Thank you Mary. I am John and I am going to talk about the third point, At now, every electrical appliances need the plug that it can be use. But not everywhere will have a wall socket to use. Based on this inconvenience, our product has added this new feature. The induction cooker does not need a plug, as long as the battery is sufficient. And the battery is dead, you can continue to use it with mobile charging. USB is the most common charging method in this era. People with mobile phones basically take mobile batteries to go out. So combining the induction cooker with a USB plug is the best way to cooperate with this generation.
