iPad Wall Charger

[ahdickter]

Is it ok if I charge my iPhone 4S with an iPad 2 wall charger? Are there any downsides? If they're going to have 2 different chargers then there must be a reason.

The iPad requires more power for charging hence the different charger.

Yes, there are two different chargers because the iPad has a higher charging demand. Either will work, the iPhone charger would just be painfully slow to charge the iPad. The iPad charger will charge the phone just fine.

But then why not sell one charger for both iPhone/iPad if they both work with the higher-powered wall charger?

The iPad charger has 2.1A and the iPhone just 1A.

+ A = less charging time

The iPad needs more "A" because of it's bigger battery.

If you charge your 4S with the iPad charger it will charge faster, but I would not do that. I think the iPhone comes with 1A charger for a reason.

Because the iPad charger is larger, would require a bigger box and packaging, draws more energy than the iPhone charger, and probably costs more to make.

As stated above, the iPhone will only draw what it needs. The iPhone comes with a 1A charger because it's all that it needs. That doesn't mean that you can't use the iPad charger.
