You can buy YONGNUO external charging boxes like SF-18C or SF-17C and connect it to the charging port of the speedlite.
After flash, the charging box will charge the speedlite.
9. High-speed continuous shooting
10. Reflection Flash
Bounce flash means to take photos by making flash light head
aimed at wall or ceiling and using the light reflected back from
the ceiling or wall to light the desired object, so that the shade
behind the object can be decreased to get more natural
shooting effect.
If the wall or ceiling is too far, the bounce flash may be too
weak to get enough exposure. The wall or ceiling should be
even and white in order to get efficient reflection; if the
reflection surface is not white, color cast may appear in photo.
