EvTEK Chargers are available either tethered or untethered. If the charging cable is attached to the charger, is it is known as tethered. If the cable is separate from the charger it is known as untethered. The way you plan to charge your EV will determine whether you choose a tethered or untethered charger.

Tethered Chargers

  • There is no need to buy a separate charging cable. The device comes complete.

  • It is more convenient as the cable is always there ready for use.

  • EvTEK Charger cable is a flexi spiral heavy duty cable so it always looks neat and tidy.

  • EvTEK 4 metre cable length is ideally suited for virtually all electric vehicles.

Untethered Chargers

  • If you plan to charge your EV both at home or when out and about then having an untethered charger is a better option. You will require a separate charging cable to be available in your EV if you install an untethered charger.

  • Some public charging stations may not have charging cables attached and you would then be required to use your own. EvTEK can supply separate 5m and 7m long cables if required.

Remember – Untethered cables can be easily run over by your vehicle if left on the garage floor.


Here are some things to consider when choosing the location for your charger.

DISTANCE – consider how close your nearest mains electricity supply is to where you want the charger.

CABLE LENGTH – you will want the cable as near as possible to the charging port for your vehicle. EvTEK Chargers come with spiral coil heavy duty cable which extends 4 metres in length which is the ideal length for the majority of electric vehicles.

HEIGHT OF THE CHARGER – We recommend the charger be installed 1.20 metres from the underside of the charger from ground level.Only a licensed and certified electrician should install your EvTEK Charger.Before you install your charger you should determine where you want to install your charger.

The important issues to consider when installing your EvTEK Charger are -:

WIFI SIGNALEvTEK Chargers all have WiFi monitoring so it is important to connect to your home WiFi and check that your signal is strong enough in the location you want to install your charger.

INSIDE OR OUTSIDE – The charger can be installed either inside or outside if required however it is important to consider the distance from your power supply if you are installing the charger externally.


More than a quarter of EV drivers charge their cars as soon as they get home, instead of waiting for the cheapest time to plug in. Only 10% of EV drivers wait to charge their EV when the power is operating off peak and when the power cost is at the cheapest.

HOME CHARGING DURING OFF PEAK TIMES – Charge your EV at off-peak times. If you charge during peak times, it will cost more. If you’re not sure check your electricity account for off peak rates and also directly with your energy provider if unsure as to the best times. Typically, the worst times to charge are between 6am -10 a.m. and 6pm-10 p.m.

LOOKING AFTER YOUR EV’S BATTERY – Avoid running your battery lower than 20% and set it to stop charging at 80% unless you need the range for a longer journey, as the first and last parts of the battery take the longest to charge. This is also good for battery health and longevity.

HOW TEMPERATURE AFFECTS CHARGING – If you live in a colder climate, finish your charging as close as possible to the time you leave home in the morning. As charging warms the battery and you’ll have more range from the same amount of energy.

If you live a warmer climate this generally mean you get more kilometers per charge, however, above 25 degrees Celsius, range tends to fall away. If it’s hot out, make an effort to charge in the shade. In extreme heat or cold, keep your car plugged in (but not necessarily charging) to allow the battery temperature controls to keep running.
