If you own a Toshiba laptop, you need a Toshiba laptop charger. Laptops run on low voltage direct current, but the mains provide high voltage alternating current. Your charger converts that high voltage mains electricity into power your laptop can use.
While all new laptops come with a charger, if you buy a second-hand Satellite, you may need to pick up a new Toshiba laptop charger. Whether you want a backup charger for the office, or to replace one you cannot find, eBay has chargers for every Toshiba laptop from Satellites to Equiums.
Your laptop lives on electric power so take charge of its destiny and keep the electricity flowing.
