cheeseI'd read that review again. Here's the summary for the Satechi:
"At this point, however, it’s the most expensive power bank in the group (at $60) with the lowest capacity (at 10,000 mAh). It charges slow, too. It was a great pick a year ago, but times have changed, even if the Satechi’s price hasn’t."
They compare not only the capacity, but also the size and features.
