How Can You Make Use Of The USB

You may wonder at first what other functions a USB has except for charging. For some vapes, it is true that the USB can only be used to charge the device. However, it is not true of the Eleaf iStick QC 200W which uses the small USB in several ways!

Besides the function I've mentioned above, the USB can also be used for firmware upgrading just by connecting the device with a computer through the USB port via a micro USB cable. Another function is to use the USB to charge other electronics thus turning the Eleaf iStick QC 200W into a power bank.

Such a small USB of the iStick QC 200W  has ao many functions! Are you impressed by it!
