Same caffeine. You just stop paying for the can, the fridge and the truck that moved it.

Inside Watt

Seven things, and what each one is actually doing.

Caffeine 200 mg

The part that wakes you up. More than a 16oz can, about the same as two coffees. Enough to actually do something.

L-Theanine 200 mg

The reason this doesn't feel like a can. Matched one-to-one with the caffeine, so the energy comes up level instead of arriving all at once — and doesn't drop you at three. This is the part a can can't do.

Vitamin B12 100 mcg

The tiredness one. Helps your body turn what you eat into energy it can actually use, and supports your nervous system while it does it.

Vitamin C 90 mg

A full day's worth. Takes the edge off feeling run down, and helps with the same energy conversion job.

Niacin (B3) 20 mg

Works alongside B12 on the same task — releasing energy from food instead of leaving it sitting there.

Pantothenic acid 5 mg

Rounds out the set. Another one your body needs to get energy out of what you've eaten.

Vitamin B6 2 mg

Deliberately not mega-dosed. Enough to help with tiredness — not the 2,000% you see on some cans, which does nothing extra for you and isn't a great idea every day for years.

Everything else in the tablet is there for flavor, color, and to make it dissolve properly.

How to drink Watt

Three steps. No can, no fridge, no coffee queue.

1. Pick your flavor

Whichever one you're in the mood for. Original tastes like the can you already drink.

LIGHTMEDIUMSTRONG

2. Add water — as much as you want

One tablet, 12–16oz of cold water, about a minute to dissolve. Less water, stronger taste. Same caffeine either way — you're only choosing how concentrated it is.

3. Drink it

Stir or shake and go. Want half the caffeine? Snap the tablet on the score line and keep the other half in the tube.

Genuinely didn't expect this

Was on 2 white monsters a day for like 3 years. Ordered these mostly because of the price tbh. White citrus is the closest thing I've found to it — not identical, but close enough that I stopped buying cans. The big thing is I don't get that drop around 3pm anymore. Been 5 weeks.

Blue raspberry is dangerous

it's too good. i've had to stop myself doing three in a day. tastes like the blue slushie from a gas station but not sickly

Four stars, and here's why

Original and blue raspberry are excellent. White citrus is fine but a bit thin for me — I wanted more of a grapefruit bite and it's more of a lemon water. Not bad, just the one I reach for last. Everything else is exactly as described and the price is unreal compared to what I was spending.

The half thing sold me

200 is too much for me after about 2pm so I snap it and take half. Never been able to do that with a can. Small thing but it's the reason I'll keep buying these.

about the same taste, way less money

original tastes like red bull to me, maybe a bit less syrupy. not better. but it's 83 cents instead of 3.79 and it doesn't wreck me at 4pm so who cares

My gym bag thanks me

I used to carry two cans to the gym and they'd bang around and one time one opened in my bag. Now it's a tube in the side pocket. Mango lemonade is my favorite by a mile. Also my fridge shelf is free again which I didn't expect to care about.

Doesn't make my hands shake

I stopped drinking coffee because of the jitters and energy drinks were doing a milder version of the same thing. This doesn't. Same amount of caffeine on paper, feels completely different. Whatever the theanine is doing, it's doing it.

Takes a minute to dissolve, worth knowing

Good product. Only note is it takes closer to 90 seconds in properly cold water, not the 60 I expected, so don't try to rush it or you get grit at the bottom. Once you know that it's fine. Original is spot on.

Ordered again before the first tube ran out

That's the review really. Bought 3, on my second, already reordered.

Questions

Everything people ask before their first order. Can't find it? Use the contact form linked in the footer.

How much caffeine is in one?
200mg — more than a 16oz can, roughly two coffees. The tablet is scored, so if that's more than you want, snap it in half for 100mg.
Will it taste like a supplement?
No, and this is the thing we spent longest on. There's no sucralose in it — we use stevia Reb-M and monk fruit instead, which is why it doesn't have the chemical aftertaste most zero-sugar drinks leave.
How is this so much cheaper?
You're not paying to ship water. A can is 95% water, in aluminum, kept cold, moved by truck. We ship the 4.5 grams that do something and you add the water.
Is it actually the same as an energy drink?
Same caffeine, more than most. What's different is 200mg of L-theanine alongside it, which is what stops the spike-and-drop. A canned drink can't hold that much theanine on a shelf, which is why none of them do.
How many can I have a day?
Two at most. That's 400mg of caffeine, which is the FDA's daily ceiling for healthy adults — and it counts everything else you drink, so factor in your coffee.
What if I don't like it?
Contact us through the form linked in the footer within 30 days of delivery and we'll refund the order. Keep the tubes — sending them back costs us both more than it's worth.
When will my preorder ship?
WATT is a preorder and is not ready to ship. Shipping is still several weeks away; this is an estimate, not a confirmed date. Payment is collected at checkout. We will email updates and tracking when your order ships. Shipping is free with 2 or more tubes, otherwise $4.90.
Can I cancel or change a preorder?
Yes. Email hey@drinkwatt.com before shipment to cancel for a full refund, including shipping. For changes, contact us and we will confirm what is possible.
