    This is an amazing MagSafe portable on the go charger. I highly recommend it & have had numerous people ask where they can get one.

    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.

    Works just as listed. You can pop it right into the phone or put a item on it and it has nice 4 dots of lights for the indicator on the bottom and a status light and the charge works well for a full day out. Thin profile is great and great for the price

    I bought this charger to go along with my daughter’s brand new iPhone 17 Pro max. It’s completely compatible and perfect sized for the phone. It also charges really quickly.

    The unit works ok. It does charge devices. However the output of the USB-C connection is supposed to be 5 - 10 Volts. I recorded an output range of 1.8 - 2.2 Volts. Well below manufacturer range. Because of the low voltage the unit was unable to power my device and will need to be returned.

      Hi ContractorDad,

      I’m sorry the power bank didn’t meet expectations and that you ended up needing to return it. Based on your experience, it’s clear the unit wasn’t performing as it should, and I understand how frustrating that can be. We’ll be sharing your feedback with our internal team for review so we can work on improving future products.

      Hi Ethan,
      Sorry to hear about the heat and slow charging. Wireless charging can generate some warmth, but if it becomes extremely hot, please stop using the device and contact our support team for assistance or replacement:

      Hi jerrydon6,
      Thanks for sharing your experience. Wireless magnetic charging can feel slower than wired charging, and some heat is normal during high-power transfer. However, if the heat seems excessive or unsafe, please stop using the device and contact our support team for assistance:

    Had to return it three times. One not working at all, another one, the USB-C charging cable included is too tight to the point that it damages the internal connector of the product (do not use the one provided, other quality cables work just fine). The third time, the product made a humming sound as well as a sparkling one.

    We bought this for our daughter as a backup after her phone died at a concert. We have the larger version which is a little bulkier. This version is very slim and light. You barely notice it in any pocket.

    I bought a wireless power bank from Best Buy, and it works perfectly with my iPhone 15 — very smooth and convenient to use. The staff were also very friendly and helpful. Great shopping experience!
