Absolutely incorrect, the charging time has nothing to do with the capacity of the power bank, but whether the one you buy supports Apple’s fast charging standard or not. I would recommend you look at Anker because I think especially with Prime Days coming up (provided you have an Amazon prime account) you should be able to get some very good deals. If you want something for at home which you can use of an extended power outage, you should go big as in 20,000 MAH or even better 25 or 26,000 MAH. For example, an iPhone 16 Pro has a battery with a capacity of 3,582 MAH or 13.94 WH (that stands for Watt Hours) and sometimes very large capacity batteries give Watt Hours instead of MAH (Milliamp Hours). Anyways, theoretically, if you have an iPhone with a 3,582 MAH battery and an external battery with 20,000 MAH capacity, you should be able to charge your iPhone completely about 5.5 times (20,000 divided by 3,582). Of course that isn’t completely exact, you may charge your iPhone when it’s down to 8% one day, but maybe when it’s 19% another day. But if you don’t let it run down to 0%, I’d say you will get about 5 charges out of such a battery, get one with 25,000 or 26,000 MAH and you most likely get at least 6 or maybe even 7 charges. The large capacity batteries can usually also charge a laptop which charges via USB-C at 65 or even 100 Watt, and of course you can charge anything which charges via USB like hadsets, Bluetooth speakers, Bluetooth keyboards, an Apple Watch, an iPad etc. Nowadays these batteries typically have at least 2 and sometimes they have 3 or 4 ports, some are USB-C only whereas many still have at least 1 USB-A port (the older, larger port). Keep in mind that fast charging an iPhone typically will be via USB-C as you need at least 25 Watts output and 30 Watts is better. I have a large battery from Hyperjuice which can output up to 240 Watts and it has 1 port which can output 140 Watts which is required if you want to fast charge a Mac laptop. While I don’t have one of them, I have used it for my laptop, of course my iPhone and other stuff. It has 4 USB-C ports, as I said, 1 can deliver 140 Watts, 1 can do 100 Wats and the 2 remaining can do 60 or 65 Watts and they also work in reverse for charging the power bank. Keep in mind that your total output is always divided up across all the ports, e.g. if I were to use the full 140 Watts to fast charge a Mac laptop, then I wouldn’t have the full 100 Watts and 2 times 65 Watts available on the other 3 because that would exceed the total capacity. The good thing is that you don’t have to really worry about it as it regulates itself and just as with wall adapters which deliver 100 //Watts or 140 Watts per port, you can safely plug in a headset which only requires 5 Watts because the port will only deliver what the device can use. Similarly, if you have an older battery which can only deliver say 10 Watts, you can plug an iPad into that port and it will charge, but very slowly. Anker even makes power stations, those are not really portable or at least not to the point where you can easily put them in a backpack because they are maybe the size of a car battery, but they are meant for somebody who, for example, maybe has a cabin out in the woods somewhere with no power, but they want to make sure they have enough juice for the weekend to charge their laptop, iPhone etc. Anker makes an entire line of such devices under the name “<https://www.ankersolix.com/ca/collections/portable-power-stations> Anker SOLIX <https://www.ankersolix.com/ca/collections/portable-power-stations> “ and you can get systems which pretty much can run your home and which cost many thousands of dollars.
Another thing to keep in mind is that if you plan to bring your power bank along when you travel, you must put it n your carry on luggage if you fly and to be taken on an airplane, it cannot exceed a capacity of 100 WH which is MAH is 27,000. This is why most external large capacity batteries are 25,000 or 26,000 MAH as this comes in at just under the 100 WH limit..

Hi list! I am considering purchasing a portable charging power bank for my iphone. I thought that it might be a good idea to have something like this for times when a storm or something knocks out the power. Can anyone tell me the difference between the chargers that say 10,000 Milliamp hours and the ones that say 20,000 Milliamp hours? Does it concern charging time or number of charges? -- The following information is important for all members of the V iPhone list.
