Comparison of different waterproof levels of waterproof power supplies

Different waterproof ratings have significant differences in protecting electronic devices from water damage. For example, a power bank with an IP67 waterproof rating can withstand immersion in 1 meter deep water for 30 minutes, while a power bank with an IP68 waterproof rating can withstand immersion in 1.5 meters deep water for 30 minutes. Therefore, when choosing a waterproof power bank, you need to choose the appropriate waterproof rating based on the specific use environment and usage requirements.
