3. Electrical protection requirements
3.1 Short circuit protection
When the output is short-circuited, the input power of the product will be reduced and will not
be damaged. When the short-circuit condition is removed, the product will not be damaged.
3.2 Input overvoltage protection
When the input voltage far exceeds the rated voltage value of the product, the product is
protected without damaging the equipment.
3.3 Battery protection
When the battery is overcharged, overdischarged, reversed or short-circuited, the battery
will not be damaged and the product will not be damaged.
3.4 Unprotect
When the product is in a protected state due to improper use, recharge the product to
release the protection.
4. Working environment
4.1 Operating temperature:：0°C ~ 40°C (32°F ~ 104°F)
4.2 Storage temperature: -25°C - 45°C (-13°F - 113°F)
4.3 Relative humidity:Non-condensing state 0% ~ 90%
5. Function instructions
5.1 External power charging
Use a charger with a rated output voltage of 5V and an output current greater than or
equal to 1000mA to charge the battery of the product through the Micro 5P cable. At this time,
the battery indicator of the product will flash to indicate the charge status (25%, 50%, 75%,
100%) 4 When charging, the flashing prompt will be based on the battery level to which it is
