    Love this charger. You only need the cable to actually charge the charger. The magnets hold the charger on the back of the phone so you don’t have to deal with any wires. It has more than enough juice to charge your phone to 100%. Perfect for stocking stuffers too.

    I bought one and accidentally hit it against the wall and dropped it. The side that charges came open so i bought a second one thinking it would stop working. To my surprise it still works so I haven’t even open the new one.

      Hi Rockn,
      We’re sorry the magnetic hold felt too weak. This slim design prioritizes portability, so the magnet strength may not fully support movement, especially with heavier phones or cases. For better grip, consider using the power bank on a flat surface or pairing it with a MagSafe-compatible case. If you’d like assistance or a replacement, please visit:

    Wireless charging works well with Galaxy phone on table or in my pocket. Some power banks have inflated capacity ratings so I tested it: Rated 5V 6000 mAh, actually delivered 5V 35.1 Wh > 7000 mAh.

      Hi DavidK,
      That’s impressive testing! We’re glad to hear the wireless charging works well and that the actual delivered capacity exceeded expectations. Our ratings are based on nominal voltage, so your measured watt-hours confirm strong real-world performance. Thanks for sharing your experience—it’s great to know the product is meeting and even surpassing your needs.

    Fairly compact for a 10,000mAh battery pack. Strong magnet that stays on my phone well. Gets a little warm sometimes while charging but never too bad.
