  • 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?
