The AUKEY PB-Y14 20000 USB-C power bank has four output ports and three input ports. It is all about options, and has enough capacity to keep up with several devices. What it lacks in charge speed it makes up for in price.

First Impression

The AUKEY PB-Y14 20000 USB-C is the best selling USB-C power bank on Amazon as of this posting. It is thin, but quite long and wide. It the same size as a Nintendo Switch with one Joy-Con removed. The same thickness and almost the same weight, too. Its unusual profile allows it to have a large selection of ports. It would make for a flexible commute or travel power bank.

Input Options

Most USB-C power banks only accept USB-C input. Some accept either USB-C or micro-USB. The AUKEY PB-Y14 is a rare triple input power model. Besides supporting USB-C and micro-USB it also supports Lightning (iPhone’s connection type). You can’t plug in more than one input source at a time. But the options mean you can recharge the power bank with most any USB charger and cable available.

Power InputMax DrawEstimated Charge Time
USB-C5V/2.22A10 hours
USB-C to USB-A5V/2.05A11 hours
micro-USB5V/1.91A11.6 hours
Lightning, iPad Charger5V/1.91A11.6 hours
Lightning, iPhone Charger5V/1.2018.5 hours

USB-C Input

  • Fastest of the three input options
  • Using a USB-C wall charger that supports 5V/3A (most do) will recharge the power bank from 0-100% in 10 hours
  • I was able to recharge it in less than 9 hours
  • USB-C to USB-A cable and a high output USB-A charger also works, but an hour slower

micro-USB Input

  • Second fastest input option
  • With equal USB-A charger a USB-C to USB-A cable will be faster

Lightning Input

  • AUKEY’s specs make it the slowest, but was same as micro-USB with 2.4A USB-A charger in my testing
  • Could reduce the number of cables iPhones users carry
  • Significant time difference between an iPad charger and an iPhone charger
Multi-Device Charging

With a USB-C port and three USB-A ports one could imagine this power bank charging lots of devices at once. And it can, but with limits. It can only output up to 3A max across all ports.

The Switch draws up to 1.90A when less than 80% capacity itself. It has the same draw whether asleep or running a game. At >80% charge the Switch draws 1.4A or less. Non-USB-C phones draw 1A or less and similar tablets draw 2A or more. You’ll get up to 3A output with more than one large device.

You should have no problems charging a phone and Switch. You should also be fine charging up to three phones using the USB-A ports. Or a phone and a couple of its accessories. But charging a Switch and a tablet means the Switch’s battery will drain while you play. Adding a phone to the mix doesn’t help. In that scenario my iPhone disconnected from the power bank after a while.

If you keep your expectations in check this power bank will serve you well. Keep in mind it is regular USB-C, not USB-C PD with higher output.

Pass Through Charging

Pass through charging is when a power bank is able to charge itself and a connected device at the same time. It is useful when you have a single USB charger available. The AUKEY PB-Y14 can do pass through charging, but AUKEY doesn’t recommend it. In the power bank’s manual under Product Case & Use it states: “Do not charge your devices while charging the power bank.” That is pass through charging.

While AUKEY doesn’t recommend or advertise it their design allows for it. In general pass through charging isn’t dangerous to your devices. But it can affect the lifespan of your power bank’s battery. It takes longer to charge devices while doing pass through. That allows more heat to build up, and heat is what hurts batteries the most.

I suggest one of two options. One, follow AUKEY’s documentation and don’t do pass through charging. Two, use pass through charging, but only as needed. And only for a few hours at most, not left overnight.

Pass Through Charging with the AUKEY PB-Y14

  • Input: USB-C
  • Output: USB-A (~50% of normal)
  • Input: micro-USB
  • Output: USB-C & USB-A (reduced rate, but better than USB-C input)
  • Input: Lightning
  • Output: USB-C & USB-A (slower than micro-USB input, but faster than USB-C input)

In all instances the output voltage dropped from 5V to ~4.5-4.8V. The current also dropped, depending on the input’s current. Again, it takes longer to charge devices when doing pass through charging. When input to the power bank was disconnected the output connect reset to its normal voltage and current.


The AUKEY PB-Y14 20000 USB-C uses lithium polymer batteries rather than lithium ion. Lithium polymer is more robust, flexible, and allows for a thinner profile. They are also less likely to leak and aren’t combustable. The trade off is less power per volume and a shorter lifespan.

With four output ports and three input ports you won’t want for an available or compatible port. It’ll charge USB-C and USB-A devices. And it can be recharge using USB-C, micro-USB, or Lightning (iPhone) cables. That should mean one less cable you’ll need to carry while you commute or travel.

Some commuters, such as myself, prefer smaller and lighter power banks. We value the total weight of our bag above all else. But others prefer to reduce how often they have to recharge and are willing to carry more weight. The AUKEY PB-Y14 would serve that second type of commuter well.

Its 20,000mAh capacity and 5V output means it’ll last longer between recharges. Three different input ports allow it to recharge with any USB charger available at home or work. It is thin enough to not take up a full pocket. But large enough that you can find it and pull it out.

I can see why this is the best selling USB-C power bank on Amazon. Output and input options. The capacity to charge several devices at once, if a limit on its total output. Pass through charging, if mixed signals from AUKEY. It doesn’t have the better performance of USB-C PD. But its price is low for a 20,000mAh power bank. Let alone one with USB-C.

AUKEY has U.S. based support contacts (web and email) and warranty service. 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 commute or travel power bank. With a backpack or messenger bag you won’t notice its weight and will appreciate its size. Don’t expect $80 performance from a $40 power bank and you’ll be happy with it. Use it to charge your Switch and phone, or several phones and accessories.
