LISEN 0.3‘’ Ultra Slim MagSafe Portable Charger iPhone,5000mAh Wireless Card Slim MagSafe Battery Pack,Europe Vacation Essential Phone Accessories,Magnetic Power Bank for iPhone 16 Pro Max/15/14/13/12

Updated Product ReviewI 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.

I bought this for my husband for Father's Day. The magnets are strong enough to keep it attached to his phone so it can charge his phone while it's in his pocket. It looks nice, easy to use and feels well made. It functions as you'd expect. Just pop it on the back of your phone and you're good to go. 5000mAh is a lot of power for a charger this thin. My husband is happy with it and recommended it to our daughter.

I used this for the first time yesterday. Fully charged, it got my15 from 10-90%, but it was dead after that. So, disappointing that a 5000 mah battery cannot even fully charge a 3350 mah phone once.Per the warnings in the package, it got pretty hot while charging my phone. Will experiment more with the cord and with/without the magnet.The best part is the small size, but I guess that is also its limiting factor.5/30/25 UpdateLisen reached out to me and offered several solutions. After several attempts (on their part) I finally replied and, since the 5000 seemed lacking, I opted for a 10000 replacement. It arrived yesterday and I still have to put it through the paces to see how it fares. For comparison, it is the same profile, but almost just under 2x as thick, and 2x as heavy (figures). The point of this update is to confirm that Lisen customer service is for real.6/1/2025 UpdateI got nearly 2 full charges out of the 10000 mah unit and there is still 1 light on, so I'm guessing 2-2.5 charges worth of power. These were wired charges without using the magnet. Not sure if using the magnet affects the available power. On the plus side, wired charging was pretty fast (maybe 2% per minute?).As I said above, it's 2x as thick, so a little more cumbersome to use with the phone (wirelessly with magnet) but it's definitely doable.

The 5,000 mAh version is close to perfect. Very thin, lightweight, and trivially easy to use. It only charges the phone to 80%, but I'd much rather carry around two of these than the bigger, heavier, 10,000 mAh version. (My main use for these is carrying a spare when I'm travelling and walking around a new city—I've come to rely on maps for that, so I don't want it to fail because of a power issue.)

I bought a different power bank which is 10,000 mah. It is great and it charges much faster but what you sacrifice is the size of the power bank. I ended up returning it. This one is much smaller and lighter. It works great when you are in a bind. You do sacrifice the capacity but I am ok with it. After using it a few times, I prefer the smaller size over the capacity. It is a pain to carry such a big battery in your pocket. The size of this battery is good. It strike a good balance between capacity and size.

Cannot recommend for Samsung phone. Gets extremely hot and only charges the phone about 20% by Wireless charging. I am using it with a short cord it comes with then it fast charges the phone and works well and you can still stick it by magnet to your phone case to keep it in place. Not ideal but better than nothing. Don't know about iphones. They then sent me a different battery which works better for samsung.Samsung recommended by them:https://www.amazon.com/dp/B0DM8LRX4K
