I didn’t know what a Gerber Omnivore was until I searched it based on your post.

Then I see Langcj’s comment in the below thread link about having a solar charger than could do all his Li-ions at once and that’s exactly what I’m driving at in this thread. Now in my case, I’m looking for foremost as lightweight as possible but with the Maglite I had in mind that goes out the window. Defensive-wise hell yes the Maglite fits the bill and to me being able to swing that sucker if necessary against the upcoming ubiquitous Zombies, well let’s just say it does have merit. So I’m trying to save weight but hey the Maglite is an elephant weight-wise no matter what I craft-up with a Li-ion capable solar charger. Looks like Scaru has the charger part nailed. Gotta research that unit out.
