Perhaps the astrophotography accessories can help:

I understood that accessories that transform 12v into 7.6V for example are a) expensive and b) generate a lot of heat, losing 20% of the power to heat.

Not sure if the route battery => 220V AC => 7.6V DC would be better though.

There is also the possibility to use the 12v car connection to transform to 7.6V:
