X1 Carbon type 20A7 - Can I use the power adapter from my former W530?

2017-01-15, 0:57 AM

Hi all, 

I happen to have a spare power adapter from my former W530. Can I use it with my X1 Carbon 20A7? Connector is the same but of course the W530 one is much more powerful, so I guess the question is: is the X1 protected against more Amperes than expected?

 

Thanks and regards

Welcome to the forum.

 

Each ThinkPad draws as much current as it needs so in principle an AC charger with a higher Amperage rating will work just fine. If anything it will be able to recharge the battery a bit faster.

 

However, according to ThinkWiki Power Connector the W530 uses a special variant of the round "barrel" plug that is designed for use only with W520/W530 ThinkPads. 

 

The X1C2-20A7 uses the newer rectangular plug. If you want to use the charger from a W530 with the X1 then you would normally need an adapter like this:

But because the W520/W530 uses a variant of the standard round plug, you would need to either find such an adapter that is designed for this variant or make a modification to the charger plug as mentioned in the ThinkWiki article.
