    The battery is small and easily to transport with you even though it’s a little heavy. It has very good performance and quality for the price. The product is good and charges my iphone 13 pro. The only complaint that I have is that it charges very slow.

    Great power bank! Love the screen that shows how much power is left. It's pretty hefty/bulky so may not be for you if you need to put it into a small purse or bag. Overall, very satisfied and meets my needs.

    Percent of charge is displayed, which is very helpful. However the cable attached to the charger doesn’t meet my needs and seems superfluous.

    I think it's too heavy to travel with in your carry on and I don't find that the battery lasts long when you're using it. The built in cable is useless you still need to bring a lightening bolt if that's what your iphone uses. Also, when you'e not using it, the cable is just always hanging out, it doesn't tuck away anywhere. t;s sat in a drawer since I bought it. Waste of money to me.

    No, I would not recommend this to a friend
