And it's possible to charge multiple devices all at once with this power bank. Read more
I like that this battery pack has both USB-A and USB-C (A out, C is in/out) as well as the magnetic charging for my iPhone. It was $25 when I ordered it, and it's worked well for me around the house and on the go. It's rated for 20W wired output, 18W input charging, and up to 15W on the wireless charging pad. The magnetic function is strong enough that I can put it in my pocket without it coming off. I'd like it if the charge input was highier than output, but I normally use it for the phone so in effect it is. Read more

Now, this is what I would call an "off brand" battery pack. And that does come with some general safety tips I would pass on. I would not leave your device attached to this and walk away for extended periods. I would not leave this attached to the wall to charge after it is done charging for extended periods. If it is giving or receiving power, I would probably not leave it alone for extended periods. I am not saying that is the case with this battery pack, but a lot of these off brand electrical products are... not made with much care or quality in mind. And for battery packs, which can contain a whole lot of energy in a relatively small package, that can result in a rather explosive situation. But with that in mind, it absolutely does work. It did charge my Galaxy S22 Ultra twice and had some power left over so I imagine the suggested amount of mAh is probably around that amount, give or take. It did wirelessly fast charge my Galaxy S22 Ultra with no issues as well. And the four little LED's to show charge level did appear to work just fine. So, with the caveats in mind... this is a perfectly functional, so far, battery pack with wireless charging. Read more
I was looking for a slim power bank that I could charge my phone with on the go. I picked this because it looked nice and slim. The wireless charging works great and quickly charged my phone. The wired connection is faster but both work great. I like that you can charge multiple devices at the same time. For the price this is an amazing battery. Read more
This 12,000 man battery bank is a great choice for iPhone users looking for a convenient on the go charging solution. The magnetic connection is plenty strong and if you have deep pockets this device can easily charge your phone while magnetized to the back of it, perfect for anything where you need lots of battery while on the go. The build quality feels very durable but is plastic so won't handle repeated drops particularly well. However, It is important to understand the limitations of wireless charging - due to the lack of efficiency of wireless charging itself you will get less charges than using the wired ports. Wirelessly charging an iPhone 16 pro max I get about 1.5x full recharges of my device, but when wired I can recharge my phone at least twice - at a much faster rate. This is not a flaw of this power bank but is just the nature of wireless charging. If you're ok with that trade off the wireless charging works just fine, and with two additional ports (USB C, and USB A) for wired charging, this is a exceptional option providing both means of charging your device. I use this regularly for travel and have yet to experience a problem. Read more
