TOZO PB1 PD Portable Charger 20000mAh Capacity Fast Charging Power Bank 18W High Charging Speed External Battery Pack with USB-C Input/Output Compatible - Gray

Full disclosure, I received these free from Tozo as a good customer, and in return I promised to write an honest review. I love this thing. I have the 10K mAh version also, and I thought its charge capacity was huge, so having twice the capacity is awesome! The multiple usb ports is great! It allows to charge multiple devices, while charging the battery itself if needed. It does take a while to fully charge the PB1 battery fully, but you can charge it for a little while, and it will still have a good amount of juice to charge devices. But the battery lasts a very long time, and the LED lights are very nice for providing a quick look at how much charge is left in order to make sure it doesn't get too low. The 20K mAh version is twice as thick as the 10, and about twice the weight. It's really convenient and reliable. I don't take it out of my home much, but when I do, I know I don't have to worry about my devices going dead. I find myself using it in home a lot because it can be more convenient than a wall plug and grabbing the right wire.
