Review: 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 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 desertcart 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.
Review: 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.

## Questions & Answers

**Q: Why is my power bank providing fewer charges than expected?**
A: The capacity reduction during charging is due to a 30% to 45% energy loss in the battery cells and conversion circuitry. Therefore, a fully charged Anker A1383 Power Bank (PowerCore 20K) offers an estimated 11,000mAh to14,000mAh to power devices.

**Q: How can I estimate the number of charges for my device?**
A: To estimate charging cycles, use this formula (Power Bank Capacity × 0.65) ÷ Device Battery Capacity ≈ Number of Charges. For instance, charging a 3,000mAh device using a 20,000mAh power bank would offer approximately 4.33 charges.

**Q: How long does it take for the power bank to recharge?**
A: It depends on the charger's power and the ambient temperature. The A1383 model, when using a 30W PD charger at 77°F (25°C), takes about 4.5 hours to recharge.

### ⭐⭐⭐⭐⭐ Best powerbank I've ever owned
*by D***H on 6 May 2026*

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.
