Zip-Linq power cable - power brick HOT

I just bought a V2000Z, which I'm very happy with. One of the reviews here complained that the power cord -- the cord from the outlet to the adapter -- was too bulky, and that you could replace it with a retractable cord from Zip-Linq for $9.00. I agreed, and bought exactly that cord. It has an adapter to turn the "figure 8" plug into a "Mickey Mouse" plug. It is much less bulky and makes the machine much more portable w/ power supply.

However, I'm convinced that with the thinner cord, the power brick itself seems much hotter. The cord is not hot, and neither plug is hot. Is that possible? Could it be the thinner cable? Or perhaps the adapter, which turns a three-prong cable into a two-prong. I guess that means it's not grounded. But I've never had a three-prong laptop cord anyway.

Any advice would be appreciated. I should probably stop using the Zip-Linq cable unless someone can assure me it's not dangerous.

 

No, there is corellation between Zip-Linq power cable and adapter getting hot. I have been using that Zip-Linq cable since last six months and have not seen any issue because of it. But recently the spring lock was not working properly in ziplink, so I just removed the cable from that spring housing and using cable directly without any problems.

As I mentioned in my review, it hardly takes 0.8 AMPS even at full load( typically when battery is charging and system has some load). So cable is not a problem, but Power bricks become quite warm when it is charging battery and also powering laptop at the same time. Nothing to do with Power card.
