The chargers with the attached cord are a lot better.  I only have a long cord and this is really a pain to use.

I have this as well as the bigger box version; this is a better design. One thing to note is that this charger has the plug prongs attached to the unit itself - its intended to plug the unit into a wall plug  and then run a long cable to the battery. If you have an outlet high on the wall near your car this is great. But if your outlet is far away or near the the floor you will have a hard time seeing the battery charge condition lights on the unit.

Excellent charger!  Way better than the Verizon charger.  With the Verizon charger, the mini USB end kept falling out of the phone, and the part connected to the lighter didn't always connect.  The Anker charger is smaller and fits more snugly.

I like the additional length this provides.  However, the factory charge cable has a lower gauge wire (thicker), so this takes much longer to charge the phone.

If you only care about the longer tether this is great.  If you want faster charge speed this is not for you.

The amperage and charging times for this item can hardly be compared. It powers newer devices that have large batteries and large screens that tax many chargers available today(LG G3 and Samsung Galaxy S5). Where it all falls apart for this charger is that it likes stop charging at a fraction of an inch pulled back and it likes to be pulled out way to easily with the slightest of disturbances which at times include driving over bumps. If you are vigilant and continue to check that it is indeed still charging then this is the charger for you.

These are great quality, but it is annoying that they don't use a universal cord charger (mini USB)--that fits for my cell phone and nook and small headphone and basically everything else I own that isn't an Apple product. I'm going to return them and get the more expensive model so I don't have to carry an extra cord when I travel. I read this on the reviews and thought it wouldn't be an issue. It is. Consider carefully before deciding not to spend the extra money for the more expensive model.

It's true that the charger cord is a much better length than the one that came with my Asus transformer T100 (compare 6 feet to about 2), and the cord itself is thicker and sturdier.  The charger has a light indicator (turns red when power is going through it) which is helpful and also a big improvement from the original charger.  However, the plugin port that goes into the computer is flimsy and cheap.  Since it was shipped to me without any apparent box or packaging damage this is definitely a manufacturing issue.  The plugin is already bent at an angle without any abuse to it and I feel like it's going to fall out in a month.  If you're like me and you gave up on the original charger that came with your Asus and you're here looking for a bigger and better charger, this one is good enough as an emergency replacement, but be careful how much you pay for it.

My Samsung Charger had the end corroded from moisture and would no longer charge. I like the detachable cord to use with both the charger and computer. U-9 cord is necessary for the Samsung to charge correctly, you can find cheaper cords but if its not Samsung it likely doesn't work.

Bought this so I could be on my phone while charging it in bed. It worked, but the cord was so long that it took so long to charge my phone (like 4 or 5 hours for iPhone 4s). Finally bought a 6 foot charger and it works so much better.

I have to agree with the other reviewers; the large, long cord attached to this charger reduces it's usefulness for travel considerably. Sony design people, we're not charging nuclear missile batteries here!  Perhaps you should look at the battery chargers Canon provides for their point and shoot cameras, a compact body and no cord at all, just plug blades that swing out.

the single chargers seem to be more reliable than the dual chargers, always seem to have one side of a dual go out

This charger only works on my phone if I have my phone sitting in a certain position. I do like the extra long cord, even though it doesn't do me much good since my phone only charges like 10% of the time.

It is great if you do not want to connect your charging cord. the device is 1/4" longer and you can not attach the AC cord to PRO.

The charger is much lighter weight than the one original that came with the Chromebook. The cord is longer so I don't have to sit so close to the plug to charge it. It is great.

I like the idea instead of usb cord for the charger. It has a dedicated cord for the charger!

I tried to first install it inside the case of my phone. But LG built the phone I am using with no extra room in the case.
So I was forced to secure it to the outside with some electric tape that allowed some extra play in the short cord. But now I can unplug it to use the faster hard wire charger when I'm near an outlet. It does occasionally get caught on clothing. I did deform the plug at some point shorty after I received it but it still works. Barely keeps it charging when I am using apps such as UBER or just music.
Overall I would recommend this item if your not afraid of a little Do It Yourself engineering and this won't be your primary method of charging your device with the standard mini charge port.

These chargers hold the charge just fine. The problem I've had is that after a while, the point where they attach to the Kindle becomes loose and the cable falls out easily.  Many times I have picked up my Kindle thinking it was fully charged to see the cable had pulled out some and it was drained. In all fairness, I do keep it plugged in all the time and that may account for the wear and tear. If I put some pressure on the end it will tighten up for a while but in the end  I have had to return several of these after about 3 months. No problem getting a  free replacement though. For that reason I keep a spare on hand.  I do like the extra long cord and before it comes loose it works perfectly.
