Power Bank, 20,000mAh Travel Essential, Built-in USB-C Cable | 1 USB-C and 1 USB-A port, for MacBook Pro/Air, iPhone 17/16/15/14, Samsung, Switch and more

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.

> **5/5 ⭐** – The Anker 20,000mAh Power Bank delivers reliable, fast charging with enough capacity to recharge a smartphone multiple times. It's well-built, easy to carry, and perfect for travel, work, or emergencies. A dependable battery pack that offers excellent performance and value.

Anker Power Bank, 20,000mAh Portable Charger with Built-in USB-C Cable, 87W Max Fast Charging Battery Pack 1st charge of the battery pack. 15% charged (this is out of the box) 50% charged @ 28mins 75% charged @ 45 mins 99% charged @ 65mins 100% 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/0aXRbjlW Charging 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.

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.

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.

Amazing power bank, so good I got two! I've had the black one for about a year now, and it's shown no signs of diminishing health etc. For me it is fine, but it is on the heavier side of power banks, and probably not the most efficient for someone who needs to charge there phones whilst using them out and about, and if you are you need your own cable as the built in cable isn't long enough. It's completely useable however and i would recommend it for longer trips without chargers, as it is able to charge my 5000 mAh phone 3.25-3.36 times (my own testing) from one charge. It does get a little warm, but not anything concerning. My only real problem lies in it's design however, as it does get scratched up quite easily, so handle with care if you want yours to stay pristine. Also, the white one's display is far harder to read, and the text on the back sticks out a lot, so I would recommend the black one. I have given it five stars as it can charge my phone extremely quickly, as it can input and output 65w from one usb-c port, which allows the pack to charge fully in under 2 hours, which is very convenient.

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.

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.

Buen power bank. No se calienta, carga rápido y tiene buena capacidad. Lógicamente, es pesado, pero es normal para tener esas prestaciones. Muy práctico que tenga su propio cable usb-c incorporado.

Excellent

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.

Very quick charger, not so quick charging itself.
