Power Inverters FAQs

Should the unit beep when I turn it on?
All CyberPower power inverters will beep when they are turned on or restarted.

Why does my device beep twice periodically?
This is due to overloading or underpowering.  Overloading is caused by an excessive load and can be resolved by either upgrading to larger power inverter, or reducing the load of the attached equipment.  If the device is underpowered, connect it to power source that is outputting greater than 11 volts.  Most often, users simply need to start their vehicle and recharge the battery.

Why does my unit emit a long solid beep or a series of rapid beeps?
This is due to overloading the unit. You will need to reduce the load placed on the unit or purchase a larger unit.

I am having problems getting the device to work on airplanes.  How can I resolve this issue?
Many airlines limit in-seat power to a maximum of 75 watts (most laptops require >100 watts). The recommended workaround is to remove the battery from the laptop so battery charging will not occur concurrent with usage.  This should reduce the power demands of the laptop to under 75 watts.
