Was /out/ at local State Park this past weekend. Comfy in tent watching some Netflix on my phone. Was right in the middle of that Sofia Vegara/Reese Witherspoon movie (Hot Pursuit) when my battery went critical. I carry a 3000mAh battery for charging my phone. Unfortunately I found out it can not power and charge phone at same time (only .5A i guess). My phone died and I could finish the movie. How do you sc/out/s charge your electronics? Is there a better option than a power bank? I could have paid $10 extra for a campsite with electricity but I thoight $25 was already pushing it for a campsite.
