    Powerful Bank

    This power bank is great. It has plenty of juice for multiple charges. It is a little bit heavy, but worth it for the power. I would recommend it if you want to be able to charge or phone and other devices multiple times before needing to recharge it.

    I’ve used this for over a week and have had many other portable chargers but being able to charge it directly into the wall without having to worry about more cables or charging bricks is extremely convenient. Love this charger and seems to charge quite well also. Highly recommend specially if it’s on sale.

    This is the best thing ever to keep my phone and other devices charged when I don't have access to an AC outlet. I carried this on the plane during a recent trip and was able to keep my phone charged and it's the same size as my phone, which makes it easy to carry around. I like that it has a connector that doesn't detach, meaning I can't lose it. The price was right as well. It plugs in and charges rapidly. I've used it for days on end without having to recharge. It has four status lights so you can tell how much charge is left.

    One of the best purchases/investments made in a while. I got my husband one and realized how helpful it has been to him. This charger is so helpful on the go and charges my phone quickly. I LOVE that you can just plug it into the outlet when it's time to charge it back up. It is a little bulky though...

    Much better and cheaper than the magsafe version. Charges as soon as you connect a device. Needs a usb port for older devices though. Large and heavy so it is won’t fit in a small purse or bag.

    I love this charger. I needed something small and portable to charge my devices while traveling, as sometimes, you are not able to find an available charging station at the airport. I also come in handy if you forget to charge your devices. The charge on it, last a long time. Only thing I wish is, that it can with 2 USB connections.

    So far so good about this for my son to use in the military. I love the onboard features and the fact that it has the plug and he only has to have one thing. The size is decent it's not too heavy and it has a high capacity for lots of recharging

    This worked perfectly. We bought this to use while on vacation. It worked wonderfully while we were out and about sight seeing keeping our phones charged. Only downside, is the size and the weight.

    This is my go-to battery backup. It is great at keeping my cell fully charged when I'm volunteering at the food pantry and also when I'm working my p/t job at the movie theaters.

    I brought this powerbank and it is great if you have a c charge phone. The only down side is you can not charge an Apple phone but other than that it was a GRAT buy for me!! A little on the heavy side.

    Feels slightly lighter than another 20,000mAh portable charger I own. So long as the attached cable continues to work, the extra features are super convenient. Only thing to note is it does not have a usb-a port for charging, only usb-c and the attached cable.
