Reviews say [amazon.com]
the 15w 3A device is actually 10W 2A, so I'll pass. Already have one of those. 2A is sufficient for one attached device. The problem comes when you try to charge two things at once, one of them doesn't get enough current.
New Trent website definitely says 15W/3A, so I wonder if the reviewer read on the box that one USB was 10W and didn't read any further (that it's 15W total)......?
I mean, if it really arrives as 10W total, then I'm hoping Amazon will tell us to just keep them, after they refund our money, rather than have us send them back on their dime.
