Anker Power Bank, 20,000mAh Portable Charger with 22.5W Max Fast Charging, 2 USB-A, 1 USB-C for iPhone 16/15/14/13/12 Series, Samsung, iPad Pro, AirPods, Apple Watch, and MoreClimatePartner certified

This Anker power bank works amazingly. When it is fully charged, it lasts for a long time. I haven't really tested it out to see how long it lasts. In what I have used it for is 5 continuous hours. After 5 hours, I see that there is 3 out of the 4 LED lights left on. I've had this for 2 years now and it lasts. In terms of its size it's long, but not that bulky. It is easy to travel with. Once you plug in it starts automatically to charge your device. In case it doesn't you can just push the button to start charging your device. The portable charger has 2 USB-A outlets and 1 USB-C outlet. It is a great portable charger. Probably the best portable charger I've owned.

Fantastic portable power source. Charges my phone quickly and multiple times between charges. It's heavy, but that's to be expected given the power it packs. It's larger than my phone, but worth the weight!

I first bought one of these a year ago while traveling to New York. It has been amazing and I’ve used it almost every day since. I use it for charging my phone when I get home from work, and I’ve also used it while camping and it powers fans and lights and also charges my phone and lasts all night no problem. It works with any cable I’ve used so far. Does not get hot at all while charging, maybe just a little. It is big naturally due to the capacity but it being slim and the plastic being sort of slippery makes it fit anywhere. I love it so I bought another one. And I will probably get more.

It's not often that a product exceeds expectations to the point where it deserves a rating beyond the standard 5 stars, but the Anker Power Bank 20K has done just that. With its remarkable performance, sleek design, and user-friendly features, it has earned a well-deserved 6-star rating in my book.Durable Design with a Modern Twist:As someone who has owned a previous Anker power bank, I was already acquainted with the brand's commitment to quality. However, this updated design takes the cake. Its build exudes durability, ensuring that it can withstand the rigors of travel and daily use. The sleek white finish is not only aesthetically pleasing but also resistant to wear and tear.Dual USB Ports and USB-C Fast Charging:The inclusion of two USB ports is a game-changer. It allows for the simultaneous charging of multiple devices, making it an ideal companion for those who travel with various gadgets. The USB-C fast charging capability is a notable upgrade, ensuring that your devices are powered up swiftly and efficiently.User-Friendly Charging Status Indicator:Reading the charging status has never been easier. The clear and intuitive indicator lights keep you informed about the power bank's remaining charge, eliminating any guesswork. This feature is a testament to Anker's commitment to user convenience.Impressive Charging Capacity:The true strength of this power bank lies in its capacity. During a full charge, it provides enough power to recharge your laptop once and your cell phone up to four times. This level of versatility is particularly valuable for those who are constantly on the go, ensuring you stay connected without interruption.Quick Shipping and Unmatched Quality:Anker's reputation for quality and reliability is well-deserved. Your expectations are not only met but exceeded. Shipping is swift, and the product arrives exactly as described, reinforcing the trust that Anker has built among its customers.

I have a couple of low-energy USB devices I'm travelling with that seem to work absolutely perfect with. It only came charged with most of the first dot, so I spent a significant part of the day getting it to part of the third dot using a standard USB plug before remembering I have a Chromebook charger that operates as a superfast charger that finally got it from somewhere in 2 dots to somewhere in 3 dots.I haven't been able to dispense with the purpose of the external battery long enough in the two days I've had it to see how long it takes to get it to full charge but I also haven't killed it with the use. That said, getting the charge from somewhere in flashing third dot down to somewhere in flashing second dot with my two low-energy devices took about 15 hours.I tried using it to charge my Note 2020 Ultra and it was very slow, even using the cord I use from the Chromebook fast charger, which when using the Chromebook base only takes 25 minutes to get from 15% to 100%. So, I threw it back on the regular charger so I could charge my phone and forgot about it for about 10 hours, and it remained on the second dot. For about an hour before I needed it to utilize the low-energy devices, it charged and got from wherever it was on the second dot to somewhere on the third dot. The devices have been going about 3 hours now and it is still on the 3rd dot.It's really good for the project I'm working on with the low-energy devices I'm using. I don't know how long I could get away with using them both at max power but if it's at least a few days I won't have to update to talk about how or whether or if this was a mistake *for that purpose* since that was the purpose for which I bought it. However, if you have a high-usage phone that is fast-charge capable, this may not be the PowerBank for you. I wasn't using my phone (which is always on Power-Saving mode) while it was charging, but it only went up, maybe, 10% (I don't remember exactly but it wasn't very impressive) in almost 30 minutes.I love Anker products and almost have never had problems with it. And the ONE time I did YEARS ago: they made it right as soon as I made it known with a very quick replacement. This one just isn't the giant one I did buy to charge my phone--which also does do a good job of charging my mom's iPad, Nord work phone, and S22 Ultra. The sale, small size, and promise of high-voltage USBs is what I bought this for knowing I needed it to operate at a low-level plug in a more portable way. So far, it's fulfilled that perfectly and for that purpose I have no complaints =)

Just buy it, seriously!!! It is the best power bank I have ever purchase. Let’s say I own several. This charger last a long time. I’m so happy with my purchase. it is a little heavier than I expected but the performance is exceptional.

Like always Anker builds good quality items and the capacity is more than enough for 1-2 days of use with its fast charging speed.
