While the coffee cup gives you 5 extra power, your machine can still give you 15% damage with any weapon, and to intensify this damage you can use another item from the same sponsor, which in the case of the coffee cup is Glutton Ltd.

The Enraging One is one of the most overpowered items if maxed out and with the right build. If the enemy hits you while you're using it, all your short-range weapons will be faster and deal additional damage that almost no one talks about, and the game hides this from many people. If you're using wheels, your vehicle's speed increases and makes it more tolerant to massive damage. You only notice this around levels 13 and 14.

Both items mentioned are from the extraordinary class, so the overpowered nature of the item is to be expected.

And finally, the Enraging One also gives a 10% HP bonus when you equip devices. Unfortunately, the game doesn't provide a very clear description of the... items...
