It all depends on your needs. I'm retired, in a rural area and go into town once a week for supplies. Grandpa has all week to plug Granny.

I had a BMW 330e for two years which I charged every night with the supplied 13A plug. I now have a Tesla Model 3 AWD Long Range which I've charged the same for a year, both on a cheaper overnight tariff. It all depends on your daily mileage and charging needs. Plus Granny chargers are a handy temporary or emergency measure. I have now installed the Tesla home charger which I've had in the loft since buying the car. Speaking as an electrician, please do not charge an EV with an extension lead without limiting the current to 6 amps. They are not designed for continuous, long term use at higher currents. And also, always completely unwind the coil.

Hi Ian, second day I got my model Y, my home wall charger went pop. It took 4 days for the company to replace under warranty. The granny charger saved the day to top up overnight, enough to get to a supercharger if required. Thank you granny.

Maybe I'm in the minority but we ONLY use a granny charger for our car (we are in New Zealand so 240v, 10A) with no extension cable and brand new wiring. We have an LFP Model 3 so whenever it's home, it's plugged in. We don't drive 400KM's every day, so on the days we drive less, the charging catches up that evening and fills the battery. Unless you're consistently driving long distances every day using most of the battery, or you drive around all night instead of sleeping, then IMO you really don't need a level 2 charger.

Recently bought Tesla, when ever I had a question about Tesla and if i come to youtube and thats it there is a video related to it from you. These videos are much needed ones and quite handy. Great videos.

A clothes dryer pulls 10 amps… anyone ever worried about its power socket or the in home wiring ? I charge a model 3 standard range with a granny charger at home. Our sockets over here are rated 16amps @ 240v, the granny charger accepts 13 amps. Charges the car just fine over night. I guess it all depends on how far you drive your car per day. A nine hour charge gives me 27kwh which is about what’s between 30% and 80% charge (the sweet spot for its generation battery chemistry) good for about 170km. So yeah.. it all depends on how much you drive per day I guess..

I've only ever used the 'granny charger' on my 62kWh Leaf. I will use the Tesla 'granny charger' on my Tesla Y LFP battery when I take deliver end of December.

In the USA you can change that adapter from 120V to 240V and charge twice as fast with the same charger.

Ganny charger is fine for charging after general round town use. I charge from solar and only use grid power on longer trips. Havnt charged from the grid in a few months.. and i live in " the land of the long white cloud" so sunny areas like California would be plentiful for solar charging. Its almost too good to be true.

We have the Model Y long range in the US and use 120 volt charger with no problem. On average we only use about 20% of the battery per day so it always charges up by the next morning.

Having read a few comments I thought I’d add this info as a main comment as opposed to just replying to another’s comment. The Tesla granny charger has interchangeable ends! In the UK you can just pull/yank on the the UK 3pin plug chargers tail and it will come out. You can purchase other charging tails direct from Tesla to insert (think builders BLUE big round 3pin end). You can have an electrician fit a 32A commando socket (female) either on the side of your house, garage or any install point just like you could/would get a proper level 2 charger fitted. A commando socket fitted in the UK costs a fraction of a level2 charging box (probably less than £200). You can then use the Tesla granny charger with the 32A commando tail inserted and turn your slow 6 - 9 mph granny charger into the exact same speed as a fully fitted 32A charger (7.4KW) which should give circa 25 - 29 mph charge to the likes of a Tesla model 3. P.s a granny charger is called a granny charger because it is SLOW (like most granny’s driving along the road) not because you can use it at your granny’s house. Although, you can do that too!! 🤪 For those non-Tesla granny charger holders it can be worth getting hold of a Tesla granny charger for the use case above. I’m not aware of other granny chargers that have this capability as they usually have a hard wired 3pin plug end that is not interchangeable or can handle such wide variety of power (13A-32A). This way you can have an easy way to get 32A charging for ANY EV!! Well any EV that can take the type2 charging end (sorry to you CHADEMO users). I would not recommend granny/commando charging long long term though, there is more safety built in to a fully fitted type2 unit opposed to long term granny/commando charging. Enjoy!

