Anker PowerCore III 19,200mAh Huge Cell Capacity 45W Power Delivery Portable Charger for MacBook Air 2020, iPad Pro 11, iPhone 11/11 Pro/XS Max/X / 8, Samsung and More

Update 2023-03-16:I had used this charger many times and it always came through, it holds charge when not used, it delivers when needed. I used it recently for charging outdoors camera and it barely lost almost 1 bar out of 4. As opposed to another portable battery when used for the same purpose, that other charger used 3 of 4 bars.I appreciate this particular portable battery and I don't see another model which would fit me as well as this one.Dual USB-A output, what I use most.USB-C input or output -- that's how I charge this unit, and while I don't use USB-C output much at all, I know there will be times.----------------------------------------Original review 2021-07-14:There are so many choices out there, digital readout, many inputs, outputs, large capacity, low weight.My Anker charger with 10,000mAh just lost full powering ability. I bought it in 2015, so 6 years of service (in the car mostly) is a well deserved retirement age in the world of electronics.Important to me are dual USB-A outputs, along with a USB-C output (maybe i will use it for MacBook, it doesn't hurt to have options), and USB-C input for faster charging of this unit from the wall. (4 hours is acceptable to me from empty to full)This charger is only 2 inches loner, fraction of an inch wider and about 1/4 inch taller, but it has double the capacity. More importantly, it comes from a family of great Anker products, has Anker name of warranty behind it, and from my past experience, they answer emails, follow up, and make sure when something does go wrong, to make it right.Common issues with other products from other companies:1) On/Off switch which you have to press to ON to be able to use a connected device. And you have to press it to ON after some time, or possibly touch it accidentally and turn off charging... why? This device has a button to see 4 levels of charge level, 25, 50, 75, 100. That's all you need. You will not see a 78% or 23% as a digital readout, but you will get a dependable device which works as it should, has specs that can be trusted, and is warrantied for probably even longer than advertised. I have read and experienced Anker going beyond their documented terms.2) Capacity. Other products' reviewers comment how the numbers can be inflated, not with Anker. If a little known company claims same capacity as twice as big and heavy Anker product, would you trust those claims? To work now, and in the future?Buy a product at a discounted (it appears) prices elsewhere, and then buy something later that actually works, or buy Anker, that's the conclusion I came to recently after 2 hours of doing my homework, and it is consistent with my past purchases.Anker just works.In the picture is my 6 year old 10,000mAh charger, and on the right the new one, double the charge, feels like double the weight and a little more height and width.

The first thing I like about this unit is that it can be charged in about 2 hours if you use a high wattage wall plug and the correct cable. I used the Anker 45 watt Nano II. I used an Anker Power Line III. You must use high end Power Delivery (PD) hardware to get such speed.As for charging my Pixel 3, the unit performs extremely well. I do not know if the Pixel has the latest PD, but it charges much faster than with my previous power bank, A Ravpower unit with an "intelligent" USB-A outlet and a USB-C input/output outlet. That said, I did not compare the USB-Cs with the same cord, and my old Anker cord does not support PD. However, the old unit could only be quickly charged with Quick Charge 3, and I was not going to experiment with old technology on an old power bank.

I'm a long time Anker user and after many years with an old 13k mAh battery I decided to upgrade to get more capacity as well as faster charging.From one long weekend flight/vacation, this battery performed more or less as expected, but I docked a point for the following reasons.1. Fast charging/PD is only available on the USB-C port (if this is a limitation of USB-A then I apologize and will redact if someone let's me know).2. Given Anker is a popular cable manufacturer (again, I use their cables every day at home and at the office), I was surprised to find out the included USB-C cable doesn't seat in my phone port securely (Pixel 3). It's almost as if the male end was ~1mm too short so I could only maintain a charging state if I held it in place with positive pressure into the phone. I discovered this while taking a flight/short vacation and luckily I had a backup cable with me to use during my trip, but it was a USB-A to micro USB + micro to USB-C adapter so I was stuck with slow charging all weekend.3. Very minor and purely preferential, but I also wish the PD port was in the center, between the USB-A ports, so I could cinch the travel bag closed without putting pressure on the USB-C cable/port.That said, I don't regret my purchase, but I do wish Anker would've included a decent cable with it, otherwise it's just a waste of materials and should've been omitted.Update, 01/03/2021: I've gotten a Pixel 6 and tried the cable again and it seems to seat well. It also triggered the adaptive charging mode which seems to trickle charging to finish topping off the device at the time of the next alarm. Since the cable connectivity issue seems to be with my Pixel 3 I've updated this review from 4 to 5 stars. Sorry I doubted you, Anker!

During its life, it was a champion. Powerful enough to charge a steam deck as if plugged into a wall. Enough to offset most small laptop battery drain/ extend battery life notably. Easily charge multiple smaller devices quickly. Used for domestic and international travel, no remarks from security. Definitely a good size.However, the last few months have had issues getting it to turn on and taking a charge. Discharges quickly if able to power up.Just today. No charge whatsoever and indicators no longer light up. Maybe there's a fix. Also, maybe a good time to look for an upgrade.7/2022 to 9/2024.I will say I'm dismayed at its death, but not entirely disappointed. I would've liked another year (or 10?) but is that asking too much?

Anker makes great products and this is no exception. I use these charging cells for work and also when on the boat or baseball field and scoring with iPad. Their cables are also top notch and handle the rigors of life well. My boys “borrow” my cables routinely due to the quality.The battery does take a bit of time to charge, so make certain you get a strong enough AC charger. I too use Anker chargers and find them very reliable as well!
