## Customer Reviews

### ⭐⭐⭐ 







  
  
    Can be finicky, but nice once you find a suitable power source.
  

*by D***Y on Reviewed in the United States on November 25, 2018*

I Use this for long astrophotography sessions as it is easy to run a battery down while shooting Deep Space Objects for hours.  I have found the adapter is pretty finicky for the power source used.  Most of my battery packs seem to not work well even though I only use higher end packs.  I have also found some car USB charger adapters will cause an interference line in your images.  The camera wll turn on with any battery pack that I use, the issue is the camera shuts down while shooting in bulb mode which is needs for long duration astro-imaging with repetitive shots using an intervelometer.I have found that my portable battery packs that are Quick Charge 3.0 compliant seem to work reliably with this adapter.  I also found that I have a USB car charger that is USB QC 3.0 and it works well as well.  The bottom line is I would not buy this unless you have QC 3.0 compliant adapters to run this with.Buy with caution and I would make sure your power sources are USB Quick Charge 3.0 compliant.
