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 × 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.
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.

Perfect for Travel, Work, and Everyday Use!
I don’t usually write reviews, but I had to for this Anker 20,000mAh Power Bank with Built-In USB-C Cable because it has made my life so much easier. I’m always on the go, whether it’s for work, traveling, or just running around all day, and my phone battery never seems to last as long as I need it to. This power bank has been a lifesaver more times than I can count.The best part? The built-in USB-C cable. I can’t tell you how many times I’ve forgotten to pack a charging cable and ended up scrambling to borrow one or buy a new one. Now, I don’t even have to think about it. The cable is sturdy and well-attached, so I never worry about it breaking. I use it mainly with my Samsung Galaxy S23 Ultra, and it charges super fast—faster than I expected for a power bank!The 20,000mAh capacity is no joke. I’ve been able to get almost four full charges out of it before I have to recharge the power bank itself. This has been a lifesaver on long flights, road trips, and even just busy days when I don’t have time to stop and plug in. It’s a little bigger than some other chargers I’ve used, but honestly, the power it holds is worth it. It still fits easily in my bag, and I’d rather have the extra battery life than a smaller power bank that dies quickly.I’ve been using this for a few months now, and it’s super reliable. The battery indicator lights are helpful, so I always know how much power I have left. Plus, the build quality feels really solid, like it will last me a long time.If you need a dependable, powerful, and convenient charger, I 100% recommend this one. I take it everywhere now and don’t know how I lived without it!

Works great, super portable, long lasting
I was having issues with my previous 10,000 charger with a bad port and I upgraded to this bad boy. I’ve gone on multiple week long trips since buying this and so far*fits in my fanny pack / crossbody bag* has an extra port so i can plug in my friends phones* I can do day trips and charge once or twice a day being out and about, not at all worried about running out of juice (the % helps so I just top off my phone whenever I’m low)*When I’m working remotely, I also don’t bring my charger around- this thing surprisingly can handle me working for an hour.* the bank itself chargers a lot faster compared to my previous models, probably due to USB-C. It makes downtime a breeze since I don’t worry about charging my phone as often.The only iffy complaint I have about it: the built in USB C cable s integrated and feels less durable than other anker/OEM chargers I have so I’m worried about how to replace it if it ever frays.It also doesn’t charge multiple devices at a time well, so although you can- keep one devie plugged at a time.It is a little chunky/heavy so I wouldn’t recommend it in a smaller/cute purse.Other reviewers have noted the Trickle Charge mode, but it is an annoying feature to troubleshoot – it struggles to charge my airpods or watch. Unless you activate trickle charge, it won’t charge low powered devices.

Big. If you are used to a 10K, this is big. But it is great.
I’m used to a 10K Anker with a built-in cable but they don’t make it anymore. Since I now have a laptop that can charge with USB-C I got this high-output power bank. This works great for the computer, it works great for my son on a flight (heavy heavy phone user). The weight and bulk I don’t like, but for now that’s the nature of the beast. The built-in cable is great, and it has 2 other ports (a C and an A) which make this flexible. Having high power output is great (it does a good job charging my OnePlus 9 Pro) and although I got a “like new” that was “obviously used”, I’m still happy about it. The display showing the charge level is nice. I wish it would tell me how much power was going out, but if this gets lost, I’ll buy a replacement. And it is Anker which has been a favorite of ours for years and years.

Compact, Lightweight and Super Functional
This Anker Power Bank is a lifesaver! Its compact size and lightweight design make it easy to carry around, and the built-in USB-C cable is incredibly convenient. No need to pack extra cables!I mainly use it to power my router during power outages, and it works perfectly. With 20,000mAh capacity and fast charging, it’s versatile enough for all my devices. Highly reliable and worth every penny!

Un peu lourd mais vu la capacité, c’est normal.

I’ve used several Anker powerbanks for over 7 years, and it has always delivered. Buy one and you won’t need another for many years (7 at least in my experience). I gifted my older power bank and bought this one. The performance is unbeatable, and the support is even better. I had to contact customer support for the first time, and they guided me on how to reset the device. I can charge my phone 4 to almost 5 times from 20% to 95% (battery hygiene reasons) easily. This one is a bit heavier and can’t be held in your pocket, comes with a decent sized wire that supports fast charging, and a small display to track battery health. The support staff was willing to send over a new device in case I was not happy with the performance, and eventually gifted me a 27,650 mah power bank which is a beast. Just like Amazon, Anker truly cares about their customer happiness. Don’t look any further, and just buy it.

Besitze seit dem 29. Juni 2024 | 5 von 5 SternenPro: • Leistungsstark • Hochwertig verarbeitet • Gut durchdachtes Design mit integriertem KabelKontra: • Etwas schwer • Nicht ideal für leichte AusflügeIch bin absolut begeistert von dieser Anker Powerbank mit 20.000mAh und kann sie nur jedem empfehlen, der auf der Suche nach einem leistungsstarken und durchdachten Ladegerät ist. Nach mehreren Powerbanks, die ich in der Vergangenheit genutzt habe, ist diese mit Abstand die beste, die ich je besessen habe.Erst einmal ist die Ladegeschwindigkeit beeindruckend. Mein iPhone 15 Pro wird mit dieser Powerbank genauso schnell aufgeladen, wie wenn ich mein 61-Watt-Apple-Netzteil verwende, das eigentlich für mein iPad gedacht ist. Das spricht Bände über die Qualität und die Power dieser Anker Powerbank. Mit bis zu 87W maximaler Leistung ist sie in der Lage, sogar mein MacBook effizient aufzuladen, was für ein tragbares Ladegerät wirklich bemerkenswert ist.Ein weiteres Highlight ist das integrierte USB-C-Kabel. Das ist eine durchdachte Lösung, die einem die lästige Suche nach einem Kabel erspart. Einfach das Kabel ausziehen und los geht’s! Man sollte nur beachten, dass es sich um ein USB-C-Kabel handelt – perfekt für moderne Geräte wie das iPhone 15, MacBook oder Samsung Galaxy, aber auch für die Nintendo Switch. Natürlich gibt es auch die Möglichkeit, ein eigenes Kabel anzuschließen, da die Powerbank über zwei USB-C-Anschlüsse und einen USB-A-Anschluss verfügt, was sie unglaublich vielseitig macht.Ich nutze diese Powerbank jetzt seit fast 1,5 Monaten und das fast täglich! Sie hat mich in dieser Zeit nie im Stich gelassen und funktioniert immer noch wie am ersten Tag. Das zeigt, dass Anker hier nicht nur ein leistungsstarkes, sondern auch ein sehr zuverlässiges Produkt entwickelt hat.Die Qualität des Produkts ist, wie bei allen Anker-Geräten, hervorragend. Die Powerbank fühlt sich robust und hochwertig an, und die Verarbeitung ist einwandfrei. Auch die Lieferung und Verpackung durch Amazon waren, wie immer, schnell und ordentlich.Diese Powerbank von Anker hat mich auf ganzer Linie überzeugt und wird sicherlich mein treuer Begleiter auf Reisen und im Alltag sein. Anker hat es wieder einmal geschafft, ein Produkt zu liefern, das in Sachen Leistung, Design und Funktionalität einfach überzeugt. Absolute Kaufempfehlung!Euer REDTAC 🫶
