Was having problems recharging my Kindle Fire. The Amazon Kindle 9W PowerFast Adapter solved the problem.  I wish I had known about the PowerFast recharger when I purchased the Kindle.

This device is very helpful if you do not have the time for your Kindle Fire to charge overnight.  It mates with the charging cord without problem

Just received and installed today.  Installation was easy with one gold and one silver terminal and a ground terminal.  The overall size of the unit was not much larger than a standard duplex receptacle and fit easily in a standard size j-box, which is nice.

This is an ideal solution for an outlet at the end of our kitchen counter where my wife and I charge out gadgets.  At any point in time we are charging one or more of the following:  iphone 4s (hers), Windows Phone (mine), ipad 2 (hers), Kindle Fire HD (7") (mine).  The USB ports charge any of these devices, regardless of whether or not the device is powered on or off.  When plugged in, I can see the on screen battery indicator showing that each device is actively charging when connected via the USB port.

Results are mixed when trying to charge two devices at the same time using both usb ports.  I've found that the Kindle Fire HD will not charge when any of the other devices are charging on the other port.  Same result if the Fire is powered on or off while charging.  The fire charges fine on the USB port when no other device is charging at the same time.  Ipad and both phones charge fine with other devices charging on the other port.  Not sure if this is just a Kindle Fire limitation.  This seemed to be the only problematic device.

Charging times are definitely slower than using a standard outlet with the factory provided usb-to-duplex converter.  This is fine for an overnight charge, but better to use the duplex outlet on bottom with the factory-provided receptacle for a quicker charge.

Altogether not disappointed, but not thrilled.  Would love to see these "USB outlets" evolve to a point where you don't have to think about what you can/cannot charge in tandem.  I like that these are now available and will keep an eye on reviews for new models that solve some of these annoyances. I'll update this review if my perspective changes following more use.

Before they sent me this new charger, my Kindle could be plugged in all night and still wouldn't have a full charge. I thought there was something wrong with my Kindle but now it works perfectly.....Thank you

At the moment, I love it!

It's black, the color I ordered. It was partially charged so I could play with it right off.

My Kindle Fire HD that I bought January 20, 2014 won't charge even when plugged in. At least 1 reviewer had this problem with this product. I'll post an updated reviews.

I've downloaded some apps, including Kindle.

Plus I get a free protective case for writing. Though I might get something else.

This charger works really well with my Kindle Fire.  I was having issues with the prior charger and not always having a charging connection but this charge and sync dock cradle to care of that issue.

This was a lifesaver for me! The charging port on my Samsung Galaxy Note 4 broke and could no longer charge the battery with a normal usb charging cord. I immediately went into a panic looking for other options and tried not to think about all those pictures I could lose. I had gone to Best Buy hoping they would be the solution to my problem and unfortunately they were not! Basically my phone was already obsolete. I then went to my local mall hoping I'd find something at the kiosks that could help me. One guy had a universal battery charger which was able to charge my battery. Downside was I had to take the battery out of my phone and the charger wasn't strong at all. I'd leave the battery in the charger over night and only have 50% of battery life.

Needing to find a better solution, I came across Digiyes Ultra Thin and Light Weight Wireless Charger Charging Receiver Module for Samsung Galaxy Note 4 with Integrated NFC Coil. In order for this to work I needed a wireless charging pad. I came across the Samsung EP-PG920IBUGUS Wireless Charging Pad and placed the order which I had delivered in 2 days.

Installation, if you can call it that, was simple enough. Plug the usb cord into the charging port and plug the adapter into a wall outlet. Once I placed my phone with the Digiyes Ultra Thin and Light Weight Wireless Charger Charging Receiver Module for Samsung Galaxy Note 4 with Integrated NFC Coil on top, nothing happened. It took some fiddling but eventually I was able to line up my phone with the wireless charging pad and saw the blue light appear on the pad and my phone started charging!

