Super Lithium Power Cell

I have a small lithium emergency charger for my cell phone. I carry it in a small pouch with a bunch of assorted charging cables… It does a decent job in an emergency for my phone. I can add 60-70% charge before it gives out. Perfect to make sure I get picked up from the bus stop after work. I tried running a raspberry pi but it only lasted a couple of hours. I needed something bigger.”
