can You use this as a portable 12V Battery Tender for Car or Motorcycle at a remote site and how long would it last?

The Schumacher PSJ-4424 would not make a very good battery tender, that is not what it is designed for. There are solar battery tenders that would work better and for less money.

It would not work well as a battery tender, it is really only intended to aid in starting vehicles with 13 plus volts to start. It has no trickle or maintain setting, only start. A solar battery tender or 12 volt battery tender hooked to a large deep cycle battery would do better.

Hi there. For camping. and sleeping on the back of my pickup truck. Im using a 100 watt solar pannel connected to a 125 mah battery with a 1000 watt power inverter. I also use a 200 watt heater( smallest I could find) so I wont drain the battery so quick. in other words this one can be use as well in a setu up like mine or if you want to use it in your car battery you would need to connect the 1000 watt amp DIRECTLY from the car battery. DONOT connect it of cigaret outlet. it will blow the fuse since those dont allow to go up to 1000 watts. any questions just ask :)

Assuming the c-pap machine uses a standard outlet and consumes less than 400W continuous power, this inverter should work fine for it. Be aware that not all vehicles deliver power to the 12V outlet when the vehicle is off, so this may not work with the 12V outlet at all unless the vehicle is running. (Alternatively, you can connect it to the vehicle's battery terminals). The duration this inverter can be used without the vehicle on depends on the health of your battery and how loaded the inverter is. I have used this for charging multiple devices for several hours without issue, but this represents a fairly small draw on the battery. This unit is designed to shut off if overloaded and alarm and shutoff if input voltage (from battery) is too low. It's just a guess, but I would expect you'd need to start the car periodically to run the machine all night.

I would not. This is not a heavy duty device. It has small clips and small wires. It is designed to provide power to devices directly from the battery.

I've been using on a 24v aircraft battery (sealed) seems to work alright, they make an aviation "tender" unit...more expensive...no long term effects yet...

Yes. It's fairly low watt and is 12 volt so it should last a long time connected directly to a good battery

If it draws 4.5 amps at 12v, yes- it should do fine if the days are long. What I did was to make one out of a heat pump, regular camping cooler and insulation. It only cost about $50, compared to almost $500 for a commercial one.

Yes, this SunSaver unit will more than handle that job, and its durability is stellar. My company uses them at hundreds of sites all over the western U.S. to keep 12-volt car batteries charged to power remote computer equipment. I highly recommend Morningstar Sunsaver chargers.

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.

my battery tender worked well for a just 2 months, I used it for charge a yuasa battery 12 volts 12 amp hour

Yes, I use this to charge my motorcycle, it's a bit bulky but would be perfect for your application.

I think it would work just fine for the amount of power it would draw. Although you stated that it is a 12 volt system so you could run it directly from a battery unless you wanted to use an AC to Dc adapter.

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!

As long as it is 12volts and provides the required amps, which is stated in sellars description. I use a car battery for mine when I camp. Works fine.

Yes you can with a few millamps lost due to distance. I am using with 15 foot of extension cord from battery tender on a 1990 Chevy Suburban that is used occasionally for towing in the summer. Sets the rest of the year unless my compact car is not in the shop. Works well for long term storage. Just Don,t forget to treat the gas properly for the vehicle if in long term storage.

Yes, you can. It only needs a 12 volt power source; which your car battery is.
