I'm really happy with this "one and done" complete ven electrical console. I am running a new, fused 14 awg circuit from my battery to this, then mounting it in my gally for all my 12V and 5V needs. You can see that it accepts cigarette lighter plugs, large USB plugs, and USB connectors. I also really like the digital volt meter and the switch, because I must be careful to NOT run my battery down to 12.5 volts, or else my rig may not start, anchor I may do battery damage. The bolt ever is further helpful because the blue glow reminds .e to turn it off when not in use, since all USB vehicle chargers consume power whenever energized, because they contain a transformer
