#12 volt charger for macbook air portable

Replacing laptop batteries with Extra cell batteries available in the market can help. Powerbanks on the other hand have only usb 2 output interface. Most laptops charges through its adapter only.

These are not marketed by laptop manufacturers so I am not sure what your laptop warranty status will be if you purchase one of these banks and use it charge your laptop. I have seen one on ebay india, and the ad says that theyвЂ™ve even sold 29 units. There are power banks available with various plug in connectors for laptops, but they cost around 15,000.
