Nothing is broken. The power is going to the wrong place.
How an RV's outlets are actually fed
Your coach receptacles are not independent. They run from the shore power inlet, through the converter and the breaker panel, and out to each circuit. When you set a power station on the floor and plug a lamp into it, you have powered the lamp. You have not powered the coach, because nothing has arrived at the inlet where the rig expects it.
That is why the outlets stay dead even though the station shows a full charge and its own sockets work. The station is an island.
Route one: feed the shore cord
Plug your rig's shore cord into the station. For a 30 amp trailer this only works cleanly if the station has a matching outlet. The Jackery HomePower 3600 Plus listing states a NEMA TT-30 receptacle, which is the socket a 30 amp cord is built for, along with 3,600W continuous and 7,200W surge. For a 50 amp coach, the Explorer 5000 Plus listing states NEMA 14-50 and L14-30R with 7,200W continuous and 120V/240V output.
If your station only has household sockets, an adapter will physically connect the cord, but the current is limited by that one outlet and the station's continuous rating. You will be running one large load at a time and switching the air conditioner off. It works for a weekend. It is not an installation.
Route two: fit a transfer switch
This is the proper fix for anything permanent, and the only safe one for a house. A transfer switch moves selected circuits between shore power and the station without any chance of back-feeding. Our Jackery 120V 30A unit arrives pre-wired with an L5-30 inlet, colour-coded wattmeters and a metal indoor cabinet, and Jackery lists it for the 2000 Plus and 3600 Plus.
Before you buy anything, check three things
- What does the station's spec sheet name as an output? If it lists only watts, assume standard household sockets and plan accordingly.
- What is the continuous rating? A 30 amp service is 120V at up to 30 amps, roughly 3,600W. A station rated well under that cannot behave like a pedestal whatever plug is fitted.
- What are you actually trying to run? If it is a fridge, lights and chargers, skip all of this and plug them into the station directly. It is simpler and it works today.
Tell us your rig's shore cord type and what you want running, and we will check the published spec before you order.
