I have a plug-bug, but I found it made the charger too long to fit into many spots so ditched it in favour of a Y cable to go into my macbook charger, and into an Anker 5 port.
I got a regular multi-adapter for the different mains power points, and then spliced together a few of the two-pin mains connectors into a Y-cable (mine has 3 connectors coming off it)
I use one with 3 two pin ends to charge my macbook (it plugs in when you pull out the mac chargers power plug end), my Anker 5 USB port charger, and a li-po battery charger I use for multirotor batteries.

I also carry a 6 inch 2 pin mains cable like the above.
Most trips I use one of those small mesh UA amenity kit bags (

The plugbug wouldn't fit in that, it would only fit in the larger amenity bags - so I found that it was more versatile to use the Y-cable option.
