Charging

[David W Pratt]

My dynamo hub will charge a couple of AA batteries which can replenish the GPS.  My phone, however, won't charge below about 11mph. It beeps plaintively below that speed.  Does any one have experience with charging a power pack to then charge the phone?
Thanks in advance

That is the only way I do.  I charge the powerbank directly from the hub and use the powerbank to charge the batteries, phone, etc. 

Best, John

What power bank do you recommend?

[John Nettles]

Most anything from Anker is good.  I would get at least a 10k mAh one.  It boils down to how many charges you want to get from it (add up ALL your electrical needs), how heavy you are willing to carry, and how much you are willing to pay.

Be sure to get one with at least one 2 amp output.  The newer phones require a Type C port and up to a 3 amp so that should be beneficial to have also.  If you have a laptop, Kindle, or tablet, a larger sized model may be nice also.

I have an older 12k model and with my hub generator, I have never been totally out of power.  I do use campgrounds when available and hotels occasionally and recharge the power bank via regular AC outlet when reasonably possible, i.e. eating at a restaurant.  I don't prefer stealth camping but do it when I need to or in the forest.  Per day on average, I use 2-3 AA 2500mah rechargeable batteries for the GPS; about 25% of phone battery (Google 6P), and a NiteRider 750 light (usually needs to be fully recharged each day), and an occasional AAA battery.

My touring mainly consists of paved touring (80%) and 20% off-pavement (forest typically) touring.  However, I am rarely more than 2.5 days away from an AC outlet.

Hope this helps.  John
