Anker 521 Magnetic Battery , 5000 mAh Wireless Portable Charger with USB-C Cable, for iPhone 13 /12 series (Black)

I have used Anker products for a few years now and I have always been impressed with them. This unit is no different I occasionally drive a company truck for work which doesn’t have usb-c charging and that is one of the main reasons why I chose to get this charger. This charger is small and compact which is great because it can fit in any pocket and I love the fact that if I don’t have a charging wire I can just slap it on the back of my phone which is so convenient! (However make sure you have a MagSafe compatible case if you are using an iPhone) The only downside is because of its small battery it will not charge your phone to 100% (via the MagSafe charging feature I have yet to charge my phone via lighting cable) if your phones battery is lower than 25% but it will give you enough charge to get through your day! All in all I’m very pleased with this charger!

It doesn’t have a lot of power but i find it just right to get me by my day. The magnet is nice and strong so it’ll stay on your phone no matter what. I have an iphone 13 pro and it charges my phone to about 80% when its at 10% only downside is that it charges very slow but i dont mind it since its just stuck on the back of my phone and i don’t really notice it. Its just perfect to get you through the day without having your phone die.

This battery is priced much more fairly and has a higher capacity than Apple's own MagSafe Battery. Of course, you won't get the software integration of Apple's battery with Anker, but is the software features worth an extra $50-60, while losing out on battery capacity? That's up to you.Anker's battery has a more than strong enough magnet that keeps itself locked into place, which would be a huge issue if it didn't. I have an iPhone 13 Mini, and this battery charged my phone from roughly 35%-100% and still had a bit of battery left.The thing about all MagSafe batteries, though, is extremely low charging speeds. Anker's battery suffers from this as well, I believe topping out at 5 watts. This is also an issue with Apple's version as well, though. I think eventually the manufacturers will figure out how to increase both charging speed and capacity in the future, but in the meantime this is one downside for me as you'll have to keep the battery attached to your phone for hours if you're trying to charge from less than 50% to full.Something else I like about the battery is how well it fits with my iPhone 13 Mini. It's aligned perfectly as if it were meant for the Mini. This makes the previous issue of charging speeds less of an issue, because using your phone with the battery attached doesn't feel overly cumbersome, in my opinion.Another nice feature with Anker's MagSafe battery (I believe Apple's version does this as well) is that you can plug the battery into the wall to keep it charged, then place your phone on top of it and use it as a charging pad. I believe you may even get slightly higher charging speeds with this method as well.If you're trying to decide over this battery or Apple's version, here's an overview:Get the Anker version if:- You don't care about software integration- You prefer a larger capacity- You don't want to pay the "Apple tax"Get Apple's version if:- You do appreciate the software integration- You only plan to use the battery to top off your phone's battery in a pinch- You like the all-white design and Apple's simplistic branding

I have so many charging banks that it might be a slight obsession. Standard bricks, wireless, ones with fold out prongs, solar, credit card size, you name it, I have one. This is the first one that scratched all the itches and was something I didn't know I needed until Apple added the mag option. The fact this battery just attaches to the phone and wirelessly charges it so I don't have to hold it separately or balance or use a cable is awesome. It just works and works well. The magnets hold firm when generally holding it with the phone but it will slip if too much pressure is set. The capacity is ideal to get you that extra few hours of use when needed. On it's own, it's not very large which is great. Maybe a little thicker than I would like, but overall I'm still able to hold the phone with the charger attached without problem (I don't have the Pro). It definitely adds weight to the phone when attached, but not as much as you might think. This is going to be my portable charger going forward.

Oh though it didn’t have the strongest magnets or the best battery life but in some cases that’s how it’s gonna be. Mag safe loses a lot more battery when wirelessly charging than a cable and also makes it slower. But I found that if your case is grippy on the back it won’t slid as much and the magnets won’t matter at all! The only thing you can’t fix is the charging speed but it’s nice that’s it’s slow in one way to help out with the life of your phones battery and overheating. After the end of the day I can charge my 12 pro to 75 percent in the whole packs charge. And on other nice thing is I can use it normally with a usb c cable to lightning for the full use of that 5k battery.

This battery pack has been awesome, loved it for quite some time,. However out of the blue it ceased charging, charging devices or shutting off. It not continuously blinks its 3rd indicator light. After reaching out to Anker support, they denied a replacement request as I was out of the “3 month” warranty period. I guess those are the rules they set forth, but $40 for a battery pack that is only guaranteed to work for 3 months is a bit of a bummer. Definitely was hoping I’d get some good will, at minimum a discount on a replacement since I’ve spent hundreds of dollars on Anker products. Definitely will rethink my next purchases…

Good execution of sale

Just the right size for my iPhone 13 Mini. I wouldn't mind a thinner one (this can probably charge my phone a few times over), but it still fits in the pocket of my Levis just fine while attached to my phone.
