Search results for a mobile coffee cart and for a coffee trailer answer different questions. A cart is capped by the outlet it borrows, the small tank it carries, and a single-group machine — roughly 25 to 40 drinks an hour. A trailer carries 240-volt service, code-sized tanks, and a two-group machine.
A mobile coffee cart is a compact unit you push into a space someone else already powers. That is the whole design, and it is also the ceiling: the outlet you are handed, the tank you can carry, and the counter you have to work on. A coffee trailer removes all three limits by bringing its own.
Three numbers decide what a setup can actually serve. The circuit — a standard 120-volt, 20-amp outlet supplies about 1,920 watts of continuous load, and a single-group commercial espresso machine can take 1,500 to 1,600 of it. The tanks — most jurisdictions size the waste tank as a percentage above the fresh tank, and the percentage is not the same everywhere. The pace — one barista on a single-group machine lands somewhere near 25 to 40 drinks an hour, and that sets your ceiling at a busy event.
| Constraint | Where a cart tops out | What a trailer carries |
|---|---|---|
| Power | Borrowed venue outlet or a ~2,000W inverter generator; single-group only | Onboard generator and 240-volt wiring; two-group machine |
| Water | Small tanks; sinks depend on a local exemption you may not get | Full fresh and waste tanks and room for a three-compartment sink |
| Pace | ~25–40 drinks/hour, one barista | 60–120 drinks/hour with two baristas |
| Siting | Indoor footprint, but cannot carry the service or sinks most menus need | Outdoor siting and a tow vehicle, carrying the full build |
Eastcoast Concessions builds coffee and espresso trailers, not coffee carts. Sizes and what pushes a build up the range are covered in food trailer sizes and how to choose one.

Power is the first hard wall on any mobile coffee setup. Do the arithmetic before you pick equipment.
A 120-volt, 20-amp circuit carries 2,400 volt-amps on paper. The National Electrical Code derates continuous loads to 80 percent, so plan on roughly 1,920 watts. A Rancilio Classe 5 USB single-group is rated 1,600 watts on 110–120 volts and asks for a 20-amp circuit and a NEMA 5-20R receptacle. A Nuova Simonelli Appia Life single-group on 110 volts draws 13 amps, 1,500 watts, on an ordinary 5-15 plug. Either one takes most of your circuit before the grinder is plugged in.
“Single-group runs on household power” is not a rule, though. La Marzocco’s Linea Classic single-group is a 208-to-240-volt machine, 2,500 watts, on a NEMA 6-20 plug. Read the spec sheet for the exact model, not the category.
Two-group machines are where borrowed power stops working. A 240-volt Linea Classic two-group pulls 4,600 watts at 22 amps; a Rancilio Classe 5 S two-group pulls 4,300 watts on a 30-amp circuit. A Honda EU2200i inverter generator puts out 1,800 watts continuous and 2,200 peak, at 120 volts only — the wrong voltage and roughly 40 percent of the wattage. That gap is what a trailer’s own generator and 240-volt panel exist to close.
Then add everything else. Grinders run about 350 watts for a Mazzer Super Jolly and 580 for a Mahlkönig E65S in US trim. Motors surge on startup too, which is why a breaker holds all morning and then trips the moment a fridge compressor kicks in while the boiler reheats. Venues rarely help: the National Folk Festival includes one 20-amp circuit in its vendor fee and bans generators outright.
The FDA Food Code, section 5-401.11, sizes a mobile unit’s sewage tank 15 percent larger than the water supply tank. New Jersey adopts that language nearly word for word in N.J.A.C. 8:24-5.4, and Pennsylvania says the same. California does not: Health and Safety Code section 114240(b) requires 50 percent greater, never below 7.5 gallons. A unit built to the 15 percent ratio is out of compliance the moment it works in California.
Minimum gallons are local too. The FDA Food Code sets none. New York City sets 40 gallons for a food truck and 10 for a pushcart.
Sinks are where coffee gets unusual treatment. New York City classifies brewed coffee as Class D, and its requirements table calls for potable water and a waste water tank but no ware washing sink and no hand wash sink. Oregon runs the other way and requires a handwashing sink on Class II through IV mobile units, with 5 gallons available at the start of the workday. California lets a non-hazardous-food unit skip the warewashing sink only if utensils are sanitized daily at a commissary, and never lets you skip handwashing. A setup that is legal in Manhattan can fail in Portland — which is the argument for carrying the sinks rather than qualifying for an exemption.
Equipment sources put a single-group machine at under 40 drinks an hour, or 25 to 35 with one barista, depending on who you ask. Two-group figures land at 40 to 80 an hour in one source, and 60 to 80 with one barista and 100 to 120 with two in another. The numbers disagree at the edges; the shape does not.
Run it against a booking. A 200-guest morning event where most people order once is about 200 drinks. At 40 an hour that is five hours from a single barista — longer than most morning windows. Two baristas on a two-group machine cut it to under three.
Counter space is the physical reason. A single group wants 18 to 24 inches; a two-group wants 28 to 32. New York City caps a non-truck mobile food vending unit at 10 feet long and 5 feet wide including wheels and axles, and real event carts run smaller — a common model measures about 63 inches long and 30 wide at 220 pounds. Two baristas and a two-group machine do not fit in that.
Carts get into places a trailer never will. A unit weighing 95 to 220 pounds goes through a doorway, into a freight elevator, and onto a hotel mezzanine. That access is real, and it is the one column where a cart wins.
Everything else on the list is what a cart is short of: 240-volt wiring, a generator sized for it, real fresh and waste tanks, and room for a three-compartment sink where code requires one. Coffee trailers commonly run 6 by 12 up to 8.5 by 16 feet. Check the ratings before buying a tow vehicle — a Class III hitch tops out at 5,000 pounds, a Class IV at 12,000. The cost side of that is covered in what a custom concession trailer costs and in our guide to what a coffee build costs and how to choose one.
Eastcoast Concessions builds coffee and espresso trailers, made to order in Wayne, New Jersey. It does not build coffee carts. Coffee trailers start at $32,000, with most builds between $45,000 and $75,000, and roughly 8 to 14 weeks of build time. Every trailer is collected in person from the shop in Wayne. Equipment is NSF-compliant and the build is made to the applicable code, but you supply your health department’s requirements, you obtain the approvals, and the inspector makes the final call. Every other dollar figure on this page is industry research, not Eastcoast Concessions pricing.
A single-group machine often can. A commercial espresso machine rated 1,500 to 1,600 watts on 110–120 volts fits a 20-amp circuit, which supplies about 1,920 watts of continuous load. Adding a grinder, a fridge, and a blender does not. A two-group machine cannot: that needs 240-volt service and a unit built to carry it.
It depends on the jurisdiction. The FDA Food Code and New Jersey require the waste tank to be 15 percent larger than the fresh tank. California requires 50 percent larger and never below 7.5 gallons. New York City sets a 10-gallon minimum fresh tank for a pushcart.
No. Eastcoast Concessions builds coffee and espresso trailers, made to order in Wayne, New Jersey. Sink rules are one reason the trailer is the safer buy: New York City treats brewed coffee as Class D and requires no warewashing or handwashing sink, but Oregon requires handwashing on mobile units, and a trailer carries the sinks either way.
