Reliable Power Bank For Travel And Everyday Use
I picked up this Anker 20,000 mAh portable charger to keep my phone and other devices topped up on long days and trips, and it has been very dependable. The capacity is enough to charge my phone multiple times, so I do not have to worry about hunting for outlets at airports, on road trips, or during long days out. Having both a USB A and a USB C port makes it easy to charge two devices at once, like my phone and earbuds, without carrying extra bricks. Charging speed has been solid for a 15 W power bank. It is not a super fast charger, but it is more than good enough for steady top ups and full charges while I am on the move. The build feels sturdy and the finish holds up well riding in a bag with other gear. It is a bit on the heavier side, which is normal for a 20,000 mAh pack, but the trade off in capacity is worth it to me. If you want a reliable, no nonsense power bank from a brand you can trust, this is a very good choice.

Reliable & Fast Charging – A Must-Have!
I’ve been using this Anker Portable Charger for about four years, and it has never let me down! Whether I’m traveling or at home, this power bank charges my devices super fast, even my tablet. The 20,000mAh capacity means I can get multiple charges before needing to recharge it, which is a lifesaver on long trips.Recently, I bought one for my godfather in Cuba, where power outages are common. It works perfectly for keeping his phone and mini fan charged when the electricity goes out. The dual ports are a great feature, allowing him to charge two devices at once. This is hands down one of the best portable chargers I’ve ever owned—durable, reliable, and powerful. If you need a high-quality battery pack, I highly recommend this one!

Good power bank
This is a great little power bank that can charge my phone four times over before needing to be charged again. I also appreciate the USB-C port, which is convenient for charging. This is on the heavier side but it's decent trade-off considering how much charge it holds.

Powerful battery backup as long as you are okay with the bulk
Good power bank, somewhat heavy, but it works well. Can easily last multiple days and very useful when traveling. It is a little bulky, however.

Great but not perfect
I bought this for travel that would take me through several airports. I wanted to avoid charging at the gate and have enough juice to last even on the planes. Charging takes quite some time, but once it's charged, it was more than adequate for the task at hand. It charged both my phone and headphones multiple times without needing to be charged itself. My gripes are minor and didn't affect my trip but they're there nonetheless. It's rather large and heavy. Also there is no wireless option. Again that wasn't critical for me but I'd like to see wireless charging in a future version. When not traveling, it actually works perfect for weekend trips to the beach. I can charge my Kindle or phone while lounging in the sand and waves. For the record I use it with my iPhone 15 pro, Kindle paperwhite, Airpods Pro, and Soundcore Liberty 3 Pro.

bigger than expected, but so is the battery life!
So I have a smaller version of this by Anker (I think 10,000mAh) and don't know why I wasn't expecting it to be bigger. I guess the picture made it look about the same size. It is not, it is thicker, longer, and wider... you know, for the additional 10,000mAh. Knowing that it will never fit in my pocket well, and probably pull of my cargo shorts due to its weight, It's my "I don't have a plug in the middle of my living room" charger. Currently, for a phone, I have the severely outdated Samsung Galaxy Z Fold 3. This device will fully charge my phone four times before I have to recharge it. Huge step up from the two. For other devices like headphones or game controllers, it charge a lot of them up way more times obviously. My 10,000 mAh charger is a good daily driver, it fits in my pocket, can give me a charge on everything I'm carrying, and is stylish and sleek. This 20,000 mAh behemoth is either for traveling, or getting "steady" access to power where outlets are not practical or accessible. No real complaints because Anker is a solid brand that I've been a fan of since 2018 or 2019. They do more than just power solutions, and if you don't know about Anker Soundcore, you're paying too much for a lesser bluetooth speaker/headphone.

Great charger
This charger is great. It holds the charge to itself for a very long time. And I use it for about 3 to 4 days before I have to charge it again and I charge my cell phone with it throughout the day which I have to charge because I’m on it a lot for work and it doesn’t go out fast and it charges my phone quickly and I love that it’s mobile so I can move around with me. The only week it does take a long time to charge, but it’s worth it whenever it is charged.

