Eight functions: 185h battery life, waterproof design, auto-start after power failure, intermittent mode, charging separation, A1 chip, 185H ultra-long battery life: 6000mah lithium-ion polymer battery, 6600mAh enough capacity, using high-quality lithium polymer batteries, power outages go out fishing 120H, can also meet the needs Core protection: multi-process waterproof design, built-in adhesive strip, multi-process waterproof design, built-in adhesive strip About waterproof: 01: The oxygen pump that accidentally enters the water will not give out oxygen after a period of time, which is related to the working principle of the oxygen pump. Take it out of the water and wait for a while to use it normally. 02: The oxygen pump that accidentally enters the water will enter the water body. After removing the water, it is recommended to set up to empty the water to avoid rusting caused by moisture inside for a long time. Bass experience: 1. ABS noise reduction shell 5mm thickened to
