DC Powerpack end view
On the left is a marine grade power receptacle that is an upgrade from the generic receptacles normally found..
The next device to the right of the power receptacle is a LED battery power level indicator, with a mating plug for my Genius smart-charger.
The 110 volt flush mount outlet, is wired to a small 12 volt to 110 volt inverter mounted under the cover, suitable for powering a laptop, wall-wart chargers, etc.
Its worth stating that all these devices are wired through a master shut-off switch, effectively powering down the entire powerpack when not in use.
