looking at possibly purchasing one for my off-grid fur shed. I will be powering two shop lights and maybe a radio when i am skinning. Does anyone have any experience with these and know how long i could run two shop lights before recharging?

Hook it to a solar panel and never worry about it.

Had a Harbor freight solar setup on my camp building..came with the panels, battery and controller... ran 12v lights no problem, and was inexpensive at the time...

Use LED lights to lower amps used.

hi! couple days late to the thread, but wanted to add in-
I picked up a Jackery power pack last year, there are all kinds of cheaper knock offs, not really sure this was any better, but i was hoping for something that would last a few years,

look for the newer battery version it should say something PO4, they are supposed to last for like 10 years and 1000 recharges (will see)
there are all kinds of sizes, i went a little bigger than i thought i needed, have been happy with the power
if you have lights that are not super power suckers it would probably go weeks on a charge, I use it all over,
will run lights, tv, fans, small fridge, friends use it to power their cpaps
i see like everything the price is creeping up since i got mine
