Power Bank, 20,000mAh Travel Essential, Built-in USB-C Cable

Anker Power Bank, 20,000mAh Portable Charger with Built-in USB-C Cable, 87W Max Fast Charging Battery Pack1st charge of the battery pack.15% charged (this is out of the box)50% charged @ 28mins75% charged @ 45 mins99% charged @ 65mins100% charged @ 87 mins (1hr27m)I am unsure why the final 1% took over 20 minutes, perhaps this is because it was its first full charge. I will update this review in the future if this (relatively minor issue) persists.***UPDATE : This was a one off, and has not occurred since the first charge***However, I am very happy to know it takes around 1hr to ‘fully’ charge, so any last minute trips will be covered with a quick blast of charging.I should point out the charger I was using for this is the Amazon Basics 63w wall charger (model-B087S3HZ3P). https://amzn.eu/d/0aXRbjlWCharging my iPhone 16 pro max using the inbuilt USB-C cable.* = percentage remaining on battery pack.10% charged (starting point)25% charged @ 7mins *95%*50% charged @ 22 mins *86%*75% charged @ 45 mins *77%*100% charged @ 110 mins (1hr 50m) *66%*As expected the last quarter charged considerably slower (especially the final 10%). However, a 40% increase in the first 20mins is phenomenal. It seems perfectly compatible with my phone. And the above percentages would indicate I could charge my phone to 75% up to four times.The battery pack weighs 426g according to my kitchen scales, compared to my iPhone 16pro max which weighs 277g (including case). Although I would not exactly describe it as light, it’s certainly not intrusive when in a pocket and would sit unnoticed in a bag. The size is slightly smaller than my iPhone and roughly twice the thickness.The quality is what I’ve come to expect from Anker. It feels solid and very well made with no creaks when pushing on the corners. The attached USB-C (IQ3) cable feels like it would take considerable and deliberate effort to damage it, and it neatly tucks away when not in use. The cable is approximately 16cms (6.5 inches) in length, which is relatively short and would require the user to either hold the pack whilst using a phone or to prop their device next to the battery pack, I would recommend using your own (much longer cable) if you wish to use your phone whilst charging. However always having an inbuilt emergency cable is a huge positive, and its length shouldn’t detract from the convenience this provides. It is also an in/out, so you could plug this in to a power adapter to charge the battery pack.The two ports ontop of the device are one USB-A (IQ2) and one USB-C (IQ3). The USB-C acts as an in/out port so this is where you would plug in a cable to charge (you can also use the built in cable to charge the powerbank).The black coloured version is prone to fingerprint marks, which admittedly are easy to wipe off and remove.The display only shows the remaining battery percentage, it is nice and bright and easy to read.Overall I am extremely impressed with this charger and I highly recommend it.

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.

Excellent bit of kit. It is heavier than my other Anker power bank and quite a bit bigger, but it feels very sturdy. Nice clear power percentage icon so you can see immediately how much power it has left. I charged my phone from completely flat as a test to see how much power it would use and it used just a little over 20%, so it's good for at least 4 full charges of a Samsung S26. Built in power cable is handy and tucks away really neatly, so it won't snag or catch on anything in a bag and you won't lose the lead. It's compatible with my S26, my partners S23 and my Galaxy Tab S11. It charges up quite quickly as well, much quicker than my old one. It wouldn't fit in my coat pocket as easily like my old one, so that's something to bear in mind if you want to carry it with you, it would be better in a bag as it is quite big. But very impressed for the price.

Power Bank is a solid and reliable charger with plenty of battery capacity for everyday use or travel. It feels well built, charges devices quickly, and does exactly what you need. The only downside is that it’s a little bulky, but that’s expected with a battery this size.

My old Anker battery finally gave in after 8 whole years of usage, and I bought this one to replace it.This thing is definitely not small, I'd say it's around the size of 3 or 4 large phones stacked on top of each other (like an iPhone 15 pro max), however this size is justified as its quite a high capacity and fast charger. If you're looking for something to fit in your pocket, this product probably isn't it.Despite it's large size, this product definitely doesn't look bad, it's matte black and has a display on it with it's battery life as a percentage.This battery is very fast at charging, it can charge my Samsung at "super fast charging" which I think should be 45w, and it should be able to charge my laptop at 65W. For performance, this thing will keep up with most things you'll need to charge. As well as this, if you have a fast charger, the battery itself will fill up about 2 hours, which was a massive improvement over my last battery pack.The built in usb c charger is a double edged sword, it very conviently fits into the side of the battery and can be used to power device, as well as refill the battery itself. However, since it's built into the battery if it ever breaks, snaps or is damaged, you can't just buy a new cable as far as I'm aware. However you can still fill it up from the usb c port on the top so it's not end all be all.This product is very good if you need to power small or medium devices for a long time, or if you're like me and constantly forget to charge up or bring your charger in for your laptop for lectures or work. If you want a product for just your phone, there are probably smaller products by Anker or another companies that will be more convenient, but if you're fine with tossing this in your bag or a large pocket then you won't be disappointed with this product.

This is a good quality charger from a respected brand. Unlike some cheaper ones I have bought in the past, this one has been totally reliable. The captive cable is more useful than I expected (always available if you forget to bring a charging cable) - I rarely use anything except usb-c these days. It charges quickly and holds the charge well. The only drawback I’ve found is that you cannot charge the power bank and charge a device from the power bank at the same time (which would be helpful if there is only one charge port available, especially if it’s a slow one), but that’s a very minor point.

Received this today but so impressed I wanted to leave a review now as I am so pleased with it.Its a solid Powerbank, definitely heavy for 20000mah (but I like that) still ok to travel with. My previous Powerbank was 27000 mah from Charmast which ended up splitting and expanding after 4-5 years of use, took forever to charge it and to charge iphone 13 and 16 pros.This one looks so neat I feel like I have had a new phone, slight mark on the right near the display but am ok with that. I have also bought an Anker lead and power adaptor (see photos).I put the powerbank on (first) charge from 5% which is what it was when I received it, total time to fully charge from 5% to 100% was 1hr 36 mins, didn’t seem to slow down at all even at the 90% -100%, maybe the Anker 65 watt adaptor and the Anker 100 watt usb c to usb c played a role, not sure. Powerbank never got hot just warm and its 27 degrees here atm. Never had Anker products before but you have got an extra fan now. Will update the review in a months time.

So I bought this after a bit of research for a powerbank for a festival. Bit hesitant at first if it was going to last the 5 days. After a testing of the weekend I'm really happy with it.So charging to 100% can take a while, but once charged. I've used it to charge a Google Pixel 8 4 times so far from 20% to 80% using around 20%(ish) of the battery pack each time. Though I have noticed at times, the percentage left on the battery has increased a little. So might not have used nearly as much as I though.The size and weight of it is bigger and heavy than I would have thought but for battery storage it does mean it lasts. The cable attached I haven't used but being able to plug in a type c and a USB has mean it's easy to use with other cables. The display is handy to know the percentage left while not being too big and it's handy to put into most bags without it taking up too much room.

Powerful and durable, very good quality

Excelente produto. Carrega rápido e rende várias cargas no meu celular.

Is a great item ! As described.

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

Good quality, very satisfied
