Tips:

We recommend that the solar panel output voltage is between 15-25V and the output power is less than 80W.

Low shutdown current for 5V port: 70mA

Low cut-off current for 12V port: 150mA

Low cut-off current for 20V connection: 200mA

High cut-off current for 20V connection: > 4.5A

If your laptop turns off automatically for a few seconds or minutes, it may be caused by over-current/low-current protection.

If the auto power off is caused by over-current protection, please close your laptop screen or fully charge your laptop and then charge the laptop with our power bank. If you're trying to power a Windows laptop and the battery keeps disconnecting, you may need to change the power settings, pre-change the power settings, select the "Turn off hard drive after" setting, and set the option to NEVER and in power options DISABLE "Intel Cppc Energy Saving"

How do I know K2 Solar can charge my laptop?

Please check the label on your laptop's adapter. If it is more than 95W (DC output current is more than 5A), the power bank may shut down due to overcurrent during charging. For this reason, we do not recommend using our power bank to charge your laptop.