Great product, great company
I just love Anker power banks. I have been using this brand long before it became popular. I have at least 15 Anker power banks of various sizes and designs. In fact I still have the very first one I purchased at least 17 years ago. Don’t use it for much but still works great and holds a charge. I only buy Anker power banks and cables. I traveled on an airplane 4 times a week for three years, these are life savers…

I’ve been using this power bank for over 1.5 years now, so I feel confident giving a proper review. It has been extremely reliable throughout this time and still performs just as well as when I first bought it. I consistently get around three full phone charges, which makes it perfect for travel, long days out, or situations where you really need dependable power. That said, it is very heavy. It genuinely feels like carrying a brick in your bag. If you prioritise capacity and reliability over weight, this is an excellent power bank. Just be prepared for the extra heft.

Leistungsstarker Begleiter für unterwegs! Die Anker Powerbank 325 (PowerCore 20K II) mit 20.000mAh Kapazität hat sich als unverzichtbarer Begleiter für alle erwiesen, die unterwegs auf eine zuverlässige Stromquelle angewiesen sind. Ich nutze sie nun seit einigen Wochen, und hier ist meine detaillierte Bewertung: Design und Verarbeitung Die Powerbank besticht durch ihr minimalistisches Design und eine robuste Verarbeitung. Sie fühlt sich hochwertig an und ist dennoch kompakt genug, um problemlos in eine Tasche zu passen. Das matte Finish verhindert Fingerabdrücke und sorgt für einen sicheren Griff. Leistung und Kapazität Mit 20.000mAh bietet diese Powerbank beeindruckende Leistung. Sie schafft es, mein Smartphone iPhone bis zu fünfmal vollständig aufzuladen, bevor sie selbst wieder aufgeladen werden muss. Auch größere Geräte wie Tablets lassen sich problemlos mehrmals aufladen. Die Kapazität reicht locker für mehrere Tage ohne Steckdose, was besonders auf Reisen oder bei Outdoor-Aktivitäten praktisch ist. Ladeoptionen Die Powerbank verfügt über einen USB-C-Eingang sowie zwei USB-A-Ausgänge, sodass mehrere Geräte gleichzeitig geladen werden können. Besonders gut gefällt mir, dass die USB-C-Schnittstelle auch als Eingang fungiert und eine schnellere Aufladung der Powerbank ermöglicht. Allerdings wäre es wünschenswert, wenn der USB-C-Port ebenfalls als Ausgang für das Laden von Geräten dienen könnte. Schnelles Laden Dank der PowerIQ- und VoltageBoost-Technologien von Anker lädt die Powerbank alle angeschlossenen Geräte sehr schnell auf. Die Ladezeit ist spürbar kürzer im Vergleich zu Standard-Powerbanks. Besonders praktisch ist der integrierte Trickle-Charge-Modus für kleinere Geräte wie Kopfhörer oder Smartwatches, die sonst oft langsamer oder ineffizient geladen werden. Sicherheit Ein weiteres Highlight ist die MultiProtect Sicherheitsfunktion von Anker, die für zusätzlichen Schutz sorgt. Ich habe volles Vertrauen in das Gerät, da es Schutz vor Überladung, Überhitzung und Kurzschlüssen bietet. Fazit Die Anker Powerbank 325 (PowerCore 20K II) bietet alles, was man von einer hochwertigen Powerbank erwartet: enorme Kapazität, schnelles Laden und einen robusten Aufbau. Sie ist ideal für Vielreisende, Pendler oder alle, die oft fernab von Steckdosen unterwegs sind. Einzig der USB-C-Port könnte als Ausgang für noch mehr Flexibilität sorgen, aber das ist kein entscheidender Nachteil. Vorteile: • Enorme Kapazität von 20.000mAh • Schnellladefunktion mit PowerIQ und VoltageBoost • Robustes und kompaktes Design • Zwei USB-A-Ausgänge für das gleichzeitige Laden mehrerer Geräte • Trickle-Charge-Modus für kleine Geräte • MultiProtect Sicherheitssystem Nachteile: • USB-C-Port dient nur als Eingang, nicht als Ausgang Insgesamt bin ich sehr zufrieden und würde die Powerbank jedem empfehlen, der eine zuverlässige, langlebige Lösung für unterwegs sucht. Deswegen 5 Sterne:)

Mycket bra kapacitet, stark, dock ganska tung, ca 450 gram, och tar relativt lång tid att ladda upp, men en riktig räddare i nöden när man är på resande fot😎
