KuulaaMagsafe Battery Pack 0.27'' 5000mAh Ultra Slim Magnetic Portable Charger Power Bank Support USB C PD 20W Fast Charging, Compatible with iPhone 16 Pro Max/15/14/13/12 Mini, Black

It is amazingly thin and I love it. Because of that there is a few qualms that I have with it. It's way too slippery and I'm not 100% of the capacity. It says $5, but I kind of doubt that they were able to fit that much in there, but it's still a fantastic charger if you're looking for something that slips in your pocket easily

This charger is the perfect size—not bulky at all—and super lightweight, which makes it great for tossing in my purse or overnight bag. It holds a solid charge and powers up my phone fast when I need it. I’ve tried a few before that either died quickly or felt like I was carrying a brick, but this one just works. Simple, reliable, and convenient. Highly recommend!

This Kuulaa power bank stands out with its superb design and construction. It's incredibly thin and sleek, featuring luxurious glass-like surfaces that make it comfortable to carry discreetly. The magnet attaches nicely and securely to an iPhone, but its hold is less firm with an iPhone MagSafe case and barely attaches to non-iPhone devices like a Pixel 9 Pro XL.When charging the Pixel 9 Pro XL wirelessly, I observed a rate of about 5W, which is below the claimed 15W Qi2. Wired charging via the included USB-C cable delivered approximately 14W, also below the advertised 20W PD. Wirelessly charging the Pixel from 40% to 80% consumed most of the unit's capacity, confirming its 5000mAh is suitable for about one significant top-off. The power bank itself recharges fairly quickly (around 85% in 1 to 1.5 hours). The unit does heat up when charging, which is expected. It does not get overly hot.Conclusion:If you prioritize an ultra-thin, elegant battery for light-duty top-offs, especially for an iPhone, this might suit you perfectly. However, its performance falls short of advertised speeds for non-iPhone devices, and magnetic attachment outside the bare iPhone is weak. Given these power discrepancies we doc 1 star -its size, design and construction are top notch.

This little gem is thin, beautiful, efficient and adds extremely minimal bulk to the phone while in use. Couldn’t be happier.

Slim and light weight! Love it!

This battery pack is great. It charges by USB-C, while most others still charge by micro-USB, making it way easier to maintain with the cords for most modern phones. It charges up in a couple of hours, and is good to gowhenever you need it.The magnetic attachment is strong, so you don't need to worry about it falling off of your ohone/case when in use. It's very thin for a battery pack, so I could still put my phone in my pocket with the charger attached. It does get warm when in use, but that's normal for all charging devices.The box includes a charging cord, and a suede-like storage pouch to keep the battery pack protected.At 5000 mAh, this will charge my phone (S25 Ultra) one full time one a single charge, and maybe have a little bit left over. It starts itself up right away as soon as its attached, and supports high-speed charging.This is an amazing little accessory. I plan to keep it charged up and ready to use in case of power loss during stormy weather.

Got this since my last one broke, and first thing I noticed was that the magnet was pretty weak and that I had to press the button to get it to actually charge, as my last one just detected automatically. When I went to try it, it seemed to work but when I came back it only charged a couple points and turned off for no reason. Now I have to turn it back on every few minutes even with my phone case off for it to do anything.

I have a Samsung Galaxy S24 Ultra with a magsafe case. Initially, I was impressed with how thin this charger is and how well it grips onto my phone. I was pleased to see that it is also "fast" charging and not just regular. However, after just a few minutes, my phone was getting hot... uncomfortably hot. Touching the charger, it was even hotter. I ripped it off and exchanged it thinking that maybe I got a bad product. When the second one arrived, I guess it wasn't a fluke -- that one got nuclear-hot as well. I tested it on the husband's S22 and it also got unbearably hot. I'm not sure what the issue is... It is advertised that it is for iPhones, so maybe it is incompatible with others brands? Regardless, I don't feel comfortable using it and I don't feel comfortable recommending it to others...
