Q: I want to keep this in my car for emergencies. How long does it hold its charge?

Q: Can I use this to charge my Apple I-phone?
A: Yes, but you will need an iPhone charging cord, its comes only with a micro cord for Androids

A: No, I have never used it to charge a fit bit before, I use it for my phone, tablet, kindle, wireless headphones, almost everything else. Most Fitbit require a unique charger that is not usb based if it is it should allow you to charge it but if it requires a unique base that is not a type us or USB type C then it might not work on any charging brick.
A: It comes with a micro-USB cable. I usually charge it through my desktop computer's USB port. Once's it's fully charged, I plug it into the micro-USB port on my laptop to keep it charged. If you want to plug it into an outlet, you can also get a USB adapter plug for about 5 bucks at a convenience store.
