The DC power jack in black is for connecting those power adapters with
5.5mm/2.1mm plug. Many power adapters for notebook belongs to this category.
Different than the micro-USB and then terminal block, the connection between barrel
shaped plug and DC power jack is not that tight, as it could still be rotated after the
connection. This might lead to unstable input voltage, which should be avoided.
If Zero2Go is used on a portable project, it is recommended to use the micro-USB or
terminal block for power source connection. If the DC power jack is used, it is
recommended to take additional efforts to fix the barrel shaped plug on its place.
Please keep in mind that, the power source should have very solid connection to
Zero2Go. If you are using the terminal block, please make sure the wires are tightly
fixed, and they should not be disconnected during the usage. If the connection is not
reliable, it could lead to very bad consequence, especially when input voltage is
higher than 20V. In worse case it could burn out the MOSFET on Zero2Go and then
kill your Raspberry Pi!
Caution:
please
avoid poor contact between power source and Zero2Go.
Caution:
quickly connect and disconnect power source is a big
