How to quickly distinguish a good pump from a bad one?

2024-09-07

Duration of use

The duration of use can also be called the service life of the product. It indicates how many times the pump can be used to inflate tires. Although the pump may be used rarely as an emergency device, a normal quality product should withstand at least 50-100 cycles of use. Some very cheap models on the market usually cannot reach this level, and their service life is significantly shorter.

 

 

Current stability

It is important to check whether the current is stable when the pump is running. Since there are current and voltage issues during operation, the car pump usually uses 12V power from the car, and the operating current should be less than 10 amps. If the current is unstable or exceeds 10A when the pump is running, it may cause the car fuse to blow, and in the worst case, it may damage the car's electrical system, which is very bad for the owner. This problem usually occurs in cheap and low-quality products.

 

 

Inflation speed

The quality of the pump can be determined by the inflation time. For example, for a standard 195 tire, a regular pump on the market inflates it in 3-10 minutes. Small pumps have an inflation speed of about 7-10 minutes, regular pumps - 4-6 minutes, and high-pressure direct-drive pumps can inflate a tire in less than 4 minutes. A regular pump that works within 4-6 minutes is enough to inflate passenger car tires. If a regular pump inflates a tire in 10 minutes or more, it can be considered a low-quality product. Direct-drive pumps are more often used to inflate truck tires and other large vehicles.

 

 

Product Materials

To assess the quality of the materials the pump is made of, you can simply smell it. If the product is made of primary materials, the smell of plastic will be barely noticeable and not sharp. Such products are, firstly, more durable, and secondly, safe for health. However, if the product emits a strong unpleasant smell, this may indicate the use of recycled materials. Such products are usually less reliable and may contain toxic substances. Therefore, smell is an important criterion when choosing a quality product.
