Looks like a much better option to the flimsy cig lighter plug.
The cigarette lighter socket has become a defacto standard for 12 volt
power. But it is not an exceptionally good and reliable design for that
purpose. It wasn't designed to be a high current connector.
For high current and reliable connections, I have always used the
standard Anderson Powerpole line of DC connectors. I have literally
thousands of these in the field.
These are designed in different sizes to allow for fusing and prevent
plugging in high current devices into receptacles fused and wired for
low current applications that would blow a fuse or have undersized wiring.

If you look around that site you will find wall jacks and bulkhead jacks
including waterproof jacks.

These plugs and jacks are absolutely the right way to do reliable high
current DC connections. A lighter jack is not, and I'd argue that a high
current drawn through a lighter jack is a fire hazard at least and hard
on the device at best due to losses in the design of the plug and jack.
And as always, size the wiring accordingly for low resistive losses with
a high current device. This will be much larger wire gage than the
sizing for a 125 volt AC circuit will specify. A lot larger.
