Ideal for Nintendo Switch and other power hungry devices
I own a Nintendo Switch and wanted to get a portable battery pack for it. The design of the Switch requires Power Delivery to charge it at a fast rate, especially while being used at the same time. Upon research, I found lots of articles recommending the Anker PowerCore+ 26800 PD, which is an excellent product, though large and heavy The PowerCore Speed 20000 PD that I purchased is a newer item and is significantly smaller and 1/2 pound lighter. It can still charge the Switch multiple times and has plenty of power to keep my other devices topped-off.

A quick comment on the included wall charger -- it is a fully capable 30-watt power supply and can be used to directly charge devices (Nintendo Switch, Macbooks, iPads, etc). Very handy!

Anker is really good at designing and packaging products, making them a joy to purchase and use. The unit itself is sleek and solid-feeling, the included wall charger has folding prongs for portability, the USB-C & Micro USB cables are slim and flexible, and the included carry pouch is a nice touch.

Overall this is a superb product and I am very pleased with it.

UPDATED: PowerIQ port does NOT support the Nintendo Switch Pro Controller. USB-C is fine.
UPDATE (5/5): Anker support reached out to me when I originally posted this review. They explained that due to new circuitry on their IQ ports with regard to USB 3.1 and Type C connectors, devices would act differently compared to their older IQ port offerings. I accepted the offer and they sent me their newest lipstick-sized battery which also sported the new IQ port. This also failed to charge my Pro Controller, but worked fine with my phone and PS4 controller. I reported my findings and they told me they would escalate the issue to their engineers. With nothing else left to do, they offered a 30% partial refund on this product and let me keep the smaller battery. I didn't expect this level of support for a 4/5 review, and I feel they've earned the extra star for going above and beyond to try to sort out the issue. Something I didn't mention in my previous review was build quality. Regardless of my singular problem with this battery, this and all of Anker's charger/battery offerings are solid pieces of tech.

ORIGINAL (4/5): I'm a huge fan of Anker's chargers, power banks, and cables. So when I decided to get a USB-C PD compatible bank for my Nintendo Switch, this was my first choice. It charges the Switch just fine using the included USB-C. However, there is one criticism I need to make, though I don't know if it's truly Anker's fault. It's about the Nintendo Switch Pro Controller. I can charge it using the USB-C port on the bank with the included cable, however the PowerIQ port isn't able to charge the controller using the USB-A to C cable included with the controller. With only a single USB-A port on the power bank, this would have been a perfect choice to charge both the Switch and its controller at the same time. I find the lack of compatibility in this case odd because I saw have a 2nd Gen Astro E5 by Anker and its PowerIQ ports can charge the controller just fine using a USB-A 2.0 to USB-C cable, or even a Micro USB cable with a USB-C adapter on it (also by Anker). Why does an older (by 3-4 years) Anker power bank charge the controller while the Powercore Speed PD does not? Here's another quirk - if I try to charge the controller using the Astro E5 with a chunkier USB-A 3.0 to C cable (again, by Anker), it won't charge. Finally, I have tried several Qualcomm QC 2/3 ports across brands, devices, and cables, and they all charge the controller. However, if I try to use any other brand's "smart" ports, they won't work. Only Anker PowerIQ has had a chance to charge the controller. This leads me to believe that the controller itself may be very picky, but also I feel like it's a common enough device to be tested by Anker for compatibility with PowerIQ on its range of power banks (ESPECIALLY the Speed PD) if they're going to put "Nintendo Switch" in the title. All that said, the Pro Controller lasts so long on battery I don't foresee an issue charging it while I'm using my Switch.

