GrowlerWerksStainless Steel Nitro Chargers (package of 5), 16g, Silver

I use these as well as another brand for go kart and minibike racing engines. I built my own nitrous oxide setup and these work great for it. Spendy? Yes! But fun isn’t cheap. With the jet I made for spraying, it gives the built predator 212 engine a big bump in power!

For this brands cold brew keg. Good stuff.

I bought these for my son to go along with his growler, works coffee maker and they work great. I did accidentally buy the wrong ones at first and the customer service was excellent from this company in sending me the right type.

Doing the math it’s a bit more expensive than using a 1 pint whipped cream dispenser but not by much, but both are miles cheaper than buying nitro coffee retail. I’ve gone through about 50 of these cartridges and no problems so far. I can’t find this large 16g size cartridge anywhere else for a better deal yet, but GrolwerWork’s website talks about a converter you can get to accommodate the 8g size for foreign use, for free, but it would take multiple charges (I use 8g per pint in whipped cream dispenser so I would think 2 - 8g chargers per keg (about 66oz when filled to brim). Plus untwisting and recharging with multiple n2os in the growler would let out any undiluted n2o, which takes a few days to substantially dilute fyi and the n2o lets out more air as the growler gets less full unless you turn it off, so it thus at least some waste of money.

Used it to successfully brew Nitro Coffee (cold) with a uKeg 64 oz growler.

Really good deal. If you check around on Amazon there are a ton of different options for nitro but most of them are 8 gram or smaller carts. There are many that are a measly 2 grams per cart which will barely work for what you want these for. What you want is 16 grams to make sure your 64 ounces of coffee is fully nitro infused and creamy.The chargers in this listing are 16 grams per cart and work wonderfully in the uKeg Nitro for cold brew coffee. I did not get any weird tastes or anything like that. Just great nitro coffee.

The product lasts about 1 week each. Works great!!!

Got these and the nitro coffee keg for my wife that is working remotely and doesn't have access any other way to get it. She was very surprised and happy to get it
