Can this charge the Microsoft Surface Pro twice? If not, at least 1.5x? From Qi-Infinity's website, it shows 2x for the Surface.

For Surface RT, it will do more than 2x. For Surface Pro more than 1.5x. Here is the math -&gt; You need to calculate with Watt-Hour and not with mAh. Surface Pro has 5,676 mAh capacity and it operates at 12V, so the total Watt-hour is 68Wh (= 5,676 x 12V/1000). This power bank has ~126 Wh, so in ideal world with no loss it will charge 1.83x (=126/68). With some heat loss in the cables and connectors, actual usage will be less but you can assume around 1.5x or so. Hope this helps.

I have not tried to charge 2 iPads at one time but I am sure it could. I have charged my iPad & iPhone at the same time and it does work for that.

I bought 2 of these, 3 months apart. The first works fine with my Surface Pro 1 and 2. The second one I received gives a jittery jumping image which renders it unusable.

I have a Surface Pro 3 - have not been able to make it work - tried multiple power options - splitters into the Surface power supply, USB hub, etc. - no go. Works fine all my other HP, Dell laptops and PCs.

I purchased this adapter for my Surface Pro 2, so I cannot validate your question.

Yes. See here: XIEMIN Portable Charging Charger Cable for Microsoft Surface Pro 3 12 Inch Tablet (Pro 3 Charging Cable)

Yep! I use it on my surface pro 2 to power multiple USB devices. I'm usually running my external keyboard, a flash drive and my mouse off of it. Edit: USB 3.0 speeds are there, I tested it with my USB 3.0 capable flash drive. Speeds will vary depending on your storage device, and how many devices you have plugged into the hub at a time.

I have a Surface RT 8.1 and it works great.I don't know if this will work for the Surface 2 or Pro, there may be a slight size difference.Not sure.

Yes. More than 1 can be charged at a time. My tablet drains faster than cell does when both being charged but still charges both.

I bought it for my surface pro 1. If surface pro 2 has the same display port, then it should work. It actually automatically detects when you connect

The Surface Pro 3 adapter is 35W, 12V, 2.58A. So yes, this should work provided you find the charging tip. I'm still looking for one, if you do please post a link here!

Sorry but it doesn't work with Surface, as Surface is supplied with 12V but the output voltage of this portable charger is 5V.

I don't know for 100%, but I'm pretty sure it will only do one at a time. If you stacked one on the other, the top device may be too far from the pad to charge.

Yes, the chargers are interchangeable between the Surface Pro and Pro 2 :-)

Don't see why it would not work. Works fine on my surface Pro 2. Can't go wrong for the price.

No - this does not have a regular DC outlet and Surface has a proprietary charger. This only has USB and Surface (speaking only for Surface 2) cannot be charged through USB

Yes it is the right aperage for tablets, including iPads, it will charge an iPad about twice
