Customers like the size of the power bank. They say it's compact, fits in pants pockets, and is near perfect for a quick recharge without being attached to a wall outlet. Some customers also say the size is somewhat large. The short length is perfect for in-bag charging, and the grip is perfect.

Customers like the travel of the power bank. They mention it's perfect for travel, or if you don't want to be stuck next to a wall. The power bank is one of the best portable banks in the market, and it works very well. It's slim so portability is not an issue, and can be stored in a bag easily. It is very convenient to use when traveling, and the lifespan is pathetic.

My power bank suddenly split at the back
Hey guys thanks for all you do all this while? I can't appreciate the reliability of your power bank enough. My power bank suddenly split at the back and I'm scared to charge it with the fear that it will explode, what should I do? Thanks.
Thank you for your feedback

5.0 out of 5 stars Heavy, but great back up battery! Anker for the win!
Reviewed in the United States on August 31, 2023
**Video and Photo show this after having it a year. Still going strong (and only a bit beat up)**
I have used Anker products for a while. When I went looking for a more powerful back up battery, I started there. I needed something that could power - at one go - an Ipad, multiple phones, and a myriad of those electronics. This model does all of that. It holds up to the description, and I have had no issues with charging/recharging it like some of the reviews have mentioned.
It is relatively compact which makes it a great addition to my purse (both for everyday use and travel). The only thing I will make sure to mention is that it is not as lightweight as the smaller models out there. You can't get the charges it provides without a bit more weight (at least at this time). Just make sure you are aware this isn't a light weight model.
