Sigma is a dealer for a number of different computer power adapter systems. We primarily recommend Lind Electronics for all computer power supplies. Lind is an industry-leader and makes very rugged, reliable power supplies that are backed up with great service.
These adapters are primarily used to power your computer from your vehicle. One cable plugs or wires into your vehicle’s electrical system, and the other provides the proper voltage to your computer or tablet.
If you need a power supply for your laptop, tablet, or other mobile computer, please contact us and we can help choose the best one for your application.
