This question gets answered badly all over the internet because the same connector appears on both ends of the product line. Separate the two before you spend anything.
The station that actually has one
The Jackery HomePower 3600 Plus carries a NEMA TT-30 receptacle on the unit. Your rig's shore cord goes straight in and the whole coach comes alive: converter, outlets, lights, fridge on electric. Its listing states 3,584Wh of capacity with 3,600W continuous output and 7,200W surge, which matters because a 30 amp RV service is 120V single phase and therefore about 3,600W at the pedestal. It is one of the few stations rated to actually fill that service rather than imitate it.
Be realistic about runtime. 3,584Wh against a rooftop air conditioner pulling roughly 1,500W is about two hours. Against a fridge, lights, water pump and device charging it is a night and most of the next day. The listing states it expands to 21kWh with additional battery packs if that is not enough.
TT-30 in, TT-30 out
A TT-30 input cable plugs a station into a campground pedestal so it charges fast. That is what our BLUETTI TT-30 listings are. The NEMA TT-30 fast charging cable is 60 inches long, fits the AC240 and AC240P, and Bluetti rates maximum input at 2,200W and 2,300W respectively, rising to 2,400W with an expansion battery attached.
A TT-30 output is the 30 amp receptacle described above. The distinction is the whole question, and most product pages do not spell it out.
If you have a 50 amp coach instead
Different socket entirely. The Jackery Explorer 5000 Plus listing states NEMA 14-50 and L14-30R outputs with 7,200W continuous and 120V/240V operation. The 14-50 is the 50 amp RV socket. It does not have a TT-30, so a 30 amp trailer needs an adapter with that unit.
What to check on any station before you buy
- Does the spec sheet name the output receptacle types, or only a wattage? If it only says watts, assume standard household outlets.
- What is the continuous AC rating? A 1,800W station cannot pretend to be a pedestal no matter which plug is fitted to it.
- Is there a high-current 12V output? That path skips the inverter entirely for fridge, pump and lighting loads.
The fixed-install route
If you would rather feed the coach panel than the shore inlet, there are two paths. A manual transfer switch, such as the Jackery 120V 30A unit with its L5-30 inlet, is pre-wired and removes the back-feeding danger of improvised cords. Or replace the panel: the BLUETTI RV5 is a 5-in-1 hub rated to 5,000W at 120V, and the Epanel takes over from the conventional RV breaker panel with monitored circuits.
