I got this so i could score baseball games on my ipad 10th gen and stream the game at the same time on my phone 13 pro max. The games are doubleheaders that take up to 6 hours. This charger would easily keep both devices fully charged and would have at least 50percent left. It easily charges both devices simultaneously. Also as soon as you plug your device in it charges. No button to push. I absolutely love this charger.

I recently purchased a wireless portable charger from Best Buy, and I have been extremely happy with my purchase. The charger is small and lightweight, making it easy to take with me wherever I go. It has a high capacity battery, so it can charge my phone multiple times before needing to be recharged itself. I also love that it has a built-in LED light, which is helpful for finding things in my bag or for using as a flashlight in a pinch. Overall, I am very satisfied with the performance of this charger and would highly recommend it to others.

I didn't think that this charger would be as good as it is for charging long term. However i am throughly impressed with it ability to hold a charge once full. I am in Law Enforcement and on special occasions like parades and city planned events you most often cannot leave your post to charge up your phone, laptop or ear pods. I was able to do both as well as a few other Officers who had phones. Its an extremely reliable charger that i would buy again if needed....

This is the perfect on-the-go power bank. With its QI wireless charging abilites, I never have to worry if I don’t have a charger with me. Just bring it and youre good. Of course you have to charge the device itself with a micro usb, but the charge lasts quite a long time. I have charged my iPhone 13 Pro Max multiple times and its not even close to being half way depleted. Great item, would highly recommend.

Great battery pack that works very well. The wireless charging is fast. The only issue I have had is it say per-charged and I found it was only charged to just over half. Three light were on but when I plugged in my phone to charge it dropped to half right away. So take it out and charge it up before you need to use it. This thing is also a but larger and heaver that I thought it would be. But the build is very nice

I bought the Energizer 20,000mAh Wireless Portable Charger before my families big trip to Europe. Tested the product to ensure that it will suffice what we need it for. Very impress that it can charge my iPad Pro, MacBook Pro and wirelessly charge my phone all at the same time. The is the perfect companion to keep your tech equipment charged. Its slightly heavier than expected but overall, I highly recommend.

The wireless pad seems a bit spotty with a case

Amazing charger overall and has good capacity. It feels tough and fairly premium: it reflects the price tag in regards to build quality. The one point of contention would be that with a big case on your phone, the wireless pad can be a bit spotty. An annoyance to remove the case certainly.

Great product, overall I have been using this for travel and on the go charging when I forget to charge my phone at night.
Pros: If I forget to bring my cable, I’m still able to charge through the wireless charging feature.
Minor downside is the weight of this power bank. Expected it to be lighter than it looks.

This was a holiday gift but, the person said he loves it and it holds the charge like it's meant to do and has multiple ports for other electronics. Not light weight but, will work great for all adventures this coming summer for outdoor activities away from electricity. He recommends.

The Energizer wireless battery pack was something I had been trying to get for a few months now, but it wasn’t in stock. So I finally got it a few weeks ago, it’s something good to have if you are someone that’s always on the go and need something to charge your tablets and smartphones and you don’t always access to a wall outlet to charge your electronic devices. This battery pack is good to have.

It’s a little heavy but the battery pack works great. Goes with me when the family goes fishing at the lake and when I’m running around town. Love that you can charge more than one phone at a time

I really love this product, it has 3.0 USB port, a USB-C port, and it has the capacity to wirelessly charge my iPhone, this last feature I wasn't aware of. I can just turn on the power bank and seat my iPhone on top and starts charging... plus it holds power for few days with normal usage. Great product!

Charger works great and really like that its slim, can fit in my pocket with my phone not like other chargers that are too thick. Wireless charging works great, but only if you have it sitting on a table or something flat, it doesnt work well vertical, because the phone may move off it and stops the charge.

Great! Bigger then expected, get the slimmer version if you wanna carry it daily to work and such in your pocket, Otherwise if you have a backpack it would be fine in there. Holds a charge really good! I didn't use it a for a month at least and it still had a good charge.

The 10,000mAh version of this power bank is much more travel friendly. It seems to charge fast enough, but feels like a brick.

Portable battery that works fairly well. The power button is sometimes not a responsive to turn on as I would prefer. Holds a good charge for days on end. Wireless charging pretty quick.

We havent bought one of these in awhile. We were able to charge our phones like 4-5 times fully before the blocl needed a recharge. It charged really quicky. If inremember correctly it was a little more than i wanted to spend but worth the money if you travel a lot.
