Coffee Trailer Electrical Planning: What to Know Before You Buy Equipment
The espresso machine is not the problem. Everything running at once is.
Read →Search for a mobile bar equipment list and you will find plenty of them. They are all answering a question nobody asked, because the equipment a mobile bar needs is decided almost entirely by which service model it is built for, and the lists never say which one they assume.
A bar built for dry hire and a bar built for full beverage service share a shell and almost nothing else. Decide the model, then the equipment is obvious. Decide the equipment first and you will buy things you never use and lack things you need.
The client supplies and serves the drinks. You may need very little beyond the structure, lighting and power, which is exactly why dry hire scales across several units. Your equipment question is mostly about durability and how fast it sets up.
Now your people are working behind it, so the service line matters: ice capacity, cold storage, somewhere to put empties, and a layout that does not have two bartenders colliding on a busy hour.
Batching moves the work off site and changes the kit entirely. You need cold storage and dispensing far more than you need a full cocktail station, and the equipment gets simpler while the preparation gets more involved.
Draft is its own build: cooling, gas, lines, and a decision about whether the system travels cold or gets chilled on arrival. Retro-fitting draft to a bar that was not planned for it is expensive and usually compromised.
Where the law permits it, this is the most equipment-heavy model and the one with the most requirements attached: handwashing, sanitizing and cold holding among them, depending on your jurisdiction.
Answer those and the equipment list writes itself. Answer them after buying and you will be selling things secondhand.
Work out what a booking is worth and what delivering it costs before committing to equipment, because the kit you choose lands directly in that cost line. The profit calculator takes a booking from its price down to what is left, and the order the decisions go in covers why the unit is the last of them.
