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 longIt 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 productComing 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 minutesI 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 0/5OLD REVIEW(1/5):This power bank does not keep its promisesThe description page says it charges in 1.5 hour with a 65W chargerReality: It took 6-7 hours for it to chargeAnd the support is the worstThey ask for details and they say they will replace and after 2 days they keep asking for invoice or they don't reply at allI had to waste another 30 minutes with Amazon support to get back my refundI am not going to buy an Anker product again and I would suggest you to do the sameThey are full of misleading advertising and incompetent support

Met all my expectations - Value for money - Easy functionality - for Travel it's little heavy- Design is good but need a cover, because gets slippery due to its weight.

Sleek. Portable. Compatible with quick charging for most devices needing upto 60W. Tested with Moto, Apple , Samsung. The battery level indicator and the cables are huge plus. Overall its solid and much sturdier than cheaper alternatives.

Good

Very good charger. Kilter bulky but work well. It can charge my MacBook Pro as well (do slow charge but helpful when need in emergency).

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- LaptopCase1:- 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 inefficiencyNote:- same apps ,same brightness levels was being used to test the product.Test 2:- MobileCase 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 fusionI 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.
