If you own or plan on owning a USB-C powered device, this power bank will be an essential tool and an investment for your future devices, trust me on this. Can't find a wall outlet to charge your laptop? No problem, this charger can handle it. Phone's almost dead and you need to make an important call? No problem, the built in Power Delivery was able to get my phone from <10 - 50% in about 15 minutes. This is my second purchase because my car was broken into recently and the robber had stolen this battery and my equipment =(. But luckily, I was able to recover it all through insurance. I've also read that this thing can fast charge the latest iPhones with Apple's USB-C to Lightning cable, so I'm gonna give that a shot with on the wife's iPhone X.
