UpBright AC Adapter Charger For Vector 450 Amp Jump Start System...

This is a generic charger cord listed by Amazon specifically for the Vector 450 Jump Starter.

www.vectormfg.com

I advise caution when using a standard battery charger to charge a jumpstarter via the main leads. Firstly if there is polarity protection it probably won't work and secondly the heart of the jumpstarter is a sealed lead acid battery which does not usually tolerate high charge currents without shortening the life of the battery.
This type of battery needs either the low charge current supplied by the original charger or similar or a sophisticated regulated charger.

If using a standard charger avoid using a high performance type and use only the type that provides a trickle charge.

I HAVE A NEW SUCH PRO UNIT WHEN I WENT TO USE THE CHARGER THAT CAME WITH IT IT WILL NOT WORK CAN I GET ANOTHER CHARGE UNIT SEN T TO ME ??

Hi.

The Vector jumpstart system listed does not use a power adapter. Replacement parts such as cords and clamps can be obtained calling the toll free number: (866) 584-5504.

Regards.

Radio Shack has a multi purpose unit that is adjustable for many applications.
Remember to take the unit in with you

google the name and model #. The home website should come up in search. Go to site, and look in support, or replacement parts.
