    This was a great charger. It works well for charging my phone throughout the day which was what I was hoping for. The charge on it is strong and something that definitely helps to get me through my day and the tasks that I need to complete without worrying about losing ground because of a low battery on my phone.

    I’m very happy with my purchase. I bought it to charge my iPhone during a trip. It is slim, compact and light. It charged very fast compared to my other battery backup. I can charge my iPhone twice with it in one day. This allowed me to take lots of photos, use apps and make calls. I wish it came in different colors.

    The Energizer portable charger is a must have for people on the go. It's slim design makes it easy to carry for all day use. It stays charged all day. It charges my iPhone and Airpod charger really quickly, ensuring my devices are always working. Great product for everyone on the go. Don't leave home without it.

    Bought this with my Best Buy pts and it’s been great. It didn’t charge when plugged into the wall so I had to charge it through my laptop other than that it’s charges up my phone faster than if I had it charging in the wall. Love that is slim and lightweight.

    This power bank worked well, and provided me about 3.5 full charges for my Galaxy S21. I did have to buy a new cable, since the one included was for the previous-generation port. The power bank has a great feel to it and charges my phone quickly. This seems to be a better value when it comes to power versus other brands.

    I've had this portable charger for a year or so now, pretty good for when I need to make big trips and haven't had time to charge my phone. No longer need to worry about conserving battery and can do what I need when I need. Charging does take a while, but it lasts for quite a time too.
