thanks,
base2 - I've got a quill stem. '89 Panasonic Mountain Kat. Hence the 26in wheel mentioned.
I've seen the sign wave. co-signer wave. irrelevant tangent wave. I mean sinewave - I was hoping to find something cheaper (i really like that German one with the switch, that's pretty sweet...). which lead to
unterhausen 's comments: yes, quite. The hub. the lights. Now an inverter....
I've got a couple of long tours coming up, a 4~5 day trek, and a 7 ~ 8 day trek. I've had a little 10Ah pack last 5 days riding the GAP/ C&O. I used it only for my iPhone. We only had to use lights a small bit of the whole trip. I've wanted to get away from having to keep lights charged, and thinking about the battery pack, and do I need to plug in my phone during lunch.... and all that stuff. I just charge up while riding - hopefully with no worries.
I don't use a Garmin (that's mo' money!), I just use my phone GPS.
thanks, y'all. hopefully an EE or that guy from ElectroBOOM on YouTube will post a reply.
