TecMate OptiMate O-37 OBDII to SAE Charger Adapter

The OptiMate O-37 lets you maintain a car or pickup's battery through the OBDII port under the dash, without opening the hood. Plug it into the OBDII connector inside the cab, and connect a low current charger, a solar maintainer on the windshield, or an SAE battery monitor to the SAE end.

It's rated for up to 5 Amps of battery charging and maintenance and is protected with a 7.5 Amp fuse. OptiMate suggests it for its Solar 10W and 20W kits placed inside the windshield, or an OptiMate 2 connected to external AC power.
