12-Volt Vehicle Power Supplies

When you have a high-performance car stereo, you might want to show it off even if you’re not going anywhere. However, playing these watt-intensive systems can drain the battery fast. A 12-volt power supply for your car amplifier and receiver lets you enjoy some tunes while hanging out with friends in the garage, grabbing attention at a trade show or any other time the alternator isn’t providing amperage. Run the sound system directly off your 12-volt power cell or make them the go-between when setting your car stereo for an added power source.

A high-current car audio power cell has other uses, too. It’s a great tool for bench-testing 12-volt electrical equipment to diagnose any problems. Certain power banks are also a great back-up battery for jump-starting your car or running emergency lighting. You’ll always have enough power when you keep a spare pack from OnlineCarStereo.com.

Top Power Banks for Car Audio

No matter how many watts your sound system needs, there’s a 12-volt DC power supply that can provide it. We have a wide selection of Kinetik AGM car audio cells for every level. They range from 400 watts to 3,800 watts of output and can also be used as a secondary or replacement car battery if yours gives out. These power supplies are better-regulated than battery chargers so they won’t cause humming. You’ll also find universal multi-function power banks that will connect to the battery or directly accept smartphones and laptops. They recharge via a wall adapter or cigarette lighter adapter so you can power back up in a flash.

Keep the tunes going after the engine is shut off by adding a 12-volt power supply to your car audio collection. We’ll help you find the right power supply with free shipping on all orders. Each purchase is backed by a 60-day guarantee and all manufacturer warranties.
