About Us

Prüfengel offers authentic consumer tests in which real users share their experiences with products. Our tests are based on practical applications in everyday life and reflect the opinions of consumers. As we focus on consumer tests, we do not carry out any material, long-term or laboratory tests. The tests are carried out by 1-2 independent consumers over a period of 7-14 days. The exact test conditions can be viewed in the test plan of the respective test report – click here to go directly to the test plan.

Manufacturers provide the tested products free of charge. We charge a one-off test fee for carrying out the tests. In addition, manufacturers pay an annual licence fee for the use of the Prüfengel seal. We also receive a commission for linking to manufacturers’ websites. These remunerations have no influence on our test results or ratings.

We guarantee transparency and a fair evaluation. For a detailed insight into our comprehensive evaluation process, please click here.

Soniq
Kooler

Manufacturer’s product description

The Soniq Kooler cooler is aimed at anyone who doesn’t want to go without fresh food and cool drinks when van life, camping, or on longer trips. In the test, the compressor cooler impressed with its powerful cooling performance, energy-efficient technology, and whisper-quiet operation.

A particularly positive feature is that the integrated battery monitor prevents the vehicle battery from discharging – a real plus for campers who want to camp self-sufficiently. In addition to fast cooling performance, the product also offers excellent energy efficiency and low noise levels.

However, app control or a digital temperature display would have been desirable to make operation even more convenient.

Overall, the Soniq Kooler cooler presents itself as a robust, durable, and powerful companion that works reliably even at high outside temperatures of up to 38 °C. It thus meets all the requirements of modern outdoor enthusiasts who value quality, performance, and mobility.

  • Strong cooling performance down to –20 °C
  • Very low power consumption
  • Whisper-quiet compressor technology
  • Robust construction and good stability
  • Easy handling thanks to sturdy handles
  • Weight could be borderline for some users

Upon opening the box, we noticed that unnecessary packaging waste had been deliberately avoided —an aspect that we rate very positively in terms of sustainability. All components were securely stowed and complete. During testing, the operating instructions proved to be clearly structured, easy to understand, and practical, allowing us to get started right away. Overall, the packaging made a professional, environmentally conscious, and customer-friendly impression, as you would expect from a modern brand like Soniq. This shows that, in addition to functionality, responsibility for the environment and user comfort are also a priority.
