Customer Reviews:* With all of the various family portable electronic devices (2 Kindle Fires, 2 iPhones, 2 iTouch, Crackberrys, iPods, iPad 4, etc) I needed to have a charger that could handle all the power requirements. This charger did it! ALL the devices are charged from this charger including the iPad 4s. Then when I bought a battery pack EasyAcc 4 x USB Output Port 12000mAh External battery pack (http://www.amazon.com/gp/product/B008YRG5JQ/ref=oh_details_o06_s00_i00?ie=UTF8&psc=1) it charged it perfectly. Best price and best charger to replace all those OEM chargers at a fraction of the price and more power so they charger faster. Without a doubt this is the one of the top five accessories I have purchased for electronics. You cannot go wrong! I now have 3 of them. All work as promised.* I tested PowerGen Dual Port 15W / 3.1A USB Wall Charger with Nexus 7 Tablet, Samsung Galaxy 7.7 Tablet, and Samsung Galaxy Nexus cell phone, and SanDisk Sansa Clip+ player.I received PowerGen wall charger for testing from the manufacturer to write an honest and unbiased review and you will find both pluses and minuses of my experience in this review.Note that some early versions of this plug had quality control issues. My plugs did not have any issues, but some of the early testers reported problems. PowerGen notified all testers and made the plugs unavailable until the problem has been resolved. I received a notification that the problem has been resolved, and the new stock does not have the issue. Symptoms of the problem: Due to a poor connection inside the plug, the status light goes on when the plug is plugged in, but then goes out a few seconds later.I am attaching two collages with 8 photos (each collage has 4) labelled with numbers 1-1 through 1-4 and 2-1 through 2-4 under customer photos that I will be referencing in this review.The first thing I noticed that the charger has re-tractable prongs which is very handy for travel. Photo #1-1 shows the black plug with prongs retracted, and the white plug with progs extended.Photos #1-3 and #1-4 show this plug on a power strip. This is where the only negative thing I have to say about this plug comes in. The position of the prongs is such that this plug takes up two slots and a bit of third slot. As you see not only does each plug cover two outlets, I also could put two of these plugs next to each even on the short side. The prongs are not polarized as you can see on photo #1-1. The plug itself is very slim, if the prongs could have been oriented differently, the plug would only take 1 slot.The plug has two ports labelled "A" and "NA" which stands for Apple and Non-Apple devices (see photo 1-2). I own all Android devices but I tested both ports to see their behavior with my devices. The charger comes without a USB cord, so tested it with the USB cords that came with my devices.I used Battery App by Elvison to determine how each device recognized the charging source. 'AC' status means the charging is at full charging rate. 'USB' status indicates charging at a lower charging rate. 'Discharging' status means that the charging rate is below the power that the device is consuming so it slows down the discharge rate but does not re-charge.The key findings:(1) Excellent results on both ports for Nexus Phone and Nexus 7 Tablet(2) Samsung Galaxy 7.7 can be charged on NA portThe table below summarizes my findings:Nexus 7 Tablet (photo #2-2, note the port is labeled "A" is closer to the edge of the plug and the port labeled "NA" is the one that is further away from the edge of the plug)(Shown in Photo 2-2)--------------A port -- ACNA port -- ACSamsung Galaxy Nexus Phone(Shown in Photo 2-1)--------------------------A port -- ACNA port -- ACSamsung Galaxy Tablet 7.7(Shown in Photos 2-3 and 2-4)--------------------------A port -- discharging when screen is on, charged slowly with screen offNA port -- ACSanDisk Sansa Clip+ MP3 Player------------------------------A port -- charged at AC rateNA port -- charged at AC rateCharging times for Samsung Galaxy Tablet 7.7-------------------------------------------------NA: from 90% to 100% ---> 33 minutesA: from 90% to 100% -> 1h 37 min charged when screen was off despite saying discharging (powering the screen was enough to turn from slow charge to discharge)Samsung plug that came with the 7.7 Tablet: from 90% to 100% ---> 1 hourCharging times for Nexus Tablet-------------------------------------------------NA: from 94% to 99% ---> 17 minutesA: from 94% to99% ---> 19 minutesThe behavior of both Nexus 7 and Galaxy Nexus plugged in at the same time was the same as when they were plugged in individually. This means if you can charge them both together at the same time. If you need to charge Samsung Galaxy tablet and one of the Nexus devices you would need to put the Galaxy tab on the NA port.The MP3 player worked in both ports. I was able to charge and listen to the MP3 player at the same time.To summarize:I liked:---------1. Excellent behavior on both ports even when you have two Android devices2. Samsung tablet 7.7 charged twice as fast as with the plug that it came with2. Solution for MP3 player with built-in battery3. Can charge two Android devices at once at AC rateI did not like:--------------1. Position of the prongs that makes the plug take 2+ slots on the stripI compared this plug to PowerGen Dual Port USB 2.1A 10W AC. And before I upgraded my Nexus devices to JellyBean 4.21 this plug gave a better performance on A port. However, when I recently retested 10W plug with Android's Jelly Bean 4.21 the difference became less significant. Nexus 7 shows the same behavior on both plug (both ports charge at AC rate), Samsung Galaxy Nexus Phone still does better with this plug on A port (AC rate vs USB rate).Here is a link to my review of 10W plug if you are interested in seeing the details - http://www.amazon.com/review/R1WWWT839MIV8E/ref=cm_srch_res_rtr_alt_8Overall, This plug has given me the best performance of any dual plug I have tried. I recommend it.Ali Julia review
