      Hi GamerYes,
      Thanks for sharing your detailed feedback! We’re glad the wired charging works well and the capacity meets your needs. Wireless charging can generate extra heat due to energy transfer and magnetic alignment, but it should not feel unsafe. If the overheating seems excessive, please stop using it wirelessly and contact our support team for assistance:

    I purchased this due to TSA changing requirements. It is lighter in weight. It is limited to charging two devices at one time. THE NICE thing is its charging pad in case your charging port is damaged or you just don't want to plug it in. This is the only reason I gave it 4 stars and not 5.

    It is thicker than I thought but I like that it magnetizes to my iPhone MagSafe and holds tight. Like that I won't have to plug anything in. Fits perfectly behind my phone. Haven't needed to use It yet but will soon on a trip. Will come in very handy.

    After my $15 dollar mag charger broke i used this battery as my main go-to. It has a usb-c fault were the connection gave in, have to shift the connection a bit every time, otherwise it would b a solid 5 star. Charges a bit slow though.

    Good battery life but the magnets don't hold that great. For the price it's fun but don't expect the magnets to stay on in your pocket. All good for a top up though

      Hi NickP,
      Thanks for sharing your thoughts! The magnetic hold can vary depending on the phone case thickness and surface texture, so it may feel less secure in a pocket. For best results, try using it without a case or with a MagSafe-compatible case. Glad to hear you’re enjoying the battery life and quick top-ups!

    I gave this to my oldest son as a Christmas present. He really needed a portable charger that was compact and lightweight, and this was the perfect fit. It also provides charge for a decent amount of time and like that there are multiple outputs to charge multiple devices.
