Brought one of the 8GB Ram ones from PBTech yesterday loving the phone but man the USB charger that they do include is not a good choice. It's a Samsung Fast charge which looking on their site is $44 the stupid thing is that a cheaper one would actually give a quicker charge.
The one included can only do 5V 2A and 9v 1.67A(Which the OnePlus 5 cannot use) where as there are other ones they sell that will do 5v 2.4A for less money. Someone there brought into the Samsung marketing.
