Which portable power bank is better for iPhone 5?

Since my phone always dies when I'm out, I decided to look for a portable power bank on online. Just wondering which one is better, 5600mah or 2600mah? Need a quick response.

5600mah because it charges faster and it is better on the battery… When you use a trickle charger (anything below 3000 mah) then it can gradually drain the battery because it doesn't have an automatic power shutoff so it is literally overfilling the battery with unnecessary energy that can discharge at a moments notice.

5600mah portable power bank is better for iPhone 5. However, if you need to buy portable power bank you can visit this site http://www.jlwpower.com/power_bank/

  • Power bank turns off when charging iPhone? Within a few seconds of plugging my iPhone in, the lights on the power bank turn off, and my iPhone stops charging. Could this be a defective cord? Or is it the power bank/ my iPhone? Please help, it's making charging my phone almost impossible because it won't charge through an outlet. Only my power bank.

  • 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?
