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.

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!

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.

Powerful and fast charging!!!

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.

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.

Power bank Holds charger longer than expected. Solid build
