    Already have the 10K charger which is great. Needed something a little easier to fit in pocket with the iPhone.

    Helps an older phone stay charged

    I have my brother this for his birthday. He has an older iPhone which the battery doesn’t hold a charge as well. He loves having the security of charging without cables. My family members have purchased more than 20 items and have never been disappointed. Try it you will like it. He loves this one for the lack of thickness.

    This is perfect

    I’m loving the Champ 5k. I was able to retire much heavier and bulkier backup batteries.
