The Anker PowerCore+ 20100 has three USB ports, which include one USB-C port and have a combined maximum output of 6A. After some testing with an Android app called "Ampere", the battery does indeed deliver a sufficient current that is safe and steady for my smartphone, although I have yet to actually fully deplete the battery due to it's monstrous capacity at the

It still has the same feature like Fast Charging Tech (PowerIQ) and VoltageBoost combine to provide the fastest charging possible which I love since it detect the device your charging and put out the max 6A output charging speed enough to charge Apple MacBook with the USB-C Cable (included in the package).When charging with the PowerCore+ 21000 (or any iAnker portable battery

Overall, I want to like this portable battery, but it gives me almost as much frustration as use, and I hope that Anker comes up with a better solution within the USB-C paradigm.

This is hands down the most impressive portable battery I have ever seen

Anker is the best, this is my second portable battery!I am very satisfied with it, I never have to worry about dead batteries!

I plan on only using this battery to charge my phone over the next few days until it dies

Since the battery is only 70% efficient because of the loss of energy through heat generation, I wish Anker would just label it 14000mah power bank

The battery also seems to drain when sitting around faster than the other anker battery banks, finally this thing is seriously heavy.

All portable batteries must be under 20k mAh.

This one battery can support all your devices no matter what it is

I love this battery, but it is gigantic and heavy.

20000mAh 4-Port Aluminum Portable External Battery Charger with 9V/12V Multi-Voltage Port and PowerIQ Technology for Smartphones, Tablets, and more

Excellent product, but could have better instructions for outputting charge through USB type C. Besides that minor bit, this is the best battery pack I've ever used!

Finally, I recently had the chance to take this portable battery on a 4 day trip with several gadgets including: 2 iPhone 6s, 1 iPad mini 2, 1 Macbook Retina and an Apple Watch

I keep this battery in my backpack to top up my phone (I usually add around 25% each time), and I only need to charge this battery once every few weeks

Outstanding battery pack for all of your USB charging needs!

Surprisingly I can be doing pretty intense work while plugged into the battery pack and maintain a positive charge without it draining my macs battery

This might sound like a "duh" review to many, but after wasting a lot of time with the other battery* and even starting to fear it would damage the battery of my MacBook, this was a critical issue to me

It works as advertised and a 5v battery that puts out 6a is unique and it's ability to charge a MacBook is cool

This is one of the most compact battery pack with this power rating

This is a great battery pack

Overall, this battery is great and I would highly recommend it

Anker contacted me and determined I had a faulty battery and offered to send me a replacement one

I love this battery!

I haven't done any real accurate testing with it, but it's gotta charge my Nexus 5X about 10 times before I need to think about recharging this portable battery.

The battery worked fine for a while and I was initially very pleased, but it was only lightly used before it inexplicably became a paperweight

Amazing battery pack that's works really well got it for Black Friday and have been very satisfied by it since

The Anker 20,1000mAh battery is a great battery if you need lots of power on the go

Love this battery

Great battery.

I recommend this portable battery for all power hungry users, it packs a lot of juice and will charge your multiple device multiple times without breaking a sweat

Just the best portable battery ever

I returned it and went for another brand of USB-C Nintendo Switch charging capable batteries!

So that makes for the possibility of charging three devices simultaneously (total of 6 amps out max).All in all, a fantastic external battery

Some external batteries will glow a certain color from like 20-80%

The new battery is outstanding

This is a great battery, and comes with 3 different cords.

Sure, it takes a long time to charge completely if you drain the battery, but when fully charged it is a life saver.

Awesome battery pack.

This is a solid extra battery pack, which I bought recently to replace an older Anker pack that didn't have a USB Type C port

The huge capacity is really nice, with more than enough battery to recharge my Galaxy S6 at least 5-6 times

Until the phone's battery is dead and it shuts down

The lowest we could drain the battery was 30% each day

This portable battery charger does its job

I bought this to replace an older portable battery from another manufacturer

There portable batteries are of the best you can buy

The battery is very efficient, and it also has an advanced surge protection and short circuit prevention, especially important when charging high current usb-c devices

Excellent battery for travel

I usually go on a tangent explaining reasons why, but every benchmark that theses portable battery banks undergo this thing scores very very high.

Great Battery

If you are in the market for a giant portable battery with USB C functionality, look no further, this device will suit your needs perfectly.

Best battery on the market

Fantastic battery pack!

This battery is a tank and i definitely recommend it for anyone looking for something to carry in a backpack or purse

The battery did charge up new MacBook Pro to 100% but the battery pack drained to zero

Great battery, holds a charge for at least 10 days, and can charge my Nexus 5X at least 3 times

The battery itself is awesome

Couple this with some sort of loose connection and a *shallow* USB-C jack (I've tried multiple USB-C cables, the problem comes and goes, but most cables don't go 100% into the unit - see the attached image), and if my phone is charging and then reconnects, it immediately begins draining my phone to charge the portable battery.

PowerCore+ is a great addition to my collection of portable battery; have it packed in my backpack with my work laptop which I take with me every morning

If you are a Nintendo Switch owner I cannot think of a better battery pack.

great battery

Charge both devices overnight and you will find that you can get a good 4+ hours off the battery before you start to deplete the internal battery.

