40000mAh Notebook Power Bank 3.5A 19V DC 2 USB External Battery Charger for Laptops Notebooks Tablets iPhone X 8 8 Plus

 

 

 

  • 1. Main parameters
  • Using six IPAD lithium batteries with a nominal voltage of 11.4V and a nominal capacity of 8200mAh
  • 12-bit intelligent MCU, imported lithium battery protection IC, high efficiency DC module
  • Output voltage: 5V, 12V, 16V, 19V
  • Output current: 5V 2.3A, 16V, 19V 3.5A, 12V 4A
  • Output efficiency: 5V maximum efficiency 90%, maximum current output efficiency is not less than 86%; 12V and 16V, 19V maximum efficiency 94.6%; maximum current output efficiency is not less than 92%
  • Output ripple: no more than 100 millivolts at full load output.
  • Shutdown current: less than 230 microamps
  • Size: 115mm*195mm*21mm
  • 2. Function description

 

 

  • When the MCU detects the insertion of the adapter, it automatically turns on the machine and enters the charging state. At the same time, it displays the battery information. When the battery is fully charged, it automatically stops charging and prompts the charging to be completed. A special DC adapter must be used to avoid the machine safety accident.
  • 2. Discharge function:
  • In the power-on state, the USB socket can be inserted to obtain 5V output, and the standard 5.5DC socket can obtain 12, 16V, 19V three-select voltage output, and the output voltage reference follows the operation convention.
  • 3. Display mode
  • Four blue LEDs to display battery power and four red LEDs to display output voltage
  • Operational convention
  • Short press the button to boot, the system will silently input 5V and 12V after booting.
  • 1. In the power-on state, short press the button to select the output voltage, which is 12V, 16V, 19V in turn, and light the corresponding indicator LED
  • 2. In the power-on state, 12V, 16V, 19V output is inserted into the load, long press (more than three seconds) button, the machine enters the automatic recognition mode, the machine automatically finds and outputs the adaptation voltage of the inserted load, which may not be available for some models. Identification
  • Five. Standby mode
  • In the power-on state, if the load is not inserted or the load is fully charged, it will automatically shut down after one minute.
