Attention before purchasing:

  2. Size (7.68 x 5.91 x 1.1 inches) and weight (2.55 pounds)

Tips:

  • Low shutdown current for USB & TYPE-C ports: 50mA
  • Low shutdown current for DC-OUT port: 100mA
  • High shutdown current for DC-OUT port: 5V / 8.4V / 9V / 12V >3A; 16V / 20V >4.7A
  • If the power bank shuts off after 1 minute, it's due to the current of your laptop being too high. Please don't use your laptop or close the screen of your laptop, then charging it with the power bank.

How to Check Whether My Laptop Will Cause Power Bank Overcurrent or not? Please Check the label pasted on the adapter. If the output is more than 4.7A, it may cause overcurrent. So we don't suggest to use this power bank to charge your laptop.

Portable Power Station for indoor and outdoor use The compact and lightweight potable laptop charger is featured with one DC output, one TYPE-C output and two QC3.0 USB outputs. It provides off-grid power backup for emergency power failure while engaged in outdoor working and outdoor exploring life. We work and play on on our laptop and take laptop on camping or travel. No one wants to be caught out there with no power, this is why a good portable laptop power bank is critical and useful.

Adjustable DC output voltage The DC-OUT port supports 5V/8.4V/9V/12V/16V/20V and can directly charge your laptop without needing your laptop charger. Before charging your laptop or other device from the DC port, please double-click the power button to set the DC voltage.
