I just got my first usb C phone (nexus 5x) and previously all of my cell phones have had a micro usb port. These adapters work great, they can both charge the phone as well as do file transfers. Buying these adapters has saved me a lot of money and hassle, instead of buying a bunch of new usb c cables (which are quite expensive) I can just re purpose my old micro usb cables.
Additionally, it helps to have only one set of usb cables, than can function as both micro usb, and usb c. So when friends come over and need to charge their phone, I don't have twice as many cables laying around the house. I just pop off the adapter and the same cable can be used for charging a different tablet or something else.

These adapters may not be the prettiest, but they're inexpensive and they work consistently. There are actually two places on the adapter to plug in your device, so if you're staying somewhere that doesn't have many plugs, you can double up. The two plug in spots make this my favorite adapter by far. I don't have to worry about the bulk of a power strip, and can charge two devices at once.

The adapter is working as stated.  It charges very rapidly, even when two phones are plugged in.  You will need an additional I phone cable to plug into the usb.  I have not  used it to charge any other device (kindle, i.e) but I have no doubt it will work as expected.  Would buy again.

When I first figured out my LG G2 needed a SlimPort HDMI adapter rather than the existing adapter I had from previous phones I was concerned about finding an adapter with quality build that consistently worked. I was pleased to find this adapter has worked great and has worked consistently without intermittent glitches.

No reason to remove a star, but it would be nice if the device had a splitter built in to allow both a standard HDMI cable as well as my phone to use the same cable without having to detach each time.

I've used these with the last few phones I've had, and they work great! Also, the price is nice :)

When looking for a dual USB adapter I found it difficult to find one that had two 2.1 amp ports.  This one does.  It is well constructed and works as advertized.  I recommend it for anyone who has two devices that require 2.1 amps that they want to charge at the same time.  Just be careful about your cables.  They have to support 2.1 amps as well.

Wors well - use it in my second car with an adapter and charges both my S3 and S4 quickly!

I bought this combo just for the AC and 12V-USB chargers. They both work rather well for any portable devices besides Samsung's.

Work extremely well!! I have a USB current-meter, and I've been measuring the amperage each phone/tablet I own has drawn from different sockets. When you use any Android or iPhone with a computer USB port, in media mode, the power output from the computer is about 0.45A, which makes for really slow charging. Now with these PortaPow adapters, I'm seeing 1.1A output from the computer!!! Now I don't need an extra wall adapter charger at my desk, because my computer charges the phones just as fast!!

As an added benefit, this adapter is small and removable, so when I do need to transfer files, I can just unplug it and use my phone as a storage device, and then when I want quicker charging, plug it back in!

I recently got a Nexus 5X and needed a converter for all my other chargers. The package came quickly, and I immediately tested both adapters. They worked perfectly. They're so tiny too! I plan to keep one in my purse/wallet for when I'm at other people's houses, and will probably leave one at my boyfriend's place. I would definitely recommend getting these. It's a good price for a good product.

Does the job and will charge two devices at the same time.

These adapters work very well. They fit on my other-branded premium cables nice and snug and allow me to continue using them since switching to a Type-C phone. I've tested these and they don't seem to degrade the charging rate at all. Overall very happy, I need to order another package.

The Chargers were great. I made a mistake in ordering them. I thought I was ordering the ones with the telephone adapters, I was mistaken. The company was kind enough to sent me the adapters but they failed to send the cables that attach to them. I thought it was very nice of them to send the adapters, free of charge, to me anyway. Thank you.

Great fast charging adapter.  My Samsung Galaxy S7 edge (too bad it only accommodates Quick Charge 2.0) charges quickly using this adapter, so it appears to work like it is supposed to thus far.  Hopefully, it holds up over time and continues to work as advertised so that any future phone purchases that support the 3.0 standard will charge even faster!

Very efficient dual port charger.  Both ports worked without issue and seemed to charge devices faster than the stock/OEM adapters do.  Multiple devices were charged (iPads, S3 and Gtabs) without any issues.

My charger that came with my phone died. So I decided to order these. The price is great, and you get 2. I absolutely love these chargers. They seem to charge faster than the original one that came with my phone. It's awesome. Also are a little longer which is great!!! Definatly recommend these chargers.

Works great and charges two Quick Charge 3.0 phones at the same time without a single problem (two Moto G5 Plus). Highly recommended!