Meanwhile, the unit has a strange way of determining - if something is plugged in, the unit defaults to charging the battery, while if the button (the only one) is pressed, anything plugged in for the next few seconds will begin charging from the portable battery.

This battery is a tank and i definitely recommend it for anyone looking for something to carry in a backpack or purse

It's a great battery

I will gladly sacrifice that pound for the peace of mind in knowing I'll have enough battery on any device I own for as long as I need it.

I highly recommend this battery

which is a battery hog I still gain charge

On the plus side it's very solid and you won't be able to crush or or damage the batteries

Such a great battery

Wonderful battery pack

I've had a lot of smaller and easier to carry portable battery packs but this one is the best

Would highly recommend Anker and this battery as a result.

The battery itself seems great, and worked flawlessly the first time I connected it to my Moto Z Force via the USB C to USB C connector that it comes with

The battery holds a charge well and charges up your device faster than any other power bank I've ever used

The battery itself seems great, and worked flawlessly the first time I connected it to my Moto Z Force via the USB C to USB C connector that it comes with

Especially if your battery is almost dead when you are charging

My favorite battery

It makes the portable battery feel much nicer and less flimsy than other competitors

I gain roughly 15% per hour battery on the Switch

Battery may be fine, I haven't used it much, but the manufacture insists on spamming you after you buy it.

I now keep this in my backpack along with a USB-C cable at all times and have never had to deal with a dead battery again

This is the best battery pack on the market

This external battery works perfectly as a portable charger for the Nintendo Switch

This is honestly one of the most outstanding battery packs I've ever used

Battery works as advertised

The second is that when you use the USB C port to output charge, sometimes the battery thinks it's gaining charge, and simply does nothing

Very handy battery pack.

It is the perfect traveling battery and will keep your devices going for plenty of time, especially while your waiting at the airport

and it's losing battery while the anker power core is connected to it

Anker did it again, this is a fantastic battery with robust build and fast charging

Great battery pack, one of few I could find that charged via USB C. Charges my phone very quickly too.

I have thrown out all the free portable battery packs I been given and just travel with this now

Good, verified battery capable of using USB-C for both charging itself, and other devices

This is now my go-to portable battery because I can charge up my Nexus 6P on the go, not to mention any other devices I have

** Anker reached out to me to replace my battery or refund me

I have multiple anker portable battery chargers

This thing is HUGE, as big as an old-school replaceable laptop battery.

I would highly recommend this product to anyone looking for a portable battery solution.

Excellent battery, not too big nor heavy for its capacity

The PowerCore+ has amazing battery life and can charge a rediculas amount of devices in one session

Probably the best external battery out there right now.

This is the best battery charger I've ever used by far

I highly suggest this battery if you want a USB-C rapid charge capable battery.

charge my switch for a few hours, charge and ipad, and a phone, and still have enough battery left.

Ok, it's a great big honking battery that charges over USB-

great battery, durable casing

in fact, I was TRYING to drain the battery and failed.

The macbook reports "Power source: power adapter" but the battery reads "Not charging" and it's slowly draining the battery

Build Quality:This charger has the highest build quality of any portable battery that I have owned

I own 5 portable batteries of various brands at this point and this is easily the best quality and fastest charging one of them all

As for the product itself, its a good battery pack as

This battery DOES NOT support USB-C power delivery, so if you need to charge the Switch as fast as the Switch power adapter, make sure to buy the Anker PowerCore PD instead

This battery was great, I could run my MacBook on USB C and essentially double my laptop's battery life

This is the perfect large capacity battery for the task

I was happy to see this kind of support, as I have recommended their products (especially their external batteries) to friends over the past couple of years

I haven't tested a full battery drain for the switch, but it always topped off my battery when I was around 60% and didn't take very long to charge it up

The first battery I got had a problem and would only charge about half-way

I never got the opportunity to charge it fully from a depleted battery during my

As far as the battery itself, I couldn't be happier

Solid battery, albeit rather large

This is an incredible battery, and I think it's necessary if you own an Apple Macbook and travel around a lot

Also charges my ipad mini 4 and my LGV20 phone quickly without the battery or device getting very warm

Great battery back up for any USB or USB C items

I was able to charge my device multi times in the past 5 days, I can’t believe how much this portable battery packs

Another great battery pack

, this battery worked well, but after 5 months of use (about 1x daily), it no longer holds a charge

Great battery bank.

Simply plug it in to the bank on your way to work and presto, 50% or more battery

I was binge playing Zelda and the Switch has a horrible battery

Anker is the best, this is my second portable battery!I am very satisfied with it, I never have to worry about dead batteries!

Awesome battery, charges my laptop and switch perfectly

Just like other Anker products, built like a brick and has nice battery cells

The best battery pack to travel with if you have the new MacBook 12".Being able to charge this battery pack over USB-C is the best feature

Still recommended because it's great to get fast charging on a portable battery.

It will drain your phone battery to the battery bank.

