I just bought a RavPower Super-C Series 26800mAh Portable Chargre so that I can re-charge my Acer Switch Alpha 12 laptop/tablet while traveling.  I can't seem to GET it to work.  My Acer states that it's USB-C port can be used for charging.  I have tried connecting my new RavPower but it won't work.  Perhaps I'm not connecting it properly?  Can anyone please help???  Thanks...

I think we discussed this before, if not the Acer switch can't be charged thru the usb port only with a 19V adapter. Sorry I was wrong   

Seems with the correct adapter the usb c port can be used for charging as explained here. :

Seems it needs to be a 45W adapter with an output of  20V at 2.25A .

Sorry for the confusion, the internet is full of people with the same question looking for a suitable portable charger.
At least now you know what to look for. Remember the 45W is for 1 charge if you need 2 or 3 charges the portable battery PACK will need higher wattage.

And there is still the suggestion for the same price as the power pack get a tablet and use your preset RavPower Super-C Series to charge it.Laptop Magazine did a review.

The article is about two years old. NEWER machines are better and cost less.
IMO you have two choices.
 A. Get a very expensive EXTERNAL power pack.
 B. TRADE you machine in for a newer model.

Either way it will cost you money.
