I have an extra USB-a to USB-c cable.

When I travel, I take my ipad charger. Can I use that charger and plug in a usb a to c cable and charge my macbook?

The usb-c that came with the computer is part of my monitor/desktop doc setup. Kinda a pain to disassemble all that every time I travel.

Yes, I do over night with my iPad charger works fine.

I also sometimes use a regular iPhone charger, but sometimes it won't quite be charged in the morning.
 
Yes, works well.
I use an Anker PowerPort 10.
I'm travelling ATM, so charge my Macbook, iPhone, AW, wife's iPad & iPhone, 2 golf GPS's, camera battery, all from the one charger.
 
Have the following 3A USB-c to USB-a cables that all work perfectly well.
-Belkin
-Monoprice
-China knock off

Wall Chargers
-2.1A: Provides very little charge while using during the day. Windows 7 & 10 under VM will drain the battery.
-2.4A: Will charge slowly but efficiently, with VM running it will trickle charge so I don't lose any battery by end of day.

Really waiting for more 3A chargers to pop up on the market, Ideal charger as I travel often, with interchanable plugs.
-3A USB-A or USB-C
-2.1A USB-A (phone/tablet
-2.1A USB-A/C to charge power bank

If all three ports could be simultaneously utilized, i'd be over the moon.

I assume you can charge rMB overnight w/ 2.1A? Which 2.4A charger do you use? Thanks.

I wound up getting this charger recently, it's got a USB-C port that will charge an rMB at full speed and has three 2.4A USB-A ports: https://www.amazon.com/Charger-Delivery-Macbook-Chromebook-Samsung/dp/B01ET7SDXK

I use the Anker USBC/A cable for charging frequently, especially when travelling.

Results see to vary, and it may related to the generational age of a charger. I have an older 2.1A charger that barely maintains charge on my rMB, and I have other more recently built 2.4A chargers that reliably deliver a good charge. Granted, if you're really working the rMB a 2.4A charger may not be able to keep up, but for low-effort stuff like web surfing it charges while in use, and will do a full charge overnight with aplomb. I suspect it's something generational as a 2.1A vs 2.4A (10W vs 12W) difference is too small to generate the effect seen, and I believe the 2.1A charger for some reason is staying at a low current delivery and not switching over to the higher current.

IMHO the ability to charge (or just maintain battery level) from a 2.4A USB port is a huge selling point for the rMB for travelers. Not only does its size fit well on an airline tray table, but you can simply plug it into the seat back USB port and work through the flight with no worries of draining your battery.
 
I see. Thanks.

Thanks for the info.

Purchased 3 weeks ago for ($12)
1x Type-C- 5V 3A
2x Type-A 4.8A, (2.4A per port)
All ports can be used simultaneously.

Pros
-charge my macbook 10% to 100% in 2h30 (WHen in sleep mode or off)
-charge power bank + iphone
-small (will post photo next to MB 29w)


Cons
-Small amount of effort required to flick the prongs out . no big issue for most as long as you're hands are not lubed up.
-still looking for something with interchangeable adapters for travel abroad.

can you simply plug in a type-c to type-a cable to USB port on the airline seat and charge rMB directly?
 
Yes, though in my experience the ports don't supply much current, so whether it charges or just reduces battery drain depends on how heavily you're taxing the system. Either way it's better than not having any juice.
