Jacked your to house batteries

Do you mean going from a generator to a transfer switch to the battery charger and from the battery charger to the battery and from the battery to an inverter in order to have 120Vac?

What do you mean by Jakery and what is that?

The battery will give you 12Vdc power to the 12Vdc circuits, and the generator will give you 120Vac power to the 120Vac units AKA. air condition, refrigerator, TV and water heater if so equipped and all the 120Vac outlets and will charge the house battery and if it has an isolator the engine battery will be charged as well.

Yes, how overall effective it will be I guess depends on size of Jackery unit. Much easier for us to utilize onboard solar and/or genny when off the grid in our motorhome, one button convenience to enjoy all the creature comforts our rig provides. Unless we are RVing in extreme temps solar covers most of our power demands, sporadic genny usage covers extended convection microwave usage and quick recharging of battery bank with our 100 amp smart charger on cloudy days or when parked in shade.

When boondocking, can I plug the RV into a Jackery unit to transfer amps into the house batteries? I know I loose some power going from 12 v to 110 and back but I am looking for an easy way way to make those available to the whole RV.

In theory this would work, you just need to be careful about exceeding the max power draw of the Jackery -- especially if your house batteries are so depleted that the power converter kicks into fast charge mode. Should probably plug it in early rather than waiting for the batteries get too low.

I have a similar unit, but I use it to power the TV, hotspot, and laptop, saving the house batteries for lights, furnace (if needed) and to start the generator (if needed). So if you can plug some things directly into the Jackery to remove load from the house batteries to keep them from getting depleted, you can avoid the 120V-> 12VDC-> Battery-> Inverter -> 120VAC conversion losses and get more battery lifetime overall.

As many rv forums as I visit, never ever seen " jackery " used in a conversation. Sounds like what my Aussie friend might call a bumper jack.

The Jackery is a lithium battery/inverter. Yes, you can just plug your rig in. Be sure to turn off the AC switches to the fridge and water heater if so equipped.
Your Jackery DC out will not do much more than charge little things, but the AC out will.
A DC to DC charger would be more efficient method to take power from Jackery and put it in your camper batts though. I have not tried this so can't advise how to set it up.

When my GC batts finally die I will not replace them with lead. I will get a portable like your Jackery and that will be the on-board DC power for the camper. Lighter and in the winter or hot summer I can just take the batts inside to more mile temps.

I had to do a search myself to see what the OP is talking about since the OPs title and post is very confusing to say the least.

So, the "Jackery" is nothing more than a "jump box" with a built in battery plus an 120V inverter. Nothing special here.



Found HERE

From what I gather, the OP is wanting to "substitute" the Jackery jump box for a generator and/or house batteries.

At $1600 it is an insanely expensive jump box and the largest one they sell is a 1800W model.

First and foremost, it is not a generator, it is a battery and inverter and has battery limitations.

Second, it has a very limited battery capacity of 60.9Ahr which isn't going to be anywhere close enough to "replace" your house battery unless you are talking about a group 24 RV/Marine battery.

They claim 1534Whrs of use, that is not really useful and one of the questions asked this..

" Q2: How to know the working times for my device?

A: Working time = 1534Wh* 0.85 / operating power of your device. "

so, essentially 1303.9/ wattage of device(s) in use.

A 1000W 120V draw will get you 1.3hrs of run time.

A 100W 120V draw will get you 13 hrs of run time.

And keep in mind, you will have to recharge this device, when the battery is discharged all the fun is over.. At least with a gen you just add some more gas and your golden for hrs at a time on a tank of fuel..

They have a 2000W/2000Wh device for $2000 -- that's 160Ah@12V, so that's not insanely expensive when 200Ah of BattleBorn Lithium batteries cost $1800 (and that's just for the batteries, no charger, no inverter, etc that you get with the Jackery).

Losing 15% to power conversion losses is not terrible a $500 AIMS 2000W inverter has 10% loss at full power.


It's definitely not a generator, but it's not useless waste of money either if you want a decent amount of portable power that you can carry around with you.

Never heard of it either.

I was thinking Jack "Donkey-ery" but use a different word for donkey.

Back to the OP: If you have a jump starter with built in inverter, yes, you could plug it in and it would charge your batteries...just not very much before it's dead.

If you don't have one already, far better to add an extra battery to the trailer and/or a solar panel.

Losing 15% (inverter loss)to get to 120V and then an additional 15% (Converter loss) to run 12V devices is 30% loss.

In your example of 160 Ahr at 12V that is a 48Ahr capacity loss giving you only 120 Ahr to use.

Makes using a BattleBorn battery direct a much better choice.
