4.0 out of 5 stars Charging speed

A.a. · 2 June 2025

The magnet strength is excellent hasn’t fallen off and I don’t think it could fall off.The charging speed is a little slow, but still gets a full charge into the phone,It’s easy to charge and very portable, I use mine while my phone is in my pocket.The speed of the charger is the only thing that lets it down

5.0 out of 5 stars Great value for money, definitely recommend

Light, well made and stylish. Magnets are strong even through a case. Very pleased and great value.

5.0 out of 5 stars It does what’s it says!

M.A. · 12 June 2025

Charging speed is quick, slimline unit and magnet is strong so it does what is says in the tin. I actually bought 3 but noticed one had different colour charge lights from the others and what was indicated in in the manual. Contacted Lisen and they have replaced free of charge with new one. So great service also!

4.0 out of 5 stars Slim and great on iPhones

k.u. · 1 June 2025

Very slim which is the reason why I went for this item, sticks on well on the back of an iPhone, only negative I’d have to say is battery capacity isn’t the 5000ah as described, could be wrong but doesn’t give an iPhone a full charge, still happy with my purchase

1.0 out of 5 stars Not as advertised

A.w. · 15 June 2025

Doesn’t hold the charge like it advertises, it does magnetically stick so that is good but the charge that trickles thought, your using your phone at the same speed as charging your phone so no improvement at all, also heats up a lot. Making your phone hot too.

3.0 out of 5 stars Compact, good magnet, but lacks charging power.

A.R. · 13 June 2025

Its ok. 1st use I found that it overheated and took a long time to charge. At the time it was in my pocket or being used.2nd time I did a controlled test. Cool room and no usage. Went from 40% to 95% on my phone (samsung s25 edge) in approx 2.5 hours before the pack was depleted.I like how compact it is, and magnet strength is excellent, but for peace of mind, Id like to be assured I can at least get 1 full charge from the battery pack. It seems that, Id get 55% charge in optimum conditions.

Very Strong Magets

A.W. · 21 June 2025

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.

コンパクトで持ち運びしやすい

カードサイズで厚みもなくバックの小ポケットにしのばせやすく、旅行に限らず常に持ち歩けていざという時の備えとしても使えそうです。マグネットで充電できるのでケーブルレスなのもとても良いです。

Update - Notable Improvements

b. · 16 March 2025

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.
