LISEN Qi2 15W Ultra Slim MagSafe Battery Pack,5000mAh Fast Charging MagSafe Power Bank Slim Wireless,Slim Magnetic Portable Charger,Magnetic Power Bank for iPhone Air/17/16/15-12 Series,Gifts for Men

Works excellent! I'll throw it on my phone and barely feel it in my pocket. Charges fast and does not get hot. The slimness and portability make it a very great charger to keep in the car or at the office. Stays attached firmly with strong magnets.

Very happy with my purchase. Does exactly what I want it to do. The magnet strength is perfectly strong, and charging speed is what you'd expect from a wireless charger. I like that it's slim enough to keep on my phone and I am also able to turn off the powerbank in case I don't want to charge it at that moment. The quality feels great, and I haven't felt it get hotter than other powerbanks I own. Very well designed!

I chose this MagSafe battery pack because I wanted a slim, magnetic charger for traveling that would be easy to carry and doesn’t add much bulk to my phone. The magnetic connection is strong and snaps into place securely, and the slim profile makes it comfortable to use while charging. It’s convenient for on-the-go top-offs and short trips, and the wireless charging works as expected. Battery capacity is modest, so it’s best for extending battery life rather than a full recharge. I wanted to give it 5 stars, however, it did get warm/hot at times while charging my phone. Other than that small criticism, it works great. I brought it with on a recent trip and it was super handy! Overall, it’s a sleek, portable power bank that’s easy to use and fits well in a small purse or pocket.

I really like this wireless MagSafe phone charger! It's everything it says it is. My Samsung S25+ days is receiving "Fast wireless charging", as seen in my pictures. I tried two different testing devices and they're showing a peak of 17 watts wired charging. It's so easy to use, just stick it to your MagSafe phone case. I like that it stays stuck to my phone case very well and it even has the extra little dash that keeps the charging from rotating, so it keeps a constant charge (a problem I've had with other wireless chargers, frequently disconnecting/reconnecting). The charger itself looks very nice and feels like it's great quality. I really like that it has a battery meter to let you know what the current level is. It's thin and hardly noticeable on the back of the phone. It actually feels just like my minimalist wallet/card holder and fits in my pocket just fine while charging. While it does feel a little warm to the touch when charging my phone, it does not feel hot or concerning at all. So I'm thoroughly enjoying this charger and how it relieves my battery anxiety on those days I use my phone more or longer than usual. It pretty much doubles my battery capacity. I can also stash this charger almost anywhere. Currently listed at $30, I think it's a great value and it has to be the best slim charger available right now.

I finally found a MagSafe power bank that doesn’t feel like I’m strapping a brick to the back of my phone! I’ve been using the LISEN Ultra Slim 5000mAh for a bit now, and honestly, it’s exactly what I was looking for. The first thing you notice is how slim and sleek this thing is. It’s light enough that you can actually keep using your phone one-handed without your wrist getting a workout. The color matches my phone case well and has a premium, high-end finish that doesn't feel like cheap plastic. The indicator lights are subtle and don't draw attention. The MagSafe connection is very effective. It snaps right into place and stays there—using it during calls and in my pocket it hasn't slipped off once. A big concern with these wireless chargers is usually the heat, but I really haven't felt any "phone-melting" temperatures and is still comfortable enough to use. In terms of actual performance, I can typically charge my iPhone 13 Pro Max from 35% - 95% in about 2 hours with ongoing occasional surfing and phone use. There is still 1 light of charge left on the battery. Smaller batteries and newer phones may vary from my experience. Final Thoughts I’m really happy with this purchase. It’s perfect for those long days when you’re out and about and don't want to hunt for a wall outlet. I've stopped carrying my 20,000mah brick on day excursions and my bag is much lighter for it. I’m actually thinking about grabbing a few more to gift to friends and family.

This is the fourth of these that I have. This is the thinnest and the strongest one I have. It looks good with its silver cover and grabs the back of my phone very well. I do not think you will be disappointed with it.

My new Lisen battery works better than expected! Previously I was using a magnetic charger by Anker. It works fine but is a brick compared to this Lisen! I can actually attach it and keep it attached while in my pocket (with others, I have to put in a separate pocket as they are so thick that it’s uncomfortable). I also appreciate how well the magnet works and that it doesn’t get hot in my pocket. I’ve always had an Amazing experience with thier customer service and they have never disappointed me.

