I've got a Pegasus Pocket Power Box with environmental sensor. It has 4 x 12V output ports, 1 x 8V DSLR output port, USB-C to PC port and two dew heater ports. Comes with 1 x cigarette lighter power adaptor cable and 1 x 12V to 12V power port cable. There is some marking on the top of box where I had labels for my gear connections to the various ports.
