AnkerPower 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

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.

Works really well but fairly heavy to carry in handbag

I've owned the predecessor of this device which 7 years ago I bought and it's still going strong as a battery pack to give me an exte charge or two. Girlfriend wanted one for her iPhone and to charge her boss earphones.Reasonably compact, more suited for small bag than pocket sized but could fit in a larger jacket easy.Simple to use. Two ways to charge. Usual or trickle depending on the power your devices need.Easy to gauge capacity at any time with quick indicator.Girlfriend says "it isn't too heavy" which frankly is great for her little adventures with her Dora the Explorer backpack.She also said "Well made and doesn't feel like scratch plastic"Girlfriend approved and I have no doubt this is a solid smaller battery pack easily for day to day use or a emergency back up..Only drawback is you will need a USB C cable to charge it. Which isn't really a drawback in this current time

Bought for my son to take on a school skiing trip last year. It takes a long time to charge, but once fully charged it lasts a long time. It lasted the whole journey there (by coach, so about 26 hours) and the trip back (also by coach), plus the occasional charge during the week. My daughter now uses it for nights out, as she's always on her phone so runs out of battery very quickly. It's also very handy to keep charged in case of any power cuts in the home.

It did come with a few scratches on it however the power bank itself is perfectly functional. It can charge your phone perfectly came with a cable connected. Has a great battery life. Good capacity. And cannot charge your phone while itself it charging but didn't find that necessary anyway.

Bulky but excellent for what I wanted it for.

It takes a while as expected to charge up, but then will give me peace of mind to have at hand especially when travelling abroad. Heavy and solid construction.
