5. Powerlet Socket Kit, $49

Powerlet Socket Kit

In a similar vein to our recommendation of a battery charger, adding a Powelet socket (or two) to your bike gives you a clean, factory-appearing power supply on your bike. Having a Powerlet near your seat is a great way to charge you battery during the off season or get the juice to your electric vest. For any accessories you have mounted on your handlebar or dash, a switched Powerlet can keep your navigational tools from killing your battery when you stop for lunch. You can choose among the many model-specific Powerlet sockets or build your own from the Powerlet website. Powerlet also offers low-profile sockets and plugs and variety of adapter styles to fit almost any connector you may need.
