First Impression

The Anker PowerCore Essential 20000 PD fills a niche of higher capacity for smaller devices. While a 30W/20,000mAh could do the same job limiting the output to 18W saves on production cost. Allowing Anker to offer this model for 20 less MSRP than its previous USB PD supporting 20,000mAh model.

The Essential has a large, round button on top. Used for checking capacity and activating trickle charge mode. Unlike some older models, there are only 4 LEDs on the button, not 8-10. Don’t expect the circle to fill when recharging, the LEDs cover less than half of the curve. The top also has a grip-friendly surface. But the bottom doesn’t, lessening the gripping surface’s effectiveness.

Device Testing

Check with your device’s manufacturer to verify which charging standards it supports.

USB Power Delivery Quick Charge 4 Phones

  • Apple iPhone 8/X/XR/XS/11/SE
  • Essential Phone
  • Google Pixel
  • LG ThinQ/V30
  • Razer
  • Samsung Galaxy S8/S9/S10/S20
  • Samsung Galaxy Note 8/9/10
  • Xiaomi Mi 8/9
  • ZTE Axon Pro 9/10

Using an iPhone 8 for testing we find USB PD phones will fast charge over the USB-C port. iPhones will need to use a USB-C to Lightning cable, not included. And Android phones will need a USB-C to USB-C cable, which is included.

anker, powercore, metro, essential, 000mah

For older and newer iPhones the USB-A port supports Apple 2.4A. An older, but still functional fast-charging standard. Older iPhones (4-7) can fast charge using USB-A. Newer iPhones will charge ~15 minutes faster using USB-C.

Quick Charge 3.0 Phones

  • HTC
  • LG
  • Motorola
  • Nokia
  • Samsung Galaxy
  • Sony
  • Xiaomi Mi 5/6
  • ZTE

Using a Moto G6 for testing we see Quick Charge will fast charge over the USB-A port. Anker uses their own PowerIQ 2.0 technology, which mimics Quick Charge. As such it is considered QC compatible and works with Samsung AFC technology.

The USB-C port is strictly USB PD, so no fast charging there for Quick Charge phones.

Nintendo Switch

Works well for all model Nintendo Switch in handheld/tabletop mode.

  • Nintendo Switch (original) – Charges near its max rate while playing and sleeping.
  • Nintendo Switch (2019 update) – Charges near its max rate while playing and sleeping.
  • Nintendo Switch Lite – Charges near its max rate while playing and sleeping.

It will not support the Switch’s dock, as it doesn’t offer the required output.

If you have an original model Switch (pre-August 2019) Anker’s product outperforms the rest. Their support of a 15V power profile instead of 12V allows for faster charging of the original Switch. Due to an underdraw issue of that model Switch.

Trickle Charge Mode

Anker PowerCore Essential 20000 PD in trickle charge mode

Trickle charge mode is for low power devices. Such as a Fitbit or wireless earbuds. These small accessories draw little current (60mA). So much so a power bank thinks charging is complete, and shutdowns to save power. This means a low power draw device could get only minutes of charging.

Trickle charge mode corrects for this, by forcing the power bank to stay on for a couple of hours. Allowing small accessories time to charge.

For Anker’s power bank you double press the button to activate the mode. A green LED will turn on in place of one of the blue LEDs. After two hours the power bank will switch back to regular mode. Shutting down completely shortly afterward. Or you can double press the button again to exit from trickle charge mode. There’s no harm in allowing the power bank to stay in trickle charge mode for the full duration.

No Fast Charging With Two Devices

If you connect two devices to the power bank it will disable all fast charging tech.

Both ports only support 5V. Which removes fast charging options outside of Apple 2.4A standard. There is a 15W total output limit shared between the two USB ports.

When you connect a second device you’ll notice the charging resets on the first. This is the power bank stepping down to a lower output level. If you disconnect the second device you’ll want to unplug and replug the first. To make sure fast charging turns back on.

This limitation is typical of many power banks. A few can allow for one fast charging and one regular charging. Fewer still allow for dual fast charging, and those are always large and heavy. There is a limit to how much current can cross its circuits without extra hardware. Which adds size, weight, and cost.

Whether you should fast charge one device or regular charge two depends on battery levels and your immediate needs. The closer both devices are to 100%, the less impactful not fast charging becomes.


The Anker PowerCore Essential 20000 PD is a good value option for some, depending on your devices and needs. It works bests with smaller devices, from Bluetooth earbuds up to Nintendo Switch and small tablets. Its higher capacity offers up to twice the run time as a 10,000mAh model. Good if you’re charging several devices on a day trip. Or charging one device over several days.

