Editor's Pick: If your car has been sitting in a garage or on the street too long and won't start, just clamp this on the battery and you're good to go — no need to wait for roadside assistance. The 16000mAh capacity doubles as a portable charger for your phone in a pinch, and the built-in LED light has three modes, handy for nighttime car repairs or camping. The waterproof, drop-resistant shell takes up barely any space in your trunk, and it starts reliably in both hot and cold weather.
