When choosing a waterproof power supply, you need to consider the following factors:

Waterproof level. Different waterproof power supplies have different waterproof levels, generally divided into IPX4, IPX5, IPX6, IPX7 and IPX8. IPX4 can prevent water droplets from splashing, while IPX8 can be used underwater at a depth of up to 3 meters. Therefore, when purchasing a waterproof power supply, you need to choose a suitable waterproof level according to actual needs.

Battery capacity. The battery capacity determines the power that the waterproof power supply can provide to the electronic device. Generally, the larger the battery capacity, the longer the use time. You need to choose according to actual needs when purchasing.

Charging method. Most waterproof power banks support USB charging, but some products require the use of specific chargers or charging methods, so you need to understand clearly before purchasing.

Additional functions. Some high-end waterproof power banks also have other functions, such as flashlights, SOS rescue functions, etc., which can provide more convenience for outdoor activities.

In general, waterproof power banks are a very practical electronic accessory in outdoor activities, but you also need to pay attention to care and maintenance during use. Waterproof power banks are prone to water ingress at the interface, so they need to be cleaned and dried in time after use to avoid problems such as circuit short circuits.

The name of the waterproof power bank has told us that it is waterproof, but do we really understand what protection it provides for our mobile phones?

First of all, as mentioned at the beginning of the article, the waterproof power bank can provide reliable power support for our mobile phones. During outdoor activities, if the battery of the mobile phone runs out, it is easy to cause communication failure or get lost, etc. Waterproof power bank can help us solve this problem.

Secondly, in some water activities, such as kayaking and rafting, the mobile phone is easily wetted by water or even falls into the water. If you use a waterproof power bank, even if the mobile phone falls into the water, it can continue to work.

However, waterproof power banks cannot completely protect mobile phones from water damage. In various water activities, the time and circumstances of mobile phones entering the water are very complicated. Sometimes, even with the use of waterproof power banks, electronic devices may still be damaged by water. Therefore, when using waterproof power banks, other waterproof measures are also required, such as waterproof mobile phone bags, waterproof mobile phone cases, etc.

In general, waterproof power bank is a must for outdoor activities. It can provide reliable power support for our mobile phones and protect our mobile phones to a certain extent. However, it should be noted that in water activities, a variety of waterproof measures need to be adopted to better protect our electronic devices.
