Tom qab QC, AFC, SCP, FCP thiab lwm yam yuav luag tag nrho cov txheej txheem ceev ceev ntiag tug (tshwj tsis yog Apple) txuas ntxiv los ntawm BC1.2.
Thaum Lub Xya Hli 2012, USB-IF tau tso tawm USB PD1.0 tus qauv, raws li cov chaw nres nkoj USB-A thiab USB-B nyob rau lub sijhawm ntawd, uas tau pom tias muaj peev xwm muab hluav taws xob ntau txog 1{{10}}0W ntawm USB 3.0 thiab USB 2.0 chaw nres nkoj, tab sis siv A 24MHz zaus, ua ke rau A lub zog hluav taws xob cov cab kuj, Vim muaj teeb meem kev ncaj ncees thiab teeb meem kev xa hluav taws xob bidirectional, nws tau hloov sai sai los ntawm USB PD2 .0.
Thaum Lub Yim Hli 2014, USB-IF Association tau tso tawm qhov hloov pauv hom-C 1.0 tus qauv interface thiab USB PD2.0 tus qauv. Los ntawm USB-C connector thiab ntxiv CC kev sib txuas lus kab nyob rau hauv lub cable, lub bidirectional fais fab kis tau tus mob thiab lub siab tshaj plaws 100W fais fab mov twb paub lawm.

PPS yog daim ntawv them nqi ceev nrog kev sib koom siab ntawm Android camp. Nws tuaj yeem ua tiav 100W high-power ceev them los ntawm kev hloov kho zoo ntawm 20MV thiab lub twj tso kua mis built-in ntawm lub xov tooj ntawm tes.
