Anker PowerCore 20000 power bank review

High in capacity and super-fast, for extended stays away from mains power the Anker PowerCore 20000 power bank is an essential gadget for keeping your phones, tablets and other mobile devices powered up.

Our Verdict

The Anker PowerCore 20000 offers more power than you’re likely to need and, while it’s smaller and lighter than many at this capacity, fast charging means you won’t need to carry it around longer than necessary. A great buy if you’re going to be away from mains power for several days.

High in capacity and super-fast, for extended stays away from mains power the Anker PowerCore 20000 power bank is an essential gadget for keeping your phones, tablets and other mobile devices powered up. Also see: Best power banks 2018

As we enter the festival- and holiday season, a power bank such as this really comes into its own. It can keep the kids’ tablets topped up during long journeys or flights (you can take anything up to 27,000mAh on a plane), and keep your phone going through several days pitched up in a tent.

They come in all shapes and sizes but, in general, the higher-capacity the better, since you’ll get more charges for your phone or tablet before they need refilling. This Anker PowerCore 20000 has a 20,000mAh capacity, and with an industry-standard 60- to 70 percent efficiency you should get five full charges for a Samsung Galaxy S7 or seven charges for an iPhone 6s. See all power bank reviews

The problem with high-capacity power banks is they tend to be big and heavy, and can be rather expensive. Anker has changed all this with its PowerCore 20000, which is said to be 30 percent smaller and 27 percent lighter than comparable power banks. It’s the smallest power bank of this capacity we’ve ever seen, and although you probably wouldn’t choose to carry this 369g slab in a you could if you so wished.

If it’s still too big for you, this PowerCore 20000 is big brother to the awesome Anker PowerCore 10000 we reviewed earlier this week.

Rounded corners and a tough plastic shell make the Anker PowerCore feel sufficiently rugged for throwing into a bag and taking on the road, and its minimalistic black casing helps it to slip away without drawing too much unwanted attention. Anker also supplies a mesh carry case, which lets you keep together both power bank and cable, ready for when you need them. Also see: Best MiFi 2016.

The PowerCore 20000 is also affordable for a power bank of this capacity, available to buy from Amazon UK for £27.99 (or 49.99 from Amazon.com). We think that represents excellent value, especially when you take into account that Anker is one of the best-known names in charging tech. Also see : How to improve smartphone battery life.

We wouldn’t expect to find an LCD screen at this price, but the four LEDs Anker uses to show how much power remains in the bank become less useful (with bigger jumps between each) the higher in capacity you go. A single button on the PowerCore’s side lets you see how much power is left using these LEDs, but it’s not needed for charging, which begins automatically when you plug in a USB device.

anker, a1287, powercore, essential, 20000mah

That low price is even more appealing given the fact the Anker PowerCore 20000 supports the latest standard in fast-charging tech: Qualcomm Quick Charge 3.0. One of its two USB outputs supports this new standard, which can charge compatible devices (for example the HTC 10, Xiaomi Mi 5 and LG G5) up to four times faster than a standard phone charger. It’s backward-compatible with older Quick Charge protocols, and even if your device isn’t compatible it offers fast charging. Also see: What is Quick Charge 3.0? Best QC3 accessories

The second USB output is rated at just 1A (or 5W), but has IQ tech that cleverly recognises your device type and delivers the optimum charge. Also see: How to charge your phone’s battery faster.

Fortunately, given its huge capacity, re-fuelling the PowerCore is a speedy affair with a 2A (10W) Micro-USB input. It’s a shame that the power bank doesn’t support passthrough charging, which enables you to power up both the power bank and any connected devices from a single mains outlet, but Anker says this feature has been disabled to avoid any negative impact it may have on the battery.

Review: Anker PowerCore Metro Essential 20000 Power Bank

Most high capacity power banks these days tend to use some sort of fast charging tech like Power Delivery or Quick Charge. The more common fast charging tech that they use is Power Delivery as it’s useful for charging smartphones and laptops. It’s quite rare for a power bank to have a USB-C port for it to only be used as an input port to recharge the power bank.

However, that’s what this Anker PowerCore Metro Essential 20000 power bank features. The USB-C port can only be used as an input port. So let’s see if that’s a good or bad thing.

