Four plug shapes, and the countries named for each
TESSAN NT009-US universal adapter, 4-in-1
A one-body universal adapter that names the countries behind each of its four plug shapes, with 20 watt power delivery on USB-C.
Four plug shapes from one body, and — better than most — the countries written out behind each: Type C for Italy, Spain, France and Germany, Type G for the UK and Ireland, Type I for Argentina, Australia and China, Type A for Japan, the USA and Mexico. “Over 150 countries” is a claim every universal adapter makes; a list is something you can check an itinerary against, and a plug shape is not a country.
The charging figures are published the right way too. Twenty watts of power delivery from a single USB-C port, 18 watts from the USB-A, and 20 watts as the total across all the ports — which tells you the real behavior: one device fast, or three devices sharing what one would have had. Several listings on this shelf give a per-port maximum and no total, which makes the headline number mean less than it looks. The AC outlet is rated 2,000 watts, and the size and weight are published, 3.33 by 2.01 by 1.24 inches at 3.65 ounces.
What is not here is either of the two things the top of this page says actually separate a well-built adapter. There is no mention of a fuse, and nothing about grounded three-pin support — which matters more on a universal adapter than on a single-region one, because a Type G socket in the UK is an earthed three-pin socket by design, and a British plug has an earth pin whether you want one or not. Of the eight adapters in the American half of this hub, one says it supports a grounded connection and one says plainly that it does not; this is among the six that are silent. The page does state that there is no surge protection, which is an honest absence and a different one.
One AC outlet is the other limit: three adapters on this shelf give four. And like at least six of the eleven listings here, it carries the warning in its own bullet — not a voltage converter, so check that a hair dryer or a straightener takes 100 to 250 volts before plugging it in.

What travelers ask
What does naming countries per plug type add?
It lets you check your actual itinerary rather than trusting a number. "Over 150 countries" is a figure every universal adapter claims; a list — Type C for Italy, Spain, France and Germany, Type G for the UK and Ireland, Type I for Argentina, Australia and China, Type A for Japan, the USA and Mexico — is something you can hold against a trip. Four adapters on this shelf are universal and three of them list countries by plug type, which is the right way round: a plug shape is not a country, and some countries use two.
Is 20 watts total enough?
For one phone, comfortably; for three devices, not really. The listing is careful about the distinction, which is more than several here manage: a single USB-C port gives up to 20 W power delivery, the USB-A gives 18 W, and the total across all the USB ports is 20 W. So one device gets fast charging and three share what one would have had. The adapter on this shelf with a 45 W supply publishes the same structure with more than twice the headroom, and this hub's power-bank shelf shows the same arithmetic on a battery.
Grounded or not?
Not stated, which on a universal adapter is a more significant gap than on a single-region one. A Type G socket in the UK is always a three-pin earthed socket, and a device with a British plug has an earth pin by design — so an adapter offering Type G output without saying whether the connection is grounded leaves the central question of this hub unanswered. One adapter on this shelf states that it is grounded and one states that it is not; six, including this one, are silent.
