    Really no Complaints

    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.

    Good pack, good price, its super nice to see the percentage left. Slim and portable makes a great travel accessory. Only downside is that it has a micro usb instead of usbC. Still a good product

    Very good for its price. It charges to full in about 1-2 hours and is worth a full charge and a half (tested on iPhone). Not bad if you’re ever caught without power and need a quick charge.

    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.

    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.

    Not actually USB-C charging

    Despite claiming to charge via USB-C and containing a USB 2.0 to USB-C cord for charging, the actual charging port seems to be a micro-USB port, and the provided USB-C cable does not fit in it. That said, it came with a 77% charge and seems to be working well so far.

    Energizer Power Bank Lifesaver

    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’s a solid battery. I use it to charge my phone and other devices while I’m on the road. Ended up getting a more powerful model so it would last longer but this is great for charging a couple of devices.

    I brought this charger just in case the electric power goes out in a bad storm. But I had to used it the very next day because I forgot to charge my phone. It charged my phone very quickly.

    Product works very well. It's very easy to use and it quite durable (can be carried around in a backpack, and it light enough to be carried in a pants pocket). I haven't even had this for a month, and it's already helped me keep my phone (and even my smartwatch) alive after some serious daily use.

    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!

    You have to start using it at first I was wondering why the charge wouldn’t go up. You have to deplete the battery down and it will charge to 100%.Mines charges fast. Quality material. Sturdy would recommend.

    I love my Energizer Power Bank. Very easy to use. The instructions are simple and most of all it lasts a long time. I’m considering buying one as a gift for a family member whose phone seems to die rather quickly. This is an awesome product. Kudos “Eveready”.

    External battery

    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.
