After using for 2 weeks, woke up to a USB cable smoldering on a sofa pillow. Yes it was probably the fault of the cable since it was smoldering at the end that gets the most bending, but it highlights the vague wording the maufacturer uses about safety. Notice that it doesn't call out automatic overheating or current shutdown, just vague reference to safety. The charger was hot when removed, but is still functional. No matter, I am returning and buying an Aukey which explictly calls out this condition for shutdown. And will start using a charging stand to keep cables confined. A very close call.

This is a great unit for charging, Normally when we travel we have 2 note 4's and my Galaxy Tab Pro 12.2 to recharge every night. Since I come to bed later than my wife I use the Quick Charge port and her phone and My tablet will get the two voltIQ ports. So I decided to test that scenario out and here is what I've observed:

For the Note 4 on the QC 2.0 port It charges at 8.94V @ 1.62A for a total of 14.5w with the screen off which is close to the 9.0V that the OEM charger outputs.

For the Note 4 on the Volt IQ port it charges at 5.1V @ 1.67A for 8.5W which appears to be the limit when not using a Quick charger

For the Galaxy Tab Pro 12.2 on the Volt IQ Port it charges at 5.1V @ 1.7A For a total of 8.7W which is as good as the Samsung OEM charger.

So the total wattage of my setup is 14.5+8.5+8.7 or 31.7W which is well under the 42W maximum. The unit did get warm but not overly hot.
I Also learned something about the Volt IQ ports, If you use an OEM cable they will charge at a maximum of 1A, This limitation is not present for the Qc2.0 port, However I had also purchased some Tronsmart Cables with this charger and when using them I was able to achieve the 1.7A on the Volt IQ ports.

All of the voltages and amperages were read with a Portapow premium USB monitor.

Mine had a problem with the fold up plug but customer service quickly replaced it for me and the new one is working great!

Edit : Tonight our daughter in law came over with her Ipad in need of a charge so I hooked it up and noticed something interesting, The QC port charged at 0.5A This may be due to the cable which we stole from an ipod, or the fact it was an Ipad 2 and not a new Ipad but when plugged into the VOLTIQ ports it charged at a full 5v 2.1A

The device works great for most everything. I have had no problems at all with the 2 regular ports. I thought the quick charge port was working fine with my Galaxy Note 4 since it was detecting it as a quick charger and charging my phone just as well as my OEM charger.

Over a period of 2 months or so, my phone battery started freaking out. For example, my phone would suddenly turn off even with a 50% charge. When I pop in the charger, it says it's charging from 0%. I pop out the battery and re-insert, and the battery says 50% again. I thought it was the battery, but when I started charging again with my OEM charger, I was able to get it stabilized but... it wouldn't charge past 90% no matter what. Thankfully my phone was still under warranty, so I got a replacement battery. I will not be using this charger to charge my Note 4.

UPDATE (9/17/2015)
*************************
While I stopped using the charger to charge my Note 4, I continued to use it for other devices. Last night, I noticed that it started making a high-pitched, faint but audible whining sound. I unplugged and replugged, and the sound continued. Left it unplugged overnight and tried plugging it back in this morning, and no sound. Not sure what's going on, but now I'm a bit wary of using the device at all.

+Great build quality
+Compact and sleek design with non-intrusive LED
+Foldable plug for easy stow
+QuickCharge 2.0 port for very quick charging
+Smart ports for Apple compatibility

-QC port is not smart enough to detect Apple devices and only does 1A when I connect iPad Mini2 (just use the Smart port!)
-USB ports are upside down (now I'm nitpicking)

This is a very handy charger with excellent build quality. It has just the right number of ports for travel or even everyday use in a very compact size. The folding plug design is very nice and minimizes bulkiness making it easy to carry around or stow away. There's a very small nonintrusive LED indicator on the charger to show whether it's powered on or not.

I tested this charger with a Galaxy S6 and an iPad Mini2 and I'm happy to report it works as advertised. Here's more detail on the tests I've done.

Galaxy S6: QuickCharge port is almost 3 times faster than using the Smart port and charged 15% in 10 minutes.
1. QC port: 9.0V 1.8A, 16.2W
2. Smart port: 5.15V 1.05A, 5.4W
3. My other 5V 2A charger will do about 5V 1.6A, 8W. I saw it charges about 10% in 10 minutes.

iPad Mini2: Use the Smart port and get same OEM charger speed.
1. QC port: 5.12V 0.95A, 4.8W
2. Smart port: 5.1V 1.99A, 10.2W
3. Apple OEM charge also does 2A, same as the Smart port.

When charging devices that support QC make sure you use a data cable. Any good quality data cable will do. QC uses those data pins/wires to communicate between the supported device and the charger. If your device supports QC, the charger will raise the voltage to 9V to provide more power. If you use a charge-only cable, it'll do a regular 5V charging.
