    I have had this battery charger for over two years and a half and it still works great. I can charge my phone 2-3 times before having to charge the Anker again.

    I got a couple of these for when my family goes on vacation. These worked great as I'm usually the one carrying the battery packs and extras, and having the slim design meant a much smaller pack I had to carry. They kept a solid charge for the entire day even when charging up 4 smartphones, and at least 3 sets of wireless earbuds.

    This is a great value for what it is. It does not charge from the usb c port, only the usb a ports. The usb c port is only for charging the powerbank. The powerbank takes a long time to fully charge up and it does not charge devices incredibly fast. However, it is fast enough for my purposes. It does hold a lot of power and fits easily in a bag or pocket.

    I just purchased this charger and used it for the 1st time. So far it works fine. I don't need it all the time but I will use it those times when I have to go to the hospital or when I away from my main charger. It is fairly light and fits perfectly in.my go away bag and in my small purse.

    Holds a charge for ages, I use mine to charge my Fitbit and I can use it for weeks before needing to charge it again. When I've used this battery for larger items like my cellphone, I get at least 2 full charges, sometimes more. It charges fast and doesn't overcharge. 10/10

    The device itself charges fast thanks to the usb-c, but that’s only for input. output is only from the usb-a ports so make sure the device you want to charge has a usb-a connecter. I’ve had one for over a year and it’s been consistent with time to charge itself and portable devices

    Always a balance between the weight and capacity of a power pack. This has 2 full recharges of my iPhone and is not too heavy. Even in an airport terminal, plug in the power pack to an electric plug and charge it and use the phone simultaneously.

    It's large but portable to carry around still. I have a Pixel Fold where the battery life isn't that great, and this is more then capable of charging it and then some.

    I like that this one is small enough to carry around in a pocket and not too heavy. I get about four charges with it using my iPhone. Sometimes I have to press the power button to start charging devices, but otherwise, so far, so good.
