TZS 40L lockable mini fridge: what works, what doesn't?

What works well

  • 22 dB silent: The compressor-free cooling system runs vibration-free and is therefore ideal for bedrooms, offices and hotels too
  • Lockable: Lock and two supplied keys secure the contents, handy in hotels, shared flats or shared offices
  • Reversible door hinge: The hinge can be mounted on either side to suit the room, so the door opens left or right
  • Adjustable cooling: The adjustable cooling output keeps the temperature constant and can be matched to need
  • Light & flexible: At only 12.3 kg the minibar is easy to transport and versatile at home, in the office or while camping

Points of criticism

  • High price: Around €210 is well above no-name 40 L appliances, the premium pays for brand, lock and build quality
  • No dB advantage without a compressor alternative: Like all thermoelectric units it only cools relative to room temperature; the manufacturer gives no concrete minimum temperatures
  • No freezer compartment: As a thermoelectric minibar it offers no freezing function, unsuitable for frozen food

Build quality & everyday use

What carries the TZS 40L lockable mini fridge in everyday use: 22 dB silent (the compressor-free cooling system runs vibration-free and is therefore ideal for bedrooms, offices and hotels too) and lockable (lock and two supplied keys secure the contents, handy in hotels, shared flats or shared offices). We have to be honest about the weaknesses: high price (around €210 is well above no-name 40 L appliances, the premium pays for brand, lock and build quality).

If you set the device up to save space, allow ventilation clearance of at least 5 cm at the sides and 10 cm at the rear, otherwise the compressor may overheat.

“TZS First Austria mini fridge 40L: 22 dB silent and lockable, and the trade-off is high price. At 8.5/10 a safe choice from €210.”
