Note 2 Charger

[ejeeks9]

The OEM chargers for my Note2 is around 2amps. I have a few questions:
1. Is it ok to leave my note2 charging overnight with this OEM charger?
2. I have a Galaxy W charger rated at 0.7amps. Is it ok to use it to charge my Note2? Yes, I am aware that is would be charging at a slower rate.
3. if i buy those 'alternative' chargers, should i also go for the same 2amp rating?

Overnight on the charger is no problem. The phone will automatically disable charging after 100% to prevent overcharging.

Lower amp chargers are fine. They will just charge slower.

2 amp aftermarket chargers should work fine as well.
