    I loved my energizer power bank, it’s really handy and I can carry anywhere, and it’s really affordable price. Took for awhile to charge back I used my ipad, iPhone and my Apple Watch to charge and still halfway full. I’m excited to take my trip soon and I have this.

    Great for our beach trip last month—and as a backup in the car! My phone started having issues, and the battery life on my husband’s phone was low…We needed to navigate to reach our resort, so it was a little tricky. The first thing I did was get the Geek Squad to dry out my phone (the connecting point had somehow gotten damp). Then, I asked about battery packs. The charger worked perfectly on the beach since it dies fast without WiFi! It charged my phone quickly and still had a lot of battery power left! Charging the battery pack once at in our unit lasted for more than 3 days!

    I've been meaning to get a portable battery pack for a while, and on a whim, I went into BestBuy right next to my mothers docs office just for a cable and walked out with this Energizer battery pack. I loved how they emphasized everything was better for android. 10/10 will buy again.

    This is an excellent product! I use it to keep my phone, iPad and MacBook charged when I’m not around an outlet. This product allows you to charge via usb-c or traditional usb, which is very convenient.

    It’s a very good device, it charges my iPhone 15 pro max like 3 times from 0-100 or 4 from 20-80. It charges fast. I’m really liking this product, specially for when I’m flying or going to disney parks. It’s not that heavy.

    The wireless charger worked well, and so did the external USB ports for charging the phone. I really liked the display to tell you how much charge is left and there is a green LED to tell you it is actually charging the phone. You need to turn it on to actually charge, at first I thought that was a bad idea but then soon figured out that it actually held a charge when you are not using it. I think you only lose about 1% a day if you are not charging the phone. I was also very impressed on how quickly it charged back up again (I was using a 25W adapter). The only negative I have is if I ran the phone all the way down, I don't think you would get more than two top offs before you need to recharge the bank. Would be good for one phone (I run a Samsung S21) or maybe two phones if you charge it every night before use. I probably would have given it 4.5 stars if I had the option, but I don't think it deserved 4 stars so 5 stars it is.

    The charger is a little big and heavy, but it charges the phone very quickly and doesn't use much of the charger's battery. One charge from the charger, you can charge the iPhone at least 3 times

    Great power source. Due to my job I’m always on the road. This battery last more than few days without charging. The size could be just a bit smaller but other than that it’s great!

    I really enjoy this product because it has a numerical indicator for how much battery is left. My other one has the bar indicator. The size is a bit large but having wireless charging is super convienient.

    The charger works amazingly well. The charger holds a charge for several days. I've only had to charge it once since buying it. It is great to be able to charge up to 3 devices at the same time. I even use it for my Oculus, which I bought from Best Buy, by keeping it in my pocket, while I use it, to keep it charged. It really is great.

    Bought 2 of these for a trip to Europe. It is heavy, but worked out well as it does speed charge. On a new iphone I could get about 3-4 charges out of it before it would die. Better quality than any other I have bought in the past, especially for the price.
