Solar packs are great for light‑weather runs, but a long raid usually means 6‑8 hours of zero sun and a lot of power drain from weapons, mods, and sensors. If the pack’s capacity is enough to run all your gear at an average of, say, 20 watts for 48 hours, then it’ll last—but only if you don’t use any high‑power items like drones or heavy weapons. Bring a backup battery or a portable charger anyway, and keep the solar panel clean; no one wants a half‑empty pack mid‑fight.

Sounds solid—just remember, a quick‑charge unit will still be a bottleneck if you’re firing a rifle or using a power‑intensive drone, so keep that in your loadout and treat the charger like a spare hand‑cannon: useful when you’ve got the right timing, but never the main tool. Keep the panel clean and test that regen rate; you’ll be laughing at the zombies when your power stays intact.

Nice, just be sure the regen curve actually covers the spikes from the combat cycle—if it drops below 20 watts in a burst, you’ll be on the brink before the raid even starts. Keep the panel spot‑clean, keep the pack’s capacity in mind, and you’ll be the last one standing when the undead swarm.
