The Energizer MAX 30,000mAh 30W PD 3.0 USB-C 3-port Power Bank is a great portable and affordable power solution when extra power capacity and fast phone charging is important. With a handy wrist strap attached and weighing in at only 1.3 lbs, this power bank is the perfect companion when away from a charging spots, as it should give you up to 108 hours of additional phone life, and up to 24 hours charging for large tablets. On my Google Pixel phone, it supports Fast Charging, topping off a phone with 60% battery left in about an hour. It ships pre-charged, so you can use it right out-of-the box. Mine had a 73% charge when I opened it. The Energizer MAX has a large bright LCD display, which is easily readable even in full sunlight. The power bank includes a 3ft USB-C to USB-C charging cable. A surprise not listed in the specs is it includes a BRIGHT WHITE LED FLASHLIGHT activated & deactivated by pressing the power button for two seconds. REALLY COOL!!! The Energizer MAX has three ports, two USB-C PD In/Out, and one USB-A Smart Fast Charge port. The main USB-C port is rated 3A. Although the specs claim laptop charging, I found that my 2020-era 65W HP 14” laptop was flashing the charging icon when attached, however the power bank charged the laptop when powered off. I’m not sure if newer laptops with less power demands and newer Power Delivery specs would handle the 30W PD limitation. I would definitely recommend this product.

I bought this to replace an Anker block charger. Very happy with this purchase. I use it mostly to charge my phone overnight when traveling. My old charger would give about 2.5 charges. I've used this four nights and I still have 60+% left on this charger. A tremendous upgrade. In addition, it gave me about a 30% charge in about 20 minutes. The flashlight is a nice addition and gives just enough light to find your way. My only drawback is that it takes a long time to charge to full, even with a fast charge adapter. When it got up to 97%, it seemed to stay there for a couple of hours. When I checked later that evening, it was at 100%. If you plug it in in the morning, should be no issues with 100% by evening

I love my new Energizer 30,000 mAh 30W Power Pack. It has plenty of stored energy to charge my Galaxy Z Fold5 (or anything else) many, many times over (at least 8X) before having to recharge the Power Pack itself. I really like the built-in flashlight and the super handy strong leather carrying strap. The Power Pack fits in my jeans pocket, and I slip my belt securely through the carrying strap. I can also use the strap to securely attach it to my bike. Very handy feature. I highly recommend this Energizer Power Pack. My highest recommendation. 5-Stars.

First of all the item when opened came with scratches like it had been used, i read the reviews from the past and i thought it was an isolated incident so didn't pay much attention to it. However, when i opened it did come scratched, I have ordered a power bank from a different brand, anker, and that one came like it was suppose to no scratches brand new, so i don't know if i got a returned item, or is this how they all are made. Well despite this the item does work, it came with 0% battery and it does takes like half a day to charge. While charging it didnt overheat, it does charge fast. I would recommend this product because it works for what its suppose to, but who ever is packaging they should be more careful or put a protective film to not scratch the screen.

I really like the amount of charges I can get off of this battery pack! My phone connects to a depth finder for fishing in my kayak so it drains the battery fairly quickly. This battery pack last long enough I can go for a 2 day fishing trip and not need to recharge the battery for continued use. Plus having the USB and USB-C ports I can charge my phone and the depth finder at the end of the day if I need to. Also has a flashlight on the battery pack to use at night while camping!

This product is very comfortable and high quality. The battery life is excellent; you can charge several phones at once, and I've even charged other devices with it. I highly recommend it. Thank you, and don't hesitate to get it.

Took awhile to charge up bit after it got to 100% it been excellent charging up my device at superspeeds,charged my iphone 17 promax and my wifes S25ultra only went back to 91% I’ll recommend this as an excellent buy wish i had this when i went to Jamaica the other dy where there is no power in country area becuse of the hurricane

Shipping was quick and came with a 87% charge out if the box. Used on and off for a full day and only used 5%. Quick charging. The one downfall is that its pretty heavy, so not something I’d throw in my purse. The 3 ports are useful.

This charger really packs a punch! While it is a lil heavier then what I expected, the charging power and speed is worth the weight. It is perfect for easy charging multiple devices at once.

You get what you ask for along or power . It’s a heavy battery but it never fails when it comes to power. The nice leather strap makes portability really easy especially when carrying groceries.

So far so good works amazing and does charge my s24 ultra pretty quickly. Definitely holds multiple charges and worth it for the price.

Great power bank! A lot of juice for any gadget you might need to charge!

Over all security if electricity goes out. Haven't used on 3 device's so cant say. But for the price n easy to use take with carrying strap. It's nice

Keep it in the car glovebox so don’t drain the car battery when stationary and need to charge the phone.

Solid battery pack. Used it over the weekend and lasted all day to recharge phone at air show event. It's a bit bulky if your okay with it. yeah about 1.5lbs. you'll notice the weight in the backpack.

Keep on going, and going, and going!!! Great buy! Thanks a lot bestbuy!!

I’ll recommend this product to anyone. I am really enjoying it

I opened this Christmas morning. It was the exact one I wanted, so I ripped the box open and disposed of the packaging. When I went to plug it in a few minutes later, I noticed the display was scuffed up and grit stuck in between the cracks. It had clearly been well used. I did not order open box item. I’ll use the charger myself and hope for the best. I did get a good deal on it.

I’m very happy with this purchase. The Energizer Ultimate Lithium 30,000 mAh power bank is powerful, reliable, and well built. It charges my laptop, phone, and other devices quickly, and the 30W Power Delivery makes a noticeable difference compared to standard power banks. The LCD display is a great feature—it clearly shows the remaining battery percentage, which is much more useful than simple indicator lights. The battery lasts a long time, even with multiple devices connected, and the three ports make it very convenient for travel or long days away from an outlet. It’s a bit larger and heavier than smaller power banks, but that’s expected given the high capacity. Overall, it’s a solid, dependable product, and I would definitely recommend it to anyone who needs serious portable power for work, travel, or emergencies.

In January 2025, I got the Energizer Ultimate Lithium 30,000 mAh power bank, and it rapidly became my most important travel buddy. I travel a lot to other countries, and this power bank has helped me a lot on long flights and layovers. Charging using USB-C is really rapid; it immediately charges my phone from low battery to full. The LCD screen is another thing I like because it plainly shows how much charge is remaining. The 30,000 mAh capacity is great because I can charge my phone several times without having to go for an outlet. I can charge more than one gadget at once or even help another traveler with three ports. The 30W Power Delivery is a great feature that helps keep everything running smoothly. The only bad thing about it is that it's heavy. I can feel it in my backpack on lengthy journeys. I'd rather carry the extra weight than take the chance of running out of power, though. In general, I would recommend this portable charger to anyone who travels a lot because it is strong, dependable, and well-made.
