What is the waterproof performance of the AV stick (actual measurement of underwater use)

　　Waterproof performance is very important for AV sticks. It is not only related to the service life of the product, but also related to safety issues during use. If the waterproof performance is poor, it may cause damage to the internal circuit and even cause a safety accident. Next, let us uncover the mystery of the waterproof performance of the AV stick through actual measurements.

test preparation

　　Select test products: We selected 5 AV sticks of different brands and different prices on the market for testing, with the price range ranging from 200 yuan to 1,000 yuan. These products cover a variety of types and designs to ensure representative test results.

　　Prepare the test environment: A special test tank was built to simulate different underwater environments, including shallow water areas and deep water areas. At the same time, professional testing equipment has been prepared to detect the performance changes of AV rods underwater.

Shallow water testing

　　Test method: Place the AV stick into shallow water with a depth of about 10 cm, turn on the power, and observe its operation underwater. Continue the test for 30 minutes and record whether there are any problems such as water leakage and abnormal functions.

　　Test results: In shallow water testing, most AV sticks performed well. Among them, 3 products with prices above 500 yuan are stable in operation, have no water leakage, and all functions are normal. Among the two lower-priced products, one had a slight leak during the test, causing some functions to malfunction.

Deep water testing

　　Test method: Place the AV stick into a deep water area with a depth of about 50 cm, also turn on the power, and conduct a 60-minute test. During the testing process, closely observe changes in the appearance and performance of the product.

　　Test results: In the deep water test, the difference in waterproof performance is more obvious. The three products with higher prices still perform well and can withstand greater water pressure and operate normally. The two lower-priced products both had water leakage problems to varying degrees, and one of them was even completely damaged and could no longer be used.

comprehensive analysis

　　The relationship between price and waterproof performance: It can be seen from the test results that, generally speaking, higher-priced AV sticks perform better in terms of waterproof performance. This is because these products typically feature higher quality materials and more advanced waterproofing technology.

　　Suggestions for use: If you plan to use the AV stick underwater, it is recommended to choose a product with a price of more than 500 yuan to ensure waterproof performance and safe use. At the same time, read the product manual carefully before use and operate it in the correct way.
