CarbonMag Magsafe Power Bank Slim Magnetic Portable Charger 5000mAh, Lightweight Carbon Fiber 20W PD Fast Charging, Battery Pack for iPhone 16 Pro Max/15/14/13 Series Black

This connects to my phone through the case very well. I've only had it for about a month so I don't know how well the elastic and the edges will hold up to use/wear over time. Currently, the elastic is very taut. I actually bought this for a dual purpose - one, to hold cards/notes/bits of this size and two, to further protect the glass at the back of my phone. I accidentally dropped my last phone from a standing position in a parking lot and the back glass shattered VERY easily. I figure one more layer to buffer/protect all of the glass in current phones can't hurt. Great value for the money, magnet strength is strong, fits great and functions as it should.

The color and size are perfect. It is very slim and light weight so I can barely tell it’s on my phone. The strength of the magnet is strong and durable so I can never worried about it falling off. I can charge my phone more than 1 full charge which for the price, I’m very satisfied with

It’s definitely better than the original Apple charger. The only thing is, I wish both sides were made out of carbon fiber. In reality, only one side is made out of carbon fiber, and the other side, which is not gets a lot of scratches as you send a photo.

After about 2 months, it seems to no longer be able charge my phone. It charges itself just fine, the power button activates fine but my phone no longer charges from it. Strange because my other charger from the same company (Sharge IceMag 2) that I ordered slightly before still works perfectly.Just disappointed because I love the product design and performance leading up to now and particularly love the other product I’ve ordered from Sharge.Maybe just worth keeping note of.While I’m not sure they check these reviews, if the company somehow makes this right, I’d of course be quite grateful and willing to update my review.

Really thin little battery pack great for throwing in a bag. Gets warm charging, but not enough to be concerned. Fits fine on my iPhone Pro Max, but too big and sticks out on my wife’s iphone Mini. Really enjoyed using it over the last few weeks to add a little bit more charge.

This power bank is nice and thin, nice and light, and changes my Pixel 9 quickly. I love it!

Charges S25 ultra with case fully, Slimmer than other designs on the market. With correct case, this holds better than the anker magsafe charger.

I really wanted to like this item, but I was sadly let down. The battery pack is as light, compact, and even as beautiful as advertised, but its performance was lacking in terms of charging speed, capacity, and safety. When using the battery with an iPhone 16 Pro Max, it would only charge from 30% to around 80%, and quite slowly at that.Despite this, I continued to use the battery pack for a few more cycles until its charging port melted while I was using a reputable standard USB-C cable and wall plug. I had used the battery pack for a total of fewer than five complete charge cycles before it nearly burned out. I ultimately requested a refund.
