    It is lightweight, convenient and very easy to use. However, it is advertised as a rapid charger, but it is not consistent with the speed at which it charges my phone.

      Hi Prep,
      Sorry the size and magnetic attachment didn’t feel right for you. This model uses a gentler magnetic design to avoid excessive force on the phone, so the grip can feel lighter—especially with thicker or non‑MagSafe cases.

    Phenomenal, just not built for Samsung

    As a portable charger, this thing is great, the functionality from a USB-C output along with qi2 wireless gives it some excellent versatility, plus one full charge can bring my phone ans ear buds back from 30% to full twice. Just keep in mind that while its has magneticd wireless capabilities the rectangular shape doesnt sit flush with the camera on Samsung. Still very usefull but I would say you only get the full capabilities with a Iphone or Pixel.

      Hi JonathanM,
      Sorry the magnet feels weaker than expected. Case thickness or non‑MagSafe cases can reduce magnetic grip, causing the power bank to shift. Good to hear charging performance has still been solid.

    I’m sure it works amazing like the smaller 5,000 one I had, unfortunately the one I got charged quick with a cord but when used wirelessly it wouldn’t charge much at all. I exchanged it for the smaller/slimer model again! It’s a little bulky but would still recommend both the 5,000mAh && this 10,000mAh model to anyone ! They charge extremely fast with the cord, and if you get the good one fast wirelessly ! Great for anyone in the go and needing a quick charge! And again you can’t beat the price for a wireless charging option!

      Hi DanielD,
      Thanks for sharing your experience! We’re glad you enjoyed the fast wired charging and overall performance. Wireless charging can sometimes vary due to alignment or phone case thickness, so your feedback is very helpful. Great to hear you found the slimmer model a better fit—both options are solid choices for on-the-go power!

    Great portable charger. I used my BestBuy Membership to get a great discount on it, but gratefully surprise me the good quality and rendimiento. I replaced many other powerbanks bought in a famous online retailer, many of them recalled for many issues.

    It can charge my phone 1.5 times (iphone 13). The magnet is not strong. I have an Anker one and that one "sticks" better.

      Hi RicardoA,
      Thanks for sharing your experience! Charging your iPhone 13 about 1.5 times is expected for a 10,000mAh power bank due to energy loss during wireless charging. For the magnet strength, it can vary by case thickness and design—using a MagSafe-compatible case or no case usually improves the hold.

    I found it good MagSafe charging option for IPhones, while traveling you don’t need to worry about your phone’s battery life, does a pretty good work at this cost, little issue what I felt was a bit slow charging and a little heating issue which again is not a bothersome thing.

    Good christmas gift, still havent opened it or tried it but i have the same one and i like mine. Although, the wireless charging is almost useless in most prtable charging scenarios, it's still nice when you can use it. I use mine as a wireless charger at home mostly.

    The magnacharge feature generates a significant amount of heat and is a slow charge of iPhone. Using a cable to charge an iPhone is a little faster. It’s ok for the price.

      Hi DanB,
      Thanks for sharing your feedback. Wireless MagSafe charging can generate some heat and is generally slower than wired charging due to power transfer limitations. For faster and cooler charging, we recommend using the USB-C cable with a 20W adapter. If you have any concerns about excessive heat or performance, please reach out to our support team:

    Product was on sale, quality is alright, but I wouldn’t have bought it if it was full price, magnets get jostled around if dropped, but it’s easy to remove the back panel (whether that was intended or not) and rearrange the internals.

    This is a great inexpensive charger. It can attach to the back of your phone magneticallywhile charging. It’s slim enough to still fit in a pocket or bag. It's ood for 2 charges at least on my s23 ultra and stays charged for quite awhile when not in use (days at least). It has a durable metal design, and can charge multiple devices at once. Really good bang for your buck
