The TENMA portable power supply (72-2660) offers bench supply capability in a backpack friendly package. The single output is capable of 45 watts with up to 30 volts and 3.75 amps out. The built-in USB ports offer an easy way to power 5 volts Arduino or Raspberry Pi projects while limiting their current. See how this portable supply performs, the things the Bald Engineer likes about it, and the points to consider before buying.

    Good review James. I liked the mod you did to fix the "off" feature.

    A power supply like this would be great addition to a portable tool kit for many technicians.
