The short version: The HomePower 3600 Plus is the Jackery with a native NEMA TT-30 outlet, so a 30-amp trailer plugs in with its own shore cord and no adapter. The Explorer 5000 Plus is bigger and does 120V/240V through NEMA 14-50 and L14-30R, but those are different sockets. Everything smaller means running individual appliances on extension cords, or wiring in a manual transfer switch.
What a 30-amp cord actually is
A 30-amp RV shore cord ends in a TT-30 plug: three prongs, 120 volts, up to 30 amps. That is a ceiling of roughly 3,600 watts. It is not a 240V connection, which is the single most common misunderstanding when people start shopping for backup power. A 30-amp trailer is a 120V appliance that happens to draw a lot.
So the question is not whether a power station is "big enough for 30 amps" in the abstract. It is whether it can supply the watts you actually draw, through a socket your cord fits.
The direct answer: HomePower 3600 Plus
The HomePower 3600 Plus carries a NEMA TT-30 outlet on the unit. Plug the trailer in, and the whole coach is live: converter, outlets, fridge on electric, lights, fans.
The numbers behind it: 3,584Wh of EV-grade LiFePO4, 3,600W continuous with 7,200W surge, and 6,000 cycles. It runs at about 30 dB, which is quiet enough to sit inside the camper overnight. Add up to five Battery Pack 3600 units to reach 21kWh, or run two stations in parallel for 240V.
What that buys in practice: 3,584Wh will carry a residential-style RV fridge, lights, water pump, phone and laptop charging, and a furnace fan through a night and well into the next day. It will not run a rooftop air conditioner for long, and nothing this size will.
Where the air conditioner fits in
Be realistic here. A 13,500 BTU rooftop unit draws somewhere around 1,300 to 1,700 watts running, with a much larger startup spike. The 3,600W continuous rating handles that draw, and the 7,200W surge covers a typical start, so it can run. The limit is capacity, not power: at roughly 1,500W, 3,584Wh is about two hours of air conditioning before the station is flat.
If air conditioning off-grid is the goal, you are looking at expansion batteries, a lot of solar, or a different approach entirely. If the goal is a quiet night with the fridge, fan and lights running, one unit is plenty.
What about the Explorer 5000 Plus?
The Explorer 5000 Plus is the larger machine: 5,040Wh, 7,200W continuous and 14,400W surge, with genuine 120V/240V output. Its sockets are NEMA 14-50, NEMA L14-30R and NEMA 5-20.
Note what is not on that list: TT-30. A 14-50 is the 50-amp RV socket, and an L14-30R is a twist-lock 30-amp 240V outlet, which is not the same thing as a TT-30 even though both say "30". If you have a 50-amp coach, the 5000 Plus is the natural match. If you have a 30-amp trailer and buy the 5000 Plus, you will need the correct adapter.
If you already own a smaller Jackery
You have two honest options.
Run appliances individually. Skip the shore cord and plug the fridge, the fan and the chargers straight into the station. This is how most people use a Explorer 2000 v2 or a HomePower 2000 Plus v2 in a camper, and it works fine. You lose the converter charging the house battery, and you lose anything hard-wired.
Wire in a transfer switch. The Manual Transfer Switch 120V 30A is pre-wired with an L5-30 inlet and is listed for the 2000 Plus and 3600 Plus. It is aimed at backing up house circuits rather than a trailer, but it is the same principle and it removes the back-feeding danger of improvised cords. For the 5000 Plus there is a 240V 50A manual transfer switch and an automatic Smart Transfer Switch.
Keeping it charged
A station that runs a trailer overnight needs to refill during the day. Two routes worth knowing: the DC-DC Alternator Charger pulls 600W from the tow vehicle while you drive, roughly 1kWh every two hours, and the SolarSaga 500 X is a 500W folding array for parking up for a few days. The 10m DC extension cable means the panels can chase the sun while the station stays in the shade.
FAQ
Can I use an adapter to plug my 30-amp cord into a Jackery?
Yes, with the right dogbone adapter into a standard outlet, but remember that a household 5-20 outlet on the station is limited well below 30 amps. The adapter does not raise the ceiling, and you still have to watch total draw.
Will it run my air conditioner?
The HomePower 3600 Plus can start and run a typical 13,500 BTU rooftop unit, but expect roughly two hours from a full charge with nothing else running. Add expansion batteries if you need more.
Does the HomePower 3600 Pro Max have a TT-30 outlet?
Jackery lists the TT-30 on the 3600 Plus. The Pro Max is specified around 4,000W at 240V or 2,000W at 120V from one unit and is aimed at whole-home backup through a transfer switch. If the TT-30 socket is what you are buying for, get the 3600 Plus.
Can two units give me 240V?
Yes. Jackery lists 240V output when two HomePower 3600 Plus units are connected. The Pro Max does 240V from a single unit.
