The only adapter here that says it will NOT take a grounded plug
Anker A9215 Nano travel adapter, 20 W
The one listing in this hub to state, in full, which grounded plugs its AC outlet cannot accept — Schuko, UK three-pin and earthed laptop chargers.
One sentence on this listing is worth more than everything else on this shelf put together, and it is a sentence about what the product cannot do. “The AC outlet does not support 3-prong grounded plugs, including EU Schuko, UK 3-pin, or grounded laptop chargers.” The buying tip at the top of this page asks you to check for grounded pin support specifically, and warns that forcing an earthed plug into an ungrounded adapter is unsafe rather than inconvenient. Of the eight adapters in the American half of this hub, one says it supports an earthed connection and this one says, naming the socket standard, the country standard and the device that catches people out, that it does not. The other six are silent.
The listing goes further and gives its reasoning: a 2-pin to 2-pin design reduces the risk of electric shock. Read that as a decision with a cost rather than a feature — a double-insulated phone charger needs no earth and is fully served, and an appliance built to be earthed needs the earth it was built with. The virtue here is that you know which you have before the money leaves your hand.
The rest is a well-made small thing. A credit-card footprint at 3.39 by 1.97 by 0.98 inches, with a stated 43 per cent reduction against similar models and a photograph cited for it. Pins that retract and fold behind a locking slider, with a written instruction for extending them that reads as though somebody has been through the returns. Five devices at once from one AC outlet and four USB ports, with the figures published the honest way: up to 20 watts from a single USB-C, 15 watts maximum when shared, 20 watts total, 6 amps maximum current — and a concrete result, an iPhone 16 to half charge in 28 minutes.
Two gaps and one caveat. There is no fuse mentioned, which is the other specification the introduction to this page names, and no AC wattage rating, where four adapters here publish between 2,000 and 3,250 watts. The warranty is 18 months, the shortest term on this shelf. And it converts no voltage, which the page states in a closing note. One point of order for anyone comparing: the Anker Nano already published in this hub is a different reference with no American listing; this is the A9215.

What travelers ask
Why is stating a limitation the best thing on this page?
Because it is the exact question this shelf's buying tip tells you to ask, and seven other listings on this shelf do not answer it. "The AC outlet does not support 3-prong grounded plugs, including EU Schuko, UK 3-pin, or grounded laptop chargers" names the socket standard, the country standard and the device that most often catches people out. The buying tip says forcing an earthed plug into an ungrounded adapter is unsafe rather than merely inconvenient; this listing makes that impossible to do by accident. Of the eight adapters in the American half of this hub, one states that it supports a grounded connection and this is the one that states it does not. Six say nothing.
Is a two-pin design actually safer?
The listing argues so — a 2-pin to 2-pin connection reduces the risk of electric shock — and the reasoning is that there is no earth path to get wrong. Read it as a design decision with a cost rather than an advantage: a double-insulated phone charger needs no earth and is perfectly served, while an appliance built to be earthed needs the earth it was built with, and the right adapter for that is the grounded one further down this shelf. What matters is that the page tells you which group you are in.
How small is credit-card sized?
3.39 by 1.97 by 0.98 inches, which is a credit-card footprint and an inch thick — and the listing publishes both the figure and a stated 43 per cent reduction against similar models, with a photograph cited for the comparison. The pins retract and fold with a locking slider, and the page gives the instruction for extending them: press and hold the side button, slide until they lock, and do not force the slider without pressing the button. That last sentence is the sort of thing a maker writes after reading its own returns.
