Duracell Powermat 24-Hour Power System for iPhone 4/4s - White

Works great with my Samsung Galaxy S6, and you can't complain about the price - I paid about $10.There are two wireless charging standards - Powermat, and Qi. Most cellphones only support Qi, and won't work with this charger, but the S6 supports both standards. This charges it just fine, and I assume charges an iPhone 4 just fine if you use the included case that I threw away. It's really nice that this is a two-place charger - just like the picture shows, you can put the backup battery and your phone on the charger at the same time and have them both charge.The backup battery is pretty slick - has both Apple 30-pin and micro-usb connectors that tuck in very nicely. The capacity (1850 mah) is smaller than my S6, but should be capable of giving it about a half-charge.With a Spigen Air Cushion case, the phone will charge but placement of the phone on the charger becomes critical. With the case, it takes a few seconds to get everything lined up so that charging will occur. Without the case, you can pretty much toss the phone at the charger and have it charge.All in all, this is a very well built setup, meant to sell for the $100 original cost, but is an absolute bargain for anyone who can use it at the clearance price.

Awesome little product. I bought this for a pma ready Kyocera phone. The extra battery, the 2 item charging pad, and the iPhone case i can re-sell to make my money back made it worth getting this compared to just a regular powermat. For those who have been asking, no you do not have to have an iPhone to use this. You just either need a pma enabled device with a built in antenna, or the pma case for your specific phone. This does not work with Qi enabled devices. Like usual with Amazon, it showed up on time. Product works great. The spare battery is awesome. Can charge it and throw it in your car or where ever until you need it. The charging pad itself is rather nice. Has a tone to let you know if you have the phone in the right place or not, also has a couple lights. The bottom has 2 semi-sticky strips so it doesn't slide around on you. Over all great product. Well worth the price and then some.

I've had this for about a day now, and overall it's a good device. Here's my first impressions:PROS:1. Aesthetically pleasing and overall good design. Some comments talk about how slippery the case is, but I don't see it as a problem.2. It charges the phone in about the same time as the original Apple charger.3. Pretty compact hardware, and the case is not bulky.4. The backup battery will be great for keeping in the car for emergency power. It will fit fine in the glove box.5. Convenience.CONS:1. Instead of the USB port on the case, Duracell should have built in the original style connector. If for some reason, the user doesn't have either the mat or the USB cable, they have to take the phone out of the case to charge it. Also, having the original style connector would have streamlined the case quite a bit.2. The "lid" on the case doesn't quite close all the way. I can see a bit of an angle between the lid and rest of the case. In other words, not the perfect fit. It's not bad by any means, but it's noticeable.3. The charging LED's on the mat, for some reason, are on the bottom of the mat, so they're hard to see in daylight. Why Duracell didn't put the LED's on the side of the mat (and there's ample room) is beyond me. Not good placement.4. You have to find the sweet spot for charging to begin. Not a big deal, just an observation.For the price, it's a keeper. Amazon sells the same thing along with an additional "bonus" single mat for $99 with retail packaging. Not worth it because obviously you're paying quite a bit for fancy packaging. I may buy another at the ~ $22 price.

I bought this item mainly to charge my Samsung galaxy S6 - which has the wireless charging technology already built-in. Given that the Samsung charger alone costs 2-3 times more, this is an excellent deal. Plus I get the additional ability to charge my old iPhone, and a portable charging battery as well. While the portable battery is minimal in features (5v, 1A, 1.85Ah), it is light-weight and will charge my Samsung to about 75%.The wireless charging is a great feature as well. No more fiddling with wires, etc. The iPhone case is well built and does its job well in both charging and protecting the phone without being too hefty.

I own a Cricket-branded Samsung Galaxy S6. The phone has a PMA receiver on it and so it charge with this charging station without any add-on cases, etc. However, it will NOT work through a case thicker than 2 sheets of paper. I have a Caseology slim TPU case (the Daybreak Series) and the charger does NOT work through this TPU case ... so basically only a naked S6 will charge!Using the Ampere app, I see that it charges the phone at about 380mA. While slow compared with a Quickcharge 2.0 charger and compatible cable, which usually clocks in at ~1100mA.It is a very sleek looking charger. The battery backup is pretty cool, though it is more gimmicky than anything, given the 1850 mAh capacity. Some lipstick charging sticks hold twice as much. However, it is pretty cool to be able to charge something else wireless next to my phone.Would I get this again? Probably not. Taking the case off my phone to charge it defeats the purpose of "ease" ... which was what I was going for with getting a wireless desktop charger. It takes just as much effort (maybe less) to plug a quick charge micro USB cable into the base of the phone. Wireless charging won't mess up the micro USB port, though ... so there's that.I'll see how long I keep this on my desk. For less than ten bucks, it was a fun splurge.
