The power bank stores power through the built-in lithium battery, and then transfers the power to the phone through the output interface. When the mobile phone is connected to the charging bank, the charging bank will automatically sense the battery power of the mobile phone, and automatically adjust the output voltage and current according to the battery situation of the mobile phone, and charge the mobile phone at the fastest speed.
At the same time, the charging treasure will also provide fast and intelligent charging services for charging devices according to different charging protocols, such as QC and PD. Therefore, simply connect the mobile phone to the output interface of the charging bank to achieve convenient mobile phone charging.
Whether it is a charging bank or a mobile phone, there must be a wireless coil, as long as it can be sensed, and then charge the mobile phone.
