Power Bank Model
(1) We Suggest 15W/18W/20W/22.5W power bank,
You can use 5V/3A,12V/1.5A,9VI2A,9V12.2A,12V/1.67A,4.5V/5A,4.5V/5A,7.4V/3A
(2)Output Power (W)=Voltage (V)×Current (A).eg:22.5W=5V*4.5A
(3)The higher the output power of the power bank,the higher the heating temperature.The output power of power bank need to be more than 15W,but do not exceed 30W.
(4)If you want better heating effect,You can use a higher output power of the power bank.After testing, the heating effect of the 22.5W power bank is very good.
(5)If the output power of your power bank is less than 10W,the heating temperature will be very low or the voltage and current are too low to work.

How to Use:
1.Take out the USB cable from the inner pocket and connect to the portable battery.
2.Press the output switch of power bank to open the power bank.
3.Press hard the switch of the clothes for 3 seconds.The switch lights turns red ,after 4 minutes it will automatically change to blue or white light for medium temperature control .
(Note:If the red light flashing ,it is normal,indicates automatic heating)
4.If you want to adjust the temperature, you can short press the switch to select the heating level.The Red State is about 45℃,White State is about 35℃,Blue State is about 25℃.You can press switch to red state and keep for 5 minutes,it will heat up fast.
5.Press hard the switch of clothes for 3 seconds to turn off the switch and stop heating.
6.If you do not use it,please unplug the power bank.
Trouble shooting
(1)The switch may doesn't work if the output power of power bank is too small. you will encounter these situations.
1.When I connect the power bank, I can not open the switch.
2.When I turn on the switch ,but then the switch turn off soon. 
3.I bought multiple switches heated vest, but when I open multiple switches at the same time,the switches will turn off.
You need to change a power bank of higher output power. If you don‘t have a power bank of higher output power now ,you can plug the USB plug directly into the plug of your phone charger to test if the switch works well. 
(2)When I connected to the power bank,before I open the switch of clothes,the switch continue to flash, which is normal.Just pluck USB plug ,then reconnect to the power bank
