Review: Update - Notable Improvements - Updated Product Review I was not totally satisfied with the original purchase for a number of reasons. However, I also wasn’t totally dissatisfied with it either. Its biggest benefit was always its strongest selling point, the fact that it is ultra slim. First, I’d like to say thank you to Bonnie and her excellent customer service. Most companies sell you something and walk away. LISEN on the other hand actually listened and was willing to address my concerns. Obviously I was unaware there was an updated version of the product I received. The company’s solution was to replace the purchase with the newer version. They also offered a full refund, but I was more interested in the product itself and its slim profile. What has changed? One concern was the original purchase got warmer than I liked while charging my phone. This new version DOES NOT warm up while charging my phone. LISEN has resolved this issue. The original purchase charged my phone slower than I liked. This has been resolved in the newer version. The original purchase did not charge my phone completely. As Bonnie pointed out and she is correct, I own an iPhone Pro Max. The 5K version of this device or any other brand is not capable of giving the larger battery in the Pro Max a full charge, but it will get you 80% of the way there (typically good enough). If you’re looking for a full charge on the Pro Max, purchase the larger 10K version of the LISEN (full charge plus). The original purchase took a long time to recharge. This issue has been resolved in the newer version. It recharges at least as fast as advertised. My final issue with the original purchase was the MagSafe connection. The primary connection is strong and that was true on the original purchase. Not falling off. My issue was and still is that it can twist easier than I’d prefer. If you’re familiar with the MagSafe design, it has the circle and line on the bottom. The line on the bottom prevents a device from twisting or turning. This portion of the magnet could still be improved, but is a minor concern. Updated conclusion. The newer version is a solid product and delivers as promised. And again, its best feature is how slim it is (unmatched in the industry, at the moment). Less bulk, less weight. They have resolved the biggest issues, but could improve it further, per my last comment. In all, I’d give it 4.5 stars, but that is not an option. Because they addressed the most pressing issues in the new version, it gets 5 stars.
Review: Replaced with upgraded model and working flawlessly. - August 6, 2025 update: Just making an update because a company that stands behind their products like LISEN does it needs to be noted. They reached out to me to replace the device I purchased with an upgrade device and I'm happy to report that the replacement device is on par with the specifations described. There no overheating and I was able to get a full charge on my Samsung Galaxy Note and still has enough power to top it off. Can't speak highly enough about the excellent customer service I got from Mobe, she went above and beyond to make sure I was happy with the upgraded device and due to their outstanding customer service I will not hesitate to purchase my next device which is the wireless car charger, I'm confident that if there any issues, Mobe customer service rep, will make it right. When I saw this Lisen charger I was intrigued on how thin it is and it was exactly what I was looking for, a charger that was thin enough to put in my pocket without the extra thickness that must have, so I put it to the test, magnet strength is amazing, aesthetic wise it looks classy and not overly flashy with just 4 led dots showing battery strength, thickness is perfect at just .03 inches, but unfortunately after about 5 minutes into charging my cellphone the unit gets too hot making it uncomfortable to be on a phone call for too long. I really wanted it this charger but performance wise it's just not cutting it, hence why only 2 stars.

### ⭐⭐⭐⭐ Good product - Decent charging speed, great size
*by E***E on September 25, 2025*

**UPDATE** increasing my review to 4 stars. After my initial one star review the company reached out and took me through a couple troubleshooting steps and then sent me a free replacement and didn’t ask me to return the defective one. The new one does a much better job of charging. That kind of customer service is so refreshing in today’s day and age!!! The charger is fairly slim and attaches with a decent magnetic connection. The problem I have with it is that it advertises that it does fast charging but when connected via MagSafe to my iPhone 15 Pro Max it only does slow charging. It is so slow that my charge actually decreases while the battery is attached instead of increasing, even if it’s just sitting on my desk and not being used. Completely useless.
