Weego 66 Now with Bypass Button - Jump Start Zero Volt BatteriesWeego 66 Now with Bypass Button - Jump Start Zero Volt Batteries

Weego 66.2


Made with the professional in mind, our new and improved Weego 66.2 jump starting power pack is a compact, 2.5 pound workhorse that delivers 660 cranking amps and features a bypass button* that allows you to jump a completely dead battery.  It is rated for large gas engines (10-Liter +) and smaller diesel engines (5-Liter +).

The number one issue with most failed jump start attempts is that a lithium jump starter cannot detect a low voltage lead acid battery. With our advanced voltage detection, the 66.2 can recognize a lead acid battery as low as 0.5 volts and will provide voltage support (known as pre-conditioning) to raise and maintain the voltage of your vehicle’s battery to a level safe for jump starting. *If your lead acid battery is completely dead (between 0 – 0.5 volts), and Weego 66.2 cannot detect your battery, you can use the bypass button to complete the jump start.

With the ability to charge anything from phones to tablets, power 12V tools and accessories, and run a 600 lumen flashlight for hours on end, Weego 66.2 is a great tool to have on the jobsite.

Perfect for: 12V equipment, any gas vehicle, smaller diesel engines.

    Crankenstein starts our big rental equipment including 150′ man lifts.  Totally impressed!

    We’ve even started a few full-size semis that normally need two jump boxes. After 10 years in the towing industry and trying my fair share, none live up to Crankenstein!