Making sure that the charging pad and the receiver module are lined up can be a bit challenging but it only takes a few adjustments and eventually my phone will charge. I have been using the charging pad for a few days now and it's been working great. I do keep the usb cord connected to the charging pad because after what happened with my phone, I don't want to take the chance of breaking the pad's charging port.

I also like that the charging pad is fairly big compared to a charging cord. There's less chance of losing or forgetting the charging pad as it is with a cord and hopefully it won't break as easily as a cord can. I'm happy with my purchase and hope it will last for some time.

I puchased this as an easier way to recharge all my electronic devices. I had gone through a number of chargers for my phone and kindle some of them lasting only a couple weeks. I now use this and I am able to charge my phone and my kindle in a couple hours. The only thing I don't like is the bright blue power light on top. It does not warrnat a lower rating though.

Great! My kindle would no longer charge so Amazon sent me this adapter. My kindle fire now charges but not faster than it did before. I'm not that big on technology but this charger worked for me. Thank you Amazon!!!

I absolutely love this PowerFast Adapter and I am so happy I purchased it. Before I just used the regular charging adapter that came with my kindle, and many times I would find myself running low on my charge and having to wait several hours before I could use my kindle again due to the length of time it took to charge. Since purchasing this I find that it only takes about one hour of charging and I am ready to go again.
This product is for anyone who hates to wait to long to get back to their kindle.
My spouse uses this now too, so I am thinking about purchasing another one just for him to use when he travels.
I give this five plus stars.

For months I had had problems charging my kindle and it got to the point where the only way my kindle would routinely charge was if I plugged it in to the USB on my computer and then it took 8 hours or more. With this new accelerated charger, the second I plug it in, the orange light comes on, the icon is displayed and the kindle actually says "charging "on the screen. My kindle is charged and ready to go in less than two hours. I do a lot of reading and now I find I have access to my kindle whenever I want to use it compared to before when it would sometimes be charging when I wanted to read.  This is an excellent device and it works  perfectly. It gives me more reading time and actually allows my kindle to be charged quickly and easily . I am so happy with it.

Excellent! My Lumia 1020 charges super fast, so does the Kindle. iPad2 is currently plugged into it while my son plays, it's already charged up his kindle and topped off my phone today and is still at  two lights out of four. I can even plug my phone into it and plug it into the wall charger and have both end up charged--this is convenient when I need both charged but only have one wall adapter handy. This is has totally changed how I use my phone, as the battery when full will give me about 24 hours of charge if the phone starts out charged. Even when I'm doing heavy use, the phone will still actively charge while plugged into the battery pack.

I've had this for more than a month, and it's still going strong. It's actually a faster charge than the wall charger that came with the phone. I have no trouble charging the Kindle Fire HD right next to the Lumia, though that is a little slower.

I was hesitant to purchase but am so glad that I did.  Between my iPhone, kindle, iPad & my husbands iPhone, & ipad this has been great for recharging when multiple items need recharging at the same time.  Was also very convenient on a 10 car trip which allowed me to recharge my kindle and iPhone making them useful the entire trip.

I need to recharge my Kindle Fire HD every day since I read a lot and also enjoy watching movies and TV shows on the Kindle.  The fast charger will recharge the Kindle from 12% to 100% full charge in about 3 hours.  For me, this is a worthwhile item.

I love the Powerbolt Duo USB Charger. Finally we have a dual USB charger so that I can charge my Kindle Fire HD 8.9" and a cell phone from the same 12 Volt power outlet in my car. Before, I would have had to change out my charger or charge my Kindle for a very long time. A wonderful device.

I am really impressed with this device, although I  haven't had it for a long time.  It was easy to charge, held a full charge for at least a week before I had occasion to use it, and only used 19% of the full charge to get my Kindle back up to speed.  If it holds up over time, it will be a very valuable backup device to have on hand, particularly in case of power failures.
