Tristar OV-3650: the cheap mini oven for singles & camping

Prices in euros from Amazon.de, as of 11 June 2026. Prices and availability may differ on Amazon.co.uk.

Not everyone needs fan convection, a rotisserie spit and a pizza stone; sometimes a mini oven should simply be cheap and bake things up reliably. That is exactly what the Tristar OV-3650 is: 20 litre cavity, top and bottom heat up to 230 °C, a 60-minute timer and a double-glazed door that keeps the housing cooler on the outside, for often only around 60 euros. For toast, bread rolls, frozen pizza or a small bake in a single household, a holiday flat or while camping, that is entirely enough. The budget pick in the comparison.

Tristar OV-3650: what works, what doesn't?

What works well

  • Cheapest in the comparison: Often around €60, the budget pick for a tight wallet
  • Double glass door: Keeps the casing cooler on the outside than simple models
  • Simple operation: Two dials, no frills, understood at once
  • Good for camping & holiday flats: Compact, light, works from any socket

Points of criticism

  • No fan: Top/bottom heat only, heats more slowly and somewhat less evenly
  • No interior lighting: Cooking can only be checked by opening
  • Coarse temperature scale: Thermostat deviates from the set value, bake by experience

Build quality & everyday use

What carries the Tristar OV-3650 in everyday use: cheapest in the comparison (often around €60, the budget pick for a tight wallet) and double glass door (keeps the casing cooler on the outside than simple models). We have to be honest about the weaknesses: no fan (top/bottom heat only, heats more slowly and somewhat less evenly).

If you set the device up to save space, make sure it stands on a stable, level surface with some air around it. This protects the mechanics and electronics in continuous use.

“Tristar OV-3650 mini oven 20 L: cheapest in the comparison and double glass door, and the trade-off is no fan. At 7.8/10 a fair deal from €60.”

Frequently asked questions about the Tristar OV-3650

What is a mini oven for under €60 worth?
A lot for the basic functions: the Tristar OV-3650 reliably bakes off toast, rolls, frozen pizza and small bakes with top/bottom heat up to 230 °C. You have to do without fan heat, interior lighting and an exact temperature scale, but for occasional use in a single household or while camping that is entirely sufficient.
Does a mini oven absolutely need fan heat?
No. Fan heat distributes the heat more evenly and is practical on several levels, but for single trays top/bottom heat as on the Tristar OV-3650 is quite enough. If you only bake off now and then, a top/bottom heat model saves money; if you bake often and in variety, a fan oven (e.g. Severin TO 2079) serves you better.
Is the Tristar OV-3650 good for camping or a holiday flat?
Yes, it is ideal for that: compact, light, cheap and runnable from any normal socket. If the mobile home or holiday flat has no oven, it brings the basic function at a small price, without worrying about the appliance.
Why does the Tristar OV-3650 have no interior lighting?
That is the typical saving point on very cheap mini ovens. You check cooking progress through the double-glazed door (best in daylight) or by briefly opening it. If you want interior lighting, you will find it on the somewhat more expensive models from about €97 (Severin TO 2079).
