If you're running a food van or market stall and the mains isn't an option, an ex military generator solves the power problem without festival-tent noise or diesel bills that eat your margin.
- A 5kVA diesel genset burns roughly 1.2 litres an hour at half load - enough for a full market day on one tank.
- Silenced or canopied ex military generators for market traders sit around 65dB at 7 metres, which meets most organiser noise caps.
- Petrol suitcase units under 20kg suit single-stall traders; trailer-mounted 10kVA+ sets suit multi-stall pitches - Buy accordingly.
- Unsilenced ex military diesel sets without RCD protection are a Skip for any public-facing food pitch in 2026.
Why this matters
Most market traders and street food vendors buy a generator once and live with the wrong decision for years. Too small and your fridge trips out when the griddle kicks in. Too loud and the organiser moves you to the far end of the field next season. Ex military generators for market traders solve both problems if you match the fuel type, noise rating and wattage to the pitch - not just to the lowest price on the listing. There's a full spec breakdown in the ex military generators for off-grid power guide if you want the wider off-grid picture beyond trading.
Who this is for
This is for people running a food van, street food stall, market pitch or mobile catering setup who need reliable power away from mains hookup - fridges, griddles, till systems, lighting - without breaking noise rules or refuelling twice a day. It's not for backup home power or camping trips; those loads and duty cycles are different.
What to look for in ex military generators for market traders
Fuel type
Diesel gensets cost less to run per hour and diesel is easier to source at trade counters and truck stops than petrol. Petrol units start easier in cold weather and weigh less, which matters if you're loading a suitcase generator by hand every market day.
Noise output
Most UK market and festival organisers cap generator noise somewhere around 65-70dB measured at 7 metres from the unit. An unsilenced ex-army genset can run 10-15dB louder than that, which is the difference between trading and getting moved. Canopied or silenced sets close that gap.
Running watts vs surge watts
A fridge compressor or griddle element can draw 2-3 times its running wattage for a second or two on startup. Buy on surge capacity, not just the running figure printed on the genset's plate, or you'll trip the breaker every time two appliances start together.
Weight and portability
Ex military generators for market traders often started life towed or carried by two people in uniform. A 2kVA petrol suitcase set at around 18kg is a one-person lift. A 5kVA diesel set is a two-person job or a trolley job - factor that into your setup time.
Condition and grading
Ex-army gensets get sold used, reconditioned, or as new old stock depending on how they left service. Ask for hours run and last service date before you buy - a low-hours reconditioned unit beats a cheap high-hours one every time on reliability.
Electrical safety and RCD protection
Food vendors working public events need RCD (residual current device) protection built in or fitted, plus current PAT testing on the unit and leads. This isn't optional at most organised markets - check it before pitch day, not on it.
Top picks by generator type
Petrol suitcase genset (2kVA) - the grab-and-go pick. Weighs around 18kg, one-person carry, no towing needed. Fine for a coffee cart or single fridge-plus-till setup. Buy if you're running one stall and one appliance category.
Diesel genset (5kVA) - the workhorse. Burns roughly 1.2 litres an hour at half load and covers an 8-hour trading day on a single tank. Handles a fridge, griddle and lighting together without tripping. Buy for full-day food van trading.
Silenced or canopied diesel genset - the market-safe pick. The canopy knocks noise down to around 65dB at 7 metres, which clears most organiser limits. Costs more upfront but keeps you off the noise blacklist. Buy if you trade at managed markets or festivals with sound restrictions.
Trailer-mounted genset (10kVA+) - the multi-stall pick. Heavy, needs a tow vehicle, but supplies several stalls off one unit. Worth it only if you're the one supplying power to neighbouring traders. Consider - not a first purchase for a single stall.
Unsilenced, uncanopied ex-army diesel set - the one to skip. No RCD, no noise damping, and hours-run history usually unknown. Keep a 50 cal ammo tin in the van for spare fuel filters and spark plugs instead of relying on this type to run trouble-free. Skip for any public-facing pitch.
“If the genset can't run your fridge and griddle at the same time, it's the wrong genset for market day.”
What to avoid
- Unrated or unknown-hours ex military generators sold without service history - you're buying someone else's future breakdown.
- Petrol sets for full-day trading - the tank runs dry mid-afternoon and petrol isn't always available on-site.
- Any genset without RCD protection at a public event - some organisers will refuse your pitch on the day, not before.
Fuel storage matters as much as the genset itself - the military jerry cans for off-grid fuel storage guide covers safe transport and decanting if you're carrying spare diesel or petrol to the pitch.
Verdict comparison
| Type | Fuel | Noise (approx) | Weight | Verdict |
|---|---|---|---|---|
| Petrol suitcase 2kVA | Petrol | Moderate, uncanopied | ~18kg | Buy - single stall |
| Diesel 5kVA | Diesel | Moderate, uncanopied | Two-person lift | Buy - full-day trading |
| Silenced/canopied diesel | Diesel | ~65dB at 7m | Heavier, canopy | Buy - managed events |
| Trailer-mounted 10kVA+ | Diesel | Varies by canopy | Requires tow | Consider - multi-stall only |
| Unsilenced, no RCD | Diesel/petrol | Loud, uncapped | Varies | Skip |
FAQ
What's the best ex military generator for a market stall in 2026?
A silenced or canopied diesel genset around 5kVA is the best all-round choice for 2026 market trading - it covers a fridge and cooking equipment for a full day and meets most organiser noise caps around 65dB at 7 metres.
How much does an ex military generator cost?
Pricing depends on kVA rating, condition grading and whether the unit is silenced - check current listings rather than assume a fixed figure, since a used unit and a reconditioned unit price very differently.
Is diesel or petrol better for market trading?
Diesel wins for full trading days because it burns roughly 1.2 litres an hour at half load and is easier to source at trade counters. Petrol suits lighter, shorter setups where portability matters more than runtime.
How loud can a generator be at a market or festival?
Most UK market and festival organisers cap noise around 65-70dB measured at 7 metres. Unsilenced ex-army gensets often run 10-15dB louder than that, which puts you at risk of being moved or refused a pitch.
Do I need PAT testing for a generator at a food stall?
Yes - most organised markets require current PAT testing on the generator and its leads plus RCD protection before you're allowed to trade. Check this with the organiser before pitch day.
How long will a generator run on a full tank?
A 5kVA diesel genset at half load typically runs around 8 hours on a full tank, which covers most single-day market trading without a refuel stop.
Can I use an ex military generator at a food festival?
Yes, provided it meets the noise cap and has RCD protection fitted - canopied or silenced ex military generators for market traders are built for exactly this kind of continuous field use.
What size generator do I need for a coffee van?
A 2kVA petrol suitcase unit covers a single espresso machine and till setup. Add a fridge or second appliance and you're better sized at 5kVA to cover surge wattage on startup.
One last thing
The spec sheet number that actually matters on ex military generators for market traders isn't the headline kVA rating - it's the surge wattage figure, because that's what decides whether your fridge and griddle can start together without tripping the breaker mid-service.
