The Goal Zero Power Bank comes well packaged and is basically a plug and play device. When I received it and plugged it in to charge, it was already charged at over 90%. I left it charging for an entire day and when I checked it, the charge was 99%. At first, I was surprised that it was not at 100%, but it has achieved 100% after subsequent charges.

The display provides a lot of information on status and input/output as well as the options as you toggle through the screens that provide information for the customizable functions. In the photos below the first one shows the display when there is no load, and the last one shows the display hours later after using a tablet while it was plugged into the AC port.

I use the ports exactly as they were set up when I received the device since they meet all of my needs as they are. I like the individual buttons to turn on/off the Qi wireless charging function and the AC power, etc.

My only concern with this Power Bank is shown in the photo below. If you are using a wall adapter that is wider than the device then it is no longer level, and the bigger the adapter the higher off of the surface the device will be.GoalZero Sherpa Power bank 17

What I like

  • The build quality
  • The versatile connectivity ports
  • The sleek design
  • The power delivery capacity
  • The Qi wireless charging

What I’d change

  • Maybe the ability for the built-in AC port to be able to swing upwards to accommodate larger AC adapters.

Final thoughts

A few of the power banks that I own are quite versatile, but none as versatile and portable as this Goal Zero Sherpa 100AC Power Bank. The dual in/out USB-C power delivery ports along with the regular USB ports and the AC port make this perfect for my use. The Qi wireless charging takes it over the top for me. The only minor issue that I have with it is that the obvious way to use it is flat on a surface, and since the AC port is slim and fixed, anything AC plug that is thicker than the device raises it off of the surface and puts the weight on the AC plug. It can also possibly make using the Qi wireless charging difficult if the level that it is raised to is too steep. Otherwise, this Power Bank is a win and gets a well done and two thumbs up!!
