Anker Power Bank, 20,000mAh with Built-in USB-C Cable, 87W Max Fast Charging (PowerCore 20K for Laptop) Lenovo, HP, Dell, Microsoft, MacBook, iPad, iPhone, Apple Watches, Samsung and More - Black

UPDATED REVIEW: Turns out I was using a charger which did not provide enough input for it to charge quickly. Turns out my charger provided 65W output only to my phone. If I charged with other devices, it was only 10W power source. That is why it took so long It is clear to me from this that the customer support is not trained or does not know how the product functions. Customer service I will give a 0/5. They do not help you or provide any advice. They keep delaying replying. They will only tell they will help you to replace it and dont reply after that. The customer service reps should be trained on the product Coming to the product it is excellent. - I bought a 65Watt PD charger and it went from 24% to 100% in 45 minutes. Excellent stuff. Fast charging is very useful for me when I am hiking and get power sources sparingly like once in 2 days and I don't have to spend 7-8 hours in a hotel for charging the powerbank lol - It charged my laptop from 50% to 94% in 48 minutes I am very happy with Anker powerbank. For the product I give it a 5/5. I am very disappointed with the customer support which is a 0/5 OLD REVIEW(1/5): This power bank does not keep its promises The description page says it charges in 1.5 hour with a 65W charger Reality: It took 6-7 hours for it to charge And the support is the worst They ask for details and they say they will replace and after 2 days they keep asking for invoice or they don't reply at all I had to waste another 30 minutes with Amazon support to get back my refund I am not going to buy an Anker product again and I would suggest you to do the same They are full of misleading advertising and incompetent support

A large capacity (20,000 mAh) Power Bank is an excellent (2nd) buy for me. It meets my charging requirement of outdoor/in travel use of my 17" laptop, two cell phones, and a mini fan. 87 W power is more than adequate. Does not heat up at all. I found it to be quite sturdy and handy. It has a long backup after a full charge, a really fast charger at that. A short charging cable with a USB-C connector reduces line losses.

Its an awesome powerbank. It handles my macbook as well. During emergencies it can keep my laptop alive for quite a while. And the inbuilt usb c is just one of those features i didnt know was actually really helpful.

Used it only once. Seems to be a good product. Need multiple usage to give a realistic evaluation. Hence the 4 star rating.

Great charging capabilities.... Supports fast charging in most of the devices. Colour is neutral black. U can charge any device... without any hesitation (ofc it has to be type C supported)... Compact...but heavy obviously it's a 20000mAH... If someone asks why should I buy Anker when I can get other brands for less prices...yes u can get....but Anker is a premium international brand...and the features it's providing...for me it's Value for money.

This power bank is a really good option for long travels. What makes it interesting is the C-type cable option. It is also pocket friendly power bank and also give the percentage of the charge available so that also let you know of you need to charge the power bank or not.

