    It's quite heavy and bulky, bigger than my phone, so wouldn't be suitable to put in jean pocket when out and about.
    I've used it to recharge my phone three times, and there was still 50% charge left in it.
    It does take hours to charge from zero to 100%. The light indicators only gives the level of charge in 1/4 increments, 1 light on = 25% charge, 2 lights = 50%, and so on.

    It's perfect for long travels.

    Works well and needs fewer recharges than similar looking cheaper ones. Doesn't have built in cables but pair it up with a fast charge cable and it's worth the extra cash.

    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.

    Very good power bank!
    I was on a 5-day expedition, and the power bank charged my phone and smartwatch 5 times each before it died on the way home!
    It’s quite heavy, scratches up easy and takes a while to charge up. But for saying it charges my phone at least 5 times it’s great quality and value for money!!!

    Absolutely great value for money for the amount of battery capacity you get, this is actually a really good size and doesn't weigh that much for how much battery it has. For scale it's the exact same size as my phone (pixel 7 pro), and about two times the thickness (obviously).

    If you don't want this size then you're just going to have to compromise and get less battery life, you can't have it both ways. But this is the best for the amount of juice you get with a more than reasonable size and weight, especially with it's fast charging! I easily get 4 full charges on my Google pixel 7 pro, and it also easily charges my Nintendo switch, I haven't tested how many chareges I get out of it for that yet but I'm sure it could handle a couple.

    This is also amazing for travel because it's comfortably under the top limit for flying at 20,000 mah when the limit is 27,000 mah, so I don't have to worry about airport security taking it.

    5.0 out of 5 stars Solid powerbank with essentially no downsides
    Reviewed in Canada on 31 December 2024

    I have zero complaints.

    Not sure what to say here - this is a great battery bank. It charges via USB-C (great), can discharge via either USB-C or USB-A (great), has a ton of capacity (great), has a trickle-charging mode (great)... There really aren't any downsides to it other than its weight, as it is heavier than some comparable powerbanks of the same capacity.

    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.

    5.0 out of 5 stars Schwerer Brecher aber sehr leistungsstark!
    Reviewed in Germany on 5 January 2025
    Colour Name: BlackVerified Purchase
    Handlich ist das Teil nicht - schwer und klobig - aber die Leistung überzeugt auf voller Linie. Und Robust ist es auch.
    Blitzschnelles Laden insbesondere über USB-C, für mein Iphone 13 sind mehr als 4 komplette Akkuladungen drin, das Wiederaufladen dauert nicht zu lang. Perfekt wenn man auf Reisen ist. Ich benutze es aber auch zu Hause, wenn ich mein Handy laden aber flexibel benutzen möchte, zum Beispiel draußen. Ich finde es gut, dass sowohl normaler USB als auch USB-C Anschluss dran sind - sowohl zum Aufladen als auch zum Laden. Ich empfehle allerdings sehr USB-C zu benutzen - es ist so viel schneller!
    Qualität hat seinen Preis - in diesem Fall ist es das Geld Wert. Einziges Manko ist das Gewicht.
