Great resource for portable power. Solid construction, easy to operate and dependable. I have this in a work van to provide power for operating a laptop, recharging batteries, running tools like a small air compressor and lights. Has come in handy in using my tools in assisting stranded motorists to get them back on the road. I like the battery saver feature that will not let it discharge my vehicle battery to the point of not having starting power.
It's easier than ever for do-it-your-selfers to customize sound and security systems, so you don't have to rely on factory gear; aftermarket accessories improve driving enjoyment from vintage add-ons like speaker boxes for classic sports cars or specialty stands for satellite radios that include adjustable cup holders. The list with hundreds of products goes on and on as more niche players create more options for car audio, video and navigation.