Long Winded Praise of a Stupid High Quality Battery pack, with practical testing of day to day use
I feel the need to notify whoever reads this, that I am not affiliated with Anker, I don't have family that works for them, they aren't compensating me in any possible way (Anker, if you see this, that doesn't mean I'm not willing to accept your goodies ;))
I have yet to purchase an Anker product that has not been anything but exceptional. That being said, I've had a multitude of charging banks from other manufacturers that let me down; but not this one! It is exceptional :) I travel frequently and like to do so as light as possible. I have a Google Pixel Phone and Pixel C tablet; and also an iPhone 8+ and iPad Pro 12.9 (2nd gen) and Apple watch, and lastly a Nintendo switch. This battery pack gives me the boost I need very quickly. It charges the iPad much faster (up to 80%, then charging is slowed on purpose for a variety of reasons that I will not go into here). I could give you statistics and measurements, but other reviewers have already delved into their technical observations of the unit, which is great, but some people might not understand how that information would translate into their day to day use.
After fully charging the battery pack (all leds turn off when fully charged), I decided to see how long I could rely on only the PowerCore 20000 PD instead of plugging any of the above mentioned devices into a wall outlet or any other power source. Since this is already a wordy review, from here I'll try to summarize. I actively use all of the above mentioned devices daily, and continued to use them as normal. When my Nintendo switch was down to about 20%, I plugged it in, got a full charge, and I estimate that I play daily on battery approximately 3-4 hours a day. I was suspicious that the LEDs on the PowerCore were all lit after fully charging that device. Pixel Tablet, I charged from 15% to ~ 60% which was just the little boost that I needed, and I started to wonder if the LEDs were accurate, as they were all still lit. Charged my iPhone from 30% to 100%; Finally, the first LED disappeared. Later I charged my iPad from 20% to ~%99 percent (using an apple USB C to lightening PD cable) which consumed another LED. I charged my Android phone (Pixel XL) from ~15% to 100%, and the PowerCore was still ready for more. When my apple watch got low on battery (next day) I charged it from 5% to 100%. In all, I was able to keep all devices comfortably charged for 3 days (this phase I tried to avoid charging each device to 100%, because my intended usage is to just get that little quick "boost" on the go when needed). Next phase, I recharged the power bank (which was surprisingly fast, about 4 hours) and waited until my other devices fully discharged and shut down automatically before connecting them to the power bank. Also, after depleting their battery (normal usage, not by purposely leaving screen on all the time or whatever) I would completely charge to 100%. For the phones and watch, flawless and fast charging with minimal impact on the PowerCore. The iPad, on the other hand, charged fairly quickly to 80%, and it's journey to full capacity had a noticeable drain on the battery pack, but I do not find this to be surprising. After this, I charged the switch, which left me with one LED left. Instead of jumping straight to the Pixel C android tablet, I chose instead to charge my Bose QC20 noise cancelling earbuds, and also my Bose QC35 head phones, and was able to fully charge both. When the Pixel C finally powered down, the powercore was able to charge it to about 12% before that last LED disappeared.
I don't think the average person runs around daily with this many devices, I do, unfortunately (work/personal situation), and I approximate that for phase 2 testing, I could have gone 1.5 days without the need for a wall outlet. Also, it has eliminated the need to carry around various cables/wall chargers and fits nicely in my bag.
Verdict: All of my co-workers and some of my friends are tired of me talking about my battery pack. So that's kind of a negative, but it's not necessarily Ankers fault that I've been so impressed with this, but it also kind of is their fault.. I didn't expect to be so impressed with such an item. When I grudgingly clicked to purchase an $80 battery pack I had preemptive buyers remorse (even though I have had good experience with Anker products previously).. because there are much more affordable battery packs on the market. I was hoping that this would be a terrible purchase, and looked forward to complaining about anything especially the price. Unfortunately, after using it almost every day since I got it, I feel like it was money well spent. Also, if you own any other Anker product, and have had to reach out to customer support, then you already know they will bend over backwards for their customers.

First one defective, but Anker sent replacement
Update: 2/9/2018
Anker contacted me. They shipped me a replacement. I received it a couple of days ago, and was able to use it a little. First thing to check was whether it could be recharged to 100%. That passed. All four LED lights came on this time, as they should. I tried using it to charge my Nexus 6P (from 50% remaining juice) a couple of times, and the phone was topped off quickly both times. After these two uses, all four LED still lit, indicating the power bank had more than 75% charge left. This is a marked difference from the first unit. Even though I have only used this for a short period of time, I have a good feeling about this. I think the replacement is good. Thanks Anker. Upgrading my review to 5 stars for good customer service.

Original Review: 1/24/2018
Mine only recharges up to 75%. After more than 12 hours of recharging, using the included charger and cable, only 3 LED lights were lit. The fourth LED never once came on, regardless of duration of charging and cable used. I tried three different USB-C cables with the same result.

