Question: Earth point is a dummy, no point buying this product, I had to wire the earth point externally to the charger, this should have been specified in the product discretion.

Answer: Negative Review

Question: Works with the Thinkpad power brick. I prefer this to the regular adapters because I can put this on my laptop's power source before the trip and I never have to worry about misplacing/forgetting the dang power adapters. Plus it makes is much easier not having to figure out how to plug some power stack contraption and keep it from disconnecting in various outlets. And it is shorter in size than the regular US power cord with adapter, meaning it has a chance of fitting in more hotel room power outlets, which for some reason are always located behind some unmovable nightstand with about half an inch of space to spare for plugging in stuff.

Answer: Positive Review

Question: I opened the package, quickly installed the battery and was up and running on my laptop within a few minutes. A great value for the money!
