In the run-up to the test, we defined practical requirements and the following test criteria:
- Wearing comfort
- Laptop security
In order to evaluate these criteria, we have defined several tests for laptop backpacks. First, all compartments are checked for size and function. The backpacks are filled with 2, 5 and 8 kg in order to assess the wearing comfort at different weights. It is also checked whether the backpacks are stable when empty or fully loaded. The robustness of the backpacks is then tested. The rucksacks are then sanded over asphalt and the effect assessed. The backpacks are also tested for water resistance. Especially the density of the zippers is tested.
In further test runs, it is checked which laptop sizes fit into the backpacks. In addition, it is tested how safe the laptops in the backpack are from external influences and whether the material in the backpack protects the laptops. Finally, it will be tested to what extent the backpacks can be used for other purposes, e.g. shopping. The insulation of backpacks with cooling compartments is tested. For this purpose, a cooled bottle of water is stored in the cooling compartment and the temperature is measured after one hour.
In order to rule out errors and to ensure the stress of everyday use, each test takes place in several rounds.
The test criteria are given percentages depending on their importance. The final score is then objectively calculated from the test criteria using an algorithm.
Our product selection is based on an observation of the current market. In addition to popular branded products, we also include insider tips in our selection. Criteria such as price and range of functions are an important factor for us. The test field is also determined by analysis and evaluation of customer reviews and external tests (e.g. Stiftung Warentest).
The devices are purchased anonymously or lent to us by the manufacturer. Dealers and manufacturers have no influence on the tests and our evaluation.
As soon as new relevant products come onto the market, our test field is extended by these. The new products go through the same test as the already tested devices.
