would this keep a 12v lightbulb burning with 12v car battery

I have measured the voltage to the battery on my trailer and this unit maintains 13.5 volts. I run a winch to load and unload cars from my trailer and find I have plenty of power and the voltage doesn't drop. From that I can only assume that it would operate a 12 volt light with no problem.

Yes it is It keeps your 12 v going, handles the 110 v, and keeps your battery charged. Hope this helps

It should. I attached it directly to my Jeep battery to provide a 12 volt source of power that would be available even when the ignition is off. We mostly use it to charge cell phones and camera batteries when we are camping

should work fine off a battery and using this to keep it charged.. shouldn't used it directly because of voltage fluctuations with clouds and weather.. will put out up to 6 amps in good sunlight...

Yes if you want them both on the same switch. I used it to wire up to the battery on my four wheeler. My only suggestion is you run it to a power source that doesn't constantly have power to it. I used the 12 volt cigarette lighter for mine. Reason being the small light on the switch doesn't stay on unless the key is in and on therefore not draining my battery.

Make sure the bulb can handle at least 3 volts, its a 3 volt battery max. .

A very good product I would recomend this product to charge and maintain a 12Volt car battery.

Short answer, yes. Just wire it up like how you would a light bulb; make sure to add a resistor, this thing only take 12volts DC only.

Hi,yeah it will because it needs power to keep it activated but minimal amount 12volt DC .

Yeah. If the battery gets used up just plug it via usb to your computer, 115vac, car usb converter... Lights go all disco too. Pretty cool imho

If your using one 12 volt car battery out of the car it won't supply that current for any useable amont of time even if the converter was capableof doing that, which it is not. It could maintain 800 watts continuous if the battery was in the car with the car running maybe even 900 watts,but that's it. As far as the connection to the battery I'll reserve the "duh" and say: positive to post marked +, negative to post marked -.

NO! That would draw too much power and fry this thing and likely start a fire as it is no properly fused. Get a power inverter that ties directly into the battery instead.

In theory that would work, but if the battery is discharged it will probably burn the module up trying to maintain the current

Yes, provided the torch or lantern battery is 6V. Many 6V lanterns use 4.8V bulbs because they are brighter, and give better output as the battery voltage falls as it discharges.

Hi Ai:According to the specs for your light, this battery should work fine.Just make sure to check that the volt and mah are compatible. You can go a little lower on volt and mah but not higher otherwise you risk damaging the light.RegardsKathy

the lock uses very little power, I would assume a 12v battery would work fine, I think creating a circuit similar to an emergency light would work without issues

It will help to keep the battery charge... it does not have enough amps to run the engine directly. You will have to rig together your own velcro setup, but it is do able.
