First Impression

The AUKEY PA-Y18 18W PD is almost as small as iPhone’s included 5W USB charger. But where those slow charge your phone this will fast charge newer iPhones. Not to mention the Nintendo Switch. It also has folding prongs, unlike most included phone chargers. Able to fit in your pocket it is as travel friendly as USB-C PD chargers get.

Power connection with Switch

AUKEY PA-Y18 – Switch power negotiation








The Nintendo Switch charges at the expected ~12W. The Switch under draws power at 12V, maxing out at 12W. At 9V or 15V it can get up to 18W. Chargers which offer 12V but not 15V will under perform with the Switch. The issue is with the Switch, not the charger. Please note 12W is still more than enough to charge the Switch in handheld mode while you play.

AUKEY appears to be aware of the issue. They state this charger, “Doesn’t charge Nintendo Switch at full speed.”

The PD protocol negotiation with the Switch shows it connecting with no voltage, then going to 12V once negotiation is complete. It is more usual to see a charger connect at 5V at the start. But I haven’t seen any issues with real world charging performance. The current behaves normally, stepping up after the 12V connection is made.

The power bank’s USB-C port supports fast charging the iPhone 8 using a USB-C to Lightning cable. Android phones that support USB PD, like Google and Essential, will see similar results. Other Android phones, including Samsung, Motorola, and Quick Charge enabled devices won’t fast charge. They will charge around 10-12W, depending on their individual power draw.


The AUKEY PA-Y18 18W PD is a a great option for those who prefer to travel light. Other USB-C PD chargers can outperform it, but few do so at its size and weight. And the few that match its size are more expensive.

While the Switch under draws from its 12V power profile there is still enough to charge while you play. The Switch uses at most 8.9W during game play. This charger will provide up to 12W. That leaves 25% of the charge for the battery. And the Switch doesn’t draw much more than 10W while asleep, so no performance loss there. The difference between this and a full 18W charger is faster charging while you play. But that doesn’t affect your total playtime.

What you lose in performance you gain in portability. The AUKEY PA-Y18 is as small as an iPhone charger, and smaller than most Android phone fast chargers. Folding prongs make it perfect for travel. It takes up little space in a Switch carrying case and could even fit in your pocket. The smaller size does increase its temperature while in operation. But not enough to be a bother. My measurements of the external temperature never went past 86°F (30° C). And it was never too hot to handle.

As a travel charger this will also handle your iPhone or Android phone with USB-C. An iPhone 8 or X series can use a USB-C to Lightning cable to connect and fast charge. Android phones that support USB-C PD (Google Pixel, Essential Phone) will also fast charge using the same cable as the Switch. Other Android phones with USB-C will charge at their normal rate. The charger can also work on USB-C power banks, but are best left to charge overnight.


AUKEY has U.S. based support (web and email) and a 24 month warranty. You must have purchased the product either from them or through Amazon for support.

Bottom Line

The AUKEY PA-Y18 18W PD is a great charger for the minimalist traveler. It’ll keep a handheld Nintendo Switch charged while you play. And charge most USB-C phones and iPhones. What little you lose in charge time you gain in reduced size, weight, and cost.
