    As a student, my days can get pretty long, and I'm not always able to find an outlet when I need one. That's why this battery comes in handy because I can quickly charge my phone back up when I need to no matter where I am on campus. The Qi wireless charging is huge because I don't even need to think about bringing cords along with me. I just set my phone on the battery when I'm in class or in the caf and my phone charges quickly and easily. I just charge the battery up every night and drop it back in my backpack every morning and I'm good to go. The battery is small enough to even just carry in a coat pocket, and the display helps you to know how much battery is left. It's fantastic!

    I recently purchased this charger and it has quickly become my go-to charger for when I'm on the go. Most of the chargers I own are large, bulky, and a hassle to carry around in my pocket. However, this charger is the perfect size and fits easily in my pocket without weighing me down. What initially drew me to this charger was the fact that it is compact and lightweight, making it ideal for travel or everyday use. After trying out this charger, I was thoroughly impressed. It easily fits in my purse, without weighing me down, which is a major plus when on the move. Additionally, I loves the fact that it can simultaneously charge my phone and AirPods. Overall, I highly recommend this charger. It not only solves the problem of bulky chargers but also offers convenience with its ability to charge multiple devices simultaneously. If you're looking for a reliable and portable charger, this product is definitely worth considering.

    I love the variety of different inputs you can use to charge up the power bank, found it to be very useful when you only have a specific type of cord lying around. Though, it charges itself and your phone quickest if you use a USB-C power cord to do so. Another great feature is the mini-screen that tells you the exact amount of charge left in the bank; it helps you to know how much time you have before its dead. This is definitely the first power bank I've ever used that has a wireless charging feature, and although it's cool, I really can't see much use in it unless you completely forgot to bring a cord along with you.       How quickly this power bank is able to charge your phone up is very dependent on the cord that you use. Despite that it uses USB-B 3.0, I found that it will still charge your phone much more quickly if you use a USB-C. While streaming videos on my phone, It took roughly an hour and a half to charge from 0-100%, which is fairly fast considering that I was using it while it was charging. Along with this, that only used about 60% of the overall charge of the bank, meaning that this will last you plenty if your phone has poor battery health and you're just trying to get it through the day. It is less important, but I found that it took roughly 2 and a half hours to charge the bank itself up from 0-100% while using USB-C.       The only reason for my not giving this power bank 5 stars is that I felt it charged a bit slowly and drained itself a bit quickly for being 10000mAh. But if you're just looking for a solid power bank to charge your phone throughout the day, this power bank will definitely do the job! I would say 4.5 stars to be honest.

    Sleek and effective charger! I needed something the right size to have in my purse so I can charge my phone, air pods and gaming accessories. This powerful and small charger ensured my chargeable devices were powered up while I was away on a long weekend. I have used larger sized chargers before and they are not as convenient when traveling or spending a day shopping. I like the light weight, sleek design and quick charging features! Love it!

    I bought these right before my trip to Cancun and I can say, thank god I bought these. My phone would die from me taking pictures of my trip and the wireless charging helped me a lot. It was quick and I was able to get at least 50% back in like 45 minutes or so. It's also very light, so I barely felt it in my backpack during the whole trip.

    This is a great power bank. Love the wireless charging and the digital percentage display. I no longer have to guess how much juice I have left. Much improved over my last portable power bank. The packaging is simple and has minimal waste. Would recommend to anyone looking for a good power bank

    Great Charger, Super Portable, and convenient in a pinch. The 10,000 mAH capacity was able to charge my Google Pixel 8 Pro twice on a single charge of the power bank. The inclusion of fast wireless charging was nice for cases when I did have a usb cable one me. My favorite use case for this is actually keeping it in my pocket and using it to provide extra life to my VR headset during long play throughs, the battery bank is light enough that I hardly noticed it. The one downside I had is charing it, when plugged up to my fast charging wall brick over USB C it took about 5hr to go from zero to full charge all though that could have been user error.

    The charge is sufficient to charge two of my devices, my Pixel phone and my son's Fire Tablet. We recently went on a trip and although I had to charge fully overnight it was great to charge my phone while being able to take pictures of our trip. Doesn't come with a charge cord.

    I bought an energizer and traveled next day to Cameroon with , upon arrival I noticed it has bulged in it’s packet. Was so scared and wondering what to do with. I can’t even tell someone the article is from the US. Wondering weather to throw it or let consumer control know. It may not be a safe idea to transport it back. I have never had such an issue with Best Buy since 15yrs shopping there

    It’s a good power bank that is light weight and roughly the same size as my phone. I like that it has multiple ports for charging various tech and that it displays the amount of battery life left which is much better than the chargers that just show dots. Although it can sometimes be difficult use a Qi through an Otterbox case, this works quite well. That said, I will be using a chord with this since it’s a little slick and it isn’t magnetic.