While the power bank took only 1-1.5 to charge from 0 to 100% which is good. But it's performance is the main concern. It claimed to charge macbook 1.2 times and mobile like s23 ultra 3 times. Which is wrong:- Test1- Laptop Case1:- When i was using my laptop(with battery currently being 22% and laptop was being used simultaneously) it reached 87% and the power Bank completely drained from 100 to 0. Failed 👎👎 Case 2:- when i charged my laptop again when it was in use . It was at 25% , but this time the power bank charged it completely to 100% and the powerbank drained from 100 to 0. Failed 👎👎 Case 3:- when the laptop was closed (sleep mode) it charged my laptop from 6 to 100 within 2 hours but the battery remaining only 7 percent on the power bank. So it can't charge 1.2 times. Failed 👎👎 Case 4:- again i ran this test, and now it drained completly under the same conditions. Failed 👎👎 My laptop is lenovo ideapad 5 which has smaller battery than the macbook advertised by the company. So the powerbank should charge it more than 1 times. But in 1 time only, it is completely drained and leaving only 7% So you can see the inefficiency Note:- same apps ,same brightness levels was being used to test the product. Test 2:- Mobile Case 1:- it took 8.5 hours to charge my moto g54 from 0 to 100 and in this time range the power bank drained 45%. The efficient capacity of any Powerbank is 80 to 85% meaning that the actual capacity of any company's powerbank will be less than advertised. So if i consider 85 percent of efficiency then the power bank has 17000 mah. My phone has 6000mah of battery . So 45 percent of 17000 is 7650 mah. Meaning it took 1650 mah more to charge my mobile and it took 8 hours which is very long. Note:- This mobile supports 33 watt fast charging and it takes only 2 hours to charge it from the stock charger provided by the company. So in this case it is failed 👎👎 Case 2:- Moto edge 50 fusion I charged my mobile from 0 to 100 and it took 50 percent of the power bank's battery. Which is the highest drain i have noticed till now in any power bank. So 50% of 17000 is 8500. It took 3500 mah more than my phones actual capacity which means that something is wrong with the internals of this power bank. Again ran the same test, now it took 45 percent. While in this case it took only 1.5 hours to completely charge my device which is a thumbs up 👍 Note:- My mobile has 68 watt fast charging and it has 5000 mah of battery. It takes only 1.2-1.5 hours to charge my device from the stock charger provided by the company. So the efficiency of this power bank is very poor. In this case also failed 👎👎 While i have used many anker products in the past, some of them like my soundcore life note purchased in 2020 is still working fabulously and it is now also providing me 8 hours of playback time. But i cant recommend this powerbank.👎 Thank you for reading the post. As no one on yt is talking in this detail about this power bank

Works very well, and the built in cable fast charges most phones! Would highly recommend though a bit on the expensive side.

Powerful and durable, very good quality

I've owned a lot of power banks over the years, but they all had the same problem: they were useless if I forgot to bring the right cable. This Anker 20,000mAh power bank completely solves that. The built-in USB-C cable is an absolute game-changer. It tucks away neatly into the side of the unit, and it means I can just grab the power bank and go, knowing I have everything I need to charge my phone. The capacity is massive. 20,000mAh is enough to charge my phone (a Samsung Galaxy) at least three to four times from empty, with some juice still left over. It's perfect for a long weekend away, a festival, or just for those busy days when I'm away from a wall socket for a long time. It also charges my tablet and headphones without any issues. Beyond the built-in cable, it's also got a standard USB-C port (which works as both an input to charge the power bank and an output) and a USB-A port, so you still have the flexibility to charge older devices or help out a friend who has a different type of phone. The charging speed from the built-in cable is great, supporting fast charging for my phone. In terms of design, it's about what you'd expect for a high-capacity bank – it's got some heft to it, but it's slim enough to slide into a backpack or a large coat pocket without being too obtrusive. There's also a handy little button on the side with a circular display that shows you the exact percentage of battery remaining, which is much better than the vague four-dot systems on older models. Verdict: This is pretty much the perfect power bank for anyone with a modern USB-C phone. The combination of huge capacity, multiple ports, and the sheer convenience of the integrated cable makes it a top-tier product. It’s reliable, well-built, and has replaced all my other portable chargers.

Melhor compra. Salvando meu dia, infelizmente depois de 1 ano a bateria do celular ja nao dura mais nem 12h continuas de uso intenso. O único detalhe do carregador, que de fato da carga completa rapidamente, e cumpre o que promete, é o peso do equipamento.

Really liked this power bank. I have been using it with my Samsung S24 Ultra, and it easily gives me more than two full charges. The charging speed and overall performance are very good. I mainly use it along with my Xiaomi Pad 6 tablet and phone, and this single setup is enough for me to comfortably manage for almost two days without worrying about power. Compact, easy to carry, and very reliable for daily use. I have been using it regularly since purchase and have not faced any issues so far. Definitely a good buy for travel and everyday use.
