Customer Ratings & Reviews

The portable charger I recently tried has been a game-changer for my on-the-go lifestyle. With a sleek design and lightweight build, it fits easily in my bag. The 20,000mAh capacity provides multiple charges for my devices, ensuring I never run out of battery during long days. The dual USB ports allow me to charge two devices simultaneously, which is incredibly convenient. It also features fast charging technology, reducing downtime significantly. Overall, this portable charger is reliable, efficient, and a must-have for anyone needing extra power while traveling or out and about!

I’ve been using the Energizer Max 20000mAh Power Bank for a few weeks now, and it’s been an absolute lifesaver! It charges my phone, tablet, and even my wireless earbuds at the same time with no problem. The 15W USB-C output is fast enough to get my phone from 20% to 80% in less than an hour. The battery capacity is amazing — I can easily get 4–5 full phone charges before needing to recharge the power bank itself. It’s a bit on the heavier side (as expected for 20,000mAh), but still very compact and easy to carry in my backpack. The design feels solid, premium, and durable, with clear LED indicators that make it easy to see the remaining charge. I also like that it supports both USB-A and USB-C ports, which makes it super versatile. Overall, this Energizer power bank is powerful, reliable, and worth every penny. Perfect for travel, work, or emergencies. Definitely recommend it to anyone who needs real portable power!

We took this with us on a two week trip through London and Paris, and while it takes a few hours to fully charge up to full because of it's sheer capacity, it will in turn last for such a long time, which is highly necessary when traveling abroad and power sources aren't always going to be guaranteed where you're going to. I kept this in my front-body bag and it worked like a dream whenever my phone starting getting tapped out from using maps/GPS a lot. The other factor to keep in mind is that it is decently heavy, though if you have a small enough bag and you're not carrying too much else around with you it's not that big of a deal to me at least, but I have seen other reviews that also mentioned that. To me the higher capacity of the battery outweighs the minor inconvenience of *carrying something a little bit heavier than your typical tablet-sized phone.*

I’m very happy with this power bank. The 20,000mAh capacity easily lasts multiple charges, and the LCD screen is super helpful for seeing the exact battery level. It charges my phone quickly and having multiple ports makes it convenient to charge more than one device at the same time. It feels solid and well-made, and it’s been great for travel and everyday use. Definitely a reliable and high-quality power bank.

I bought a couple of these for a family trip, and they are workhorses that did what they were supposed to do. This battery has hours of capacity and is very reasonably priced. I purchased it for the value and was not disappointed. Be aware that these are bulky and kinda heavy, but you can charge a phone several times (3 or 4?) if this thing is fully charged. I think it's good.

Thie portable charger seems to have the rated capacity (unlike some others) and charges my devices quickly with a couple of port options (USB-A and USB-C). Even when cold it seems to work great. My only complaint would be the weight of this thing. It feels like a brick. It is great for the car, but I have another 20k mAh charger that is noticeably lighter that I carry in my backpack. To be fair, the lighter charger doesn't seem to have the same capacity this one does, but the weight does make a difference for me.

I did not know it would be bigger and heavy than a other chargers, But it works well.

I absolutely love my Energizer MAX 20,000mAh power bank! With its LCD screen, I always know exactly how much juice is left, and it charges my Samsung smartwatch and phone multiple times on a single charge. The three ports are perfect for powering all my gadgets at once—fast, reliable 15W output keeps everything running smoothly during long days out. Super sturdy build too.

Amazing! It charges my devices quickly and the battery lasts a long time. It is a bit on the heavier side, but worth it. It tells you how much charge it has and turns off on its own when your phone is not plugged.

Works well. Fits in my pocket abd i can get multiple charges on my phone from this. Would recommend

I love that I can charge multiple devices at once. The charge for the battery lasts me a long while, but I may not use it as much as the average person. The size is a little bigger than I would like but it still fits nicely in my small backpack.

I recently bought this power bank, and it has been an absolute game-changer for my travels and daily use. It charges my phone 2–3 times on a single charge and does so quickly. The compact size makes it easy to carry in my bag or pocket, and it feels sturdy and well-built. I also love the LED indicators that show the battery level. It’s great for road trips, flights, or just getting through a long workday without hunting for an outlet. Definitely a must-have for anyone who relies heavily on their phone.

Its great! obviously easy to use im glad it has a screen i got one on amazon and it had no screen and i didnt realize it when purchased and had to return it. glad i got this one holds its charge for a long time. not to heavy which is surprising

I have purchased so many charger banks for trips and things that literally work for a day or dont work at all. I came across this one and decided to give it a try as the reviews looked promising. When i went in store to pick it up, the sales associate said its the only one he will use and told me how he uses it. I have had time to use it now and it has been great! You can even charge multiple devices with it at the same time. We charged up 3 iphones one day and it still had lots of hours left.

This external battery is easy to use, holds a charge well, and charges my phone and laptop quickly when I need a boost away from a plug. Very good product

I bought this for myself for Pokémon GO Fest, and it crushed it. I was out in the sun all day, screen on full brightness, GPS and data running, and this charger never let my phone die. In fact, I still had power left after the event. It’s a bit heavier than smaller packs (as expected), but the battery life is totally worth it. Charges fast, lasts forever, and now it lives in my bag full-time. Highly recommended.

It charges my phone multiple times with one charge and I can also charge 3 devices at one time. Little heavy but it’s built to last for sure

A little heavy, great capacity, all ports functional, simple to use.

This Energizer MAX 20,000mAh Power Bank has been an excellent addition to my everyday carry. The battery capacity provides multiple charges for my smartphone and other devices, making it ideal for travel, work, emergencies, and long days away from an outlet. The LCD screen clearly displays the remaining battery percentage, eliminating any guesswork. Charging is fast, dependable, and consistent, while the compact design makes it easy to transport. The build quality feels durable and premium, and the multiple ports add flexibility for charging different devices. Energizer has delivered a high-quality, reliable product that performs exactly as advertised. I highly recommend this power bank to anyone looking for dependable portable power at a great value. Five stars and 100% recommended! ★★★★★

Since it was an Energizer, knew that it would be great. Didn't disappoint, for sure. Easy to use and instructions were well written. Definitely recommend this one.
