It works exactly as advertised, and can charge an iPad Air from either port, while charging an iPhone from the other.  (I don't have two iPad Air, so I can't verify that it will charge more than one at a time.)

exactly as advertised. Nyko's products are very good, I bought a plug and play charge kit from them a good while back, and it still works like a charm. however, there are some kinks about a cord that twists and turns everywhere on my crowded spaces that make charging sometimes a hassle. so to replace it, and to find a better alternative than a plug and play, i bought this. and it works like a charm, the batteries charge very good, last for hours on end of hard game time, though not forever. they do recharge giving them much more life than standard batteries that deplete, or other solutions such as rechargable AA batteries that hardly last. as a budget option compared to higher named brand and rather expensive battery solutions, this charge base, with it's 2 battery packs, is a very good solution for anyone with an xbox 360 controller. not many of us still use such, but doesn't mean they are useless or gone.

It does exactly what it promises, and works wonderfully.

This power bank is exactly what it claims to be. It will charge my Iphone 7Plus four times, and it is amazingly fast, too. The only negatives are that it's somewhat big and a little heavy, but it's not so much that I don't take it with me every day.

Thus far has worked flawlessly.  Provides a full charge on my iPhone 4s.  One quibble is that the phone can get hot if I use it while it's charging, but that's just the laws of physics and probably a user error.  This is intended for use in a pinch, where no other power sources are available, and it does that job well.  I haven't left it unused for more than a week, but so far it seems to hold a charge while idle well.

It's solidly constructed, and fairly attractive.  When the battery goes, or if I feel I need 2 backup charges, I'll get another of these.

Worked exactly as advertised on a trip to Paris and London while charging for devices at a time. Also, it's working perfectly at home in the U.S.A., too.

As advertised.  Works exactly like it is supposed to work

Works exactly as explained. It does take a little longer to charge, and once fully charged it shuts off. It's very handy to lay my phone down on the charging pad to charge when it's not in use.

This adapter worked exactly as stated and allowed us to charge the camera battery, phone, ipod and even heat up a flatiron (which I wasn't expecting).

Pros:
  -Performs exactly as advertised.
  -Charged five devices quickly and effectively (work phone, personal phone, work iPad, personal iPad, headset).
  -Small footprint, and
  -NO MORE SEARCHING FOR OUTLETS IN MY HOTEL ROOMS! Thank you!

Cons: Just one, and if you're prepared this isn't even a con.
  -If you're buying to use for travel charging, so you don't have to unplug everything when you leave home, just understand that it does not come with the USB cables. I had plenty, so not a big deal for me, and that is clear in the item page.

So far, thoroughly happy with it!

It does exactly what it is supposed to do. It charged my devices without any difficulties (Garmin 800, iPad, shuffle, bike lights).  The only drawback is that it does not include AC charging capabilities for the portable charger itself.  It has to be charged through a USB device.  You will need to have your own power connectors for your specific devices.

This product is great. It works exactly as advertised. I love how long you can go in between charges. It seems to last forever! And the quick release tab makes charging extremely simple

Does exactly what it should.  Charge several items at once and increase your computers USB capacity.  I have had no issues with it.  It looks good and works well.
