    It's worth considering an option straight away with fast charging support - the QC (Quick Charge) standard. Remember that although each mains socket will be separately controlled, the USB ports will probably be controlled "together" (as one port). Here I tested a similar product: Short test and interior of the LDNIO SE2435 USB QC power strip with separate switches .

    Confusion, they are too similar. I was referring to the SL-PS27 or SEW3452. A rebrand of virtually the same one, still available to buy.

    Here are two presentations:
    [CB2S/BK7231N] LDNIO SEW3452 USB QC extender/charger strip .
    Remotely controlled 'smart' strip with USB C and QC? SL-PS27 - test, interior, Home Assistant

    Is it possible to draw from two 2A USBs at the same time?

    I have sent you two extensive reviews of this type of product, have you read them? Such comprehensive topics are a small who's who, and there is probably an answer to your question there too.
    Load test of two USB ports showing current and voltage readings with cooling fans .
    In the pictures above, I'm drawing 3.5A from one port and 2.74A from the other. At slightly higher currents the protection is already switching on. So yes, in general it is rather manageable to safely draw 2A each from the two ports (4A in total).

    Thanks for the hints.
    That's how I read the review, I suggested that you load from port C and A at the same time. But from the 2xA port it will also manage.

    The Gosund p1 says Total MAX 3.1A but above 2.5A there is a voltage drop, which for 3 USB ports is not much. I don't know why, but at random times the Gosund p1 strip resets the relays itself, this can occur once a week or twice a day. Does the SL-PS27 or SEW3452 also have this symptom?

    I haven't done any major testing on the manufacturer's firmware (Gosund/Tuya/others), but the essential question is, do you have it set that the initial state of the relays after power loss is "as before"? Because you can either set it to this memory mode, shorted or open.

Topic summary

The discussion focuses on selecting a TUYA-compatible WiFi smart power strip featuring 3-4 mains sockets and 2-3 USB ports with 2A output per USB port. It is recommended to consider models supporting Quick Charge (QC) fast charging standards for enhanced USB power delivery. While each mains socket typically has individual control, USB ports are often controlled collectively as a single unit. An example tested is the LDNIO SE2435 USB QC power strip, which includes separate switches for each mains socket and supports QC fast charging on USB ports.
