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.

Reliable Power Bank for Heavy-Duty Travel Needs
I purchased the Anker Power Bank 20,000mAh as a travel backup, and it’s been a dependable option for larger charging needs. It is on the heavier side, but still compact enough to take on an airplane without any issues. It also holds a charge extremely well when not in use, so it’s always ready to go. Having the cord attached is a big plus—one less thing to pack or lose. A solid choice for travel, long days out, or anyone who wants reliable extra power on hand.

Bulky, Hefty, but Perfect in All Other Regards
This thing has been my buddy for when I travel. I regret if I don’t bring it. If it’s just for my phone, it will last me multiple days until it needs to be recharged.I’ve been able to help myself and my friends out whenever we have a low battery, and with how fast it charges, you rarely have to wait long. Even in bed, I won’t have to hold onto it for long before it gets me at a stable battery level to doomscroll into the night.Only cons are the weight and size, but it’s reliable and does its job perfectly otherwise. Just small enough to fit into a pocket, but it’s bulky and heavy. Maybe doable behind an inner hoodie pocket, but most easily accessible and hidden from a backpack or handheld bag.

Very capable portable charger, with the usual Anker quality
During recent travel, I ran into a problem after some airport delays: While my tablet was fine, my phone’s charge (from which I was streaming music) began dropping alarmingly low and I didn’t have a ready means to recharge. Well, I decided to address that problem during a recent Prime sale.For me, the prime factors included having a lot of available power, and 20k mAh is near the top of what’s allowed in the US by the TSA, but well within the limits (it’s 72 Wh) for a powerbank, and as is usually helpful if not required, this number is printed (albeit in very small type) on the backside of this Anker powerbank. Side note: As I write this review, powerbanks are limited to 100 Wh max and must be carried in one’s carry-on or personal item (such as shoulder bag); these are not to be in checked bags.Capable of delivering 87W total to multiple devices, this powerbank has the usual Anker quality: Sturdy case, clean design, and about as slim and compact as a 20k mAh powerbank can aspire to be. That is to say though, it’s a little bit on the heavy side, so this is something you’ll want to carry in a bag and not, say, try to tuck into your back pocket. (Although technically, it’s small enough for that…it just won’t be comfortable and could fall out, I suppose.)The controls are simple: One button to turn it on, at which point you can see the percentage of power remaining. The LED display is clear and bright, and I can even read it without my progressive glasses. As with most Anker products of this type, it has iQ ports, one with USB-C and the other USB-A. It also comes with an included attached short USB-C cable that neatly tucks into a channel around the bottom and side of the unit. It’s worth noting that only the two USB-C ports can be used for charging the power bank. The USB-A one is output-only. Just something to keep in mind.In terms of durability, I guess I’ll find that out over time, but I’m pretty confident it’ll hold up. I have some very old Anker powerbanks that I keep in my Power Outage 5-gal bucket and despite leaving them in there charged up, they still work fine.I would buy this again, although it was nice being able to get it on a Prime day sale price. I do now just keep it in my shoulder bag and have that peace of mind that I needn’t worry about either my phone or tablet running out of juice when I need them the most. For travel, I figure the only other thing I’d do is add another short USB-C cable to my bag and be good to go.

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!!

Fast and high capacity.
Great charger/power bank. Used for several brands of phones, portable games, flashlights, etc. Super fast charging my Samsung Galaxy s23 and s24 ultra without issue. Huge capacity. I like having the cord attached. Nothing to have to remember when going out. Just grab n go. It’s a tad heavy and bigger than some other 20,000mah power banks so only 4 stars from me. Highly recommend if you don’t care about size.

Love all the features
Great power bank. 20,000mAh provides plenty of power for my devices. Primarily use it to charge phones and occasionally my MacBook Pro. LCD indicating battery level is a nice tough. Fast charge and it recharges pretty quick.The size is perfect as it fits into one of my backpack pouches.Would definitely buy again.

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.

Ich habe mir die Anker Powerbank mit 20.000mAh gekauft, um unterwegs zuverlässigen Strom für Smartphone und Laptop zu haben, und bin sehr zufrieden. Schon beim Auspacken macht sie einen hochwertigen Eindruck: das Gehäuse ist stabil, kompakt und wirkt langlebig.Die Kapazität reicht locker aus, um mein iPhone mehrfach vollständig zu laden. Auch mein MacBook oder die Switch lassen sich damit problemlos versorgen. Besonders praktisch ist die hohe Ladeleistung von bis zu 87W – dadurch werden Geräte spürbar schneller geladen, was im Alltag wirklich Zeit spart.Sehr gelungen finde ich auch das integrierte USB-C Kabel. Man muss nicht ständig daran denken, ein Kabel extra einzupacken, sondern hat es immer direkt dabei. Zusätzlich gibt es noch einen USB-A und einen weiteren USB-C Anschluss, sodass man mehrere Geräte gleichzeitig laden kann. Alle Ports liefern zuverlässig Leistung, und die Powerbank wird dabei nicht übermäßig warm.Das Gewicht ist für die Größe und Kapazität in Ordnung – natürlich kein Leichtgewicht, aber absolut tragbar für Reisen, Arbeit oder längere Tage unterwegs. Die Verarbeitung ist wie gewohnt bei Anker top.Die Lieferung über Amazon war schnell und gut verpackt. Insgesamt eine sehr durchdachte und leistungsstarke Powerbank, die zuverlässig funktioniert und jede Menge Reserven bietet. Für mich aktuell eine der besten Lösungen, wenn man viel Leistung in einem kompakten Gerät sucht. Klare Kaufempfehlung.
