LUCKYDUO Ultra Slim Magnetic Portable Charger 5,000mAh, 0.3in Thin Wireless Power Bank , Compact Magnetic Battery Pack 20W Fast Charging with USB-C, Compatible with iPhone 16/15/14/13 Series

So to start the real measurement of thickness is .355" not .3So even though they stretched the truth as much as possible in the advertising i can tell you this will be my #1 battery bank in my collection by far its soo easy to forget about it on my phone given its thicknessSo build quality seems to be just good enough 99% of people would never notice that you can see through the side just enough to see both the side of the usb c port and the side of the button on itMagnetic strength is as good as you could ask for i can hold just the battery bank and flop my hand around with 0 movement as far as the magnet goesThe auto on feature is dopeAs for charge speed i dont care about that enough to look into it however i can tell you it can keep up with battery usage on my z flip 5 no problem when charging and using the device at the same timeZ flip 5 specific comments so obviously you have to use it upside down like all magsafe power banks. When the phone is closed it sticks up from the top about an inch or so. It also adds just enough thickness to make the phone slightly more comfortable to hold size wise not weight wise.My only issue i have is that the lights on the power bank stay on while your phone is charging since you cant see the back of your phone while using it youre just showing the public that you have some kind of "fancy gadget" that they might want to steal. This is a poor decision if i want to know my battery percentage then i can press the button for it.

what a useful powerbank, can’t go outside without it .

Works good

First, I want to say that this is my FAVORITE battery that I have ever purchased. Its light, its compact, its easy to pack and travel with and it has been a nice "bump" for my phone on multiple occasion. However, on this last charge, which was my 20th cycle for this battery... the battery charged in 1min. At first, I thought this was very strange because of the fact that I thought the battery was empty. In reality, I did not realize that the battery had gone bad. Then, I noticed the battery started to balloon up. (Picture Attached). I'm sad because this battery should've gotten many many many more cycles and just 20. It's never been dropped and I've always taken very good care of it. Maybe I just got a lemon. It would be nice if the company replaced it however. If they do, I will definitely change my review.

This charger is great!!, This one gets a little hot, but nothing to worry about, and it is understood that if it is delivering charge so quickly, it must get hot, the perfect size for easy use, it is perfect

Nice and slim able to use my attachable lens with my phone

It's extremely slim with a great appearance. However, after charging for a while, the power bank feels like it's burning. It's useful during winter, as it can double as a portable heater. lol

Everything I was looking forUltra Slim, Really impressive form factor. I bought it to fit inside a small phone sling's second pocket so that i could insert the phone into the main pocket to wirelessly charge.... this little guy FAST CHARGES through the pocket layer AND my phone's gel case!Perfect to keep the phone topped off for a day. It also fast recharges... satisfying to see the indicator lights quickly refilling.. probably about 20min per 25percent status barFast Charge - 15w Wireless Fast Charge THROUGH gel case AND bag pocket (Samsung Note 8)Top notch product, good value, highly recommended.
