One problem that I usually come across is the current ratings on mobile phone chargers. Right now, I need a 1A charger (which was shipped with my phone) and I have a 0.7A charger handy. Both the chargers have a 5V output.
I read here Charging devices - Voltage and Amperage that:
Correct voltage rating and too low current rating may cause damage. Slightly too low may be OK with computers an similar.
Now I am wondering:
1. What happens if I connect my phone to this charger ? Is it safe or will it cause problems later on?
I have a 220V / 50Hz / Single Phase supply.
Phone: Samsung Galaxy S3 (if this is even relevant) and the charger I have is from Samsung Galaxy S3 Mini
