Press the ‘Program’ button, then use the ‘Week’, ‘Hour’ or ‘Min’ buttons to select the days, hours and minutes you would like your timer to stay on for, as well as the time you’d like it to switch on. Then plug your device into the timer. Do timer plugs use a lot of electricity? Yes, although standard travel adaptors must never be used with an EV granny charger. Most are only designed to power low current appliances and some often dangerously do not connect the earth pin. Dedicated final circuit with over-current protection (e.g. you can't use or spur off an existing ring circuit).
When purchasing an EV, we would always recommend the professional installation of a wall charger. This ensures that the supply used has been tested to be safe and will achieve a faster charging time. When not at home, it is best to use a public charging point. Most EV manufacturers recommend that granny charger are not used as the sole means of charging. The first thing I like about this plug in timer is how simple it is and how smart it looks. Some countdown timers are best kept hidden away, but this one actually looks good on the wall! And with just three buttons to fiddle with, it’s easy enough for anyone to get the hang of.
Type 2 untethered chargers have a type 2 connector fitted to the unit itself, not to a permanently connected cable (left). They are common for both domestic and public chargers. A separate type 2 to type 2 cable, available in a range of lengths, is required to connect the charger to an EV. Most are rather long. Think of a cable like a water pipe. If you want high pressure at the end of your 10m garden, you’re not going to achieve it if you use a hosepipe the size of a drinking straw! The longer the distance, the larger diameter you need to sustain the same flow. This principle is the same for electrical cables. Manufactured from cable which is not sufficiently large in diameter (normally 1mmsq or 1.25mmsq) to handle the relatively high sustained 10A current required. One of the benefits of a plug in timer is that they use very little electricity. In fact, you are unlikely to notice any increase in your electricity bill. Domestic electrical installations can deteriorate with use and age. It is therefore important that a periodic inspection is carried out every 10 years for an owner-occupied home and every five years for rented properties or HMOs.
The data sheets for 1.5mmsq H07RN-F cable generally state a max current of 15A. If the cable is a sensible length, the manufacturers recommended max current is nowhere near exceeded. In contrast, a tethered charger (right) has a cable permanently connected, with a type 2 connector on the end. A type 2 to type 2 cable cannot be used to extend the length of a tethered charger, as the international standard has a safety mechanism which prevents the charge from commencing if two cables are joined. What is a granny charger? The large screen makes things easy to read, and it even has its own battery to keep the settings in case of a power cut. You can use it as a countdown timer, which makes it ideal for setting a bedside lamp to go off even after you’ve fallen asleep! It’s these little things that will save you money on your electricity bill.The onset of charging can be delayed by 1-12 hours from the button being pressed, with the limitation that a time cannot be set to stop charging. Most electric vehicles (EVs) are supplied with a portable domestic charger designed to charge the vehicle when access to a charging point is not possible. Rather confusingly it is commonly referred to as a 'granny charger', as it is a lead to use when visiting relatives such as your granny! Wi-Fi enabled control unit built into an EV extension lead, providing live and cumulative kWh readings via the Smart Life app. The unit also allows remote control and timers to be set.
Irrespective of whether an extension lead is used, it is important that you consider how safe the supply may be before plugging in your charger. Type 1 - Designed by the Japanese manufacturer Yazaki, the connector has 5 pins. It was predominantly used on vehicles from Asia, and is mainly found on older EVs within the UK e.g. Vauxhall Ampera, Mitsubishi PHEV. It allows single phase charging at 3.7kW-7.4kW AC. Plug in timers are a really handy product to have in the home. They can save you money, deter burglars and ensure you come home to a warm, bright house on cold winter nights. Timer plugs are also ideal for specialised functions such as Christmas lights, greenhouse heaters, grow lamps, fish tank pumps and any other item that needs to be turned on for certain periods of time. When choosing a plug in timer don’t forget to consider the following features… Digital or Mechanical
You can only compare up to four products at a time.
Type 2 - Designed by the German manufacturer Mennekes, the connector has 7 pins. It was adopted as the EU standard for EVs in 2014 and is therefore the most common EV connector in the UK. It enables single and three phase charging at 3.7kW-7.4kW AC.
