    I bought this charger because I play a lot of pokemon go, and one of the main issues with this game is how much it eats your phone's battery life. I participated in a 12 hour event and this charger kept my phone going the whole time, and left me with an extra 35% by the end. Definitely worth getting if you need a lot of power on the go!

    I love this portable charger. Has a good build quality and two USB ports, so I can charge multiple devices as well. Compared to my last portable charger, this one has lasted longer. The only problem that I have with the product is that the pouch that comes with it is kind of small. Another thing is that the texture feels weird to the touch.

    This is my second Anker battery pack. My only issue is I thought the USB-C plug was to charge my devices, but that plug only charges the battery oack. Bit if a disappointment that they have not updated the pack to charge newer devices that are all USB-C plugs and still uses USB-A plugs to charge.
