Jumper cables are unreliable at best. It’s about time for a change. This DIY will show you how to make your own solar charged car battery using pretty basic items. The one thing you’ll probably need to pick up is the solar panel, and to tell you the truth, not much more is needed.

The panel is connected to the car battery with a voltmeter. When the voltage reading is around churning at 14V, your battery is charged. This is a true ghetto-tized DIY if I ever saw it. And even better, it’s eco-friendly. — Andrew Dobrow

Imagine this. You wake up half an hour late for work, jump in the shower, swallow down a bowl of cereal, run out to your car with a few minutes to spare, only to find that your car battery is dead. It’s happened to some of us, and the rest of you, it will happen eventually (though we hope not!). The Sunsei SolarCharger 135 by ICP Solar (no, not the rap duo) can make sure you’re not left in the cold if you were to accidentally leave your lights on.

The Sunsei, made to collect solar rays through glass, sticks to the inside of your windshield with its included suction cups. Just leave your car in the sun and you should remain fully charged and ready to go, even if the car hasn’t been started in a while. The Sunsei uses “trickle down” power which will ensure your battery is always charged, yet not overcharged. Even more cool, the Sunsei will work on any 12-volt vehicle. Including boats! Keeping your vehicle charged, even in the most extreme of weather conditions. — Andrew Dobrow
