    This is a great small battery pack that attaches to the back of your phone. Super easy to use and charges quickly. Like that it shows the battery life on the side so its readable while on the on the phone. Definitely recommend this battery.

    This is a great powerbank for IPhones and and Androids with a USB-C. The magnetic charger is nice for phones with thin cases, it also has a kickstand so you can use the magnetic charger while watching a show on your phone. The 2 cords connected to the powerbank make it nice so you can either charge 2 phones out you can plug one of he attached cords to a USB- C outlet to charge it’s own battery. No need to bring extra cords for the powerbank.

    Holy smokes this works a lot better than the ones I’ve ever had. Light weight, smaller than I expected which is great to carry around and yet very durable. Charges pretty fast and last long. Very satisfied and will definitely recommend for other family members. Also another plus is the stand behind the charger.

    I bought this Energizer magnetic power bank on Black Friday and I honestly don’t know how I lived without it. I’m no longer running around looking for cables or asking someone to charge my phone because I always have a fully charged backup with me. I love that it magnetically attaches to the back of my phone and starts charging immediately. The stand feature is a huge bonus, I can prop it up and watch videos or use my phone hands-free while it charges. The OLED display is super helpful, and the built-in USB-C cables mean I don’t need to carry anything extra. This is perfect for anyone whose charging port doesn’t work, and especially great for people who do DoorDash, delivery, rideshare, or are just constantly on the go. I’ve already sent the link to so many people. By far the best purchase I’ve made. Worth every penny.

    Great power pack but could be better.

    I don’t think this power pack supports a true Qi2 wireless charging as the description indicates. The battery settings on my iPhone 16 pro Max says it was using a slow charger. You can also see this on the Best Buy specification sheet as it clearly states “wireless charging standard Qi1” so there’s a contradiction between that and the main description on the product. A true Qi2 like the Anker MagGo 10K that I have does power my iPhone 16 pro max at a fast charge speed of 15 watts when I’m wireless charging. (The price tells it all). I did buy this power pack because I needed to charge my Apple Watch on the go. While it is slow to charge my Apple Watch wirelessly it’s understandable for the price. I like that it has 2 built in USB C cables for traveling. I have less clutter on me. The device does stay warm and not hot when charging my devices or when I’m charging the power pack so that’s a plus. This is also a pass-through power bank but again it is slow to power your device (wirelessly)and receive a charge simultaneously. If you have patience and not in a rush to charge your device wirelessly this product is good for you. For a faster charge you can use the built in usb c cables that the power pack contains which in my case was charging at 20 watts. Overall it’s a great power pack. I will be bringing in along the road when I travel.

      Hi Ace2000, thank you for your detailed feedback. You’re correct that Qi2 wireless charging delivers faster speeds (up to 15W), while this model uses Qi1 for wireless charging, which explains the slower rate. The built-in USB-C cables are the best option for faster charging at 20W, as you noted. We appreciate your insights on the Apple Watch feature and pass-through charging—it’s designed for convenience rather than speed.

    Let’s be honest - I’ve been through my fair share of portable chargers. But this one takes the cake! Innovative, sleek & can charge all of my devices at once. Super easy to take on the go. Would highly recommend!

    A little bulkier than I was hoping and the magnet is not that strong-tried attaching directly to my iPhone and also with my case (which has a magnet on it as well). The phone will move off the MagSafe charger easily so you have to make sure to hold the phone and the charger together to make sure it’s charging. Other than that it works as advertised. You do have to push the power on button to charge after you plug in or MagSafe charge. Minor inconvenience but something that baffled me for a few seconds when I first tried charging haha. It is really nice to not have to worry about bringing another cords to charge the charger itself or your phone. Boyfriend has a Samsung, wireless charging does not work with Samsung but it has the usb-c cords which work fine. We recently used this on our tried to universal/disney. It had enough juice to keep both of our phones charged all day while using the park apps.

    I got this because of some of the good reviews for it. I liked some of the features like the MagSafe, built in charging cables if needed, and the kickstand. I’ve been mostly disappointed by it. It’s very heavy and it’s extremely slow. It’s good at not letting your phone die when you need it, but it’s pretty clunky and again charges your phone slow. I think I saw in another review or possibly as a feature you can charge it with your phone on it but it stopped charging my phone at a certain point. And the actual battery reserve isn’t great. So I really doubt you could charge multiple phones at once, it would probably give enough power to keep phones from dying but it can fully charge one phone before running out of juice. So those extra features seem somewhat moot. I would look elsewhere at more reliable brands like Anker.

    No, I would not recommend this to a friend

      Hi SonM,
      We’re sorry the power bank didn’t meet your expectations. This model is designed for emergency backup rather than multiple full charges, so performance can feel limited compared to wired charging. The built-in cables and MagSafe are meant for convenience, but charging speed and capacity depend on device power requirements. We appreciate your feedback and will share it with our team for improvement.

    I got this at my wife's request for a magsafe power bank that we could toss in a bag or bring with for longer outings. Turns out this little device is a swiss army charger; It can recharge a phone and two other usb c items at the same time. It charges apple watches as well which is a nice bonus. For the price of one apple cord you can get this and do it all!

    Absolutely love this battery pack, not only does it tell you the output when charging your phone it has 2 cables attached to it which is very helpful. With a click of a button it displays how much battery is left in it. I charged two phones at once on my current trip and it is a quick charger. Fast and it hardly warms up when in use. Highly recommend buy it don’t think just buy it you won’t regret it.

    This portable charger has provided at least two full charges for my iPhone and still had about 20% life left. I did not give this item 5 stars even though it has a magnetic that connects to MagSafe cases, it does not charge via the MagSafe connection, only through the attached cords.
