3C certified (Safe for China travel) portable small form charger (5000maH)
I bought the portable charger for 2 reasons. 1. Its certified for travel in China (CCC certification). 2. Its portable form factor (fit into my pocket).
Besides this it also has a built in USB C cable for charging and also a replaceable apple lightning cable head and a usb-c cable head. Given i have an iphone 11 but i carry an android tablet, this is a huge convenience.
