Question: Will this charge a Samsung Note 4?
Document: I have a Samsung Galaxy Note 2. I had many universal chargers that I tried in the car while commuting and running GPS and my music. I would have been better off not even trying to charge the phone. The 2.4 Amp PowerGen made all the difference in the world. This thing charges up my phone faster in the car than the factory charger at home.
This is my replacement for iFlash Dual USB Car Lighter Charger Adapter with 3A Output (fast) Heavy Duty Ouput Support iPad 1 / 2 / 3, iPhone 5 / 4S / 4, Google Android Phones, HTC EVO, LG, Samsung Galaxy S II III Note, BlackBerry Moblie Phones, that died after just few days. So far so good.
I ordered this charger for my wife for her Samsung Galaxy Note 10.1. We can both charge our devices with this compact charger.
This charges my Samsung Galaxy Note 2 faster than any other charger I've tried! It's also very convenient to be able to charge 2 phones at once.
This charger works great for me. I can charge my Samsung Note and the companies iphone at once. One output is dedicated for the iphone. Would recomend, the price was right.
We used this charger in our car for our Samsung Galaxy Note 2 phones, and it charges very quickly. Make sure you use the white Samsung charger - it seems to charge faster that way.
This unit works well to charge my Samsung Galaxy Note, Blackberry 9780 or Iphone 4S. The iphone only charges in the port marked "A" while the other phones charge in either port.
This charger does what it advertises. I use it to charge a Samsung Note II. Just make sure that you buy a cable that can charge your device at the correct rate if you are not going to use the cable that came with your device.
Charges my Samsung Galaxy Note II. I have several old high amp charges buy my Note II refused to charge on them even though the charge symbol came up. This one works well.
I bought this because my girlfriend's Samsung Galaxy Note took forever to charge with my old car charger; it would actually lose power if she was using it while plugged in! This one gives a much stronger charge and seems solidly constructed too.
Answer: yes, it will charge a samsung note 4, but do you plan on charging anything else. Just because it is dual, doesn't mean you can charge to like things.  You can charge an Apple product and say your note 4, but not 2 samsung devices.
