Universal 3-12V 30W adapter with USB
The ProTechTrader VPOW312-30W is a 30 watt universal AC DC power adapter supplying 3 to 12 volts at up to 2.5 amps. It includes a USB port rated for 1.0 amp charging and eight interchangeable DC tips covering 5.5mm, 5.0mm, 4.0mm, 3.5mm and 2.35mm barrel sizes. The reversible polarity design allows centre-positive or centre-negative operation by flipping the tip.
Suits multi-voltage devices; not for high-draw gear
This adapter suits routers, speakers, monitors, cameras and similar electronics that require 3, 4.5, 5, 6, 9 or 12 volts within the 12 watt limit per voltage. Buyers needing more than 2.5 amps total output or a USB port delivering above 1.0 amp should look at a higher-capacity supply instead.
Reversible polarity tips decide fit
The single specification that decides compatibility is the reversible polarity tip system combined with the eight included barrel sizes. You must match your device's exact jack dimensions and required centre polarity before purchasing.
