Customer Ratings & Reviews

This charger has a sleek design, easy to transport in my bag and packs great power. It takes a bit to get fully charged but once full, is a lifesaver. It can charge multiple devices at the same time. I love the digital battery percentage so I know when it needs to be charged. It's small design makes it convenient to have with me on the go, which is when I need it the most.

This energizer power bank is a lifesaver. Works really well, super easy to use. It’s about the size and weight of the average smartphone so it doesn’t feel like a hassle to carry. This is my third purchase of this brand for power banks and they’ve all worked wonderfully. I definitely recommend it because it charges your device very quickly and it’s ultimately convenient to use. I pay around $17.99 + tax = $20 and it’s honestly worth it. The price was more than reasonable and okay, dare I say it was a ‘bargain’ almost. I give it a 5/5 rating

It works well for charging, I get almost 2 charges out of it for my iPhone 17 pro. But for the weight and compared to other 10k mah portable chargers there are better out there for sure. It does the job though if you are on a budget and need one. Slim for fitting into backpacks as well but would recommend the NiteCore 10k or 20k instead as these are lighter and just as, if not more effective portable chargers. No screen, can charge from either usb-c port and much lighter. My NB20000 is only 80 grams heavier than this energizer 10000

I've used a lot of portable chargers over the past 10 years and this one is the best I've used for the price. I know reviews are ehh but I'll try to do my best. For the $13 I paid for one, you get a name brand 10,000 mA portable charger. With more than enough types of ports for everyone. I use USB C for everything and this has USB C input and output(same port). For those who still have micro USB portable chargers, this will be a good replacement since it can charge that way too. It isn't a crazy brick nor is it the smallest for it's capacity, but it's fine. It fits in my pocket and my bag and that's all it needs to do. Like I really have no complaints. I bought two, one for me and one as a stocking stuffer for my partner. I've been using it for like two week mainly at work to give my phone a boost during lunch and it's great.

This Energizer portable charger is light and compact. It reliably charges my iPhone 15 twice, taking it from 10% to 100% each time. However, I have a couple of issues. First, once the charger's battery level hits 15%, it drops to 0% very quickly, in about 10 minutes. Second, the power button is placed right near the output ports. This is a problem because if you use your phone while it's charging, there's a high chance you'll accidentally push the button and turn the charger off without noticing. It would be much better if the power button were located on another side of the device.

This Energizer MAX 10,000mAh power bank has quickly become my everyday carry. It’s compact enough to fit in my bag, yet powerful enough to fully charge my phone 2–3 times without breaking a sweat. The 15W USB-C port is fast and works great for my phone, GoPro, and even my wireless earbuds. Having three ports means I can charge multiple devices at once—super handy when I’m traveling or working on location. The LCD screen is a game-changer. No more guessing how much juice is left; I can see the exact percentage at a glance. Build quality feels solid and durable, with a clean black finish that looks professional. I’ve even used it in light rain without any issues (though it’s not waterproof, so I wouldn’t push it). If you need a reliable, versatile, and travel-friendly charger, this is it. Energizer nailed it with this one.

Good size and weight portable charger. The power bank itself fully charges in few hours and charges phones and accessories fairly quick. I like how you’re able to charge multiple devices at the same time.

This tiny little Battery pack has saved me on many different occasions. I was very surprised that there is virtually no power loss when not in use. Equipped with an easily seen display As well as USB and USB-C. A definite must have for anyone who goes on hikes or camping trips!

Great battery. Charges quickly, faster than my older Li batteries. So far have been able to charge my iPhone 13 4 times as well as ebuds. Still has a charge and the charge level indicator is great. Better than my old batteries that gave me 25% levels of power state. Nice size to carry.

I bought 2 of these because I don't have any outlets available near me or available in the livingroom. These power banks charge my phone quickly and have been used without fail every single day!

This powerbank works perfect and extends my phone's battery when I'm not near an outlet to charge my phone. I love the carrying bag. I keep the cable inside so I don't lose the cable that came with it. What I love the most is it's a sleek and small design and fits in my bag. I will be ordering another one and probably extras as gifts for my family. Thank you

I bought it expexting a great product. Well i got one. It sleek design is nice. It charges great. This is my first time trying one of these. Im truly happy that i did purchase it. Its made by Energizer. I expected great things with it and i got what i expected. It chsrges fast. Its exactly what i needed and wanted.

It charges pretty fast and you still have a good percentage of a juice left. It charges back up pretty fast too. I like the fact that it shows you how much is left with the numbers displayed in led format.

Charges my phone very fast and the lcd display is very helpful when the power bank is charging, does not heat up and stays cool, fits very good in pockets

Charges fast, holds charge well when not in use, can fully charge my phone from dead 2-3 times from a full charge.

A handy device to use when a standard electrical outlet is not available for charging. With a simple plug-in cord this external battery charged my cell phone quickly. It holds its power for several days while awaiting use too. It would be convenient if it transferred power wirelessly and had a velcro strip to marry cell phone to external battery. But this product did what was stated quite well.

Bought on a whim to get me thru for a concert and without even getting to fully charge it befor ei had to use it, my expectations were by far exceeded. Also the digital screen makes it suuuuuper easy to know how full the battery life is!!!

So lucky got this power bank on the right time before our trip to Spain really happy to have this highly recommended.

This is a nice slim portabke charger and it was on a good sale. Like that it comes with LCD screen and usb C fast charging.

This charger works great, comes with a charging cord and fits easily into my purse. I play games on the bus and use my phone when we are out shopping and with friends to share pictures. I wanted something small - this works. It charged quickly and is what I needed.
