Works well, but drains pretty much for a full mobile charge
When you plug it in to charge the Power Bank, it just sits there for a while doing nothing. The power level remains unchanged and you wonder if something is wrong, you got a defective piece or what, is the charging cable the appropriate one, etc. etc. But, then after some time, (havent timed it yet) it suddenly starts charging and then it charges pretty fast. The product is sleek and all and works well, but it pretty much uses up all its charge to charge my mobile fully from say 10%. I thought I would get at least two charge cycles but, this was a little disappointing. But, otherwise the device looks great and works fine.

Stopped Working Within a Few Weeks – Will Update After Warranty Claim
I purchased the Anker 87W 20,000mAh Power Bank (Model A1383) from Amazon with high expectations, given Anker's reputation. The power bank initially worked great – fast charging for my phone, tablet, and even my laptop. The built-in Type-C cable is also a nice convenience. However, just within a few weeks of light usage, the power bank suddenly stopped working. It no longer charges, powers on, or shows any response. This is really disappointing, especially for a premium-priced product. I’ve now initiated the warranty claim process. Depending on how smooth or difficult the process is, I will update this review later to reflect my full experience. Pros: Excellent charging speed while it worked Solid build quality Built-in Type-C cable is useful Cons: Completely stopped working within weeks Reliability is a serious concern Now waiting to see how the warranty process goes Anker usually makes reliable products, so I'm hoping this was just an unfortunate one-off issue. Will revise the review based on their customer support and replacement process.

Honest Review
Great charging capabilities.... Supports fast charging in most of the devices. Colour is neutral black. U can charge any device... without any hesitation (ofc it has to be type C supported)... Compact...but heavy obviously it's a 20000mAH... If someone asks why should I buy Anker when I can get other brands for less prices...yes u can get....but Anker is a premium international brand...and the features it's providing...for me it's Value for money.

Huge and heavy but has a big heart! 🤎
I carry it with me all the time, just perfect for my needs but it is a little bit on the heavy side so don't try to use your phone while charging it using this power bank and that is to be expected of such a device. The build quality is excellent and it is also fairly priced compared to other options in the market.

Sehr leistungsstarke Powerbank mit praktischen Features
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.

Parfait !
Je recommande à 100% ! Affichage numérique très pratique et fiable. Ne se décharge pas si elle n'est pas utilisée. Se recharge rapidement. Réalise jusqu'à 4 charges complètes d'un téléphone. Peut recharger 3 appareils en même temps. Super pratique pour moi qui suis souvent en extérieur et qui utilise beaucoup son téléphone.

Worth the buy
This powerbank is amazing. Charges my devices so fast and also recharges amazingly fast when charged with an authentic 65watt GAN charger (i used anker 65w GAN charger). I've never seen a powerbank charge that fast before like this one. It's perfect in size and shape, not heavy and not light. It's worth the price and worth having as a backup power pack. Highly recommended