I just upgraded to an iPhone 17, I absolutely Love that this is magnetic! No cords, no holding two slippery things at once! So easy and sticks tight! Quick charge too👍🏻👍🏻

At first glance, the power bank looked promising, and after putting it into regular use I can say it has a lot going for it. I’ve been using it mainly as a slim, magnetic top-up charger for a smartphone during days out, travel, and long periods away from a wall socket, where cables can be inconvenient. The ultra-slim design is immediately noticeable. It sits almost flush against the back of the phone and does not add the usual bulky feel associated with portable batteries. In real use, the magnetic alignment is strong and precise, snapping into place cleanly and staying put in a pocket or bag without sliding off. Wireless charging starts reliably every time, and the Qi2 implementation feels efficient, delivering a steady charge rather than pulsing or cutting in and out. Heat management is also well controlled. Even during higher-power wireless charging, the unit only becomes mildly warm, which suggests the internal temperature regulation is doing its job properly. Charging performance has been consistent and predictable. The rated capacity translates realistically into a partial top-up rather than a full recharge, which is exactly what this type of slim power bank is designed for. It is ideal for extending battery life through the day rather than replacing a high-capacity charger. Wired charging is quicker when needed, and the power bank negotiates output cleanly without triggering overheating warnings on the phone. Build quality feels reassuring, with a rigid shell, clean edges, and no creaks or flex when handled. The surface finish resists fingerprints well and feels durable enough for everyday carry. There are a couple of minor drawbacks worth noting. Because of the slim profile and limited capacity, it will not fully recharge larger phones from empty, so expectations need to be realistic. It also works best without thicker or non-magnetic cases, as alignment and efficiency can suffer otherwise. That said, these are trade-offs that come with prioritising thinness and portability. Overall, it has met my expectations and works well as a compact, reliable power bank for short top-ups when on the move. Despite the minor limitations, it feels well made, thoughtfully designed, and suited to anyone who values slimness and convenience over maximum capacity.

Ich bekam im Rahmen des Amazon Vine Programmes diese „LISEN Ultradünne MagSafe-Powerbank, 5000 mAh“ zum Test angeboten. Als Nutzer eines iPhone 15 Pro eine sehr praktische Energiereserve für unterwegs. Daher habe ich sie gleich angefordert. Angekommen ist sie in einem Pappkarton. Drinnen sind neben der Powerbank selbst noch ein separates USB- C Ladekabel und eine mehrsprachige Bedienungsanleitung auch in deutsch. Nach dem Auspacken habe ich die Powerbank vollständig geladen und dann mehrere vollständige Ladezyklen durchlaufen, jeweils mit Messung der abgegebenen Energie in Wattstunden wie üblich, wenn ich Powerbanks teste. Die abgegebene Leistung per USB- C Anschluss lag im Schnitt bei 16Wh. Angegeben ist die reine Akkukapazität ohne Verluste mit 18Wh. Der Hersteller gibt eine „rated capacity“ von 3000mAh an was umgerechnet 10,8Wh entspricht. Die tatsächliche gemessene Effizienz liegt bei etwa 89%. Das ist ein Spitzenwert für solch eine kleine Powerbank und weit über dem Durchschnitt. Ich vermute, dass sich die sehr konservative Angabe der „rated capacity“ auf das Laden per Qi Ladepad bezieht und nicht wie angegeben auf das entladen bei 5V/2A per Kabel. Beim induktiven Laden sind die Energieverluste technisch bedingt größer als beim entladen per USB-C. Leider kann ich die abgegebene Energiemenge per Qi Ladepad nicht messen um dazu mehr sagen zu können. Von den reinen Messwerten abgesehen lädt die Powerbank mit maximal 18 Watt und entlädt mit um die 22 Watt, was für Smartphones und Tablets ausreicht. Die Powerbank hat nur einen USB-C Anschluss. Dieser wird zum Laden sowie Entladen genutzt. Auch ist es möglich gleichzeitig ein Telefon per Qi drahtlos zu laden und die Powerbank währenddessen per USB Kabel zu laden. An der Verarbeitung kann ich nichts aussetzen. Das Gehäuse ist aus Aluminium, welches gleichzeitig als Kühlkörper dient, denn beim induktiven Laden wird doch relativ viel Wärme freit. Fazit: Eine kompakte Qi Powerbank für das Nachladen von Kleingeräten unterwegs, die hält was sie verspricht. Ideal für aktuelle iPhones wie es bei mir der Fall ist. Von mir daher 5 Sterne und eine klare Kaufempfehlung

Isn't it annoying that the phones of today, due to complexity, drain batteries sooooooo fast? I remember having a Motorola StarTac that lasted for a few days and now, my iPhone is on charge every night. But charging it isn't easy to do when you're on the move, like on holiday or whatever and it always dies on you when you're on the train (or in your car in the middle of nowhere, should you be in a horror movie). So having something to supplement the power is smart/handy. This little - and it is pretty little - device just attaches to the back of your phone magnetically. I use MagCharge cases so it just attached nicely. It's thinner than the iPhone and not as wide/tall obviously otherwise it would cover the cameras. It also arrived with a slight charge, but only around 20-25%, so charging it up took like an hour (the cable showed a power draw of around 18w - I used my own rather than the one in the box) and didn't get hot while charging, a bit warm but nothing weird. The manual said press the button on the side to turn on, 2 presses for off. Honestly, just attaching it to the phone made it power up, no need for a button press, although you'd wanna switch off when you detach. The only criticism is that it says it's "5000mAh" but rated as "3000mAh". It might be me, but the back of the item only shows 3000. Saying it's 5000 but rated as 3000 feels a bit like saying "My car is a Porsche, I know it has a Mini badge on it but it's really REALLY a Porsche". so.....I'm ignoring the 5000 - it says 3, it's 3. Hence the 4 stars as it feels dishonest to say something is something it doesn't show as being. But it works fine.

