Wireless Portable Charger 30,800mAh 15W Wireless Charging 25W PD QC4.0 Fast Charging Smart LCD Display USB-C Power Bank, 4 Output External Battery Pack Compatible with iPhone 16/15/14/13, Samsung etc

In terms of the device itself, 5 stars. The built in wireless charging means I don't have to wear out connectors on an expensive smart phone, plus just less cable clutter. It charges fast, and stores lots of power. I have not yet done a full capacity test, but based on discharge percentage, it seems to have lots of capacity.Not this is a normal / true wireless charger, just like the other wireless charging pads. Not some kind of proprietary maglock setup. Which is what I wanted.The first one I got was broken... and was obviously a used device that had been put into new packaging. I thought about removing a star for this, but I don't know who to blame. The manufacturer / seller? Did they repackage a return and sell it as new? Was it Amazon? Did they get one back and just chuck it back on the shelf? Other consumers? I suspect somebody had one of these, used it for a while and had a problem, ordered the same one new, and swapped them (the battery showed wear and tear, and the package seal was cut, but the wires will still factory bundled.So somebody screwed up, and I had to return it and get another one, but the replacement works nicely and I like it. I leave it in the car, which has wireless android auto, so it is always charged, then on long trips I can pop it out and have it charge the phone without having to connect a cable to the phone. And I have it there for power emergencies.

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.

This portable power bank is so handy. You can bring it with you everywhere. You can at-least charge 3 devices in this powerbank. This purchase us very useful for me in daily use

Stores a lot of power, but the wireless charging uses more power than it delivers by a large margin. Best to charge your device direct with a cord or expect a lot less out of this than advertised.

I liked it, I always take it with me when I go somewhere on vacation :) it holds a charge well!
