Let me start by saying this little guy has been a game-changer for my iPhone 12. The magnetic attachment is seriously strong - I've accidentally flung my phone across the bed trying to remove it (don't worry, both survived). Unlike cheaper alternatives that randomly disconnect, this stays put whether I'm taking selfies or juggling coffee.

The compact size is perfect for pockets, but don't expect lightning-fast charging. From 60% to 95% takes about 90 minutes in my experience. It's more of an emergency booster than a full charger - think of it as your phone's energy bar when the battery hits red.

Yes, it gets warm - sometimes reaching 134°F according to my temperature gun. But here's the thing: the heat stays in the battery unit itself rather than transferring to your phone. The built-in thermostat cycles between heating and cooling, which actually shows thoughtful engineering.

Works surprisingly well with thick cases too! I installed the included metal ring on my bulky OtterBox using a clever positioning trick: I first found the sweet spot where charging initiates reliably, then permanently attached the ring there. No more alignment guesswork.

The matte finish feels premium, though be warned - if you drop this, the loud 'clank' might startle your neighbors (ask me how I know). The two-way USB-C port is convenient for topping up the power bank itself.

Perfect for travelers who need just enough juice to last through airport layovers or important calls. While it won't fully charge newer iPhones with larger batteries, that 50-80% boost has saved me countless times when outlets were nowhere in sight.
