Output: 15W USB-C
Capacity: 20,000mAh

Doesn't support USB-C PD or Quick Charge, so no fast charging. But slower output gives it longer charge time. It can keep a Switch topped off for 10+ hours.

First Impression

The AUKEY PB-Y14 20000 USB-C is the best selling USB-C power bank as of this posting. You would be hard pressed to find another 20,000mAh USB-C power bank at the same price point. It is thin, but quite long and wide. The same size as a Nintendo Switch with one Joy-Con removed. The unusual profile allows it to have a large selection of ports. Unfortunately its output doesn’t allow it to take full advantage.

Switch power negotiation

Switch power negotiation

The Nintendo Switch charges at the expected ~10W with regular USB-C. Over 5V it limits its draw to 2A. But that’s still enough to charge while you play any game. Learn more about charging the Switch.

We see a less active power negotiation, as it doesn’t move up to a higher voltage. Note there is a slight delay (1-2 seconds) between plugging in and current flowing. You’ll see the same between connecting to the Switch and the Switch showing it is receiving a charge.

With regular USB-C the iPhone 8 won’t fast charge when using a USB-C to Lightning cable. In fact you’ll charge a bit slower with USB-C than you would with USB-A using a regular Lightning cable. Learn more about fast charging iPhones.

The Moto G6 and all other USB-C Android phones will charge at their normal rates. Lack of USB Power Delivery and Quick Charge means no fast charging. The USB-C and USB-A ports charge equally well. Learn more about fast charging various Android phones.

Pass Through Charging

Pass through charging allows a power bank to both recharge and charge a connected device. Some of the energy flows from the wall output, through the power bank, to the device. The remaining energy recharges the power bank itself.

The AUKEY PB-Y14 supports pass through charging a several ways:

  • Input: USB-C, Output: USB-A
  • Input: micro-USB, Output: USB-C or USB-A
  • Input: Lightning, Output: USB-C or USB-A

Any setup other than using micro-USB for the input will result in reduced output. With micro-USB my Moto G6 was able to draw up to 1.45A. With USB-C or Lightning inputs it only drew 0.25A.

Pass through charging is useful for overnight stays with limited wall chargers. It is not recommended to do so on a regular basis. It puts more heat and stress on the power bank, which can affect its lifespan. Doing it when traveling is fine. But don’t set this up next to your bed at home every night.


The AUKEY PB-Y14 20000 USB-C is one of the thinnest high capacity power banks you’ll find. The trade off it a larger than usual footprint. It also uses lithium polymer batteries rather than lithium ion. Lithium polymer is more robust, flexible, and allows for the thin profile. The downside is less power per volume and a shorter lifespan.

For the Nintendo Switch it charges in handheld mode while you play. It’ll be a slow charge with demanding games, but enough to keep up.

Its 15W USB-C output won’t fast charge any devices. But it will provide a consistent, regular charge rate to any model USB-C phone or small tablet. I wouldn’t recommend it for any model iPad Pro, especially if working on the go.

With a USB-C port and three USB-A ports the first thing you think of is charging lots of devices. Unfortunately the specs don’t back that vision. There is a 3A limit across all ports. If you plug in a Switch and phone you’ll get ~7.5W per device. Plugging in a second phone will reduce that to 5W. The multitude of ports would only be handy if charging several small accessories. Such as AirPods or Fitbits.

Three three different input ports do offer flexibility when recharging the power bank. You can use whatever charger and cable you already carry. There is a charge time difference, with USB-C being the fastest and Lightning the slowest. For commuting and travel it could mean one less charger and cable set to carry around.


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 PB-Y14 20000 USB-C works well as a large commute or travel power bank. A good cost per capacity value. Will easily keep your Switch and other devices topped off. But don’t expect fast charging speed at this lower price point.
