Looking forward to warmer weather in the NE US and thinking about nice long bike rides. I am psyched to have such a cool little GPS/computer/map system and plan to take the Droid on long rides. Some will be 3+ hours and I don't want to worry about running out of juice. Researching it looks like I have a few options and wanted to know what you all think. Mostly I think the droid will just sit in my Jersey pocket with screen off but tracking GPS. Occasionally I will check maps. I figure my options are - 1- buy a spare battery - weight- not much, 1300 mAh - Downside, sometime during the ride I will need to swap batteries and restart GPS apps that I might be running. This would be really annoying so I think this is out as an option. 2- battery extender like Satechi iCel 4400 mAh Battery Extender. Pricey but would certainly give me enough ride time & gets excellent reviews 3 - Solio H1000 Universal Hybrid Charger Not as much power as the battery extender but I really like the idea of charging while I am out riding, although it seems to charge pretty slowly and needs direct sunlight. Even without serious sun it would probably provide enough of a charge for all but the longest rides. Gets "ok" reviews 4 - something else? I would love advice or thoughts on any of the above, maybe an occasional backpacking trip too. Thanks!
