It came charged already and I used it once at home to charge my cell phone just to check it out. I can't really tell how fast because I had to use my phone. Then I charged the charger to the wall and didn't finish charging because we had to go out. I bought this for our coming long road trip next month and it has the best price. So far, I like it.

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.

Haven’t used it yet but I like the direct plug and the built in usb c wire. It’s quite heavy and may be a problem for traveling with its size and built in plug
