S8's own battery cannot, must plug the fast charge power adapter.Saw it over at the pop up booth at Ngee Ann a couple of days back, it's pretty cool! reminds me of the good old days of the Motorola Atrix ..
Sadly, unavailable for my S7
Can it be self powered by the battery in lieu of connecting it to the socket?
It is ok with Samsung fast charge powerbank. But Third party powerbank (even with fast charge feature, eg. xiaomi) cannot.
