    Excellent product. Lightweight and portable. Charging fast. The casing feels cheap, not solid. I would give it a 5 stars if it feels solid.

    The magnet holds strong and it charges relatively quick especially on older iPhone models, namely iPhone 13. Product comes with its own USBC charging cable and it does charge up somewhat slow but its a tradeoff.

    Purchased two of these when on sale. Arrived quickly and they are great to have and carry around. Just attach to MagSafe phone cover and it provides power to the phone. Very Satisfied. Not large and bulky like some PowerBanks.

    I bought this for a trip coming up to Peru, where I’ll be gone for two weeks, and each day “out of the house” dawn to dusk. Wanted something to juice up my iPhone 16 Pro Max, and while it does a good job being an “extra battery”, it doesn’t exactly kill it in the power department. I think for smaller phones it might be okay, or with managing your expectations that you use it as an extra start to your battery life early in the day, where you use your phone with it attached, and then once it runs out it runs out. But expecting to charge it up back to full is gonna be tricky, so keep that in mind with your expectations.

      Hi JoshJ, thank you for sharing your experience. The 5,000mAh capacity is designed for portability and quick top-ups rather than full recharges for high-capacity devices like the iPhone 16 Pro Max. For extended trips or heavy usage, we recommend starting the day with the power bank attached, as you mentioned, or considering a higher-capacity model (10,000mAh or more) for full-day coverage. If you have any questions or need assistance selecting the right option, please visit https://support.energizerpowerpacks.com/.

    Got this on a black Friday deal, it works great with my phone, but does tend to warm the phone and gives an alert for slow charging. I’m not sure if that’s a concern or not.

    It works good. The only odd it’s that it heats up while u using the wireless feature. But using the wire it will be fine

    Excellent thin charger. It fully charges my iPhone 14 Pro and it’s MagSafe compatible so it attaches to the phone. The enclosure it’s metallic and it has a led indicator for the charge level. It’s very helpful on long days at work or whenever I forget to charge my phone overnight.

    Overall, its good only thing which I realize that backup is not much but at least a life saver where you do not have charging point.

    A slim design. I bought the 10,000 version and this version. Even though this one is only 5,000… i like it because if the size. In my opinion it is slightly less than half the thickness of the 10,000 version. It is at least half the thickness as you could imagine.

      Hi Richardw7,
      We’re glad you appreciate the slim design! The 5,000mAh version is indeed engineered for portability, making it ideal for snug pockets while still delivering reliable power. Great choice for on-the-go convenience!

    Slim portable charger that securely attached to the back of a phone using magsafe. Not the fastest or longest lasting, but does give extra battery capacity when needed.

    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
