Designed to be charged by your existing NAVAir power harness, these units connect in-line and feed your XM WX receiver with clean, continuous battery power. You can now start your weather system prior to engine start without concerns for XM WX connectivity problems, and know that if you ever suffer an in-flight power failure, your NAVAir PDA or EFB will continue to receive XM WX data without interruption until you can land safely. Additionally you can now use the battery to power your XM WX receiver on the ground in order to get preflight weather information, and prepare your routes at home. in your hotel, office or in the FBO.

All NAVAir Battery Backup solutions come with a power switch to save battery power when not in use, a set of Green and Red LEDs with a test switch to show you remaining power and sophisticated charging and battery protection circuits to ensure clean, reliable power and long battery life. We offer two compact, low profile models designed for easy cockpit placement, portability and carrying ease.

When plugged in to airplane power in flight, NAVAir battery packs continuously charge and power your weather receivers. A fully drained battery pack will start charging and powering your XM WX receiver as soon as external power is applied, and will reach full capacity in 2 - 4 hours. Faster charging times are possible if the battery pack is not powering your receiver at the same time.
