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.

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

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.

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!

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.

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.

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

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.

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

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.

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

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

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.

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.

I purchased the Energizer Ultimate Lithium 30,000 mAh Battery Charger because there has been one too many outages in my area. I like that it has an exact percentage meter that clearly tells you the amount of charge that is left in the battery charger. It has 3 ports so you can charge 3 devices at one time. This battery charger also has a carry strap for on the go. I recommend this battery charger because you can also charge devices on the go. Cell phones need to be charged all the time and imagine getting stuck some place and you can't make a call. Get yourself a battery charger!

Decent power bank. It is heavy and bulky. I like the sturdy hand strap. Charged my cell phone 4 times from 0%. The charging speed is good. It took 20-30% of the battery each time I charged my phone. It used less battery when the phone was off while charging. I like the flashlight. It's useful. It took 5- 6 hrs to recharge. For comparison, I have a similar, more expensive Anker power bank that takes 8 hrs to recharge. I only get 3 phone charges from that one. The only issue is the size. Otherwise it's a good purchase.

this is honestly a great investment. Ive bought other portable chargers like anker and they do not last. This is a great battery. Lasts A LONG LONG TIME, very durable & charges multiple devices. 10/10 recommend
