Portable Power Bank by Merkury?

I have this Portable Power bank to charge my iPhone: http://www.merkuryinnovations.com/portable-power-bank-2000-mah/
I plan on taking it to a trip to Canada next week because I won't always have access to a wall port to charge my phone. I'm wondering, though, how long the charge in the power bank will last? For instance, if I charge the port overnight on Tuesday and I'm leaving Friday morning, will the power bank still be fully charged and be able to charge my phone?

They stay charged until you plug your phone into them. And you should be able to keep them charged from the vehicle cig lighter outlet.

Your Power Bank is 2000 may, so hopefully your battery in the phone is less than that so it will fully charge at least 2 times during your trip.