LISEN Ultra Slim MagSafe Power Bank. 5000mAh (Rated Capacity 3000mAh). Qi2 15W Wireless Slim MagSafe Battery Pack. Magnetic for iPhone 17 Pro Max Plus Air 16 15 14 13 12. Very pleased with this Magsafe Battery Pack from Lisen. Build quality looks very good and up to the job. I really like pretty much everything about this Battery Bank. It’s small and neat and easy to use. It offers (in my humble opinion) the right size / capacity for everyday emergency use or just a quick top up. Its sheer size means you are likely to have it with you unlike some of the other fairly large bricks I have had (and not used!) in the past. First thing you are going to want to do out of the box is give it a full charge. My pack arrived with 1 LED illuminated so it was pretty much empty! Plugged it into my fast charger and it was up and running, fully charged in approx 1 hour. Charging your Phone is fast and efficient. 2 ways to charge, either wireless Magsafe or USB C (Cable supplied). USB C is faster but you may not have a cable with you? Either way you are pretty much covered. When in use via Magsafe I found the Magnet strength was very good. Also both Phone and Battery Pack remained relatively cool during the charging process, ensuring a fast, efficient and safe way to charge up / top up your Phone. All in all as I mentioned earlier, I am very happy with this Battery Bank from Lisen. It is excellent quality both in overall build and quality of components. At time of order the price was £33.99 which I think is good value for money for this quality product.

Ich habe mir die LISEN Ultradünne MagSafe-Powerbank mit 5000 mAh als kompakte Notlösung für unterwegs geholt und war vor allem vom extrem schlanken Design überrascht. Mit rund einem Zentimeter Dicke trägt sie kaum auf, hält magnetisch sehr sicher am iPhone und passt problemlos in die Jeansjacke oder sogar ins Sakko. Also Konzert und Arbeitstauglich. Verarbeitung und Haptik wirken hochwertig, nichts klappert, und das kabellose Laden funktioniert zuverlässig. Die Magnetkraft ist stark genug, dass das iPhone (in meinem Fall ein iPhone 17 Pro) auch in Bewegung sauber an Ort und Stelle bleibt. Kapazität realistisch betrachtet Wichtig ist allerdings, die beworbenen 5000 mAh richtig einzuordnen. Der Hersteller selbst gibt an, dass effektiv nur rund 3000 mAh nutzbar sind. Das liegt daran, dass Powerbanks ihre Zellkapazität meist bei ca. 3,7 Volt angeben, Smartphones jedoch mit rund 5 Volt geladen werden. Bei der Umwandlung entstehen Verluste durch Elektronik und Wärme. Kurz gerechnet: 5000 mAh × 3,7 V = 18,5 Wh Energieinhalt Teilt man das durch 5 V Lade­spannung, bleiben theoretisch etwa 3700 mAh. Zieht man typische Umwandlungsverluste von 15–20 % ab, landet man realistisch bei ungefähr **3000 mAh**. Das ist also kein Trick, sondern Physik. In der Praxis reicht das je nach iPhone eher für einen ordentlichen Zusatz-Boost als für eine komplette Vollladung, besonders bei größeren Modellen. Qi2 und Ladeleistung Die Powerbank ist Qi2-zertifiziert, also die neue Generation des kabellosen Ladestandards. Qi2 basiert technisch auf Apples MagSafe-Prinzip und sorgt durch die exakte magnetische Ausrichtung für effizienteres Laden, weniger Energieverluste und kontrolliertere Wärmeentwicklung. Theoretisch sind hier bis zu 15 Watt kabellos möglich. In meinem Eindruck lädt sie ordentlich, aber nicht außergewöhnlich schnell, und beim kabellosen Laden wird sie spürbar warm. Laut Hersteller reduziert sich die Ladegeschwindigkeit ohnehin ab etwa 75 Prozent Akkustand, was bei Powerbanks dieser Klasse üblich ist. Mit Hülle sollte man aufpassen, da nicht-MagSafe-Cases zusätzliche Erwärmung verursachen können. Fazit Unterm Strich sehe ich die LISEN-Powerbank als solides, sehr mobiles Zubehör für kurze Einsätze, Meetings, Reisen oder als Backup im Alltag. Das ultradünne Design und die starke Magnetverbindung sind klare Pluspunkte. Wer allerdings mehrere Geräte laden oder sein Smartphone regelmäßig vollständig aufladen möchte, sollte eher zu einer stärkeren Powerbank greifen. Für Minimalisten und stilbewusste Nutzer, die eine elegante Notreserve suchen, passt dieses Modell dagegen ziemlich gut.
