General Questions

VoltSafe Winter is specifically designed and tested for use with Engine Block Heaters – it is not recommended to be used with any other electrical devices.

Currently we do not sell the parts separately.

The VoltSafe Winter block heater cord is designed for outdoor use and only for block heaters. 

12 Month manufacturer warranty: any defects in material and workmanship will be repaired or replaced at no charge to the buyer, provided return of product is made no longer than twelve months from the date of delivery.

The VoltSafe Winter device is carefully designed to reject standard magnets.

The VoltSafe Winter device is carefully designed to reject standard magnets. As such, it will not turn on if a standard magnet is used with it.

The Winter unit will run on an absolute minimum of 85V AC. If the ‘smart’ plugs are limiting the power with a 50% duty then the mains voltage drops to 60V. This will not allow the VoltSafe unit to activate.

Note: If the ‘smart’ plugs are designed in the same way as light bulb dimmer switches, those can introduce high frequency noise that will damage some of the VoltSafe Winter’s internal components over time. Damage to the units in this way will not be covered under warranty.

App Issues

  1. Ensure your VoltSafe Winter unit is turned on and the blue light is blinking
  2. Open the VoltSafe Winter app on your smartphone
  3. Once the app shows you are connected to the device, follow the instructions on screen to set the on/off times

Yes, currently the timer has to be set every time. We are hard at work to make improvements to this feature, and your feedback helps!

Yes, when the (active) cord is unplugged and the unit is removed from power, the device resets, and the timer schedule will need to be resent.

Currently, the timer schedule will have to be set every time the voltsafe unit is powered off and on. 

Yes, you may set multiple on/off windows for your device within a 24 hour period.

Currently, devices will appear as “VoltSafe Winter” but will soon have the option of renaming a device to better identify it.

Currently, VoltSafe Winter is not compatible with any smart home platforms. Stay tuned, though, as we’re working hard to add this feature for sometimes in the future.

Hardware Issues

If the solid white light does not turn on when the two halves of the VoltSafe Winter unit are brought together, please do the following:

  1. Open the VoltSafe Winter app on your smartphone and connect to the device
  2. Click the help button in the top right corner
  3. Click on “My Plug isn’t turning on”
  4. Follow the onscreen instructions to refresh your device

If a solid white light remains on when you unplug the cord, please unplug the unit from the wall and contact VoltSafe Service.

A flashing blue LED light indicates that the device is in pairing mode and ready to be connected to.

Once it drops below -35°C , we suggest that you skip the use of the timer and just leave the block heater running. While it’s designed for winter, your VoltSafe unit is still a smart device and may struggle to turn on once it’s internal temperature drops below -35°C .

If you connect the two ends (as usual) after it’s sat in sub -35°C temperatures for most of the day, the white light might not turn on. In that case, the unit is too cold and will need to be warmed up a bit. Bring your VoltSafe inside for a few hours and try again. That will do the trick. You can also take the cord with you when you drive. Once the white light was on for 30 seconds (after first connecting) the current running through the VoltSafe unit will keep it warm enough.

While this may not save any electricity, we’d rather you be safe than sorry and wake up with a car that won’t start.
