    Mophies are great for keeping your devices charged, especially when you're away for electrical outlets. I brought these for my grandkids so on long road trips, there's no fighting over who uses the car charger to charge their multiple electronic devices.

    I bought 2 of these for Christmas presents because they really are nice, compact, work, and were on sale. The people they are for go to NASCAR all the time and like taking pictures with their phones and always run out the battery. Problem solved!!!

    I bought the Mophie before I went on a trip to California knowing that I would need extra power for my phone while taking a lot of photos. Made good use of it since I was on the go all day. The size is small enough that it can fit in almost any bag.

    I already had a power bank, but it always died real fast, so when it came for me to purchase another one this one seem like a no brainer. Last longer than my old one and I'm able to put it in my pocket without t bothering me.
