    I really like this portable charger. It's slim and fits perfectly into my backpack for those days when I cannot stay around a socket. I took off a star, because mine doesn't seem to want to charge USB-C devices, despite having a USB-C port. Other than that, it works fine.

    I recently started a job where my phone gps stays in high demand amd with no inside car ports a battery pack is a must. For the short time ive had this .. i can honestly say im in love. It keeps up with my brightness of linking and high demand of phone use with ease and is able to still continue to charge while at full use. Nothing but good things to say

    Charges our phones at rocket speed. Feels sturdy and it’s bulk is no problem because we use it at home and on long trips (I.e. Africa). The only thing is that we’d rather have a gauge that tells what percentage of juice is left…the 4 lights make it a guessing game.

    Overall this is a very good portable charger. It has plenty of power to use as my backup, especially while travelling. My only concern is that it is much larger and heavier that I anticipated. I purchase this online and did not realize the size.
