As long as that product is functioning properly there is no issue with using it assuming the tips it has is the right polarity for the laptop.

The issue here is that the y700 uses a rectangular power plug, that adapter you linked does not have that type of connector, what are you connecting this to? As you can see the power plug is on the left, does not match anything the adapter you bought has.



You need this type of car adapter https://www.amazon.com/Charger-Thinkpad-Charger-Power-Cord-IdeaPad-Adapter/dp/B00G5LLT4E/ref=asc_df_B00G5LLT4E/?tag=hyprod-20&linkCode=df0&hvadid=309743296044&hvpos=&hvnetw=g&hvrand=3136884438490968183&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9001809&hvtargid=pla-570591110303&psc=1 It will charge it, with the laptop turned off.
