Does the DEWALT DCB1800 Power Station draw idle power while on, but not being used? How long will the batteries last under idle condition?

 
If Portable Power Station is turned on, but not being used, it will draw a small amount of battery power.

How long the batteries lasts depends what batteries are installed, but a set of fully charged batteries should last at least several hours at idle power.

We recommend turning off Portable Power Station if it will not be used within half an hour.
