We needed it for our trip to Japan as our constant use of our phones for navigating and video taking drained our batteries fast. Perfect for our family as this backup held a lot of reserves and charged our phones fast. You need to reload it during the night and carry it in a backpack. Just have the wire hang out of the bag and plug the phone while on the move. Perfect for the main trip navigator…..which was me.

I bought this initially to use at a music festival (it worked fantastically, charged my phone from 20 to 90 5-6 times) but now i use it on my day to day life. My son descided to chuck it in the pool the other day and its still chuggin along! I will be purchasing a second just to have a back up back up battery (and i plan to go to more festivals)

Wow! What a great product! I have used this on numerous occasions when our phones were low on battery and we were able to charge both phones quickly, and still had 83% battery left. Once charged, it stays charged until you use it again. Great price for peace of mind. Now, I always carry it with me when I leave the house!

The charger brings your phone to full charge quickly even if the battery is very low. It is a little bulky/heavy but not as large as other fast chargers. Excellent value for the money would highly recommend!

Hi HollyH, We’re thrilled to hear the charger is delivering fast and reliable performance for you! While its larger capacity adds a bit of weight, it’s great to know it still feels more compact than other fast chargers. Thanks so much for the recommendation! --Energizer PowerPacks Service Team

It was a last minute purchase due to needing a back up charger immediately. I had no idea it would charge all my devices at once and its easy to carry in my backpack or large bag.

I got this purchase for my uncle. He absolutely loves it ! It is very useful to him as it charges fast and the battery itself does not drain so quickly. I will be getting some for other relatives.

It is really good. The only reason I gave it a 4 instead of a 5 is because it is heavier than I thought it would be. It is also hard to turn off at times. I appreciate how it tells me how much charge is left. It is a good product.

I bought this Energizer power bank because of storm outages. I just started to use it. Wired USB A connection fast charge took my iphone from 25% to 80% in less than an hour. only used 4-6% of bank power. The wireless charge for iphone is much slower at 7.5 Qi and uses more bank power as well. I gave it 4 stars because of the slower wireless iphone charge rate. Overall it will provide great power backup for my electronics. So far so good

I LOVE this charger. A little bulky to carry in purse, at 14.6 oz, but it is amazing! I use it at home to charge my phone & tablet and it is lightning fast. I can get several full charges out of it, and it recharges fast, too. Highly recommend if it fits your needs!

Pros, definitely does its job and fast. Love the digital screen to show level of power. It is indeed heavier than anticipated, love that option of exterior tap to charge by laying a fast charge phone on top. Definitely can’t recharge with a fast charging outlet, so keep that in mind

Good powerbank with enough juice. Wireless charging does not have a good hold and is primarily to charge when stationary. USB-C port is fast, LCD display is good to know exactly how much charge you have left. I got it on a sweet deal on Thanksgiving.

Power bank works better than expected. The wireless area is quite wide and does not need to be exactly positioned.

I needed it for a trip and it holds up quite nicely. The charge lasts more than 3 days before it hits the halfway through the battery life. An annoyance was i could never tell if it was actually on since pressing the power button made it blink and once i let go it would turn back off in a matter of seconds. I just guessed that it was working and it paid off.