Good topic for debate. Granny chargers do have their uses in my opinion. If I go to my relatives houses for the day, they don't have a charging unit and it's not worth me or them paying for one to be installed as it would only get used very infrequently. I'd usually be there 10 hours, so even being able to add 40-80 miles of range back into the car is better than having to pay for that at a public charger. The car is sat there so it might as well be charging.

Really great channel - nice to see some practical, real world EV content. I’m curious about one thing - with the Tesla charging at home, how easy is it to disconnect the charging plug? My home charger won’t be a Tesla unit and wondering if this will cause extra hassle?

I coped with a granny charger on my e-tron 55 with a 78kwh battery fine doing 70 mile round trips daily, took about 11 hours worth of charging overnight but it was doable - that's with a much bigger battery and a much lower mi/kwh (~2.0 winter, 2.6-2.8 summer)

I am using my stock Tesla charger with NEMA14-50connection Instold by licensed election. 35Amps 25 m/h Basicli talking full charge overnight time.

Hi folks, scroll down a bit and read Cosmosrays comprehensive comments. Basically in the UK you can get adapters for the Tesla 'granny' charger that then will plug into a 32 amp or 16 amp 'Commando' sockets - they are different sizes. Socket must by law be professionally installed but is much cheaper than a so called 'wall charger' - which is really a sophisticated connection unit - the 'charger' is actually in the car. A 32 amp Commando socket will give the same charge rate as a single phase UK wall unit. Wall unit is somewhat safer and gives more facilities buy can cost up to £900 to have installed depending on where it is placed - a Commando is just a couple of hundreds. 32 amps will charge three times faster than the maximum 10 amps that can be drawn from a UK 13 amp socket. On an Economy seven tariff one could get around 50 kilowatt hours of charge into your vehicle battery during the seven hours of overnight cheap tariff for a cost at the time of writing of under £4.50 - £0.09 per kilowatt hour. That would give a range of about 200 miles at 4 miles per kilowatt hour - or pro rata if more or less efficient. For long term use if possible I strongly suggest a full on wall connection unit - it will add value to your property and is a very sound investment. It is a bit safer and more convenient. I hope this is helpful to people thinking about getting an EV. Well done for considering it!

If I go away to friends over weekend and they think it's okay to charge at their house I use the granny charger. Most of the time car reports that I can pull 13 - 16 A from the house so I use to adjust it down to 8 - 9 A to not push the electric system too hard. If the care isn't used so much during that weekend the charging speed are more than enough to make my battery charged at the time for going back home. Even if I want to charge it to 100 % it would be enough juice in the charger to make the car fully loaded. So it has a meaning, but if I would have to buy it separately I don't know if I would do that. Here in Sweden we get the charger with the car on delivery.

Can I suggest rather than get an extension leads out, turn your car around.

Re water in connector; Long term you will have corrosion in the connector and it will generate heat and eventually fail needing a new cable and charge port!

Just an observation but you should probably look to get a charger holder for that type-2 charging cable to prevent water ingress rather than relaying on the rubber cover. It may well ultimately lead to significant issues with either the charging cable or worse still, the Tesla charging port. They are only £10-£15 on Amazon. Mine came with one and it's been dry as a bone since May.

Removing the charger is the same as removing the spare wheel. You won’t notice unless you need it, and then it’s a showstopper.

You are not understanding electrical power systems in US homes, while it is true that most outlets are 120 Volts, houses also have 240 volt outlets for washers and dryers that can be used to charge, and like you most people with a Tesla add dedicated 240 volts 48 amp line.

if you charge for 72 hours how much is that going to cost for electricity ?

Why not just back the car in to get the port closer

The granny charger should be an emergency thing and should only be used in an emergency so you would never charge it to full . Charge it just enough to get to a proper charger , or charge over night then go to a proper charger the next day.

Turning the car around not easier? 😂

VW will charge you £300 on top of the price of the car for a granny charger .

WHAT?? Rather than pull out an extension cord, you couldn't move your Model Y up ONE foot???? OR BACK your Model Y up instead of driving straight in??? REALLY!!

Funny 😂😂🤣🤣🤣🤣🤣🤣

Really what's the point owning a electric car.
