By using a 240-volt circuit (such as the outlet for an electric dryer), the car might be able to receive 240 volts at 30 amps, or 6.6 kilowatt-hours per hour. This arrangement allows significantly faster charging, and can fully recharge the battery pack in four to five hours.
EXFat is just an extended version of the FAT format. Unlike FAT, and FAT32, it can support files as large as 16 Exbibytes, and can support disk sizes up to 64 Zebibytes. FAT32 only supports files as large as 4GBs, and drives as large as 2TBs.
Choose a format depending on what you plan on using your flash drive for. 1  Mac OS X Extended (Journaled) is the best format if you only plan on using your flash drive for OS X systems.  exFAT (FAT64) allows you to store files larger than 4 GB, and can be read and written in Windows and OS X 10.6.5 and later.
