LISEN 0.3‘’ Ultra Slim MagSafe Portable Charger,5000mAh Wireless Card Slim MagSafe Battery Pack iPhone 17 Air Accessories,Magnetic Power Bank for iPhone 17 Pro Max Plus Air/16/15/14/13/12，Pearl

battery seems to charge fairly fast and get a full charge for an iPhone 16

My household has about 50 or 60 different phone bags, portable batteries, etc. I thought I had found my favorite one. That was a small as possible,… That was until I came across this one by the Lisen brand, which is a phenomenal brand in and of itself.It is only 0.3” wide, so it is definitely, by far the fastest power bank I’ve ever used for my iPhone. The magnet strength is extremely powerful, it’s not very tall, it has a battery monitor display showing four or five bars, which is always helpful, and you use a USB-C charger as the output input.I literally have to hide this power bank for my children because I know they’ll steal it from me and I’ll never say it again. It is the best thing I’ve ever discovered for a travel, power bank, it charges up very fast and the battery lasts an extremely long time. I can charge my iPhone from dead and 0% to full battery life about 3 1/2 times with this Amount of power in this battery.Again, it uses a CUSB cord, it’s extremely portable, you don’t even have to read the instructions, you figure out how to use it so easily in about one nanosecond.There’s nothing bad about this, I would give it 11 stars if I could!

My iPhone 12 Pro Max has a capacity of 3785 mAh or so, it’s also at 81% health. But this battery doesn’t completely charge my phone 100%, it stops at 77%, as the battery seems completely dead at that point, as there are no lights that light up when button is pushed. When full, after pushing the button, all 5 lights light up. Also after removing it and placing it back on the phone, the phone shows no charging symbol, so to assume the portable battery is completely dead is reasonable. While it did charge it did ok, my phone is jailbroken so I can see the charging status live, which also show the amount of charge received. With my phone nearly out of battery at just 12% charge left, this portable battery is charging my phone at a rate of 1429 mAh as shown in the photos below. Since our phones are programmed to charge as fast as possible at this charge level (lower battery levels charge fastest, as the battery has more charge into it, it’s designed to charge slower and slower, 70-80% battery charge would be slowest, to help with battery degrade). With this in mind, we can assume the fastest it will charge is around 1429 mAh, which makes out to be 3-4W, keep in mind it is charging wirelessly as this portable battery is attached via the MagSafe on back, no wires between the phone and battery pack. Going back the charging test, at 39% charge, I checked again and the battery pack continued to charge at the same rate as we began the charging, 1427 mAh (see photos). Unfortunately, this was the last charging rate I could get because I was expecting the battery to fully charge my phone, but to my surprise, it quit charging at 77% (see photos, it instead shows at negative number which means that’s the amount the battery is currently consuming). I’ve charged it multiple times after this, usually start charging at around 10% battery left, I recall it stopped 75%, 73% and 76%. I don’t have any apps or settings that stop the charging at a particular charge level.Unfortunately, I don’t have another wireless charger to test this against, but I believe Apples specs say that my phone charges wirelessly at a rate of 5W, so this charger is pretty close to that. Just the capacity of 5000 mAh is off according my simple calculations of again, this phone having a 3785 mAh internal battery, yet this pack couldn’t fully charge it. I have heard that there’s factors that could affect that figure heat. How much wasn’t mentioned. It does have a few things going for it, it’s quite slim, adds very little weight to your phone. Your phones still pocketable with it on. I do wish it came in more colors, at least black. I have a black phone, so the white just sticks out like a sore thumb. I hate colors that clash, but in a bind I will still use the pack, clashing colors is better than a dead phone. Im thinking about getting another one with higher capacity, have seen ones with 10,000 mAh, I might try. With packs available now with double the capacity of this pack, I’d probably recommend going with them instead unless slim factor is a priority, then go with this pack as it’s quite thin (see photos)

I absolutely love this portable charger for my iPhone. I have always found it so inconvenient to have a bulky charging block that plugs into my phone. They are always bulky and heavy and take up too much smack in my bag. This MagSafe portable charger is the exact opposite. It’s sleek and small with a thin profile and a strong magnetic that stays attached to your phone. It also charges quickly. It is so much easier to use. I highly recommend this.
