    It’s ok not great but ok. It charges great but since the plug is a flip out if you have it in your pocket it will move back and forth. Never had any problems of it disconnecting and charged really fast as ankers do.os a great charger as long as it’s not moving around.

    Bought this product for my wife after she was complaining about not having a portable power bank. She has been very happy with this product and doesn't leave without it. Charges really fast and is very small and compact. Thinking about buying one for myself.

    Gets the job done. It is a little hard to operate my phone when it is attached to the bottom. Besides that it is great. Very portable and good for having as a backup.

    Super convenient! I bought this when I was in a pinch at work and it has come with me everywhere since! It fits perfectly in a bag or pocket and makes it easy to still use your phone while it's charging it.

    This product charged my Pixel fold really quick. It was on 1% and I left it alone for 10 minutes and it was at 86%. This in my opinion is a really good charger especially if you're traveling or just want a portable to fit in your pocket or purse

    The power bank's compact dimensions render it highly portable. While the charging speed is moderate, it is well-suited for maintaining your phone's operational status during on-the-go use. It is important to note that this device is not designed for rapid charging, and optimal functionality cannot be achieved when the power bank is connected. This design is particularly advantageous for flip phone users, as it eliminates the need to hold the phone while charging.

    Charges phones quickly and up to 100%. The battery itself charges in a decent amount of time. Much better than having the versions with wire so directly attaching to the phone is a huge plus. Would purchase again.
