12V USB Car Phone Charger Plug

WLM21

Are all USB charger plugs OK to use for all phones.
I had a plug-in USB thingummyjig in the car, which worked OK, although it never was a fast charger, but it worked.
Now, i want to buy a new one and notice they have different voltages etc.
Will any of them do ? .. they vary in price so much
this sort of thing .. https://www.amazon.co.uk/QQEG-Charger-Detector-Charging-Smartphone/dp/B07H2VDPNF/ref=asc_df_B07H2VDPNF/?tag=googshopuk-21&linkCode=df0&hvadid=311059984004&hvpos=&hvnetw=g&hvrand=16086740233875732314&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=1006956&hvtargid=pla-574377676791&psc=1

Unbranded item so who knows what the quality will be like.  Buy a box of 100 and some maybe better than others.
Seemingly identical parts sold under many brand names, buy enough and you can have them with any brand you like.
Are they indentical inside? Probably not, some will be inferior, less protection and cheaper parts.

Are they reliable and using decent branded quality parts or the cheapest parts possible?   Its probably fine until
it fails then what happens?  Will it fail in a safe manner cutting output power or will it send 12v to 14v directly

to your device?

If you want something decent buy a branded item.

If its USB it will be 5V. Higher amps will give faster charging. As above, cheap ones are likely to be poor quality with a lower output than claimed. I had one like the one you linked to which shows the battery voltage. It was very inaccurate.

I have 2 of these, not available any mone.
But great chargers.
Front one, charges IPad Pro 12.9”, Poco F2 Pro, Dash cam, sat nav and Nokia 8.1.
Rear one powers, portable fridge freezer, rear dash cam, power bank and kids DVD player and iPad.

Look for similar, but they are very big and don’t bend much.

I found a lot of them are very bulky. I got this one in the end which sits more or less flush with the socket and is solidly made from aluminium:
