|Summary of the main features:
This USPS scale differs from PS-100 only in the weight range. Supported weights go from .1 ounce to 5 pounds, with .1 ounce resolution. It does not support AC adapter as a source of power, it only runs on 3 AA batteries. For other characteristics, read the previous review. The price of this scale is currently the same as the 10 lbs one (PS-100), so that postal scale is a better option. If you want this one, best price online is on Amazon.com.
