Ways to charge the Macbook

It doesn't need to be powered off, it can just be sleeping for 5-7W to charge the Macbook.
I use a amazon dual port 24W charger and a 12W apple ipad charger and both charge the Macbook while in use and while sleeping. They each provide 12W of charging power, which charges it about as quickly as my macbook air. I also have a 7W ASUS nexus 7 charger that charges it while it's sleeping and provides a constant power source when it's active.
After 3 hours yes, then the power state will be effectively the same as off, before that point you can expect some power consumption.
Q-6
Still looking for a clear answer here. I have had some very poor results trying to charge from the iPad 12W charger using USB A to USB C. I completely shut down my rMB at 13%. I plugged the rMB in and waited 3 hours. When I powered back up to check on charge, I was at 34%. Seems off to me. Any suggestions here?
All external power banks (or the so called power bricks) with higher capacity (those over 10.000 maH) usually support a 5.0Vdc/2.0A (or 2.1A or 2.4A) DC output. Some external chargers that are 10-12W rated (including Apple's that are supplied with iPads) also have 2.4A outputs.
Now the new 12" rMB's proprietary charger adaptor (one that you plug into the wall outlets) is rated at 14.5Vdc/2.0A. It takes around 2.5 hrs. for a full charge...
Now can someone pls explain (preferably in technical words) as how a 5.0Vdc source can slow-charge a 14.5Vdc load?
If some precautions will be taken the opposite case may be valid (a 14.5Vdc source charging a 5.0Vdc load), but I really cannot understand this 12" rMB slow charging case...

USB 3.1 power delivery is negotiated between the devices and consists, in its basic form, of several power profiles (agreed upon voltage and current levels). The default profile for USB 3.1 is 5V at 2A, and the devices can negotiate higher levels. If the source device agrees to the negotiated higher rate, the target device will get more juice, so to speak. The higher voltage level at higher current will charge the rMB under load, while the lower level will not.
The negotiation is something akin to a I2C bus over the power pins, but I haven't read the full spec yet.
I just picked up a rMB to replace an 11" MBA that I've used for a few years. I'm looking forward to a decent external battery and a car charger to hit the market, hopefully with enough output to charge my rMB under load.
Has anyone found any external battery packs that can successfully charge the rmb? I've read somewhere that Anker ones can....any others?
I'm also looking for a battery pack that supports 'pass through' charging - ie plug battery pack into wall, plug phone into battery pack and both charge at once. I travel a lot and this function saves a lot of time.
My xiaomi and old new trent ones did this but others I own don't.
Ultimately I'd love one that has two usb outputs so I can plug it into the wall, iphone in one usb and macbook in the other and charge all three at same time.
I read Anker's used to support this charge through option but the new ones don't anymore. Can anyone confirm?
Thanks in advance!

Type-C Output: 5V/3A Max
Anyone think this will work?

Slowly about half the speed of the Apple charger with 15W versus Apple`s 29W, assuming it can "handshake" with the rMB, which it should as long as the USB C standard has been applied correctly.
Specifications:
Input (Micro): 5V/9V/12V 2A Max
Input (Type-C): 5V/3A Max
USB Output: 5V/ 2.4A
Type-C Output: 5V/3A Max
QC 2.0 Output: 5V/2.4A, 9V/1.5A, 12V/1.2A Max
I would just ask RAVPower directly on their site and see what they say.

Good point (though I put the 5V/3A thing on my post so you didn't need to bold it in yours)
I checked on their website and found this:
Type-C Input and Output: Introducing the first ever portable charger with USB-C/Type-C charging capabilities. With USB-C/Type-C cables (not included) you can use this portable charger to power devices such as the newest 12 inch Apple Macbook(A1534) and other smart devices that have the corresponding ports.

So I guess you can.

I edited the post as, my initial information was inaccurate, not wanting people to follow that. It should charge the rMB, equally I have read responses that state it will not charge the CromeBook Pixel, equally the Pixel has a larger power supply.
Go buy one and let us know how it turns out.

As a follow up to my post above I did some research on external battery packs and the Anker PowerCore+ 20100 states that it works with retina macbook
http://www.ianker.com/product/A1371011
The Battery Box and the Mini both charge the Macbook - I confirmed with their customer service by email
https://www.getbatterybox.com/
Neither of these have pass through charging so don't suit my needs.
I know that Limefuel ones have pass through charging but does anyone know if these 150X or 200X products are powerful enough to charge the macbook? It says 5V/4.2A max output, which is less than the Anker and Battery Box listed above
http://www.limefuel.com/pages/product-blast
I know Limefuel are bringing out a charger specifically for charging the Macbook but it's not out yet and it's expensive and massive

Massive being the operative word...
Not my first choice for the Retina MacBook, absolutely not flight friendly. I would go with the Anker PowerCore+

Yes I agree...massive and not my first choice either. I'd prefer the Anker as well however I just mentioned them as they are confirmed to work and may suit other people who are interested to know about it.
Also I did mention that the batterbox-mini has been confirmed by their customer service as well as on their website to charge the retina macbook....it is tiny and flight friendly however only charges the macbook 0.7X
https://www.getbatterybox.com/batterybox-mini
I'm hopeful that the Limefuel models I mentioned above can also charge a rmb as they have pass through charging and will fit my requirements however I'm yet to get confirmation from anywhere.