Anker PowerCore Essential 20000 PD ports

For phones, it fast charges all iPhones and most Androids. Notably Samsung, Google, LG, and Motorola models.

For the Nintendo Switch, it charges in handheld mode as fast as any other option. The original Switch charges faster with the Essential than its peers from AUKEY or RAVPower. But the power bank cannot power a docked Switch.

By limiting the output to 18W Anker saves on production costs, and passes that on to you. The Anker PowerCore Speed 20000 PD has the same capacity, but 30W output (and no PowerIQ 2.0). It costs 20 more MSRP as of this posting. If you need to charge a small laptop that extra 20 gets you that performance. But if you only have handheld devices the Essential gives you the same performance at a lower cost.

If you don’t need the extra capacity you’ll find a better value with an 18W/10,000mAh power bank. Such as the Anker PowerCore 10000 PD Redux. It offers the same output features. But in a small and cheaper package.

About Anker

Anker has U.S. based support (web, email, phone) and an 18-month warranty. And their own online community with forums. They are a beloved brand within many USB-C communities.

Bottom Line

The Anker PowerCore Essential 20000 PD is perfect for charging small, handheld devices for long periods of time. It’ll fast charge iPhones, most Androids, iPad, and Nintendo Switch. At a cost less than a similar power bank made for small laptops.

Buy if you:

  • Need to fast charge iPhone, popular Androids, iPad Pro, or Nintendo Switch for long trips or over a weekend
  • Want to charge an original model Switch as fast as possible
  • Prefer the Anker brand and customer support

Don’t buy if you:

  • Need to also charge a laptop on the go
  • Only need to support a single device for a few hours

You’ll want a USB-C wall charger to quickly recharge this USB-C power bank. I recommend the Anker PowerPort III Nano. A small charger for your large power bank.

The Anker PowerCore Essential PD is a really versatile power bank

Some of the advantages of the Anker PowerCore power banks include high voltage protection, current regulation, and temperature control.

It might not be sexy, but it’s very useful!

The latest PowerCore, the PowerCore Essential 20000 PD allows high speed charging, up to 18W on devices that support it. This is delivered by way of both the PowerIQ 2.0 port (USB-A) and PD via the USB-C port. Note that this is the total wattage available, so if you are charging two devices simultaneously my understanding is that you won’t get the fast charge ability.

With 20,000mAh at its disposal, the PowerCore Essential PD claims to be able to charge an iPhone XS 5.4 times, and a Samsung S10 4,8 times.

The device isn’t particularly light at 345.5G, but it is very neat to look at with a sort of brush textured finish on the top. It measures 6.2 x 2.9 x 0.8 inches making it on par in terms of footprint with a lot of smartphones, although clearly it is a lot thicker, as you’d expect. A single round power button resides at one end, and this has four tiny LEDs embedded in it to indicate the capacity that is left. These are stylishly done, but they aren’t as clear and easy to see as the bright row of lights on my PowerCore 20100. From certain angles you can’t see them. But despite this, it is at least an indication of the power left on it, which is essential if you are using it to power a camera with.

Input/output is simple. Just two ports. One USB-A and one USB-C for use with different types of device.

Connectivity is also incredibly simple, with just one USB-A port and one USB-C. The USB-C port doubles as a charger connection. If you charge the power bank from a USB-C power adaptor such as one from a MacBook Pro it can be charged back up in around 6.5hrs, while with a USB-A style charger it could take up to 10hrs. These might seem long times, but the amount of use you can get out of one charge makes it worthwhile.

The PowerCore Essential 20000 PD might not be the sexiest gadget around, but it is very neatly done, can be used for a wide variety of devices, including cameras, and gives that all important fast charge ability to the latest phones. At 53.99 it is a bargain if you look at the price of much lower powered batteries for cameras. The fact I can power the S1 effectively makes it worth the purchase alone. With more visual devices coming out that can be charged via USB-C, power banks like this are going to become a lot more useful.

The power button on the Anker PowerCore Essential 20000 PD. The power indication lights can be tricky to see from some angles.

Clearly the market is fairly crowded with power bank options. But Anker are a very dependable brand, and the performance I have had long term out of my existing PowerCore has been faultless. I can’t say the same for some other powerbanks I have tried in the past. So for this reason I can highly recommend giving the PowerCore Essential 20000 PD consideration if you are in need of such a power solution, particularly if you have purchased a camera like the S1 or S1H and need external power, or if you need a highly portable charging system for a camera like the BMPCC 4K or 6K.
