    110 to 12v

    I would never make it as an electrician. how does everyone run there 12v stuff at home? All battery or is there a decent converter out there. Everything I see online is for cell phones etc. I want to be able to run the pump for my blue bowl straight from the 110 outlet. help

    Get a small 12v battery and run it with a small charger like 2 amp or more while running the pump, Thats what Im running currently with my blue bowl.

    The best way is free.
    Computers run off of 12 volts DC and they can be power hungry.
    The power supply is modular and they come in all different sizes.
    Watts divided by volts equal amps.
    Good ones have a cooling fan built in.

    Your local computer shop might give one to you for free out of an old junk computer.

    If you can live with 5 amp dc output this Wagan unit works well for me. Very well built and true output. Beware it took going through a lot of cheep plugin converters to find one where the output matched the specs and well built enough to sustain a constant draw.

    IMAUDIGGER has a good idea in the computer power supply. Don't take one out of a cheap computer like an eMachine or an Acer - their cheap power supplies fail before anything else. Computer power supplies typically have a low tolerance for continuous full draw and some use a 24V tap instead of the 12V. Most are rated 2 amp continuous so look for something around 800 - 1000 watt continuous output if your pump needs more than 2 amp (probable).

    The new units have 3 amp 750 GPH pumps with a 5 amp fuse.

    I have a thousand (Literally) power supplies. PM me your address and the info on the pump and I will send you what you need. (Serious) Send a picture of the pump label and connection.

    A standard automotive battery charger should power a bilge pump with no problem and you probably already have one of those. I hook my pump to a car battery to buffer the load and and then connect the charger to keep everything topped up.

    I just use my car jump start box to power my pump and it last for hours of constant running. I like the mobility it gives. Just plug it in to re charge when finished using. Don't think you can plug in 120 volt to recharge and still get the 12 VDC out the cables but I have never tried. Would think that it would have a built in interrupter switch of some sort that when its plugged into 120 AC the DC will not be available. Next time I am out in shop, I will have to prove that theory to myself.

    This is exactly what I have done in the past - using a charger to charge a battery, and power the pump from that battery.

    I have a small 12v off-the-grid setup at the house (3 solar panels, 4 deep cycle batteries powering a 12v freezer) and in the winter I use a Battery Tender brand battery charger at night to boost the charge in the battery bank, so when I need to I also repurpose that Battery Tender unit to help run a pump for a blue bowl. I can say the Battery Tender products are good and the tech support is also very good.

    36 amps, plenty of power.
    These are built for continuous use.

    If it's old, I'll dig it, dive on it, detect it or sometimes when I get lucky just bend over and pick it up.

    I use a Harbor Freight 3 in 1 power pack, costs about $40. I just leave it plugged in to charge and it will run forever.
