    Solid Product

    Good - very high capacity -feels quite durable as far as the casing. Definitely fits with it being a name brand product like energizer - wireless charging is quite quick -wired charging is also quick via the usb c and the usb a Cons -heavy although for a 20,000 mah capacity that is expected. I think the wireless charging pad does add a bit of bulk compared to other chargers - a bit pricey compared to others at this capacity however you are getting a name brand product that will likely last a very long time, wireless charging, and higher charging and output speeds -does not come with a transformer or USB c cord, this made it impossible to test the full speed abilities for charging the battery. Use Case For someone that wants a high capacity battery, values a name brand that will last a long time, wants wireless charging directly from the battery, and or has usb c and transformers that can fully utilize the quick charge features of this device

    Pros: 20,000 mAh for multiple full fast (QC/PD 3.0) charges for your devices. It has wireless charging as well. Has both usb-c/type a ports. Has a button on the side to check battery capacity. Dual charging inputs to recharge the battery bank faster Cons: Only capable of 3 simultaneous charging (2 wired, 1 wireless). Micro-usb port is only for input Wireless charging is a bit quirky to find the right spot. Quite thick for a power bank. Other thoughts: Instead of micro-usb, could have added another usb-c port to be utilized for both input/output for 3 wired charge simultaneously. For those that find a faulty defective power bank after a few uses (there will always be a few faulty ones in any electronics that get manufactured), there is a 1 year manufacturer warranty.

    I’ve bought many portable chargers, a lot of them degrade over time and within a year there unusable. I’ve had this one for about 2 years already and it does not look like its gonna die out on me anytime soon.

    This is a workhorse battery. It is a bit heavy but I wanted a charger that I could just set my phone on when not using to keep my phone full charged. Perfect. Has plenty of juice to charge my phone several times.

    Energizer 20,000 mAh Qi Wireless Charger

    It takes a while for this to charge, but it also has quite a large capacity. I can completely charge my iPad twice and still have enough to recharge my iPhone X once. Love the wireless charging feature that’s built right in. Placement of your phone for wireless charging is critical. There’s a very small “sweet spot”, and if your phone isn’t in just the right place it won’t charge. You can also charge one device with a cable and another one wirelessly simultaneously. Overall I think this was a good purchase and I would recommend.

    Charges but it is very heavy compared to my last one that I could just put in my back pocket and charge when I was at a concert. My other does not work with my new iPhone 13 Pro max. Got it because it was on sale!

    It's heavy but given that it's 20k mAh that's expected. Wireless charging works fine but you need to press the power button once after you place the phone on it. People have complained about the charger not charging beyond 3 lights but mine got charged full in 2-3 hours.

    I love this Energizer Power Bank! Whether charging wirelessly of with the good selection of ports, this charger continues to do a great and speedy job. I love the size and weight, small enough to fit in my purse, but with enough heft to recognize it is still with me and not lost in the fray. Definitely recommend!

    Very worth it if you need something on the go to charge your phone with. My plug in charger has been finicky and the wireless charging works the best for my phone so this is perfect for that and hardly needs to be recharged for quite awhile. Helps out when in a tough spot where battery levels are low and you need a good boost to get you by!

    Pro: works for Apple & Android phones Quickly charges Power bank has enough power to charge multiple phones once power bank is fully charged. Last long time, charged multiple phones over a period of time. Con: inductive charging does not work with my phone case on. I had to take my case off and move my phone around until it finally connected to charge. When my phone was on the power bank charging if I moved it slightly it would not charge. Also Would not charge my Air Pods or My Apple Watch.

    Definetely worth the price, while you might think its slightly expensive this amount of power would last for around 1 day - 2 days worth of charges depending how often you charge your phone and a nice thing is that it comes with the wireless capability which it might not look super nice, its nice thing to have to give it a better aesthetic.

    The charging ports can be slow and are not as fast as some of the other portable chargers I have tried (such as Anker). The qi wireless charging on top works pretty good though, but it drains battery real fast that way. I find myself charging it up after every use. It also weighs like a brick and is defintely not something you should carry in your pocket for long periods of time. Get it on sale, otherwise it's overpriced and not as good as some of the other brands out there.