Power Capacity:

Going by the name, you probably know how much power capacity this power bank has and that would be 20,000mAh. A good amount of power for charging smartphones we would say that a 20,000mAh power bank may be more fitting for charging a smartphone now than a 10,000mAh power bank. This is because most smartphones have larger batteries. A few years back, smartphones with 3,000mAh batteries use to be considered as having large batteries.

Now we’re to the point where smartphones are going even higher. The new Samsung Galaxy S20 has a 4,000mAh battery, the higher-end S20 has a 4,500mAh battery and the highest end S20 Ultra has a 5,000mAh battery.

With all that said, this PowerCore Metro Essential can charge most phones to full power about three to four times. Charging tablets that would have a 5,000mAh to 7,000mAh battery can fair about two full charges from this Anker power bank.

You won’t be able o charge tablets with this power bank as it does not feature USB-C Power Delivery charging.

Output Charging:

Okay, so when you see a USB-C port on a power bank you likely think that it’s an output that you can use to charge your smartphone or laptop. That’s not the case with this Anker power bank.

The only output ports that you can use to charge your devices are the two USB-A ports. Neither of the USB-A ports uses Quick Charge. The ports have a 5V/2.4A (12W) charging speed, and if you’re using the two ports at the same time, the max output is 3 Amps (15W).

So if you have an Android smartphone that is Power Delivery or Quick Charge compatible, just know that this power bank will not be able to fast charge it. The same is true for iPhones that are Power Delivery compatible. It only features standard charging.

Input Charging:

The recharging part of this PowerCore Metro Essential power bank is somewhat more interesting than the output charging. That’s because two input ports can be used to recharge the power bank, but they can only be used one at a time.

One is the USB-C input port and the other is a Micro-USB input port. Either of the input ports recharges the power bank at the same 12W recharge speed. It would have been helpful to have a USB-C input port charge the power bank faster as it’s a USB-C port and in general it’s more powerful than the Micro-USB input port.

Size and Weight:

The size of 20,000mAh power banks a few years ago use to be quite large, but that has changed drastically and we’re to the point where 20,000mAh power banks are about the size as 10,000mAh power banks. This power bank has a length of 6.2 inches, a width of 2.9 inches and a thickness of 0.8 inches The power bank is about 8 ounces.

anker, a1287, powercore, essential, 20000mah

So even with its 20,000mAh power bank, you’re still able to place this charger into your

Functional Components:

If you’ve ever used an Anker power bank before, then you know what you expect here.

The charger automatically starts charging when you connect a device to it. There is a power button at the top and it has four white power indicators to show the remaining power capacity.

Structure and Material:

The build of the charger is solid, except for the top where Anker placed a fabric covering. There is still plastic underneath it, obviously, but it’s pretty cool to have and it adds some grip to the power bank.

Tech:

There is no heating up to speak of from this power bank and this can be attributed to the fact that it doesn’t use any fast charging tech.

Reliability

A 20,000mAh power bank with two USB ports is going to be reliable for basically anyone to use to charge their smartphone.

However, what this Anker power bank is not reliable for is for fast charging your smartphone because it does not feature Power Delivery or Quick Charge

Summary:

It has enough power capacity to charge your smartphone to full power a few times, but it does not feature fast charging tech, and he USB-C port can only be used as an input port to recharge the power bank.

It’s a small power bank for one that features a 20,000mAh power capacity.

The Anker Metro Essential power bank does look different than other power banks from Anker, but with its fabric top, it gives a good grip. The charger doesn’t overheat either, likely because of its lack of fast charging.

The charger will be able to charge your smartphone to full power a few times, but it won’t fast charge it with its high capacity.

Specs for Anker PowerCore Metro Essential 20000 Power Bank:

Conclusion:

Anker’s PowerCore Metro Essential power bank is a great standard power bank that offers a great standard portable charging experience. Just know that you won’t be getting any fast charging, but you’ll still be getting the exceptional quality that Anker has to offer.

Anker PowerCore Essential 20000 PD Review

  • Nintendo Switch (2019): 12 hours of play
  • Nintendo Switch Lite: 9.5 hours of play

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.

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.

Summary

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.
