IEEE 1394 FireWire Adapters are a common requirement for mobile devices such as digital cameras, smartphones and external hard drives. FireWire 400 connections can achieve speeds up to 400Mbps, while FireWire 800 connections can achieve speeds up to 800Mbps. FireWire connections with four or six pins meet the FireWire 400 standard and connections with nine pins meet the FireWire 800 standard. These tiny adapters you have here will save you from having to buy a cable to go between your device and your computer, making life just that much simpler. Plus, with their molded construction, you can rest assured that these little adapters are durable and ready to get to work.
