Better than I expected, while stranded at an airport for two days, this battery kept my phone and watch going when there weren’t any charging stations available. And it charged up reasonably fast when I could get to a charging station. (Small airport, limited stations)

Still kicking, Nearly Two Years In

Had to check and see if I'd written a review of this already - turns out I hadn't, which is actually good, since having this thing for a bit under two years makes for a more meaningful review (at least as long as you can still buy it, which it appears you can, though it appears to be on closeout). Suffice to say, this power bank is very, very good: a nice compromise between power output, portability (fits in almost any pocket), versatility (USB-A, USB-C, Micro-USB & Qi-wireless), and fast-charge ability. For almost anyone who's the slightest bit worried about being caught-out with a low phone battery, this one's the proverbial no-brainer. Highly recommended.

Overall charging looks good, but wireless charging is not effective. It can do a full charge of my iPhone 14 at least twice without charging any other.

Charge seems to last quite a while. I uses this in my Travel Pro carry on bag which has an external port to connect the battery to from the inside.

Better Than I Thought

I was skeptical at first... Yes, Energizer has been around for a long time. But usually I stick to Anker products because they were some of the first power banks. And you stick with what you know. But Best Buy gave me birthday certificates and I didn't want the money to go to waste and the power back I had was to big and bulky and required you needing a cord to charge a device but this one didn't since it has wireless charging. And it's amazing. It takes for me about an hour and some change (I use a computer USB charger to charge it) to charge quickly. And it was able to full charge my iPhone and s21 ultra easily before needing to be recharged and it's not as big or bulky. I truly enjoy this product

I needed a new battery since mine are dying, i also have a qi enabled phone. This thing holds so many charges. At least 3 full from 15% charges. It takes a little fiddling to figure out the position to get it to connect

Actually durable took it on a trip and didn’t have to charge it once and my phone and headphones were always fully charged at the end and the wireless charging was convenient when I didn’t have my wire with me.

Truly a portable charger. No need for cables to use the charger with the phone. Qi wireless charging eliminates the need for a cable. Energizer quality. Great device. Good price.

Absolutely the best battery bank I've ever used. Lasts way longer than you'd think plus the wireless charging pad is nice.

Having new phones and wanting a wireless battery charger, this was going to be our new traveling companion.
It wasn't expensive, it was available and it seemed to meet our needs.
Having new phones and wanting a wireless charger, this was it.
Getting it home and unboxing it was a breeze. Everything seemed great until.... I tried to charge my phone. Ugh!
I tried my darling brides phone. Ugh!!
I charged it up incase it wasn't charged enough. Ugh!!!
I guess the Samsung s23 Ultra requires something stronger, more powerful.
Bit it seemed like a nice, well built unit.
What a shame, because the price was nice.
If only it would have worked, it could have been the one.
