How do I know if my charger is fast?

Take your mobile charger now and look at the power output ratings; if you see 5V—1A or like this 5V—1000mA or anything less than that 1000mAh, you immediately know you’ve got a slow phone charger. But if you see 5V—2A, or 5V—2000mA or more in this format, then congratulation you’ve got a quick phone charger.

Is Slower charging better for battery?

Slower charging actually is better because there is less internal heat build-up. Temperature extremes, whether hot or cold, are never good for a battery. So if you charge a battery a thousand times slowly as opposed to a thousand “fast charges”, the former will have a longer life, all other things being equal.
