As one of the indispensable electronic devices in modern life, the importance of waterproof performance of power bank is self-evident. In outdoor activities, travel, bad weather and other environments, the waterproof performance of the power bank can effectively protect its internal circuits and batteries to avoid damage and safety hazards caused by moisture ingress. Therefore, when choosing a power bank, knowing its waterproof performance is an essential step.
First of all, we need to understand the relevant standards for the waterproof performance of the power bank. At present, the waterproof performance of the mobile power supply is usually evaluated by the IP rating, in which the second digit in the IPXX represents the waterproof level, and the higher the number, the better the waterproof performance. For example, IPX7 means that this power bank can be immersed in water at a depth of 1 meter for 30 minutes without damage. Therefore, when buying a power bank, we can pay attention to its IP rating and choose a product with a higher waterproof rating to improve its waterproof performance.
Secondly, the realization of the waterproof performance of the power bank is also the focus of our attention. Generally speaking, the realization of the waterproof performance of the power bank mainly depends on the housing material and sealing design. The shell material should be waterproof, moisture-proof, dust-proof, etc., and at the same time have sufficient strength and durability to ensure that it is not easily damaged in harsh environments. Sealing design means that each interface, button and other parts of the mobile power supply should have good sealing performance to avoid moisture from invading the internal circuit and battery through these parts.
However, relying solely on the housing material and sealing design is not enough to guarantee the waterproof performance of the power bank. In practical use, we also need to pay attention to the following points:
1.Avoid prolonged immersion in water. Although a power bank has a high water resistance rating, prolonged immersion in water may still cause damage to its internal circuitry and battery. Therefore, in outdoor activities, we should try to avoid leaving the power bank in water for a long time, especially when the water is turbulent or the water depth exceeds the waterproof rating of the power bank.
2.Avoid use in humid environments. Using a power bank in a humid environment may cause its internal circuitry and battery to be short-circuited or damaged. Therefore, in a humid environment, we should try to avoid using a power bank, or make sure its surface is dry before use.
3.Do not attempt to open the power bank case. The case of the power bank is carefully designed and manufactured with good waterproof performance. If we open the case at will, we may destroy its sealing properties, causing moisture to penetrate the internal circuitry and battery. Therefore, when using a power bank, we should avoid trying to open its case.
In addition to the above points, we should also pay attention to the care and maintenance of the power bank. For example, clean the surface of the power bank regularly to avoid dust and dirt affecting its waterproof performance; Avoid exposing the power bank to high or low temperatures, so as not to affect its performance and lifespan; Avoid keeping the power bank with sharp objects to avoid scratching its case, etc.
