Anker Portable Charger, 20,000mAh Power Bank, Battery Pack with 1 USB-A and 1 USB-C Ports, 15W Max Charging for iPhone 16/15/14/13/12 Series, Samsung Galaxy, and More (Black)

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.

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.

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.

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.

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.

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!

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 love Anker products, they've been on top of their game for a long while now. This is a great power bank. It is slow to charge, but this is obviously due to it's high capacity, so just be aware of that. Only complaint is that the capacity is not 20,000 mah as stated. I'm getting just about 17,000 mah on my meter, several attempt to drain the battery completely and recharge have all yielded the same result. You'll lose roughly 20% during transfer of energy, so this leaves you with about 13,600 mah. Just another thing to be aware of, doesn't take away from how good it is.

Potrzebowałem pojemnego akumulatora aby zasilać mały streamer. Wybrałem białą wersję aby odejść od wszechobecnej czerni urządzeń elektro. Dwa porty (USB A i C), dyskretny wskaźnik naładowania, estetyczna obudowa i duża pojemność. Spodobał mi się tak bardzo, że natychmiast zamówiłem drugie urządzenie. Po kilku tygodniach użytkowania jestem mega zadowolony.

J'en avais déjà une (l'ancienne version) qui a très bien fait son job pendant presque 10 ans !!! Cette version est top (attention, elle reste lourde à transporter et ne rentre pas dans les poches d'un pantalon) mais elle semble inépuisable !!

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:)

My old 20k powerbank from Anker which I have had for about 5 years got swollen. I think I had dropped in in the ground or something so a cell got injuried. But I'm really happy with Anker products in general so I ordered a new one. This one seems a little bit bigger in size.

After experiencing disappointment with lesser-known power banks in the past, I decided to give Anker a try. The results left me truly impressed. Here's what I found during my testing: Real-World Performance: Using an FNB58 USB tester and a constant current load set to 2A at 5V nominal voltage, I measured an actual energy output of 68.67 watt-hours. This measurement was taken from 100% charge down to the unit's shutdown via the USB-A port. Why Watt-Hours Matter: Manufacturers often advertise mAh capacity, but the real indicator of a power bank's capability is watt-hours (Wh). It's a standard unit of energy that makes it easy to compare across different devices and doesn't depend on the voltage of the cell. Impressive Efficiency: Anker states the power bank's capacity as 74Wh. My measurements showed an efficiency of over 92%! This means it converts to approximately 18,500mAh (at a nominal cell voltage of 3.7V), which is very close to the advertised 20,000mAh capacity. The power bank even delivers a stable 5V at 3.4A, exceeding the specifications. Highly Recommended: This Anker power bank delivers precisely as advertised and offers an excellent cost-to-performance ratio. It's not only efficient but also aesthetically pleasing. While it lacks PD and quick charging features, it's essential to manage expectations given its price point. Pros: Real-world performance matching specifications Impressive conversion efficiency Consistent and stable output Reliable brand reputation Competitive pricing Cons: Lacks PD and quick charging In conclusion, if you're looking for a power bank that offers both performance and value, Anker should be at the top of your list. This power bank has certainly won my trust and approval. You can count on it to keep your devices powered, efficiently and reliably.
