AnkerPower Bank, 321 Magnetic Battery (PowerCore Magnetic 5K), 5,000mAh Magnetic Wireless Portable Charger, Compatible with iPhone 16/16 Plus/16 Pro/16 Pro Max, iPhone 15/14/13/12 SeriesClimatePartner certified

I bought this to augment an old 12mini with a 75% battery. They magnetise together well through apple case and its like leaving it on a wired charging panel. If you leave it attached beyond 100 I found it bleeds away the rest of the store so it's not quite like a case with a battery. It's not too heavy and it feels very sensible and practical. It does somewhat defeat the object of the 12mini size ....but used sparingly it tripled battery life.We also tried with a 13 pro max. It didn't add much weight relatively to this much bigger phone and it came in very handy over the course of a long day event with lots of photos etc. It probably doubled the life.It also works particularly well on my older samsung S10, so much so I have ordered a magsafe case to attach it more securely.If you use it with a cable it seems to work like a very efficient power bank.Takes ages to charge which is a bit of a chore.4.5 stars for performance, 5 for quality and price.

This Anker power bank is excellent for a battery backup when on holiday. It’s small, lightweight and clamps itself firmly to my phone. Its not particularly quick but these MagSafe batteries aren’t. When my iPhone started to run out towards the end of the day I could attach the power bank and continue to use the phone while it charged. It didn’t fall off and it charged an iPhone 14 once. It will charge more quickly if you attach the phone to the battery via a cable but that defeats the object if it.

Love this - it’s fast and easy to use; but it needs recharging often. That’s fine for me. But that’s why I took a star off.

I got this on a recent prime day. I wanted to go MagSafe for a power bank. Good magnet. Looks good with my starlight iPhone 13. I wish the capacity was bigger but it’s a great capacity for those top ups and it can be used for anything that is USB. It’s quick changing and provides at least 1 full iPhone charge. It does get warm like all power banks. I am a fan for Anker products and this is no different.

I basically had the same experience as this buyer who wrote: “ Takes ages to charge then runs out even when not in use. Charged it fully to take away, didn't use it at all but two days later it was completely flat. Useless and I can see no way to return it.”I charged before flying on a short trip in europe. When I arrived and tried to use it some hours later the battery was completely flat and now it won’t charge again when I plug it in. Really disappointed as I now don’t have a charger to take out with me.

This is my first MagSafe battery that I have tried. Since Apple have discontinued their version of the battery, I thought the most obvious solution was to go to Anker. Positives about the batteries that it's a good quality build and is very convenient WHEN it is fully charged; you just pull it out of your bag, snap it on, then done. I found before that even when I carry a back up battery that I don't end up charging my phone because it's too inconvenient to run a cable from my back to my phone, so this solves that issue.The main problem is that the charging time is so excruciatingly slow it seems to me to defeat the purpose which someone like me would seek out this device in the first place. That is, if you are the type of chap who isn’t diligent about keeping everything charged at all times, having a slow charging time might as well mean you will almost never in the perfect situation where you’ll have remembered to charge your battery before you need it. This battery bank charges at ~8W. To someone who needs a quick top up within 30 minutes, this is a lot slower than other batteries which can do up to 20w, so you end up getting way less juice in a small window of time.Keep in mind there is also the issue with the inefficiency of wireless charging. This won't be a problem exclusive to this battery. So not only will your phone battery run very hot while charging, but it will also charge your phone very slowly. When I've had this battery on full, I've always tended to use this as a temporary backup battery to keep me going for a few more minutes rather than expecting it to top up my phone at all.

The best portable charger I've used due to its lack of cables and accessories - you just stick it on and go! Of course, while the size makes it really easy to carry around and to keep your phone in use with it attached, it does also mean that it only holds about 1 full charge, but that tradeoff has been totally fine for me. I bought this particularly for a city break, andfound it was ideal for carrying round in my pocket all day then giving my phone a boost after lots of google maps / camera usage, then I just charged it back up overnight ready for the next day.One thing to note is that it can get very hot while in use, particularly if kept in your pocket! This has been fine so far, but wherever possible I try to keep it out on a table or in my hand to mitigate this slightly.All round great product though - decent charge speed for what it is, lightweight and slim for portability, battery indicator which is handy, good magnetic connection, and pleased it comes in interesting colours other than just black!
