usage, and the other is that the sleeving behind the micro usb connector comes loose and end up with broken electrical connection.  I can tell those problems are covered on these Syncwire cables.

ANKER's ACHILLES HEEL: No markings on micro-USB connector!  I would have rated this cable 5 stars, but its design is so seriously flawed that it does not meet the USB standard.  The smaller micro USB connector does not have either the USB logo or the Anker logo on it, making it difficult to connect to either my Samsung tablet or Samsung Galaxy S7.  I have to turn on the light, go find my glasses to be sure I'm not forcing the micro connector in upside down because there are no markings on either side of that connector.  This might work fine on a symmetrical connector like the ones Apple uses, but its a royal PITA for an Android connector which is non-symmetrical.  Anker should fix this problen, as no other Android USB connector is blank like this one!

Good:

-Small
-Charges Ipod with 2 AA batteries
-You can buy other tips to charge other items or new ipods when they come out
-my understanding is that you can get wall and car chargers that work with the same variety of tips

Bad:
-seems like the plug that plugs into the tip could break easily. It hasn't broken, but I feel like I have to be very careful with it. I lay it carefully on a flat service and don't move it when I'm using it to charge. I don't put it in my pocket. I don't store it with the tip attached. I have to keep the tip and device in a ziplock bag since I'd lose the tip. Iit just makes it awkward.

I like it, but it would be amazing if there was a cover that was big enough to cover the end with the tip attached. The shape of a deoderant cover would work great since this has that oval shape. If there was something like that included, it would be a definate buy. It's still a definate buy if you need something for camping or whatever.

Great cable.  The insulator on the micro usb end is too thick, and needs to be shaved down for phone use.  Then it fits fine.

Poor wire to Micro USB connections. The great thing is some of the cords in the pack work well for a couple of uses, until like the balance of the cords in the pack, they have to be plugged in and placed into a secret position so that the device will charge. If you have mad puzzle solving skills and identify the ever-changing secret position, the cord will work again; unless you breath on it. I was happy to have 10 nice long charging cords on hand at a decent price under $20, but as with everything else you get what you pay for and sometimes less.

Bought this as a means to the end of constantly buying micro usb cables, but my search still continues. These cables initially seemed robust but I did not really like that it lacked flexibility for bending. Not to say they are not bendable, just not as much as I would have liked. The extra length was really nice but after 3 months the cable itself became intermittent and had to be angled or bent a certain way to maintain charging status. I was surprised considering all the good reviews. To be honest I don't completely hate this product, I just wish there was a little more to it. But for the price it isn't the biggest loss.

AUKEY has made a reliable, sturdy USB 3.0 to USB-C cable and sends 3 cables for a good price! Impressed!
It does support Qualcomm QC3.0, but sadly, one of the three cables refuses to work with quick charge - I don't really feel like returning the product over one of three cables.
As for the rigidity, I personally like the rigidity of the cables; the cables feel sturdier and don't flip and turn and get tangled up.
