Review on 19V 3.42A 65W AC Power Adapter Charger for Acer Chromebook 11 13 14 15 R11 CB3-131-C3SZ C720-2103 CB5-571-C1DZ CB3-111-C670 CB5-132T-C1LK C730E-C4BA; Aspire One Cloudbook 11 14 AO1-131-C7DW C9PM by Jerome Godwin

The tip of the power adapter is longer than the original Acer branded Chromebook. (See attached photo). This company buys their cables in China - that's what it says on the bag. I don't think this seller bothers to check the cables they ship. This longer tip is unstable, shaky, the cable is light, charges very, very slowly, but makes your laptop's cursor/pointer respond incorrectly, slow and like it's skipping and clicking on various links. Very frustrating! They offered to send me a replacement power supply cord, it arrived today and is still having the same issues. Both power supply cables end up in the garbage can. DON'T SPEND YOUR MONEY!
