Stay off the beaten track for longer with the external power pack. Designed specifically for Garmin's fitness and outdoor devices, this water-resistant power pack houses a 2200 mAh lithium-ion battery capable of recharging 5V devices while remaining robust, compact and lightweight enough for space and weight-conscious outdoor enthusiasts.

Suitable for even the most demanding riders, the external power pack provides real power when you need it most — the added 20 hours of extra ride time on the Edge® 800 makes the combination ideal for everything from week-long touring holidays to 24-hour marathon racers.

Recharge the pack 3 ways. Use the included folding solar panel, which allows the external power pack to be recharged to 1/3 power in 5 hours and full power within 15 hours. Use the universal mains charger, which is compatible in more than 150 countries. Or use the USB to recharge in less than 7 hours.
