Many appreciate its compatibility with various devices and the reasonable price, especially when purchased on sale.

    Really good charger! Got it in sale and was worth it. Gives my iPhone XS Max a full charge and still leaves enough power for almost half charge.

    I bought these for my mom, who has an iPhone 8 and couldn't be bothered to figure out what cable charges the power bank and which the phone, and this was one of the first products that I came across that had Lightning charging. Since I got these for her, she has kept 3 of them on a bit of a rotation, allowing her to always charge her phone (since she keeps her screen brightness perpetually up and on), and have been extremely easy for her to use.

    Charging your apple iphones,ipads and the powerbank itself with one lightning cable. that is more convenient. It is not a big battery though.
