They even seem them at the Warehouse although for around $80.
With no mention of smart charging capabilities to auto detect the type of device that product may be no more useful than a $2 shop charger. It looks quite simply like a device simply putting out voltage on a USB port, which is IMHO pretty much useless these days
The most important aspect of a charger these days isn't the power output, it's whether it can detect the type of device and charge at full speed. This reason alone is my most USB ports in planes, airport lounges, hotels and cars within the past couple of years are effectively useless - even if they output 2.1A, they won't necessarily charge a modern device at any more than 450mA unless you supply your own fast charge adapter dongle.
I don't want to sound like an Anker fanboi, but the simply reality is right now their products are the best you can buy. Period. Nothing else on the market comes clone. No matter what device you plug in you get brilliant charge rates at a price far less than most of the competition.
That's not to say they don't have competition, and there are a few replica Anker chargers starting to appear on Amazon and I'm sure it won't be long before others have caught up. I'm not sure what Anker can then do to innovate - but they do have a fantastic name for themselves.
I'm in the US at present and have a big box of Anker stuff for myself and a few other people in the other Anker thread who contacted me when I offered to bring stuff back.
