solar charger capable charging 18650s

[Gr8Scott]

I just got back from being out in the bush for four days and I vape a sub-ohm (.52 Ω ). Lotta watts, (34 on a full 18650).

I only brought 5 batteries so pretty much continuously(from sunrise) I kept a single 18650 in an xtar MP1S connected to a Thunderbolt Magnum Solar Panel from Harbor Freight (5 watt). (http://www.harborfreight.com/5-watt-foldable-solar-panel-charger-60449.html).

I took most of the day, but it powered up an 18650 (drained down to 3.8v) up to 4.1-4.2v.

I am a heavy vaper, but I didn't run out of vape. Just kept rotating as long as the sun was in the sky.

So, it works and it works on the cheap.




XTAR MP1S: $10

Thunderbolt Panel: $35

Blowing Huge non-stop clouds while camping: Priceless

That's excellent news. I didn't think a 5 watt charger would be of much use, even if given all day long to recharge. Unfortunately, I use an APV and discharge a 2000mAh 18650 down to 3.2V every day before recharging and would need two days to charge a battery with your set-up.

Regarding the map on post #16, where were you located out in the bush? Just interested in how much solar energy you had available because it varies a lot in the US.
