Portable Power Revisited

I decided to revisit my post from a little over a year ago on portable power to see if there were any significant changes in the market. For my methodology, I simply took four of the manufacturers that seemed to score the best in my first post and then pulled models from their web sites. Many of them have specialized models having various features, but I tried to stay with the models that we simply portable power packs without bells and whistles. I then searched for a street price using Google Shopping.

Notes

  • I wasn’t able to find weights for the EasyAcc devices.
  • This methodology is bounded by my first search so there is the distinct possiblity of another manufacturer that I missed in my first or who has appeared on the market since them.

Summary
The bottom line is that little has changed in terms of power density (the best power-to-weight ratios are still around 1500 mAh per ounce), however the best normalized costs have come down (from $.22 to $.15 per mHA).
