Product Description

Pay Attention:

2.Can not charge Laptops with USB-C input port such as Apple Laptops(we suggest buy our B017QUHB44 for Mac Laptops)

3.Support 2 Recharge Way: AC Wallout/Car( but need to buy a DC to AC power inverter, we suggest to buy our B07PXHFTT4).

4.Compatible with 95% Laptops including Dell HP Lenovo Surface pro Sony Samsung Acer Toshiba iPad Phone Notebook

If your laptop turn off automatically for several seconds or minutes, it may caused by overcurrent/lowcurrent protection.

if automatic turn off is caused by overcurrent protection,Please close the screen of your laptop or fully charged your laptop first, and then use our power bank to charge the laptop.if you are trying to power a Windows laptop and the battery keeps disconnecting over and over, you might have to go into Power settings, Advance power settings, and find the setting for "Turn Harddrive off after" and set that to NEVER, and in power options DISABLER "Intel Cppc Energy Saving"

How Can i Know Whether My Laptop Will Cause Power Bank Overcurrent or not?

Please Check the label pasted on the adapter, if it is more than 130W (DC output current is more than 7A). it may cause our power bank turn off during charging for overcurrent. so we do not suggest to use our power bank to charge your laptop.
