    I got a new drill from amazon.de (good value BTW, even after shipping) & it came with a 2 pin plug for the charger. Is it okay to cut the 2 pin off & replace with a 3 pin?

    I've read before that from a safety aspect you're better off using an adapter rather than rewiring.



  • Registered Users, Registered Users 2 Posts: 7,771 ✭✭✭Bluefoam


    In fairness, yeh... I've got one in the amazon basket.

    For low current devices it's sufficient to use a converter, but for anything beyond about 3A I'd be rewiring it to a BS standard plug, especially if it's being used outdoors.

    I have a few adapters similar to this

    Just one screw to undo and once the 2 pin plug is in and the unit is closed back up the 2 pin plug is captive and can't be pulled back out. Job done. Also fused.

    Wake me up when it's all over.

    I can't remember exactly what I was looking to rewire, but safety was the reason given not to on some UK forum.

    Would changing the plug affect the warranty?



  • Moderators, Category Moderators, Arts Moderators, Sports Moderators, Paid Member Posts: 56,402 CMod ✭✭✭✭magicbastarder


    i guess if you botched the job, it could be less safe. harder to get it wrong with one of those adapters.



  • Registered Users, Registered Users 2 Posts: 30,532 ✭✭✭✭Lumen


    I believe that non-rewirable (moulded) plugs are designed as such in order that the plug isn't reused, rather than the cable. The reason being that a moulded plug can have a plastic earth pin if the device is designed without need for an earth - reusing that plug on an earthed device would be dangerous, so the plug is moulded on to prevent reuse.

    That's my theory anyway.



  • Registered Users, Registered Users 2 Posts: 19,164 ✭✭✭✭Del2005


    That's no good for here as its 120V only not 120V- 240V. You'll need a voltage dropper.

    The adapter plug posted where banned in my company on safety grounds. A properly wired plug with the correctly rated fuse is always the safest.



  • Registered Users, Registered Users 2 Posts: 10,333 ✭✭✭✭The Continental Op


    Why or are you jumping to conclusions?

    Firstly despite the OP's link its not a link to their purchase on Amazon.de. Secondly Germany afaik uses 220-240V so good chance that is what the OP bought. Then if what the OP bought really was "good value BTW, even after shipping" it could have been a chinese knock off and they all seem to be dual voltage.

    Just to be sure the OP needs to turn the charger over and check to see if the rating plate states 240 Volts on it. As a small note of caution the 120V version of the DC18RC states its 240W, thats Watts and not voltage so might be mixed up with 240V? It should say something like 240V ~ 50-60Hz.

    Wake me up when it's all over.

    when the OP mentioned a 2-pin plug i would assume they meant european 2-pin rather than american 2-pin.



  • Registered Users, Registered Users 2, Paid Member Posts: 10,144 ✭✭✭✭10-10-20


    If it's one of these "two pin plugs", then you definitely do not be using it with a Dublin airport converter job.

    If I'm reading it correctly the OP has bought a cordless drill, it's the plug on the charger he wants to change to a standard 3 pin plug, so no issues with using it outdoors.



  • Registered Users, Registered Users 2 Posts: 1,793 ✭✭✭monseiur


    You're overthinking it OP, just snip off 2 pin plug and fit a standard 3 pin - Job done



  • Registered Users, Registered Users 2 Posts: 19,164 ✭✭✭✭Del2005



    The OPs link is to https://www.makitatools.com/products/details/DC18RC and the data sheet from that link has 120V as the input voltage. Just because they used the German site doesn't mean it can't have been bought from a supplier in the USA, every Amazon site charges Irish VAT/duties if the item will ship here, I've often seen items on sale on UK or other European sites shipping from China and other countries.



  • Registered Users, Registered Users 2 Posts: 6,329 ✭✭✭greasepalm


    I reread the specs and it does say its 120v and do not use it but send it back as its not 240v.





  • Registered Users, Registered Users 2 Posts: 2,239 ✭✭✭Explosive_Cornflake


    Just chop off the plug and throw a 3 pin on there.

    Or do what I'd do stick a screwdriver in the earth socket and jam the plug in anyway

    Thanks everyone for the comments, I think you're all a bit more animated about it than I am.

    ... so, I did contact amazon cheekily to see if they'd send the adapter. They said no & emailed me a return lable. I told them I was very happy with the purchase and didn't want to return it & that i'd just buy an adapter on amazon :)

    then... they said don't be silly, we'll send you a full refund for the drill set including shipping for the trouble and you can keep the product... Happy days. I've got a plug on the way and a new drill & set of batteries.

    No, it's a DC18RC, but I just picked that link up off the internet... It's the exact same spec as my other battery charger which does in fact have a 3 pin plug on it...



  • Registered Users, Registered Users 2 Posts: 6,329 ✭✭✭greasepalm


    Double check the sticker on unit says 220-240v then your okay .

    Once the charger says 240v we be happy and you be alive another day.

    I have a laptop here with a strange plug going into an adapter 13 amp plug and does not bother me as its in a fixed position.

    Its really annoying DeWalt do exactly the same thing. They'll have a charger for say the US that only runs at 120V and one for the UK that runs on 240V and other for Germany that runs on 240V but all with different plugs. Yet they all have the same model number.

    Why they don't use a switched power supply that runs on 100V all the way up to 240V like most laptop power supplies I don't know? Must be cheaper to do it the way they do? If you check youtube you'll see its often only a matter of changing two components to make a 120V charger 240V compatible.

    One of the easiest ways of checking if you have a chinese knock off charger (DeWalt/Makita) is that it will be dual voltage and take 120V or 240V if the chinese knock off merchants can do that why can't the OEM's?

    Wake me up when it's all over.



  • Registered Users, Registered Users 2 Posts: 7,771 ✭✭✭Bluefoam


    Just checked, it's 220-240v



  • Registered Users, Registered Users 2, Paid Member Posts: 10,144 ✭✭✭✭10-10-20


    I still think you need to chop off the cable and give us a bit of return for our over-enthusiastic efforts. Live-stream it. 😜



  • Moderators, Category Moderators, Arts Moderators, Sports Moderators, Paid Member Posts: 56,402 CMod ✭✭✭✭magicbastarder


    You'll get a better idea of what voltage it's dealing with it you lick the bare cables.



  • Registered Users, Registered Users 2, Paid Member Posts: 10,144 ✭✭✭✭10-10-20


    There has never been a situation where a bit of salt hasn't improved the cable-licking experience, especially on AC mains. Pepper; not so much.
