A 9.6 fl oz can of Starbucks Nitro Cold Brew Black Unsweetened holds 155 mg of caffeine, and the Splash of Sweet Cream version in the same can drops to 110 mg. The larger 11 oz Black can runs 235 mg. So one small can is not the same drink as the cafe pour: a grande Nitro at the counter is 280 mg. PepsiCo, which produces the cans, lists 155 mg for the Black Unsweet 9.6 oz and 110 mg for the Splash of Sweet Cream, and Caffeine Informer lists 235 mg for the 11 oz Black can.
Why the can is weaker than the cafe pour
People assume the can and the cup are the same coffee in different packaging. They are not, and the reason is volume plus formulation. The most common single-serve can, the 9.6 oz Black Unsweet, is a small can. At 155 mg it lands a little above half of a grande Nitro poured in store. If your mental anchor is the cafe drink, the can will feel light, and it is: you are drinking 9.6 ounces, not 16.
Concentration tells the fuller story. The 9.6 oz Black can works out to about 16 mg of caffeine per fluid ounce. The cafe Nitro, whether tall or grande, sits around 18 mg per ounce because it is served straight with no ice. So the can is a touch less dense than the pour and a lot smaller, which is why a single can does not hit like the counter drink. The 11 oz Black can is the exception. It is built stronger, roughly 21 mg per ounce, so at 235 mg it comes close to a grande in a smaller package. Read the can size before you decide how wired you should feel.
The Splash of Sweet Cream can is the one that surprises people in the other direction. At 110 mg in the same 9.6 oz can, it carries about a third less caffeine than the Black Unsweet because the cream cuts the coffee. If you grab the sweet cream version expecting a black-coffee jolt, you are closer to a single cup of drip than to a cold brew.

Sources: PepsiCo Product Facts for the Black Unsweet 9.6 oz (155 mg) and Splash of Sweet Cream 9.6 oz (110 mg); Caffeine Informer for the 11 oz Black can (235 mg); Caffeine Informer and Starbucks.com for the cafe pour (215 mg tall, 280 mg grande). Per-ounce figures are rounded. The cafe Nitro is served without ice, which is why its per-ounce number stays high across sizes.
For context, the FDA cites 400mg of caffeine a day as an amount generally not associated with negative effects in healthy adults. How caffeine affects you depends on your own tolerance and health, so treat these numbers as information, not advice.
Practical read for a shift: two 9.6 oz Black cans put you at 310 mg, comfortably under the FDA context line. Swap to the 11 oz Black cans and two of them hit 470 mg, past it. Two grande pours from the counter land at 560 mg, so the cafe drink is the one that stacks up fast. The sweet cream cans are the gentlest of the group at 110 mg each. As always, the label on the can you actually grabbed matters more than the brand on the front.
