would this be decent to run a 12v 4a stereo i built for camping? how long would it be able to power something like that?

If by 4a you mean 4 amp current draw then this 12 amp hour battery could run in for a max of 3 hours. About half that would be more realistic unless the power draw was less with lowered sound levels giving reduced amp needs. I run a ham radio transceiver with mine which pulls about 1.5 amps on listen and 10-12 on transmit. I have used it for over 2 hours of mixed use and it was still going.

I would say so! I swear by this thing. I keep it with me at all times for my laptop, cellphone. It had enough power to kill my Subaru car battery over night even though the switch was turned to off. Just make sure to unplug it from your car outlet immediately after you are done using it. Have fun camping!

It'll run fine off of a 115 volt outlet, won't trip it. We run it off a small 115v 2000 watt portable generator out in the field.

It depends on what your purpose for the device is. I'm currently using this to power a small speaker and it works excellently. One note worthy benefit is that you have a voltage adjuster on the unit rather than being stuck strictly to 12 or 5 volts.

I'd say yes. It has a 120 volt transformer for DC input and also it will run on SIX batteries (the large D size). I have been using it in my camper for 3 years. Nice unit.

Have one over a year in my rv. This will not draw 1800 watts with a long power cord. runs my microwave,tv and satellite receiver no problem. Used a 35 amps battery charger to charge my boat battery

You can use either power supply ac/or dc with this product, because it comes with an adapter to do both. I guess if you needed it on your boat or camper you could do so with no problem.

Most definitely can be used with a 12v DC supply. Just be certain the supply is capable of delivering adequate power for the radio. Reference the specifications on-line.

Yes, I think it would be fine. I use it to power my weed wackerpPlus it's long enough. Hope this helps

The instructions say that it draws 18 watts. So a 12V 2 amp (or higher amp rating) power supply would run it.

I plug an acoustic guitar into it for outdoor weddings where there is no power. Used it twice and was fine and loud enough. Takes about 10 seconds to get moving. Planning on using it for a couple weddings this summer. The battery power was good. If you're looking to use it as a stereo, I don't know how to answer. Hope this helped.

I use it for a trailer with 12 batteries attached to it or you can use it plugged into a car. Works both ways as long as it gets 12v as input it will convert it for you.

It is designed to deliver 12 volts at 45 amp peak to charge a deep cycle battery to run items in a rv I would suggest reading the spec sheet to make sure it fits your needs

Sure--- as long as what you are trying to power needs 5volts and takes no more than 2 amps, it should work.

As long is it's DC and you have a power socket it'll work. It only uses about 7amps of power.

I powered it up on my bench with a bench supply. There is no reason that a 12 volt battery pack would not work. Pay attn to + and -. Not sure how long it would last. You would have to look a the current draw of the desplay.

It does work well for portable generators, note that you will need to by and attach the appropriate connectors. The wires are stranded pure copper.
