Review: Great charger! - This magnetic charger has been a great purchase. It attaches securely to the back of my iPhone, so I can keep using my phone while it’s charging without dealing with cords. It’s slim, lightweight, and perfect for travel or when I’m on the go. It charges well, and I’ve been very happy with it. Highly recommend!
Review: So small and so convenient - So slim. Good power even through the case on my iPhone 14. Wish it held position just a little tighter. It tends to slide enough that charging stops in my pocket. Maybe without a case that wouldn't happen. It still keeps the phone from dying, and you can reattach it easily to take pictures and make calls. Also nice that I can stick it to the fridge and grab it on the way to the car.

A: Compatible with iPhone 17/16/15/14/13/12 series supports 15W charging.iPhone 16e supports 7.5W charging and MagSafe-compatible phone cases

A: It has peak 15W Qi2 fast charging with dynamic power range regulation. Real-time adjustment ensures safe, cool and optimized charging for your device.

### ⭐⭐⭐⭐⭐ Great charger!

### ⭐⭐⭐⭐⭐ So small and so convenient
*by J***S on August 4, 2026*

So slim. Good power even through the case on my iPhone 14. Wish it held position just a little tighter. It tends to slide enough that charging stops in my pocket. Maybe without a case that wouldn't happen. It still keeps the phone from dying, and you can reattach it easily to take pictures and make calls. Also nice that I can stick it to the fridge and grab it on the way to the car.

### ⭐⭐⭐⭐⭐ luxury at a fraction of the price
*by M***W on June 2, 2026*

I'm not going to knock this thing at all. From where I'm standing, it's luxury at a fraction of the price. Just slap it on your phone when it's dead and let it top off? YES PLEASE. And did I mention it also works with Android? Granted, you'll need a MagSafe case for your Android phone. I've got a Z Fold 7 and it works perfectly with it. I don't have hard numbers, but here are the basics. You charge it via USB-C, and you've got options: charge your phone through that same USB-C port, or stick it to the back of your phone and let it charge wirelessly. The only thing I'm still a little confused about is whether you need to turn it on before slapping it on. Sometimes I put it on and it automatically kicks in and charges, and other times it just doesn't. A little inconsistent there. It's also super versatile. I even use it to power the cooling fan on my ZV-E1 in the studio. Battery life is decent, charging speed is okay, and the magnetic connection is pretty strong. It has slid off my phone in my pocket on occasion, but it's no big deal. I just keep it next to me while it's charging rather than in my pocket, which also helps because it does tend to get a little warm if you don't give it proper ventilation. So, 5 stars. It's affordable, genuinely versatile, and dead simple to use. A couple of small quirks with the activation and the heat, but nothing that would stop me from recommending it.
