Anker’s 13,400mAh Switch-branded power bank is much smaller than some of the previous power banks produced by the accessory company. The 20,100mAh model has been the go-to recommendation for Switch gamers since the console debuted last March, but this newer model is much more portable while still providing over a charge and a half of extra play time.

It’s a bit of a fingerprint magnet…

The power bank features one USB-A and one USB-C port, so you can charge two devices at the same time. A small Anker logo appears on the front of the power bank and there is a series of eight tiny white LEDs that indicate how much juice is left in the power bank.

Flipping it over, you’ll see a Nintendo Switch logo branded on the back of the device. It’s simple, weighs just nine ounces, and it is made out of a soft-touch material that reveals fingerprints like nothing else.

Anker includes a small felt bag to store the power bank when it’s not in use. It’s a nice touch, but I’ve been using mine to store extra cables rather than keeping the power bank inside of it.

Anker PowerCore Charge Times

Test #1: Charging Switch with screen off

To test how long this power bank will take to charge a Switch, I completely drained my Switch battery down to 0% and then plugged in the power bank and set an interval timer to check on the charging progress every 10 minutes. The Switch screen was turned off the entire time and was only turned on at every 10 minute interval to record the charge percentage. Here’s a peek at the data from this experiment showcasing how long it takes this power bank to charge the Switch’s 4,310 mAh battery.

   Time Charging    Percent Charged  
10 minutes6% charged
20 minutes14% charged
30 minutes 22% charged
40 minutes 30% charged
50 minutes38% charged
60 minutes46% charged
70 minutes 54% charged
80 minutes62% charged
90 minutes 70% charged
100 minutes76% charged
110 minutes82% charged
120 minutes86% charged
130 minutes90% charged
140 minutes93% charged
150 minutes96% charged

In total, it took this Anker power bank about two and a half hours to fully charge the Switch. It slowed down significantly once the Switch reached 85% charge, which is a normal feature of power banks and modern devices to prevent overcharge from frying your device.

An hours worth of charge will top you off at just over 50%, which means you can charge your Switch on your lunch break and be ready to go for the commute home. Keep in mind that these charging times are with the screen off and not playing games. Charging while the Switch screen is on and playing games will result in longer charging times.

Test #2: Charging Switch with screen on

Taking about two and a half hours to charge the Switch with the screen off is not bad. But can the Anker PowerCore stand the test of charging a Switch from around 10% up to 100% in one play session?

To perform this test, I let my Switch’s charge fall to 10% and then plugged in the power bank and proceeded to play a variety of Switch games like Enter the Gungeon and Dead Cells. I checked the power level every 20 minutes in this test. The screen stayed on the whole time this charging test was performed.

   Time Charging    Percent Charged  
20 minutes16% charged
40 minutes28% charged
60 minutes36% charged
80 minutes44% charged
100 minutes51% charged
120 minutes59% charged
140 minutes67% charged
160 minutes76% charged

I stopped at the 160 minute mark because I had things I needed to do that didn’t involve having fun with the Switch, but as you can see, this power bank is perfectly capable of charging the Switch while you play it. The charge rate isn’t as fast as with the screen off, but it’s still more than acceptable to keep you gaming while you’re on the go.

Final Thoughts


  • Completely charges the Switch in 2.5 hours with screen off
  • Charged the Switch to 76% in 2.7 hours with screen on
  • Light and compact enough to fit in your pocket
  • Charge two devices at once with USB-C and USB-A ports
  • Only takes about 3.5 hours to recharge the power bank


  • The svelte material it is made from is a fingerprint magnet
  • Gets mildly warm when charging while playing the Switch


The Anker PowerCore 13,400 is a great compact power bank that will give you about a charge and a half of your Switch while out and about. It’s small enough to fit into the palm of your hand and the LED ring lights on the button will tell you how much juice you’ve got left. Recharging massive power banks can be a pain, but this one only took about 3.5 hours to reach full charge.

If you’re looking for a smaller power bank than the Anker PowerCore 20,100mAh to add to your every day carry for devices like your Switch, smartphone, or laptop, definitely consider this smaller version. I’ve used it to charge my Switch and play Pokemon Go for hours on end and it has served me well.
