Battery Recharging Solutions

See the Jackery bar and Jackary mini on Amazon.

I set out on a hike this fall with a new myFC PowerTrekk Fuel Cell Charger to test. Sadly, I only had the opportunity to use it two times. My hike got cut short due to severe weather moving in (Tornadoes moved through the day after I bailed).

The PowerTrekk performed admirably and at 8.6oz it is just about what you are looking for. You will have to add a few of the fuel pucks, but they are rather small and lightweight.

With the limited experience I have with it in the field, I don't know that I would trust it quite yet for anything essential, but you could live without the iPad if it came down to it.

I decided to go with the PowerTrekk over a solar solution because it does not depend on sun exposure, and I could let it recharge my phone during the night.

You could check options by NewTrent. Not sure they will exactly match your specs, but I have one of their chargers and have been really happy with it.

iPad mini ~16,600 milliwatt-hours
iPad mini Retina ~23,800 milliwatt-hours

"iPad mini ~16,600 milliwatt-hours
iPad mini Retina ~23,800 milliwatt-hours"

and it looks like the ipad mini comes with the 5W charger while the ipad mini with retina takes the 12W charger..

If you have the reg mini most USB chargers should be fine(w/5W out) but if you have the retina you might find one with a 2.1A or 2.4A out

(maybe something like this)
