Customer Ratings & Reviews

We grabbed this brick while on vacation, and it was a lifesaver! Being able to charge both of our devices simultaneously was crucial, and this handled that perfectly. It's a bit bulky, but we don't really care about that as long as things are charging.

This thing is essential for trips. It came pre-charged at 80%. I charged it which took about 25-30 min to be at Full. It charged my phone about 3 times over and it still had around 80%. It’s built like block so it pretty durable but a lil heavy.

I used this so much I rarely ever use my outlets ( unless I'm charging this ) It can charge both my tablet, watch and phone quite efficiently and it last forever! I've been looking for something like this for a while, so I'm really happy to have something that last.

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!

The best portable charger because it can charge my phone 3 times without needing charging itself. It's a bit heavy but I'm okay with the weight because of its power. I bought it on sale so the price was reasonable.

Charges faster then a wall outlet Charges all my different cell phones Charges my laptop and is very reliable especially if you travel or work on your phone

Great portable battery, charges my phone up pretty fast. I'm thinking about buying another one.

Excellent product. I went on a trip to the philippines. It was a 23 hour flight. I was able to charge my phone.I'm not worried about my battery getting low when I arrived there.

Great. Very reliable. Easy to use. Long lasting battery life.

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

I've spent more money and have had less quality. This is well- built, the charges are amazing. I can carry this and use my phone for 2 days without visiting the plug. It lives up to its promises.

I purchased this charger on a whim, but I do not go anywhere without it. Orginally I brought this for my camera as I was recording a wedding for a client. I was impressed that throughout a constant use for about 7 hours straight I only drained about half of the battery. This is a life saver and a gem of an item, If your reading this to help you consider making this purchase. Then please but this. You also get two type c connectors and a usb.

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.*

Works great!, charges phone fast, light to carry and overall best bang for your buck

It charges more than one thing at a time, and charges them both fast

Super fast charging with a pretty substantial battery life

Excellent charger!!! The Battery life on this portable is well worth the price! I Highly recommend if you are constantly traveling to get the post charge!

I like this! Fast charging and long lasting! It's working out great!!

Nice and portable three diferent outputs real fast to charge my phone en earphones and not expensive!!

okay so iv had this about almost 2 weeks and i liken it a lot it took me a bit to figure out like how the charging works, but it’s pretty simple. The battery for the charging last forever like I’m barely hitting 70% on it and it’s been like almost 2 weeks charging it takes about I wanna say four to get eight hours for a good battery hold i’m charged my iPad my phone more than like twice on it
