    so far so good. i guess i didn't read through the description well enough to see the low amp charge. i have not noticed how long it takes to charge stuff, but its great to have when not close to an outlet or other power source. I bought it cause wanted a slim portable but find it is a bit heavy and max 20,000mAh. it works as expected and can charge both a phone and tablet at the same time. great for when the power goes out! and has multiple ports is has usb c for fast charging

    I bought two of the portable charger so my son would have one. I really like mine as it really is helpful when the electricity goes out. Also, my son has a IPhone12 Pro and the battery works with that phone.

    Nice texture, sleek accessory with quite a bit of juice for its size. 2 ways to connect it for recharging and 2 outputs make this a cut above most of the others.

    Got this for just over $50. Totally worth it. If you really need a wireless charging option to pay a little more and get the one with wireless charger.

    For how much I travel I'm upset I didn't get one sooner. Was literally on a plane for 24 hours, used my phone the entire time. This battery made it possible with plenty of juice left over.

    The battery life on this thing lasts for so many charges of my phone. I love that i can charge it using micro-usb or usb-c, so i can use whatever chord i have on hand.
