Global recharge...does it stack?

The very rare purple IO sets all boast a 10% global recharge to all powers.

So, without hasten, an unslotted power that recharges in 100 seconds, will now recharge 10% faster, in 90 seconds. That much I get. (10% of 100 =10; 100-10=90)

Suppose I have two very rare purple IO sets - this same unslotted power that recharges now in 90 seconds, with the second set, does it now recharge in 81 seconds, or 80 seconds?

Or none of the above?

I realize that this 1 second difference is meaningless, I only use that time to make the math easy. I'm thinking about the longer recharge time powers, like blizzard.


Oh, one more question - is there a cap on recharge reduction?

See the article on paragonwiki.

The formula is:
RechargeTime = BaseRechargeTime / ( 100% + Buffs - Debuffs )

So filling in the blanks...
RechargeTime = 100 / 100% + 10 - 0)
90.909 = 100 / 100% + 10 - 0)

With 2 +10%s...
RechargeTime = 100 / 100% + 20 - 0)
83.333 = 100 / 100% + 20 - 0)

There's also a cap of 500% (or +400%) recharge.

Yes, the global recharge amounts stack, but Recharge does not act in a straight line . . . as you get more and more Recharge, it does less and less. I'm sure someone can post the formula used. (Edit: whoops, somebody did)

Stacking Global Recharge is key to making a "Perma-PA" Illusion/Radiation controller, or many of the other best builds in the game. Hasten gives about 70% recharge when active. Accelerate Metabolism in the Radiation Emission power set gives 30%.

(Not all the purple sets have that lovely 10% Recharge.

Its additive not multiplicative. However, 100% recharge bonus only halves the recharge time of a power rather than reducing it to 0 seconds so the math isn't exactly as you're suggesting.

I believe the formula is power recharge/(100+recharge bonus/100)

So adding 10% recharge bonus means a 100 second recharge would recharge

100/(1.1) = 90.9 seconds

Adding 50% recharge bonus means

100/(1.5) = 66.7 seconds

Adding 100% recharge bonus means

100/(2) = 50 seconds

Adding 200% recharge bonus means

100/(3) = 33.3 seconds

So you can see there is a pretty quick law of diminishing returns as you raise recharge....and yet its still one of the most powerful means of increasing all your powers at once.

You might want to take a look at Mid's Hero Designer for planning out and experimenting with builds.

Also since I don't believe anyone has mentioned it Global Recharge and Power specific recharge enhancements are added together in the formula Kitsune gave above.