Great battery pack

Great battery pack

Great external battery that chargers all your devices

Very nice High-Capacity Premium External Battery, Portable Charger for the Nexus 6P with the USB-C charging port

Love this battery it's made with great quality as

Great long lasting battery with quick charge.

Best backup/external battery pack i have used

The USB-C standard is still somewhat of a new technology at this point, making a good choice for a Nintendo Switch external battery somewhat difficult to decide upon

There aren't many batteries available that can power the new MacBook which is why I selected this.

I was able to put the battery to the test charging multi device to see how much juice this portable battery packs, I did my best trying to keep track of the time it took to

Fast shipment, and long lasting battery that has provided multiple full charges for my Samsung Note 5 phone.

Pretty sure Dell did this so that you buy their expensive $200plus battery pack for this

Great battery

FANTASTIC battery

Only issue is that it does not push out enough juice to be using the laptop and charging it at the same time, you will still burn battery at a faster rate than this is able to recharge

Great, huge battery pack.

timeIt even charges as I play a game that drains the battery pretty quickly like Zelda BOTWPerfect Nintendo Switch accessory and also charges my phone and other devices as a bonus!

There are many portable battery chargers out there

My thoughts are that this is a fantastic battery

My old Galaxy S5 drained its battery quickly, this would keep my phone and other gadgets charged throughout the day

I already owned a battery that presumably could accomplish this*, but failed dramatically to do so: instead of consistently charging my MacBook, that battery would randomly "decide" to start charging FROM my MacBook for no reason whatsoever

Yes, I've tried solar but most take absolutely forever and just are not worth the struggle if you actually drain the battery during the day using GPS or weather apps

The battery seems like, on rare occasion, that it hasn't fully charged even though it says it has

Excellent solid battery pack.

Great battery

Overall if i had known my previous battery i bought from anker wouldnt have worked i would definitely bought this then

Great battery pack, I charge it about once a

Great, quality back up battery

Compare this to any other charger and the battery would be hot and almost empty by now

We suggest Anker consider a digital LCD readout of % charge remaining (or % full when charging, by sensing which port is occupied), but still... this battery is a high-capacity winner!NOTE: if you plan to travel with it, we highly recommend getting a hard case

Once your battery died

Love this battery.

In comparison to the other two PowerCore+ batteries, the 13400 and the 10050, this external battery cannot be Quick (re)Charged, although in my honest opinion I wouldn't like to Quick Charge a battery of this capacity as that could possibly decrease the battery life and speed up decay, so no problems there

Awesome battery

The 26800 comes with significant more battery capacity, quick charge, 3 ports, and its own wall chargerAnd the cost?$4 more?lmao, don't buy this

First of all the PowerCore+ itself, because of the inclusion of a USB C input, charges overnight which is the only reason that a battery this big is usable in daily life

It is able to charge the switch on portable mode while playing Breath of the Wild, which apparently is a difficult thing to find in a portable battery

Than look no further my friend for you have found the ultimate portable battery.

I love that the battery quick charges as well, so I can charge it for a few hours and get a nice charge

I am happy to see it return!In actual use the battery charges quickly, as you would expect, and holds a charge for an extremely long time in storage, which makes it ideal as a travel battery.

Fantastic, durable, powerful battery

Great quality, and long-lasting battery.

Pro: excellent battery packCon: very heavy

Anker immediately shipped a replacement battery (brand new in retail packaging) without requiring me to ship the defective battery back

And that is why, even though the battery itself is fantastic, I am giving the kit a two-star

I love the battery, but I'd give it 5 stars for the customer service alone!

Think about a day-long PokeHunt, or an Eurotrip with no places to plug, this will be the the right battery (capacity, weight, sturdiness)

I know that there are many reviews out there that say that these are the best battery packs out

Good battery durability and good materials

Definitely a shame for such a pricey battery.

With that said, the battery feels solid

best battery pack out there wouldnt trade it for another

It's a high capacity, solid battery pack that's not too huge in size

This battery is awesome.

timeIt even charges as I play a game that drains the battery pretty quickly like Zelda BOTWPerfect Nintendo Switch accessory and also charges my phone and other devices as a bonus!

Great battery provides my MacBook Pro and my phone with enough juice to make it through a day

I really like this battery

So then I wonder if it drains the battery.

We might return it... we want a super battery with a charger.

If you leave the phone plugged into the USB-C port, once it finishes charging the phone to 100%, the charge will switch direction and the battery will proceed to drain the phone completely.

I originally bought this on a lightning deal as a faster battery for my Nexus

Overall this is an excellent battery and it hasn't failed me once

This portable battery is a life saver

I would definetly recommend this battery.

Before I needed to be stingy about allowing others to drain my battery, but this stores enough power that I don't need to worry about sharing

My point with the review is that going outside of the micro USB standard does not give this battery an advantage

This is the best battery bank i have ever bought

Battery is still working perfectly fine

awesome battery, best upgrade I have ever done

The battery is really great and also Ankers costumer service are really friendly and the best part they offer an 18 month warranty

This is a big/solid/heavy battery, but it can charge my pixel (phone) at full speed many times over which is useful for travelling

Works exactly as I expect it to

It simply does not work as it is described

n’t know the new replacement will work properly or not
