Cheap laptop chargers are excellent candidates for the HV version. /Bingo --- End quote --- Those are the wider input versions I spoke of and those are the ones you don't want. The combination is less efficient than just using the correct brick. |

The input power is the 12V battery used on the boat. |

The 12v on a boat may not be "clean", I suppose it could be up to 13.8v or whatever is the charging voltage. A HV (wide input range) picoPSU will regulate the 12v as well, but the output current on 12v will be fairly small, something like 10-20A or around 100w You'd probably be better off buying an inverter to convert 12v to AC and then use a regular gold/platinum efficiency psu ... you lose some energy through the conversion from 12v to AC but you can probably top up the battery (maybe also use some solar panels throughout the day) |

Very easy mod - just identify the high voltage DC output from the rectifier and tap into it. |
