Why is my power bank providing fewer charges than expected?
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 to14000mAh to power devices.
How can I estimate the number of charges for my device?
To estimate charging cycles, use this formula:
(Power Bank Capacity x 0.65) + Device Battery Capacity ≈ Numberof Charges
For instance, charging a 3,500mAh device using a 20,000mAh povver bank would offer approximately 3.8 charges
How long does it take for the power bank to recharge?
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.

Loving this portable charger for the past nine months! I don’t leave home without it.
I have been a proud owner of my Anker portable charger for nine months. It mainly lives in my EDC bag, but has also gotten used in the home when my youngest child is using her phone but not near an electrical outlet and her battery is low. It came in handy for my teen who needed to have a backup charging source with her for computer-based standardized testing. I feel good knowing that if there’s a power outage, I have a reliable charger for my Android phone, MacBook, and Bose headphones (when in trickle charge mode for low current devices). And, when we go out of town…this charger ALWAYS tags along.I love the built-in charging cable—that’s a gold feature in itself. I have a few other chargers, but this is my primary for that reason. If something were to happen to it, I would purchase it again. It recharges quickly with my 45W charging block using either the built-in cable or a separate USB-C cable. I am considering buying both of my children one for Christmas this year to replace their Anker chargers (that don’t have a built-in cable nor provide as many charges).What’s not to love? It’s compatible with my devices, provides me with multiple charges, it’s reliable, and I love the Anker quality.

Best charger I have ever owned!
This is the best portable charger I have ever owned. I bought this one mainly for charging my Switch 2 on the go as the battery life is not great on that one. This works perfectly for keeping it charged and able to play whenever I want.We also took it to Florida on vacation with us. It is a bit heavier than my previous chargers, so my wife made me carry it. But when the phones need a quick charge, this did the trick. Very happy with this purchase and would highly recommend for anyone looking for a charger for new devices. Especially, the Switch 2!!

Amazing!
A bit heavy, but completely worth it. Recently bought this for an upcoming trip; however, I ended up using it before that as the power went out. I was able to charge my devices (two iPhones, 1 MacBook, and an iPad Air) quickly and had no problems re-charging the bank after. I like that it shows the percentage and really holds its charge when not in use. I’m a huge Anker fan —I use many of their products, and they always do a fantastic job!

Fast and powerful
Charges phones quickly. Powerful enough that laptop doesn’t think it’s a power bank (no slow charger warning)Provides just about 2 full laptop charges, or 5-6 cell phone charges. Super useful and reliable. Attached USB-c output cable is very convenient.

Fast Charging, and TSA Aircraft Carry On Compliant Item
This Powerbank is Awsome..Pass Thru Charging…Charged an Older Ipad at 30% To 97% In about 40 minutes!! This kind of performance along with Durability And Reliability along with it being Aircraft Carry-On Compliant Is A Super Plus. So Much Power In A small powerbank.

PROs and CONs; Trickle Charge Mode
Purchased the Anker 20,000 mAh Power Bank to replace my old Power Bank for 2 reasons: 1) Has a built in USB-C charging cable and 2) Wanted a super fast Charging Bank. In general, very satisfied with the product but one disappointment (see below):PROS:1) Integrated USB-C charging cable very convenient. Cable that fits so snugly in its indented slot that it is completely flush with the remainder of the power bank. There is no chance that the cable will unravel or snag on objects that might result in damage to the cable2) The USB-C ports and the USB – C integrated cable are indeed super fast chargers. Subjectively they charge 2X faster than my other standard charging bricks.3) Love the ability to check the exact charge level of the bank( measured in % of full charge) by a simple push of a button at the top of the bank.4) Using a USB-C port, to charge up the bank to 100% capacity is surprising quick.5) Anker quality and reliability.6) Plenty of battery storage to recharge devices many times over.7) Trickle Charge Mode- I didn’t even know what this was until I saw a video review of this battery bank. Apparently some battery banks cannot charge “low -powered” devices like earphones (battery bank will keep shutting off). This bank will also shut off UNLESS you activate “the trickle charge” mode by pressing the top button TWICE. Once you press the button twice a green light will appear on your battery status screen to acknowledge the above. Not all battery banks have a trickle charge mode. This one does.8) Retains Charge- I will charge battery to 100%. It sits in my drawer for greater than a *month and it still has the same 100% charge. *Addendum: Used the battery for several months now. Maintains charge of “100% ” after 3 months of non-use.CONS:1) USB- A Port- Not a really fast charging port but not slow either. To me, seems like just a normal charge speed. No better or worse than a normal brick. This was a big disappointment in that this is advertised as a “max fast charge battery pack”.2) Short integrated USB-C cable- only 6 1/2 ” long. Very Short leash for charging your devices. Check length to see if this will work for your uses.SUMMARY : This is a great product from a reliable manufacturer that has attractive features ( integrated Cable, quantified charge level and has quick USB-C charge ports) but has normal quickness for the USB-A charge port. Again, this is my admittedly subjective opinion but hence, a 4 star rating. However, If all the devices you need to charge are USB C compatible, then this would be a 5 star product for you.Update: Used product for almost 8 months. It’s been abused (dropped multiple times in my backpack) and still works like new. Impressed by retaining battery level after many months without use but just wish it was a little lighter.

Works as advertised. No complaints.
I wanted a power bank that could fast-charge my phone. This power bank works as advertised so far. I also used it on a laptop. While it charges my laptop without issue, I recommend not doing this. The laptop drained fast. The included built-in USB-C connector cable is very convenient and tucks away right on the casing. Now I don’t have to remember carrying one for my phone on the go. Very thoughtful feature. So far so good, I recommend.

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.
