30,800mAh Wireless Portable Charger with 15W Wireless & 25W PD QC4.0 Fast Charging - Smart LED Display USB-C Power Bank for iPhone, Samsung - 4 Outputs & 2 Inputs External Battery Pack (Green) - Perfect for Travel, Camping and Emergency Power Backup

I panicked when my iPhone 8 Plus’s lightning port stopped charging, then I learned that the 8 plus was the model when Apple started including MagSafe charging in it. I purchased this power bank primarily for the size and the magnetic charging capability. When it arrived it was at 34% power, but it was able to get my phone back up to a relatively good power level using magnetic charging much faster than I typically could with a lightning cable.The capacity of the battery is huge, so it took overnight to charge it to 100% via the USC-C input — I recommend that you use a high output brick (eg, 2.1 A output, not 1.0 A like the older bricks are) to get it charged faster. The battery has to be initially on in order for the magnetic charging to start, you can’t just put the phone on it and expect the battery to auto-detect that it’s there when it’s off. I found that it does NOT do magnetic charging of a phone when you are charging the battery pack— this is a minor inconvenience since I can always use the battery to completely charge my phone and THEN plug in the USB-C cable to charge the battery. The digital display gives an exact charge value, and I found that if I had my phone off and let it charge, my iPhone 8 Plus’s battery would go up about 4% for every 1% change in the battery pack’s charge. That theoretically means 4 complete charges before the pack is drained, though I typically don’t let it get that low to find out.The construction of the battery pack seems solid, and although it warms up slightly if you are doing magnetic charging, it doesn’t get hot to the touch. It IS a bit chunkier than most battery packs, about the size of a iphone plus with the thickness of a deck of cards, but I don’t mind that since you’re getting such a huge battery. The unit comes with a tiny USB-A to USB-C cable, so realistically you’ll need your own longer cable to charge it if the brick is more than a few inches from the battery.All in all, I’m very pleased with my purchase. I’ve only had it two days, but right now I recommend it if you are looking for a decent portable magnetic charger for an older iphone or other standard Qi devices.9/24/23 update: Two weeks in and the battery pack is still going strong. One thing to note: I have a non-MagSafe (but thin) Speck case for my phone and it charges through that. There’s no magnetic click so you have to line things up right (basically just flush the edges of the iPhone with the battery), but it charges well. I’m guessing that it might click with a MagSafe case, but I’m just guessing, I don’t know for sure. So if you don’t have a MagSafe case, you need to make sure that the iPhone doesn’t move around while it’s charging wirelessly. I just lay it right on top of the battery as it lies flat on the table and it works just fine. I’m still very happy with this purchase, and can’t believe the price — I saw wireless batteries with 1/8th the capacity selling for more at Target.
