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

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.

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.

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.

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”.

Pretty good battery for the price. Long lasting life plus different cable connectivity options. Only downside is that it is a little on the heavier side.

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.

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.

This was a gift for my husband and son. They needed a portable charger. Carrying multiple chargers in the city resulted in lost or stolen chargers throughout the year. This charger is compact, fits in type of bag, and can charges 3 devices at once. They mainly charge ear buds, small tablets, and smartphones.
