Home with 2 millet jack board, 19 years to buy, to now use more than 2 years, basically no problem, or good to use. Should also support fast charging, faster than the general usb charging! A long one with 3 usb ports and a square one with 3 usb ports. You can charge 3 devices at the same time, and occasionally get hot in the summer, it is generally very good to use.
