During our testing, we noticed the unit prevents accidental shutdowns while driving. This safety feature keeps you from unintentionally killing power by pressing the remote in your pocket. The system also delivered on its promise to help with parasitic power drains.
One quirk we observed was that disconnecting the battery resets vehicle electronics. After reconnection, we had to reprogram radio stations and adjust climate control settings.
The remote occasionally required multiple presses to reconnect power, though disconnecting worked flawlessly every time.
For anyone dealing with mysterious battery drains or wanting an anti-theft measure, this 240A kill switch offers an affordable solution without needing to find the exact electrical problem.

The 240A rating handles our truck’s electrical system with no issues.
During cold weather (-10°F), the switch continued working perfectly, living up to its claimed operating range.
We appreciate getting two remote controllers in the package – one stays on our keychain while the spare is safely tucked away.
For vehicles with parasitic draw issues or that sit unused for periods, this kill switch provides excellent peace of mind. The automatic cut-off feature alone has made it worth the investment for our occasionally-used truck.
Buying Guide
When shopping for a remote kill switch, there are several key features to consider. We’ll help you navigate the options to find the best fit for your needs.
