    Its nice to slap this battery on and go. When you cant plug in or just prefer to be cordless, this battery is great. Charge while using your phone. Very convenient.

    Thicker than I expected but still comfortable to hold the phone with it on. Also gets warm but not uncomfortably so, so that's nice.

    If you are using it wirelessly, your phone and the battery will warm up very quickly so I would recommend just plugging it in

      Hi Konnor,

      Wireless charging can generate noticeable heat because energy is transferred through coils, and the temperature can rise faster when using magnetic alignment. To help reduce heat during use, here are a few tips:

      .Remove thick or metal phone cases while charging.
      .Charge in a cool, ventilated area and avoid direct sunlight or enclosed spaces.
      .Try not to use your phone heavily (gaming, streaming) while it's charging wirelessly.
      .Try not to wait until your phone battery is very low before charging, as low battery levels draw more power and create additional heat.

      If the power bank ever becomes too hot to comfortably touch, please stop using it and contact support:

      Hi ErmH,
      Thanks for sharing your feedback. The slim design of this power bank can make the magnetic hold less strong compared to thicker models, especially if used without a MagSafe-compatible case. For better stability, we recommend using a MagSafe case or minimizing movement during charging. Your input is valuable and will help us improve future designs.
