NEST Camera Dies At The Beginning of a Guest Stay

[Matthew Perez]

So, I received my first guest in my property, and they are staying for 70 nights. The day they checked in, I get a notification from my Google Nest Camera that my battery is at 5%. Their stay just started yesterday, so it could die at any moment. How do I go about getting this NEST charged? I feel awkward asking my guest to charge it for me, since it may seem like i'm spying? At the same time, I don't want to be in the dark. Any recommendations?
