Anton Bauer VM2 Dual V-Mount Charger

The VM2 charges two V-Mount batteries at once and weighs little enough to travel as hand luggage. A lithium pack such as a 98Wh 8A GO 90 comes up in roughly three hours, and the integrated supply means there is no separate brick to lose.

The useful part is the XLR4 output: it converts AC to 16.7VDC at 4.5A while the charger is working, so the unit powers a camera or accessory with an XLR input at the same time as it charges. Wide 100-240 VAC input, a carry handle, and LED indicators per position.
