              Neither one has missed a beat.

          • Highwaytea on 03/04/2019 - 22:10

            @lostn: It is a separate adapter. Surface Connect to USB-C Adapter.
            Will work with SP4.
            Needs minimum 27W or 12V to charge though.

            Going from memory the surface design for the power cable is the same since forever, so yeah should work.

            EDIT: Only order the cable. The powerbanks get rejected in Aus customs for some reason.

    Considering in China they sell at around $22. If you can get free delivery. It would be a good deal. Is this code accepted by cashback website? Cos otherwise the cashback would be $0

    • AssociatedClear @ Romoss AU Direct on 03/04/2019 - 21:52

      From my experience and dozens of others here at OzB coupons make no difference in tracking with the Amazon affiliate network (never has in my portal) so cashback companies will pay out.

      • ce5himm on 03/04/2019 - 22:00

        Well that's good to know, maybe it's a little different on amazon. I tried Catch last time with an unapproved code. Transaction was tracked, but the cashback amount was $0. Via shop back I remember. Anyway even without CB, still a good deal.
