How It Works
How It Works
- Connect the Clamps: Clip VoltCore's clamps to your battery terminals in any order — reverse polarity protection prevents mistakes automatically.
- Check the Light: Green means ready to boost. If the battery is stone dead and shows red, hold the override button 3–5 seconds to bypass the low-voltage lockout that causes other units to give up.
- Start Your Engine: Press the power button, crank your engine within 30 seconds, then disconnect and drive. Most vehicles start on the first attempt.

VoltCore
Always Ready When Your Battery Is Not
Override Mode for Stone-Dead Batteries
VoltCore manual override bypasses the 2V lockout, starting engines that competing units refuse to touch. Confirmed in independent dead-battery tests.
12-Month Charge Retention in Storage
VoltCore holds a usable charge for up to 12 months and tops off in under an hour.
Power Bank and Emergency Light Built In
Beyond jump starting, VoltCore charges phones and tablets via USB and throws a bright 7-mode LED beam — useful long after the emergency is over.
Climate-Adaptive Charging
Cold weather is the top battery killer. VoltCore delivers full cranking power down to -20F so winter never leaves you stranded.
What our 17,000+ Customers say
Based On Real and Honest Experiences
It saved me from calling roadside assistance last November. I connected the VoltCore in a dark parking garage, hit the button, and drove home. The VoltCore is the one item I will not drive without.
My car had an electrical fault draining the battery for five weeks straight. VoltCore handled the jump nearly every day and still showed nearly a full charge. It is one-payment insurance with no wait time.
Skeptical after two cheap units that failed in storage, I bought VoltCore half-expecting the same. First use on my F-250 after a cold snap and it cranked right over. Now I keep one in every vehicle.
