This power supply was ordered to replace the original. It has the same voltage and current (19V/2.37A) as new. It doesn't get hot like other reviews have claimed, and the tip that comes with the R11 Chromebook snaps in just like the original. The only difference I noticed was that the original power adapter has a grounded (3-pin) plug while the non-original power adapter doesn't. But if you think about it, then this grounding is just from the wall to the box (inverter). There are only 2 wires (+,-) from the small power adapter to the laptop connector, not 3. But apart from that there is one color, the original is white and this one is black, both are made in China. The same thing.
