Anker Power Bank, 325 Portable Charger (PowerCore 20K II), 20,000mAh Battery Pack with 2-Port, 15W High-Speed Charging for iPhone 16/16 Plus/16 Pro/16 Pro Max/15/14/13 Series, Samsung Galaxy and More

Amazing charger well worth the investment. I cannot comment on the longevity of this product as I’ve only had it for 3 months- so far so good! I went to Glastonbury and it only lost 1 bar for the full 5 days charging my phone! Also just got back from a 4 day trip and it lasted the whole time charging 2 phones and an Apple Watch multiple times a day. Pros: -long lasting charge - 2 USB ports and 1 USB C port - I can charge my iPhone 15 it’s hard to find portable chargers with USB C Cons: -takes a while to recharge - on the heavier side but not awful

Super impressed with this battery pack. I bought it to replace my previous large capacity battery (not Anker) which had fallen out of the top of my rucksack onto a train platform and started to swell up so I had to recycle it (context for what's to come) Having had good experience with previous Anker products I went for this one and have so far been really impressed. It's first job was to keep 3 GoPro batteries charged during the day on a 14 day motorcycle trip where we were recording constantly. It delivers a quick charge and was easily able to keep the batteries topped up. On the first night I accidentally knocked it off the 2nd storey balcony of my hotel room and it fell onto the concrete path below. I was expecting this to be terminal for the battery pack, but I was pleasantly surprised to find the plastic case just had some scuff marks on it but was not cracked, and the battery powered on as normal. I was a bit concerned about the battery internals might have been damaged so I cautiously plugged it in to charge and there was no excessive heat, the battery had not swollen up and other than the scratched case, it was performing as expected. The capacity of the battery is ideal for times when you don't have access to electricity (it kept my phone and watch charged on a 4 day camping trip), and the low power mode is great for trickle charging items with a small battery like watches or earphones. If I had one criticism it would be the time taken to recharge the battery. Despite having a USB-C port it does not seem to charge any quicker than my old micro-USB battery pack. But provided you're happy to leave it charging all day/ overnight, I would thoroughly recommend this battery.

Powerful and fast charging!!!

The Anker Power Bank, 325 Portable Charger (PowerCore 20K II) is a cracking bit of kit for anyone needing reliable on-the-go power. With its hefty 20,000mAh capacity, it can easily charge your phone multiple times before needing a top-up itself. This is especially handy for long trips or when you're out and about without access to a plug socket. One of the standout features is its dual USB ports, allowing you to charge two devices simultaneously. This is a real lifesaver when both your phone and tablet are running low on juice. The charger is also quite compact for its capacity, fitting nicely into a backpack or even a large pocket. However, it’s not without its flaws. The power bank is a bit on the heavy side, which might be a downside if you’re trying to travel light. Additionally, it takes quite a while to recharge fully due to its large capacity. Overall, the Anker Power Bank, 325 Portable Charger (PowerCore 20K II) is a reliable and powerful option for keeping your devices charged on the go, despite its weight and lengthy recharge time.

I bought this for use at a festival and can honestly say it’s very impressive in terms of charging for long period of time. I have two phones and it lasted the entire 5 days! I would say it is an absolute beast to charge the actual charger itself though, it usually takes a day or two to fully charge. And it is heavy. Really heavy. So I have a smaller charger for day to day use just as it makes my bag painful to carry and it is quite large. But for its intended purpose (charging) it is absolutely great!

This has been used a few times now and works well. It's a good size, charges quite quickly and holds its charge well. All in all a good buy.

Power bank Holds charger longer than expected. Solid build

I've been using this powerbank for about a year and a month now and it's definitely worth the price. It charges my phone at least 3 times to 100% plus my other devices. I definitely recommend. Although its on the heavier side but its not really a negative for me. Battery life is amazing but it needs to charge overnight for it to be 100% again.

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.
