LISEN 0.3‘’ Ultra Slim MagSafe Portable Charger,5000mAh Wireless Card Slim MagSafe Battery Pack iPhone 17 Air Accessories,Magnetic Power Bank for iPhone 17 Pro Max Plus Air/16/15/14/13/12，Pearl

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.

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.

**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.

Great portable battery. Attaches to phone magnetically so losing it not an issue. Clip to your phone and charge whatever you need to. GREAT BATTERY.

Fast charging easy to use and so far after trying a few different brands, it has been the slimmest one at an affordable price if you catch the sale. It fits well in small bag and can charge the phone to reasonable amount so it’s been great for emergencies and for traveling. Only down side has been bc it charges the phone quickly it can get hot and will stop charging phone until it cools to normal temperature. This isn’t unusual though, it’s been the same with other brands with similar functionality. Instructions do advice using the battery pack without phone cover to prevent overheating as well. We ended up getting another one a few months later and while it’s advertised as same as the first it was slightly thicker. So maybe a newer version? Also had an issue with the power button but lisen remedied it by sending me a replacement quickly without hassle. Response was quick and simply asked me to send a quick video to document the issue. So great customer response as long as you are within warranty period.

excellent and light weight. Easy to carry around. works very fast in charging.

This is a really great power bank, sticks really really good to the phone and charges it very quickly. Real thin and not bulky. A great buy and easy to carry

謳い文句通り「薄い（ケース付きのiPhone 15 Pro Maxより薄い）」「小さい」「軽い」ので、いつでも付けていられるのがありがたいし、これで3,000円なのもうれしい。 ただ、バッテリーの劣化してきた iPhone 15 pro max だと、使用しながら無線充電しているとかなり熱くなる。また無線充電ではほぼ使用して消費する電流と同じくらいしか充電できないようで、そういう時にはiPhoneにくっつけながら付属の30cmケーブルを繋ぐと無線充電がカットされて有線充電に切り替わるので、急速充電できるし充電効率も高くモバイルバッテリーの残量の減りも少なくて済むので便利だ。 また、サブ機のMotorola razr 50sでもしっかりと背面に磁石でくっついてワイヤレス充電できたので、たいていの無線充電対応機でも使えることと思う。折り畳んだ状態では本モバイルバッテリーの方が大きくてはみ出てしまったが。 これまで分厚い10,000mAhのMagsafe対応のモバイルバッテリーを使っていたのだが、先日の旅行で iPhone 15 pro max ごと落としてしまったので、取り回しのよい薄型モバイルバッテリーを求めて購入したワケだが、これで落下事故も減らすことができそうだ。

Yo les voy a ser honesto, esta batería sale muy bien pero con este no logras cargar tu celular al 100% yo me fui con la idea de que al ser de 5,000 y mi s23 ultra tiene batería de 5,000 pensé que la cargaría sino completa tal vez un 80% La realidad es que carga alrededor de un 40% La razón principal por la que yo la compre es por la delgadeza y en eso cumple perfectamente Para mi esto es un salvavidas enorme ya que me suele suceder salir de mi casa con un 20% y al quedarme literal 1% me acuerdo y pongo la pila y no se apaga puedo estar usándolo al 1% y normal, eso es importante para mí Las 5 estrellas es por la delgadez y que cumple su función principal que es extender la batería de tu celular

Excelente, muy delgada y sin problemas para cargar mi teléfono

phon15PROで使用。 意外と熱を持ちますが、充電機能はOKです。 薄くて邪魔にならないので良いと思います。