Not absolutely top-of-class, but very powerful and plenty for my Chromebook and other lower power devices
I thought this might prove a bit underpowered for my Chromebook C302, which might have explained why Anker put it on sale, but it has proven more than adequate. It takes the full four hours to charge using the included USB-C charger (actually about 30 minutes less when using the Nekteck wall charger [USB-IF Certified] USB C Charger, Nekteck 4-port 72W USB Wall Charger with Type-C 60W Power Delivery PD Charger Station for 2017 MacBook Pro, Pixel 2/ Pixel/ Pixel XL Galaxy Note 8/ S8/ S8 Plus, Black. Once charged, it can take care of topping up my Chromebook at least four times, and it does the job very rapidly. The new USB-C standard may at last have achieved what auto drivers are accustomed to: brief refueling followed by extended use until the vehicle needs more fuel.

The one possible drawback of sorts is that it has only a single USB-A and USB-C port. This provides limited opportunity for charging multiple devices simultaneously. Also, without a second USB-C port, the power bank can't be recharging while in use. The competing RAVPower 26800 USB C Power Bank RAVPower 26800 PD Portable Charger 26800mAh(Faster Recharged in 4.5 Hours &USB-C Input, 30W Type-C Output)for Nintendo Switch, USB Type-C Laptops, 2016 MacBook Power Delivery Support theoretically allows the power bank to keep recharging through a dedicated USB-C input port while providing power through another USB-C output. This may be less of a weakness than it seems. How well will the lithium polymer cells inside the unit hold up while simultaneously charging and discharging? I for one have my doubts about this, but am open to learning what the experts have to say after conducting further research.

For the present, I find the PD 20000 to be more than adequate for what I want it to do.

Issues with iPhone X
I’m having a big problem with this kit and an iPhone X. It works perfectly unless power is interrupted. If that happens, charging will not resume and the only solution is to unplug the cable from the phone and replug it. So let’s say that I go to bed and start charging my iPhone X to the wall charger, and in the middle of the night there is a power flicker (happens often in airplanes), or the power brick is nudged slightly. By the time I wake up the phone’s battery will be near empty because charging did not resume after the interruption.

This happens with both the wall charger and the battery so it seems to be a problem only with Anker circuitry. I tried plugging the iPhone X to an OEM MacBook charger and it works perfectly and resumed charging after an interruption.

So yeah, it works great and charges very quickly unless power to the wall charger or battery is interrupted at which point it won’t resume until you unplug the phone and replug it.

AWESOME Power Bank. It's saving my MacBook through the day.
Great device. I was having issues with my Macbook Pro 2017 running out of battery half way through my day. I have a line dock order and waiting to be shipped, but I needed something that can give me extra juice. Enter, PowerCore. This device is AWESOME, it charges well and when connecting it to my macbook works like a charm. Full disclosure, my cat chewed the USB C cable that came with the PowerCore, so I ended up using the Apple-provided​ cable. Initially, when I plugged it in, it did not take the charge, so I flip the ports and it worked (strange). Since then I bought a USB C Fast Charge cable and it works great. Five stars, without a doubt.

Great Product! Great Results
I received my PC 20000 PD on time, as promised. WOW! What a speedster! Works as well if not better than the claims. I have had great experiences with the folks at Anker previously, and that drew me to them when I bought a new phone and needed a new Power Bank. I can tell you from experience, these people are GREAT to work with. I will continue to do business with them in the future.

I’m a Switch owner and could not be happier!!
I’m very picky and check a million reviews before buying something. This is the battery pack I landed on. It’s a bit on the expensive but well worth it. For a 20k powerbank I was surprised on how compact it was. This thing will literally charge you switch up as you play the console in portable mode multiple times fast too. That’s all while playing Zelda BOTW! Could not be happier! The thing takes around 4 hours for a full charge which is crazy. On a regular charger any other battery pack with this capacity will take well over half a day. Do not hasitate to buy this!

Fast Recharge
This item is a top of the line item. Most Anker products are though. I really liked how this power bank recharges in less than 6 hours (with the included Wall Charger) instead of 20+ hours like power banks of similar capacity.

I think I have a new favorite brand when it comes to this type of market.
