Question: Where do I check if it is compatible with this charger? I have a sony Vaio E series 11'
Document: I just purchased this charger for my Sony vaio e series and it literally charged one time and stopped working. I am returning it and getting a refund. Don't waste your time or money!!! !
I got this to leave at an alternate living location to charge my Sony Vaio T series ultrabook. I don't have to remember to pack the power supply -- one less thing to remember
I guess I should have read the description with detail. But since the title suggested this was A SONY VAIO CHARGER I just bought the thing without reading this is actually just a compatible version, not the original vaio charger.Anyways.
This is exactly what I was needing, a second charger for my Sony Vaio. It isn't as long or as durable (seemingly) as the stock charger, but it gets the job done
I needed a new charger for my Sony Vaio, and options at Best Buy were $40-60. I couldn't believe the price of this one! It works well and seems sturdy. Also arrived within a day.
- Arrived when it said it would.- Product works.- Product was inexpensive- It IS the generic version, not Sony's charger, BUT it works with the Sony vaio, so I'm still all for it. I would repurchase. I just purchased this, though, so I can't remark on the longevity of it.
I purchased this power supply charger because I checked the web site for the device and found this replacement was nearly a 100% match.The price was right and the device charges the laptop without overheating.I would recommend this product as a replacement power supply charger for a Sony Vaio laptop.
This charger was no longer available through Sony. My nephew was very happy that the Seller could provide a replacement for his older Sony Vaio.
My daughter has a Sony Vaio laptop, and recently her charger caught on fire. Luckily she was right there when it happened, and was able to yank the plug out of the wall. Also luckily, her laptop wasn't injured.We decided to try this inexpensive charger instead of paying 5x the price for a Sony charger. It seems to work just like the original one (except for the smoke and flames), and we're pleased that we saved so much.
i was pleased to find this after my e series charger crapped out. well worth the price. cord is a little short, but thats a first world problem.
Answer: I too have a Sony Vaio, not sure of the series.  I suggest, looking at your adapter, if it is reads 90W 19.5V (mine did), it will work.
