Quick Charge 2.0 Certified 30 Watt USB Charger

I've purchased multiple quick chargers and just got this one. I have the tenergy, aukey, anker, and the original samsung to compare. It appears the Note 4 does not benefit from the higher voltages (20v) for quick charging as the charge time seems similar among all of the chargers, however, if I buy a tablet in the future with quick charge or if samsung enables it for any of it's existing tablets I will be thankful and ready with this charger. The size of this charger is larger than all of my other QC 2.0 chargers. it is larger in all dimensions but the plugs will fold in making it easier to pack as a square than the other chargers that have the prongs sticking out. I do not notice any coil whine on mine, and have it plugged in at my work desk all day next to me. The charger comes with a premium usb cable capable of handling the higher current levels. Others (tenergy, aukey, anker) do not. so this is a nice addition. for the price, currently $19.99, it is cheaper to get this charger with the usb cable, than to buy any of the others and an additional cable capable of the higher current. I only buy products that I can confirm are Qualcomm QC 2.0 qualified and this is on their list.

Great charger, works fast and efficiently. I bought this to replace my stock Motorola Nexus 6 charger which had been stolen. It works beautifully with both my N6 and my NVIDIA Shield Tablet. Charges in about an hour, though a lot longer if you're using the device while on the charger (like I do with my tablet). My only problem with this charger is the USB cable. It's a good 20-gauge thickness, so it handles the 30 watts well. However, the cable is SHORT. It's like two feet long. Most USB cables that come packaged with chargers are at least three feet. My N6 stock USB cable was LONG, if I remember it was four feet long. And in my experience, this cable has trouble staying plugged in. It's loose. Sometimes I somehow manage to unplug it even when I'm not using the phone/tablet. One morning I woke up to find my phone dead, with the cable partially plugged in. Fantastic. Not very reliable, is it?

This is a good quality Qualcomm Quick Charge 2.0 compatible charger for the money. When used with my Droid Turbo, the phone correctly identifies the charger as a Turbo charger (i.e. "Turbo charger detected"). However, I do not believe the build quality is as good as the original Motorola turbo charger. When I test this charger against the two Motorola chargers I have, this charger only provides 14W versus the 15W provided by the Motorola chargers. For my fellow engineers out there, the Motorola chargers consume 240mA at a Power Factor of 0.52. This charger consumes 280mA at a Power Factor of 0.42. I do not have the necessary test equipment to test the output of the chargers, but they obviously cannot output more power than they draw from the receptacle. The lower Power Factor of this charger suggests that the quality of the internal windings may not be as good as the Motorola units. That being said, at less than 60% of the cost of the Motorola charger, I don't think anyone could complain.

I have had this product for almost 1 year ( a little bit over 10 months) i used it as my primary charger for my samsung S6 and it worked phenomenally!! it charges fast and had almost no problems. The unit it self is nicely weighted,but the plastic feel kinda cheap and the usb port housing itself lost its grip onto the cable.**the reason for the 3 stars** the unit randomly stopped working today ( feb 12,2016) which is supposedly under the warranty,but after searching for a way to return the charging unit, for over a half an hour with links that redirected to other links; ultimately i will be purchasing a new charger and from a different company.

after 3 months with this charger I can say that it definitely charges faster than a stock samsung charger however the usb cable that it comes with is terribly flimsy and always slips out of my phone, sometimes I'll walk away thinking that my phone is charging only to find out that the cable came loose and have to wait even longer. I have a note 5 so I know that its definitely not an issue with my phone as other chargers fit perfectly fine. If the cable were changed for this item it would be a perfect product. Until then, 3 stars.

Very fast Quick Charge 2.0/Adaptive Charger, the whine that people associate with it is real but it went away after a few days of use in my case. Definitely worth the price, just pair it with a good quality microusb cable and you will be amazed of the results.

Works perfectly with my droid turbo and sony z2 tablet. But the usb socket is loose no matter what cable is used with it.

Have had with no issues for about a year now, great product, charges faster than any other charging block I've seen, great for all devices including larger Li-Ion batteries
