Why don't UPS' come with more Surge Protection?

[LongbowX404]

I was recently looking at getting a UPS for my computer (We had a power outage yesterday, that was annoying)

I noticed UPS don't typically come with alot of surge protection.

I had been looking at a 1500VA UPS with 865 Watts and I read that it only had a little more than 350 Joules of surge protection.

My current Surge Protector has 3020 Joules of protection.

What am I missing LTT? Why is there such a low amount of protection on a UPS like that?

HALP!

Its a Backup "Power Supply" not a Surge Protector

UPS's don't typically have a lot of surge protection because it's a battery backup system, even if your power doesn't go out and say it there is a large variation in voltages due to a thunderstorm it will kick in the battery backup to correct for an over or undervoltage situation. Many smart UPS's have a tolerance which you can change for when that occurs.
