    A 33W Anker isn't that impressive.

    Most laptops require more…

    FYI, this is not a GAN charger - which is a good thing if you want uninterrupted power on either of the ports. (With a GAN charger, the ports will all stop momentarily whenever you plug something else in, to renegotiate charging. That makes (multi-port) GAN chargers bad for any device that needs uninterrupted power, like a baby camera or something.)

    If you want a portable phone charger, and don't need the second port, I'd highly recommend the Anker 511 (GAN charger, but single port anyway so re-negotiation isn't an issue) - it's tiny!

        My baby camera will fully reboot whenever it loses power - this takes quite a few minutes for it to restart and reconnect. So not ideal.

    • powerhead on 29/04/2024 - 12:22

      I have this charger and it also interrupts power when plugging in/out of the second port

      • caprimulgus on 29/04/2024 - 12:24

        Both ways, or just the USB-C port?

        It makes sense for the USB-C port to be interrupted by plugging in a USB-A (if the power needs to be ramped down from 33W to 20W when shared), but it shouldn't interrupt the USB-A when plugging in a USB-C.

        • powerhead on 29/04/2024 - 13:15

          Pretty sure it’s both ways. I seem to recall both the laptop and the phone making the ding sounds when the other one is plugged in.

          • caprimulgus on 29/04/2024 - 14:23

            @powerhead: If you can be bothered, could you try plugging in USB-C while USB-A is already plugged in, and see if it's interrupted. Just to confirm.

            I was going to buy one just for that, but won't bother if it doesn't work as expected. Cheers.

              @caprimulgus: I checked mine, and USB-A is definitely interrupted when USB-C is connected.

              Both the USB-A or USB-C port can do up to 33W at 20V. And the USB-A port can do up to 22.5W (5V, 4.5A). So it renegotiates every time.

      GaN is just the material the transistors are made out of. (Instead of the usual silicon).

      It has nothing to do with power negotiation causing dropouts. Negotiation is caused by the charging protocol i.e. USB-PD

      So GaN makes no difference to what you're talking about.

      • caprimulgus on 29/04/2024 - 16:23

        Yep, you are correct that it is not GAN per se that is doing that. What I mean is that all GAN chargers do it (just because they are made that way, not because of the GAN, as you rightly point out).

        Not at USB-PD chargers do it. It seems that this one does, but i do have USB-PD capable charagers that have the USB-C PD circuitry seperate (and thus, dont do it).

      Yes it does if nothing is plugged into the USB-C at the same time.

      If you use both ports then it's USB C 20w + USB A 12w.

      The other posters evidently haven't looked at the specs printed on the charger.

      • caprimulgus on 29/04/2024 - 16:28

        Yes, you are correct.

        I only looked at the marketing images, which had 12W max on the image (which I mistook for the actual max). My bad!

    There seems to be a bit of confusion about GaN and non-GaN chargers with regards to uninterrupted power supply. I've started a forum discussion to help clear things up. https://www.ozbargain.com.au/node/843481

    • johnwickspuppy on 25/05/2024 - 14:57

      If anyone reads this and cares, the interrupted power supply seems to only occur to the USB-A port when plugging/unplugging USB-C. The reverse scenario doesn't interrupted supply for some reason, so when plugging/unplugging USB-C. Anyone else experience this too?

      • powerhead on 25/05/2024 - 15:06

          I thought I better test again to be sure. 2 USB-C phones and, obviously, 1 USB-C to USB-C cable and 1 USB-A to USB-C cable. Can confirm my comment above about power interruption only occurring on the USB-A port.

          • caprimulgus on 27/05/2024 - 11:01

              @caprimulgus: Yes you were 50% correct! I'm surprised by the results of my experiment to be honest. I'm no electronics expert so I don't understand why it exhibits this behaviour. We should still wait for Powerhead to report back this week.

                @johnwickspuppy: apologies for a late test - usb-A is always interrupted for me; usb-C is NOT. I use the charger with MacBook Air on -C and iPhone on -A. However MacBook battery is currently over 90%, looks like according to excellent @Prong's explanation below this is expected behaviour.

          • Prong on 27/05/2024 - 14:13
            +2

            @johnwickspuppy: So to add to this, I did some extra testing.

            As has been noted, the USB-A port is always interrupted when the USB-C port is plugged in or out.

            The USB-C port is interrupted any time it is not using the (5V 3A 15W) or (9V 2.22A 20W) PDOs, and the USB-A port asks for more than 5V 1.5W.

            EG, if you are running a laptop at 20V via USB-C, and plug something into the USB A port that wants more than 1.5W (like a phone) then the USB-C port will disconnect power, reconnect, and tell the laptop there is only 5V 3A or 9V 2.22A available. If you plus something that uses less than 1.5W (like a USB light, or charging some earbuds etc) then the USB-C does not disconnect.

            So if a phone is charging from the USB-C port using PPS (EG, 8.5V, 2A), then plugging something in to the USB-A port will cause the USB-C port to negotiate to charge at 9V and up to 2.22A (or 5V 3A). The switch from PPS to 9V 2.22A is extremely fast and seamless, so the phone does not indicate charging has stopped. I will have to log the voltage change with a high sample rate to see if it actually disconnects or just adjusts the voltage up as it changes PDO.

            If you are charging a phone from USB-C using the 9V 2.22A PDO (which is most common with phones) or the 5V 3A PDO then plugging something into the USB-A port will not cause the USB-C port to disconnect.

            This is because when both ports are in use, the USB-A port is limited to a maximum 5V, 12W. And the USB-C port is limited to 20W. So if the charger already knows the USB-C output is no more than 20W, it doesn't have to renegotiate it when the USB-A port is used.

            @johnwickspuppy In your case, the phones are likely using PPS (seamless switch), or already using the 9V 2.22A or 5V 3A PDOs.

              @Prong: Wow! What a write up! Thanks for the investigation and detailed explanation. I find some of it confusing as I'm no expert in electronics or anything, but I definitely get the gist of it. I created a forum discussion on this and I'll be sure to link this.

                @johnwickspuppy: Haha yes perhaps a bit too much detail. But how else to relax during lunch than by testing USB chargers?

                The less complex version is that if charging anything that uses more than 20W (like a laptop or some phones), the USB-C port will disconnect and reconnect when plugging something into USB-A.

        I've used mine several times to charge one or two devices overnight and mine seems to be working ok too. Charges fine and temperatures are typical for a non-GaN.

        No changing on either port. Other chargers work with the same cables.
