Looking for a multi posrt USB charger, preferably 4-5 ports, and fast charger.
Found this one (there are other similar ones): https://www.amazon.co.uk/dp/B096FF2L4H/ref=sspa_dk_detail_0?psc=1&pd_rd_i=B096FF2L4H
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?

Looking for a multi posrt USB charger, preferably 4-5 ports, and fast charger.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.

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

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.

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

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.

RAVPower were one of the brands that Amazon purged earlier this year,
for apparently doing things like soliciting (and paying for) favourable reviews.
