New 120-360 W portable chargers of the NPB series

  • 27.10.2021
  • 225

The first generation of MEAN WELL chargers of the PB family (120-1000 W) has been on the market for over 20 years. Technology does not stand still, so to meet the demand for more cost-effective and relevant chargers MEAN WELL has developed two new series of portable power tools: NPB series and NPP series (120-1700 W). Models with a capacity of 120, 240 and 360 W – namely NPB-120, NPB-240, NPB-360 – were the first to be put into serial production.

The new series have a completely new scheme, which allowed MEAN WELL to make these chargers as compact, efficient and flexible as possible. Compared to the previous generation of the PB-120 / 230 / 300 / 360 series, the main differences of the new portable battery chargers are their smaller size (except for the 120 W model), higher efficiency (up to 93%), the ability to adjust the output voltage and current, variety in models with different charging connectors and more competitive prices. To quickly get acquainted with the differences between the new generation and the old one, see the table below:
