What's the best way to charge?

[Back Pack Hack]

I'm going out on a limb here, but there has to be some kinda "hand crank" that charge a battery? ...

I tried one of those K-tor things. Had a heart attack cranking for 15 minutes..... and never gained one percent on the battery.

...Also, there are ways to convert 9V batteries to charge a cellphone, its slow, but better than a dead battery.

Hey Deebo, nice to see you. I researched the 'hand crank' options out there, to keep a radio charged up, seemed to be an hour of cranking for 15 min of use. Phones pull less so that might be doable. I'll check out the 9V conversion idea. Thanks!

If'n you're handy with small electronics projects and soldering:

Git yessef some TEC1-12706 thermoelectric peltier podules and one or two L7805 voltage regulators. The former will produce electricity from heat (like a fire), the latter will regulate it to 5VDC. Splice in a USB cord and you're charging devices off your woodburner.
...
You can buy 10 peltier modules and 20 regulators online for less than $25, so you can make several chargers.

Might be the way to go would be to use your device to slow-charge up a battery pack, it could sit on the stove all day/night long, and then charge the phone off the pack. Would have to shield the pack from the heat... it could sit off the stove to the side... Thoughts?

I've seen it done, and I have the parts to build one to try it out. I just haven't had time to put it all together and test it out. When I do, I'll post a video.

In the meantime, here's the voltage regulator hooked up to my power supply to show how it works:

Brunton makes several sizes of roll up solar panels to charge batteries. I have one for when I'm hunting in the boonies to charge my phone. It works great. I've had mine for years, I hope they still make them.

Googled. They do.
Thanks!

Seen a video of a guy who mounted a bicycle stationary and welded the chain cog somehow to an old chevy alternator. Used it like an exercise bike for an hour or so and charged up a car battery. He then used an inverter to power his appliances etc.... sorry i dont know all the details but a google should get you some blueprints if you are interested

I decided on this charger to try, it and a couple of the batteries, they came in last week, glad I got them up here cause the main batts will now be pretty much only for pumping water.



You'll know if they work - since the phone is my only access online after today.
Thanks again guys for all your input!

I have a similar get up with a couple GoalZero panels and a couple portable chargers.
