    Every port seems to support fast charging (3.1A), but the device is
    rated as 33W max:  33w/4 = 8.25W per port / 5v = 1.65A per port when all
    4 are utilised, which is really rubbish.

    Am I missing a trick here?

    be very careful when buying wall warts from the likes of Amazon or Ebay
    or Aliexpress..... They may either be counterfiet or do not adhere to
    CE marks or British safety standards.

    There have been many a case documents where items of dodgy provenance
    have burst into flames and the odd occasional house burnt down.

    Your buildings insurance could reduce the payout due to "contributory negligence".

    What kind of fast charging do you want? There are several kinds:

    USB-PD: modern laptops, Apple, Google
    QC: anything with a Qualcomm chip in it
    Huawei/Xiaomi/Oneplus have their own standards

    A phone should try and take up to 2A from a regular USB socket, but to go
    above that it may try and use one of those protocols to negotiate up.
    PD and QC raise the voltage to minimise losses in the cable.
    Some of the Chinese manufacturers expose the battery directly to the charger
    so the conversion electronics can live there where they are better cooled.

    That has a QC port - does that match your phone?

    What are you trying to do? Charge four phones at once? If not phones, what needs the current?

    As mentioned, many cheap chargers have dubious mains safety. This is a good comparison table - note the 'death' symbols... https://lygte-info.dk/info/ChargerIndex%20UK.html

    I'd go for a reasonably known brand, and with at least one PD port, I prefer ones where the 13A plug isn't moulded into the charger, they get a bit cumbersome, pick one with a C6 or C8 inlet.

    Depends if 12 or 20W split between the three 'A' ports is enough for you, other variations exist, the GaN ones are a bit more compact.

    Sorry, I should have been more specific:

    I take such device with us when going away. Used to charge a Samsung S20
    (which supports fast charging - at least 50% faster than "normal
    charging" from experience), a couple of kindles, another Samsung phone
    (soon to be replaced) which does not support fast charging, and a
    Samsung tablet (again, no fast charging).

    Over the last few years I have bought similar Anker charges to the one
    you mentioned - 4-5 ports, 5 in total I believe. The very last of them
    died whilst we were away this weekend. They were certainly not the
    cheapest at the time, and none has lasted more than 4 years or so. BTW,
    none of the power packs that I bought of theirs during that time (4 I
    think) has lasted much longer. All the above have had pretty minimal use.

    Looking to replace the dead multi port charger, and though that I would
    try one with fast charging as I get from the original charges that came
    with the S20 (and the phone of the little ones who are no longer here).
    All charged the phone much faster.
    When the Anker ones died I replaced them with similar RAVPower ones
    (another brand sold through Amazon). All still going strong, but Amazon
    don't seem to stock them any more, hence looking for another manufacturer.

    The ones I had were the older version (similar spec) of this one https://www.amazon.co.uk/Anker-PowerPort-Family-Sized-Technology-Smartphones-Black/dp/B00PK1IIJY

    Worked fine when they did, but last year or so their price doubled to
    the current, and from my personal experience with their products I find
    no reason to pay it.

    OK, so the S20 supports USB PD 3.0 PPS as its 45W fastest charging protocol. You may find it will charge slightly less quick (eg 25W) with regular USB
    PD.

    USB PD requires a USB C connector or captive cable on the charger. The S20 (from what I read) also supports QC 2.0 at 15W, which is supported over a
    USB A connector.

    I think the kindles are normal 2A max USB, and the other Samsungs probably
    take that too (if they don't support QC [1])

    I'd probably be looking for a supply with 1x USB-C port supporting PD (PPS
    if you can find one, but not the end of the world) and Nx USB-A ports at 2A (although more amps is nice). If you were to go for one with a QC port it would be better than normal USB but about a third as quick as PPS.

    When the Anker ones died I replaced them with similar RAVPower ones
    (another brand sold through Amazon). All still going strong, but Amazon
    don't seem to stock them any more, hence looking for another manufacturer.

    RAVpower was caught in review fraud so the group (including Aukey and other brands) got banned from Amazon. I don't have any good suggestions of non-deathtrap brands apart from Anker and Apple.
