We also have a solar panel (35w) which I haven't got hooked up yet. I think the only battery drain I would have would be (like you) the lights in evening and charging. I would only need about 4 days of battery life, so maybe with the solar panel I'll have enough ooomph
If you have a water pump it will also use 12V power. As will a furnace if you need to warm up on a cold night. If the fridge in your trailer has any digital controls it will also use some 12v power even when running on propane.


To help you understand the answers given to some of the questions you have asked regarding power on this thread there is a site called The 12V Side of Life that you may find helpful.

Emily, that's good to know. Thank you for looking into it! The inverters I've been looking at are around 1000 watts... so maybe they would charge faster...

I still don't have the solar panel quite arranged, but hope we can do that this week. If we don't manage to get an inverter sorted, I guess we could always charge up in the car... maybe with solar hooked up to that battery? The car only charges with the key on, and I've been nervous in the past about draining the battery out in the boonies.

This will be my first trip in the Lil'Bigfoot, and in spite of all efforts, I'm sure we'll find all kinds of things that need to be changed or fixed. But that's what the shakedown cruise is for, right?

USB based charging rates are usually limited by the devices circuits to about 2.1 amps (Check on the charger, it's always there) 2.1amps x 5 volts = 10.5 watts, a minimal amount for almost any inverter. A larger inverter will have no effect on how fast these devices charge. Larger devices, such as computers, will draw more, again, check the value on the devices charger for maximum wattage requirement.

If you just need to charge something via USB, it is much simpler and cheaper to install a cigarette plug into the 12V system. Then you use the same USB adapter as in the tug.
