    This is so inexpensive because it doesn’t stay on your phone. If you want to walk around with your phone I would choose something else. If you leave it stationary then it’s just fine

      Hi KathyH,
      Thanks for sharing your experience. This power bank is designed for stationary use with magnetic alignment, so movement can cause it to detach. If portability while charging is important, a stronger MagSafe grip or a wired power bank would be a better choice.

      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:

    It's Like Fake Qi Charging

    It looks cool and you think it's gonna be great (small, lightweight) but it doesn't deliver. The Qi charging doesn't work through the back of my case which works fine on my plugged in night charging stand. Plus, I'd said when you can get it to charge, it only charges about half as fast as a "fast charging" plug-in transformer. And even then I'd only trust is to charge maybe from 60 to 100%, not a fully discharged phone, no way. Disappointed. Not dependable.

      Hi icetime,
      We’re sorry the charging performance didn’t meet your expectations. Wireless Qi charging can be slower than wired fast charging, and thick or non-MagSafe cases often block proper alignment, reducing efficiency. For best results, use a MagSafe-compatible case or remove the case entirely, and ensure the power bank is fully charged before use. If you suspect a defect, please reach out here:

      Hi IPHONE11,
      Sorry to hear the charging speed didn’t meet your expectations. The 5,000mAh power bank provides standard wireless charging, which is generally slower than wired charging, especially for larger devices like the iPhone 16 Pro Max. For faster performance, using a wired connection or a higher-capacity power bank (10,000mAh or more) is recommended. If you believe the product is defective, please contact our support team for assistance or a possible replacement:

      Hi Phyl,
      Sorry to hear about the slow charging and sensitivity to movement. Wireless magnetic chargers can stop charging if alignment shifts, which is common with slim designs. For a more stable experience, try using a MagSafe-compatible case or keep the phone stationary during charging. If the performance feels defective, please contact our support team for assistance:

      Hi DianeK,
      Sorry to hear the magnet strength and charging performance didn’t meet your expectations. The 5,000mAh capacity typically provides about one full phone charge, so it may not always reach 100% if the phone is in use during charging. For stronger magnetic hold, ensure you’re using a MagSafe-compatible case or no case at all. If you believe the product is defective, please contact our support team for assistance or a possible replacement:

      Hi Janin,
      Glad to hear it works well for emergencies! The slower charging speed is common with wireless magnetic chargers compared to wired connections. For faster performance, you can use the USB-C port with a cable instead of wireless charging.

      Hi EnyD,
