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

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.

When you plug it in to charge the Power Bank, it just sits there for a while doing nothing. The power level remains unchanged and you wonder if something is wrong, you got a defective piece or what, is the charging cable the appropriate one, etc. etc. But, then after some time, (havent timed it yet) it suddenly starts charging and then it charges pretty fast. The product is sleek and all and works well, but it pretty much uses up all its charge to charge my mobile fully from say 10%. I thought I would get at least two charge cycles but, this was a little disappointing. But, otherwise the device looks great and works fine.

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.

Working strong from 1 yr

It came partly faulty (the normal USB doesn't charge) and I noticed too late to give it back. Still, the customer service was very helpful and even offered me a full refund. So definitely a trustworthy company

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

Good product… using it for both laptop and mobile charging… however price is too high

I am satisfied with the product.

Powerful and durable, very good quality

Excellent power pack. Have used it on my travels and it will charge two samsung Galaxy S25 F phones fully no problem. Separately it will also charge one Samsung Galaxy S10 FE with enough charge left to almost charge a phone. This product is great for long trips. I use google maps a lot and found it would drain my battery down towards late afternoon. Just plug this pack in and charge on the go. The attached charging cable is a great feature and stows neatly into the batteries side, however it could be a little longer. It's a little heavy but to get the extra juice requires the extra weight. I've carried it in my backpack and it's not noticeable for me. Overall great product if you're looking for that extra charge out of one battery pack.

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.

تحفة وعملي جدا

Ürünü 01.08 2026 tarihinde satın aldım. Paketleme ve kargo hızı çok iyi. Malum 20.000'lik olunca biraz ağırlığı var tabii ki... Biz Samsung A25 ve Redmi 12 Pro telefonları birer kere şarj ettik. Powerbank %50 kaldı. Ben memnun kaldım. Lakin üzerinde ki sabit kablosuyla hızlı şarj yapmıyor. Tekefonlarımızın kendi kablosunu kullandık öyle daha hızlı şarj oldu. Zaten üzerinde ki Kablonun boyu kısa... bu konu almayı düşünenler için bir sorun teşkil eder mi bilemedim. Bana soracak olursanız tavsiye ederim.
