    That puppy can charge my Note 9 up to 3 times! Little bit bulky, but you don't have to worry about running out of juice.

    Has plenty of juice for the price point. If I were to buy a different pack, I would probably spend a little extra. Slow recharge on the unit itself and the lightning charging port isn't much faster then the regular charging port with my Galaxy note 8.
