Customer Ratings & Reviews

I've been really impressed with the Energizer Ultimate Lithium 20,000 mAh Power Bank! The large capacity means I can charge my phone, tablet, and earbuds multiple times, and the LCD display is super helpful for tracking battery life. The Qi wireless charging feature (up to 15W) is great for quick, cable-free top-ups, and the 20W USB-C Power Delivery port is perfect for fast-charging my iPhone to 50% in just 30 minutes. Plus, I can charge up to three devices at once with the various outputs—super convenient! With built-in safety features and a great price, this power bank is a fantastic value for anyone looking to keep their devices powered up on the go. Highly recommended!

I’m very happy with his charger. It has two different ports for different size cords to be plugged in. It stays charged even when you don’t have it plugged in. It charges your phone pretty quickly and it has more charging power than smaller devices. Very good for trips because it lasts for a while.

The Energizer Ultimate Wireless Charger with LCD Display is a handy little gadget, weighing just under a pound, so it’s easy to toss in your bag and carry around. The LCD screen is super clear and shows the exact percentage of battery left, which is awesome—no more guessing if you’ve got enough juice. Charging is a breeze too; just pop your device on, and it starts charging wirelessly. Overall, it’s a practical, straightforward charger that’s perfect for keeping your devices powered up without any hassle.

Excellent power bank with strong performance. The 20,000 mAh capacity lasts a long time and easily charges multiple devices. Fast charging with USB-C PD works great, and the wireless charging is very convenient. The LCD display is helpful to check the battery level. Solid quality and reliable product. Very happy with this purchase from Best Buy.

It's a little bulky, but it does it job. I bought it to charge my phone for longer rides. It comes with usb, usb-c, and micro usb input ports. A little display screen showing 100 to know it's fully charged. A power button to check the display screen. Charging time is okay.

Excellent capacity and features. I like the iq wireless charging for up to 20W. My favorite feature is the 1.4A charge mode which lets you minimize charging rate to a minimal current so it gives me peace of mind when charging tiny devices like ear phones and smart watches. At 27,000 mWh it's 7 times larger than my phone's battery and just as large as my 12" tablet's battery. Without a 60W PD charger it takes 11hrs to charge instead of 3hrs.

PROS: Hold a charge very great and the feature of having it wireless charge is always great as well. Doesn't take long to charge up the device for trips. Usually about 2 hours. CONS: Have to make sure you have a wireless capable case on so the wireless aspect works. The wireless setting only charges at a 15watt which yes is pretty slow so if you're low on charge just plug it up.

Hard to carry around because it is really heavy and somewhat large but it definitely works. I charged 3 devices at one without a problem. Well...there was one issue. I have an Otterbox case on my Google Pixel 9 Pro and the wifi charging had a bit of a hard time staying connected. You have to keep an eye on it because it'll look like it's charging but then it'll stop. Not the fault of the battery though. Just a note to be aware that if you have a decent case it may have trouble.

This is a very convenient and needed purchase. Where I really don’t need to worry about “Do I have my cellphone charger with me”! Plop this wireless charger in my purse and there you have a quick and simple solution to charging up any my electronics items. It’s Great!! I wish I got one sooner.

Plenty of capacity, decent charging speed and built in wireless charging so I don’t need a cable for my phone, it is thick but that should be expected with the capacity

The QE20010PQ has a lot of power! I was able to charge multiple devices while on the go traveling around the world where sometimes my options were limited. The only negative I had was I had to put my iPhone at an angle to use the wireless charging. It couldn't sit flat. That being said, with it's large capacity I was never without power. I used it with my phone, tablet and laptop. This battery also charges up quickly so it is always ready.

Good quality power bank, especially for the price, which I got on a deal during black friday. It’s also nice to have the LCD screen showing battery level. But it is quite weighty though, and also it took me a while to find the spot for qi charging because the magnet is pretty much nonexistent. But overall, it’s a pretty solid product considering it’s capacity and that it does what it’s intended to do.

It is a very practical charger. It is very functional if the USB-C input is damaged. It can be taken anywhere without the need to connect a cable.

Easy to charge and easy to use. Fast charging even when charging wireless. For the price, it is worth it. I recommend this product to anyone that could use a back up power source

[Employee of bestbuy] Fantastic battery charger. Makes a world of a difference when it tells you the battery charge on it and its super simple to use.

This thing is amazing and come with the 3ft cable which I thought I would buy extra but Thanks it’s inside the box

Worked great until it didn't. Exactly as I said. All of sudden it's giving me an error code and doesn't work.

Pros - 20,000 mah (that’s a lot by the way) Can charge multiple devices simultaneously Wireless charging compatible Good price Cons Don’t try and put it in your pocket it’s far too heavy, use a bookbag, otherwise it’s fine.

Got it for a trip I took a couple of weeks ago where i knew i was going to have long days of lots of walking and minimal access to places to charge my phone. It was a great help to keep me safely away from the dreaded final 20% remaining power color change in the battery icon on my phone. Also really liked the wireless charging during moments I was able to sit down. Lasted me the whole weekend without needing to recharge the bank itself.

This sure is a handy little gadget to have around, it charges easily with a type c cable, and it holds the charge well. As with any battery type device, especially a lithium battery, it gets warm when you charge it so pay attention to what you set it upon when you charge it. It has a bit of weight so it's not something you will carry in your pocket but if you carry a briefcase, purse, or backpack just carry it in that. When you are not around a power source this will be a welcomed device.
