What I’m holding in my hand is the world’s thinnest power bank, or some of you might call a USB charger. Measuring just 4.5mm think and weighing 75g … it’s small and thin enough to be placed inside your wallet. It comes with a battery level LED indiator and has a charging capacity of 2000mAh, which is enough to charge most smartphones including the iPhone and Android devices.

The middle photo shows a “Wifi” power bank … I’m guessing it allows you to charge it via a LAN cable or maybe not.
