    It's the perfect size and not as heavy as i expected. I like that it has charging lights to show you where you are in charging and it has a check button that will show you how much energy it still has. I love that it has two different ports. Recharges fast and lasts long enough for me.

    I got two of these portable chargers because my phone had almost died while I was shopping with my little brother. Its amazing how slim and how fast it charges. They will definitely come in handy. My old one is small but chunky but these are better to carry.

    Exactly what I needed and can’t beat the price. Lasts a 10 hour work day with my older iPhone 8’s bad battery. It’s the size of my phone and super lightweight.

    This is perfect for travel or everyday use. Takes about 2 and a half hours or so to completely charge. It can be charged with a micro usb or usb C cable. I have used it to charge iPhones, watch and iPad. Plenty of charge for my devices. I have taken it on a few trips and it works well and fast. Feels heavy which I like and a bit warm when charging. It also charges while charging. Although this is not mentioned in the instructions booklet it’s probably not a good idea to do. If your going to charge your devices while charging the power bank be sure to stay close to it just in case.

    Gonna say I appreciate how much power can be stored on this for use on recharging my iPhone (even if it takes awhile), and for the price I paid it is very much worth it. The ONLY thing that I find a bit of an issue, and is preventing me from rating it a full 5 stars is that the lights that indicate how much power is stored stopped working properly less than a week of usage. Now only 1 light of 4 lights up all the way, so I have to always guess how much power I've gotten left to use for my phone. Other than this...it DOES work. Just wish the bulb wasn't so faulty, and I don't know why it is this way.
