Customer Ratings & Reviews

I took this charger on a 6 day trip and it held up to recharge my phone and tablet with no problem on a single full charge. The only issue i have is that charging it to 100% the first time seemed to take forever. It certainly took at least 12 hour going from about 80%to 100%. It is heavy and can get warm so be careful if youre carrying for long periods of time. Otherwise im satisfied with this purchase.

This charger has a lot of power! It takes a rather long time to charge but once it's full, it has the capability to charge my phone many times over, and my friends devices as well. It turns on as soon as it's hooked up to my phone cord and has an automatic shut off. I'd say it's a bit large and heavy, but considering how much it holds, it's probably worth it. There are lighter types but they don't have the power this one does. I'd recommend it for a long lasting fix when you can't get to an outlet.

I travel frequently and work remotely so this is crucial to keep up with my work day. I get multiple full charges on my iphone and airpods before having to recharge. Works great for my ipad 12 as well. I love being able to charge multiple devices at one. My only negatives would be it takes all night & then some to charge but its worth it considering the ouput you get. Its bulky and heavy. I also did not realize until i purchased it that the usb-c port is strictly for charging the portable device only and produces no output charge.

Pros: Multiple ports to charge multiple items at once. Charges multiple items prior to needing to recharge. Cons: Charger has some weight and takes a while to recharge.

This is a big beefy battery - charged my iphone 15 pro better than a usb-A wall charger from its usb-C port, but not as quick as my usb-C wall charger. Only completed 30-40% charge at a time before the phone heated up and safety measures cut it off (about 20 min) which is quick for a 15W port. Like a whale it’s big, relatively fast, and sleek, but can’t fly. Wish it was under 100Wh so I could pack it in my luggage on flights. Will keep it around for tent camping. I also like that I can turn it off with a double click.

Good product! Larger and heavier than I expected but it charges my smartphones with power to spare. Cords for phones not included but I have spares. Takes a long time to charge but it's great to have on trips when charging on the go is a problem.

In the Box: • Power Pack • USB-A to C charging cable • Instruction manual Pack came with about 70% charge. First-time charge took about 2 hours. Two input ports: • USB-C rated at 5V x 2A • Micro USB rated at 5V x 2A Three output ports: • USB-A (x2) rated at 5V x 2.4A • USB-C rated at 5V x 3A [Note: Amperage on USB-A ports is stated as 2.4A on the device and 2.1A on the product web site and printed materials.] I have also, inadvertently, used the USB-C output port to charge the pack. LED readout quickly provides information on remaining capacity and charging status. Able to charge 2 devices simultaneously. More than enough power to keep watch, phone, and tablet going for long international flights or a weekend off-grid. Pros: high capacity; fast charging; dual output; LED capacity meter; Cons: weight (622 g = 1.37 lb); no power adapter provided;

Took a very long time to initially charge. The number displayed for the percentage didn't show 100% for hours, but eventually it did. Much heavier than I was expecting. Worked very well when we've lost power recently, so it is serving its purpose. Got it on a really good sale. Pleased with it so far.

Be careful when first purchasing this item. Initially it came charged at about 70% and refused to charge above about 86%. After a period of frustration and reading more reviews, I discharged the battery to 0% and it now charges up to 100%. There was no indication that I saw which indicated to do this. I only have moderate expectations about the lifespan of this supplemental battery, but I got such a killer price that it was a very good calculated risk. If it lasts, I'll love it, otherwise I didn't lose very much. Therefore, if you pay a lot for it, I might be nervous about it--my exceptionally special price made giving it a shot a no-brainer.

This power bank is a brick, by that I mean it's heavy and large compared to others I have that perform the same with the same mAh. This lasts a decent amount and charges up my phone really well while I'm on the go, but I really don't grab this as my go-to power bank because of the weight but in the car or on a trip I'll keep it handy. Recharging takes a bit if it's pretty low but you can put it on the charger overnight and it'll be charged up enough for the next day at least for me.

Pros: great power, long lasting. I use it when im fishing and at work to keep my portable bt speaker and tablet charged. It uses less than 20% for a 10hr day with both plugged in. Cons: cannot carry on flights as its over the 100Wh limit. Bulky and heavy, not suitably to carry in pocket.

takes a while to charge but it will charge your device very quickly. havent charge it in 3 weeks and it still holds the same charge level! a little bulky but for good reason.

I bought this for charging while traveling. The charging is fantastic, the lcd display is great,but the size and weight are a inconvenience. I was stoped at the airport in Germany because it was too big and powerful. I had no problems in any other airports. I wish I bought a smaller one

I took a star away because it's just bulky and it doesn't fast charge. Now Energizer didn't advertise this as a fast charging brick, nor did they say it wasnt bulky. What this thing is, is consistent. What does that even mean? It charges your stuff and it doesn't deplete it's battery fast..I normally just keep this in my backpack with a 3ft Anker fast chargj g cable sticking out so if I need to charge anything on the fly it's already ready. I havent felt this thing get hot or swell up or anything so it's pretty solid. This charger Is almost analog in nature, doesn't fast charge but it's charging isn't so bad. This definitely makes a good chArgwr to just have around when you're other chargers have over performed by draining themselves too quickly. This guy will be the last man standing. P.S. remember.....I said this doesn't fast charge.

This is the third portable charger I have purchased in the last 3 years. This first one started to swell after about a year of use. The second one was purchased off of amazon and was too big and bulky and does not have any quick charge capabilities. This portable charger by Energizer is so far the best charger I have had!!! It is able to charge my iPhone 13 very quickly while also charging my apple watch and wireless headphones as the same time! The amount of charges I get out of this product is exceptional for the price I paid. I got it on sale for $34.99, and at that price this is a steal. My only criticism of this product is how slick it is and it should have rubber nubs/grips that help it not to slide off surfaces so easily. I am very happy with this product!!

Very good powerbank. Was on sale when purchased and it can do multiple full charges with its large charging storage. But keep in mind it is bulky and bigger than a phone.

takes forever to charge but lasts almost as long. heavy. would help if the cable it came with was a it longer. still would buy because of durability and able to charge more than one device at a time and still have plenty of juice afterwards

This portable charger was definitely worth the price. I took this on a day trip with me, 8 hours on the road both ways. I used this to charge my air pods, iPad, and iPhone for the whole day. There was still 80% left in the power bank after that all day trip. It might have been a little overkill for this specific trip but it was worth it. Very satisfied with this purchase.

on the heavier side and bulky, good 30ahr capacity, only 15w max discharge and charge capacity, takes overnight to fully charge from 5%

It takes a while to change and thats the only downside. Everything else is really good. I have different brands and this is the only charger that recognizes all my devices when plug in. It's a little heavy but works great. The display is also very helpful wish there was a way to turn off the display while using it, other than that, love it.
