5. Oceanwide micro is equipped with two-stage toggle switches on and off, which can be charged normally no matter whether the switch is on or off; When the switch is on and the power key is touched, it can work normally, and the speed regulation can be realized by increasing and decreasing gears;
6. There are two groups of nixie tube displays on the panel. The left side displays the speed gear (00 ~ 30), and the right side displays the power (01 ~ 99). The increment and decrement of nixie tube are in 1;
7. When charging, the left nixie tube displays the charging status (similar to a running lamp), and the right shows the real-time charging power. The battery is full
