In depth review – Anker Power Bank, 20,000mAh, 87w fast charging
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.

Great in/out speeds, great capacity efficiency and perfect size (black one was used for a year)
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.

Best powerbank I’ve ever owned
This is the he best powerbank I’ve owned by some distance.It’s charge is absolutely rapid 👍It can charge my phone several times over 👍I’ve used it to run a cine dslr on a gimbal👍Display is clear as a bell 👍So, as you can see, pretty versatile, and easy enough to sling in a backpack to carry around. It’s not the smallest thing, half the width of a paperback and about as thick.But it’s bloody quick and holds charge well.

A powerful and convenient charger that’s become my everyday essential.
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.

Doet wat het moet doen zonder toeters en bellen. Ik ken dit merk al zo’n jaar of 15 en nooit teleurgesteld. Ik gebruik de powerbank om smartphones en dashcams van stroom te voorzien. Heb er nu drie waarvan er één deel uitmaakt van m’n noodpakket. De powerbank zelf opladen duurt uiteraard een paar uur, maar viel niet tegen. Ik laad powerbanks alleen de eerste keer tot 100 procent, de keren daarna altijd 80 of 85 procent.Bezorging via DHL was trouwens mooi op tijd.
