    Great battery pack! The 5,000 mah is a little small, because you do lose some in heat due to wireless charging. It charges my S25 FE from 10% to 70%. It does get a little hot and throttles after a bit but is still a good deal at 13$. I use a magsafe case on my samsung to have full compatibility.

      Hi lexa,
      I’m sorry the power bank is heating up quickly during use. Some warmth is normal with magnetic wireless charging, but overheating isn’t expected and can affect comfort and performance. Since the unit is charging your phone but getting too hot, our support team can help check whether your device may need repair or replacement:

    Great to have for camping, work, anywhere you don't have access to usb power. Just remember to keep it charged. It's best to use before you have less than 20% battery life left

    Purchased two of these when on sale. Arrived quickly and they are great to have and carry around. Just attach to MagSafe phone cover and it provides power to the phone. Very Satisfied. Not large and bulky like some PowerBanks.

    A slim design. I bought the 10,000 version and this version. Even though this one is only 5,000… i like it because if the size. In my opinion it is slightly less than half the thickness of the 10,000 version. It is at least half the thickness as you could imagine.

      Hi Richardw7,
      We’re glad you appreciate the slim design! The 5,000mAh version is indeed engineered for portability, making it ideal for snug pockets while still delivering reliable power. Great choice for on-the-go convenience!

    The magnet holds strong and it charges relatively quick especially on older iPhone models, namely iPhone 13. Product comes with its own USBC charging cable and it does charge up somewhat slow but its a tradeoff.

    I got this charger on sale for like $12 so i don't want to complain much. Ive used other magnetic chargers and they stay on pretty well. This one always goes askew. I use it at work where im constantly taking my phone in and out of my pocket, so it's a little annoying. However, the charger itself works pretty fast. i usually start using it around 20 or 30% and find it gets all the way to 100 without overheating and pretty quick.

      Hi xtinaaa,
      Thanks for sharing your experience. We’re glad to hear the fast charging works well! Regarding the magnetic alignment, this model uses a slim design which can make the hold less firm compared to thicker magnetic chargers, especially with frequent movement. If you’d like a stronger grip, using a MagSafe-compatible case or minimizing movement during charging can help.

    Have only used the MagSafe power bank a few times, but it works flawlessly. I feel like it charges quickly and I am able to get more than a full charge out of an iPhone starting at about 20%.

    Charges my phone up and its very compact. You can connect the USB-C through it while charging as well so you only need one cable. The only downside is that it may not be compatible with your magsafe case depending upon the size of the camera bump.
