Jacked your to house batteries

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.
