Anker Prime Power Bank, 20,000mAh 200W Portable Laptop Charger for Travel, TSA-Approved, Smart Digital Display, 2 USB-C and 1 USB-A Port, for iPhone 16/15/14 Series, Samsung, MacBook, and More

tl,dr:Pros:CompactCharges up to 2 supported devices at 100W eachCan be charged at up to 100W itselfDisplay is informative and usefulIncludes 140W cableCan be charged with an optional dockDid not give me hotdog fingersCons:A little priceyDoesn't include charging brickIncluded cable is shortDid not give me Kung Fu abilities**Edit**The power bank might need its battery calibrated before the display will read out accurately. After using it a handful of times over the past week, I noticed that the battery seemed to be draining REALLY fast when the only thing it was charging was my phone. Like, it went from 100% down to below 70% after only charging my phone 30%. My phone has a 4000mAh battery, so I thought this surely couldn't be right.So, here's what I did:1: I completely drained the battery by using it to charge my laptop (so that it would drain faster.)2: After it stopped charging my laptop and displayed 0%, I plugged it into a 45W wall charger.3: I kept checking the display on the power bank to see if I noticed anything... odd.4: Once the power bank hit 80%, it started climbing REALLY fast, but the incoming wattage stayed the same. That certainly seemed odd.5: After the display showed 100%, I left it plugged in for another 30 minutes. (Also, after the first 10 minutes passed, it still felt warm, like it was actually still charging.)6: After 30 minutes, the power bank felt cooler to the touch, so I suspect it finally stopped charging.7: When my phone was running low again, I charged it with the power bank again, and the display seems MUCH more accurate now (after charging my phone 30%, the power bank's display shows 95% remaining, which seems more realistic.)Review:I wanted a power bank that was capable of giving my laptop a quick boost without being a bulky monstrosity. I was debating between this one and the Anker 737, and ultimately decided on this one mostly due to it being a little more compact (with slightly less capacity, of course) and also liked the idea that I could charge two supported devices at a full 100W each at the same time, if needed.First impressions are good. It's compact enough to stow away easily in my backpack while also providing a generous 20,000mAh, which is plenty for my needs. It comes with a nice, soft travel pouch, and a USB-C to USB-C cable that's rated for 140W. It does NOT come with its own charging brick (I knew this ahead of time, but it's something to be aware of.) I used an Anker 65W charger to charge this up, and it did pull the full 65W and charged up nice and quick.The bottom of the power bank is actually magnetic. I accidentally discovered this when I set it down on my metal filing cabinet. This is likely to keep it attached to the optional charging dock, so that's good to know.The display is nice and informative. It'll show more information with multiple button presses, and also let's you change some settings (screen timeout, brightness.)I tested this out on my laptop - an Asus ROG Zephyrus G15. Its USB-C ports are rated for 100W max, and the display on the power bank was showing between 97 and 98 Watts, so for me, it worked as expected. With my phone (a OnePlus 7 Pro) it was only pulling about 8 Watts, but this phone uses a proprietary charging standard and only charges at full speed with its own branded charging brick. Charging speed will depend on your device, so if it uses a different standard or anything, you might not see the full 100 Watts. I'd check your devices' specs before purchasing.Being 20,000mAh, this probably won't fully charge my laptop (I also knew this ahead of time) but it's plenty for a quick boost when I need it. I'm a frequent road-tripper and find myself off the grid often, so this will be a great travel companion that doesn't take up too much space in my bag.(Side note: I also dig the reference to a fantastic multiverse movie in Anker's marketing here.)

Waited about a year to review. I don't know what these one star reviews are about. Uneducated on how batteries work perhaps. I travel a lot. This thing has been all over the world with me. Charges my Macbook Pro, phones and countless devices just fine. The capacity is the capacity. Nothing is going to charge your phone 30 times without a recharge so if you expect that you are unschooled.

My battery failed after a dozen or so charge cycles at which point the battery would, when fully charged, just start to drain itself while nothing is plugged in. Within about 24 hours the battery, sitting on a table with nothing connected would be fully depleted.I contacted customer support for troubleshooting and resolution, they provided solutions that were ignorant of the actual issue, suggesting that I am dumb enough to have left something plugged in and then complain that the battery is being deletedThen they finally agree to do a warranty replacement. They give me a return shipping label for USPS priority mail. When I go to drop off the return package, they reject it saying that I cannot use this shipping label to ship lithium ion batteries. I update customer support about this, they tell me to go try more USPS locations in hopes that someone will accept it. I spend hours driving around multiple USPS branches, no one will accept it. They then tell me to try another shipping company and pay with my own money and they will reimburse me later. I once again drive for hours looking for a UPS or FEDEX location that will accept the package. In the email, they mock me saying "good luck" as though the task of getting this package to them is some sort of prank. Finally after arguing with a FedEx shipping center employee, they accept the package.They now refuse to give me a tracking number for the replacement item, saying it's too early but also saying in the same email that the replacement had already been "released." I also have not received any indication of confirmation of a pending refund.Terrible experience. Don't deal with customer support if you have an issue, just return the item as defective. They will make it as hard as possible for you to get a solution. Read to the reviews, this is not on par with the Anker quality that I have known.

Awesome power bank. Love that it shows output and input power. Has a trickle charge setting for devices that don't draw much and may not otherwise activate the power bank (Like airpods etc)Pros: great size for capacity, speeds, screen read out, costCons: device seems to say 100% charged yet continued to draw 18 watts for some time until it dropped off. This tells me it's still charging despite it saying 100%.Tl;dr: great power bank. Leave it charging even after it says 100%, it's not fully charged yet.4.5/5 stars because of that little quirkI also wish, if they weren't gonna include Bluetooth, at least let us limit the output and input power.
