Several types of USB car chargers can work with many types of electronic equipment. A single-port charger is a small device with only a single USB connection. Multiple USB port chargers are larger and can simultaneously connect to multiple devices.
Most 12-volt DC/AC power inverters also support USB connections. These special inverters enable the connectivity of standard plugs into an automobile 12-volt power system. Most inverters include USB connections, which provide connectivity of standard computer electronic devices into the plug.
A solar-powered USB car charger is another example of a portable charging unit. These are typically more expensive then a standard power plug charger but can charge equipment without draining the battery of the automobile. The solar panels spread across the dashboard and are connected with a USB port. These units typically can charge multiple devices.
A multiple-port charger is more expensive than a single-unit charger. These chargers include multiple input ports. Having this type of USB car charger provides more flexibly for people who use multiple devices while on the road.
