Hello everyone. In case of an emergency, I bought an Anker Powercore portable charger for my phone. I'm not going to use it for day to day use, just for an emergency. Might anyone know the best way to maintain it? I'm thinking it's not good to keep it always plugged in, right? Should I use it to charge my phone once or week or on some other schedule? Thanks in advance for any advice.
