So, in my current day to day life it’s common that one battery is enough since they last probably 4 hours or something (highly dependent on use). If I’m going on a longer trip I might throw one or two batteries in my pocket. If I’m traveling on a plane or train, I take them all.
The chargers i am using were $10 amazon junk. Originally I had 3 chargers since I had 4 batteries, but more recently two of them broke and I just have 1 charger and 1 spare librem 5 that I am using as a charger, which is admittedly quite silly.
I had been thinking that maybe I would take the 2 broken chargers and frankenstein them together into 1 working charger but generally they were probably not designed to be user-disassembled and are just cheap junk. So a better charger might be smart. But they really work. I just put the battery in there and slide the little metal slider to connect to positive and negative, and it charges up the battery. It charges a little bit slower than the battery does inside of a Llibrem 5 but that’s probably OK and honestly might be good for safety, I don’t know.
