Compared on paper

Every rating comes from the brand’s listing and is not a shop test (gathered 2 November 2026). Where a listing contradicts itself, both figures are shown.

How the points were given

Each tank is scored on performance, build, value, safety and warranty, with the weights published on our How We Pick page. Three of the five listings state a DOT safety certification, so those three score on safety and the other two score zero there, and two listings state no warranty term at all.

No score drops under 9.2 or climbs past 9.8; a tool’s place inside those bounds is set by its weighted point total.

What the listings tell you

Four of the five tanks hold about a pound of propane, while the fifth holds 5 pounds, so capacity alone splits this list into small cylinders and one larger growler. Only the refillable listings explain how refilling works, and two of them need a refill kit that is sold separately. Two listings state a warranty term, one states a manufacturer warranty with no term, and two state no warranty at all.

Buying guide: the best mini propane tank for your setup

Refillable or pre-filled

Refillable tanks, like the Flame King cylinders and the Mr. Heater Fuel Keg, can be filled again instead of thrown away, but the Flame King listings and the Mr. Heater listing both note that a refill kit is sold separately. The Evergreen cylinder comes pre-filled with 16 ounces of propane, so it is ready to use with no kit and no filling step. Pick refillable when the tank will see regular use, and pre-filled when it is a spare for an emergency kit.

Match the connection to the appliance

The Evergreen listing states a standard CGA 600 connection valve for portable propane appliances, including tabletop grills, camping stoves, lanterns and portable heaters. The Ignik listing states a hose that fits 1-inch 20UNEF connectors and 0.5-inch QCC1/OPD compatible products, including standard home BBQ grills. Check the connection on the appliance first, since a tank with the wrong fitting cannot be used even when the capacity is right.

Size and weight for carrying

The 1-pound cylinders weigh 1.0 pounds to 1.52 pounds empty and measure about 8 inches tall, so they pack easily in a camping kit or a garage shelf. The Ignik growler weighs 10.5 pounds empty and 15.5 pounds full, so it suits a base camp or a tailgate more than a backpack. For more heating options, see the best propane garage heater list.

Read the warranty term before buying

The Mr. Heater listing states a 1 Year Limited warranty, while the Flame King listings state a 30 Day warranty, and the Ignik listing states a manufacturer warranty with no term given. The Evergreen listing states no warranty term. A longer stated term is worth more when the tank will be refilled many times, since the valve and the cylinder see repeated use.

Garage Fit Check

• Measure the shelf or the storage spot: the 1-pound cylinders stand about 8 inches tall, while the Ignik growler measures 13.5 inches in its longest dimension.
• Check the connection on the appliance against the listing: CGA 600 on the Evergreen, 1-inch 20UNEF and 0.5-inch QCC1/OPD on the Ignik hose.
• Budget for a refill kit when buying a refillable tank: the Mr. Heater Fuel Keg requires a Fuel Keg Refill Kit, and the Flame King cylinders need a refill adapter or refill kit, all sold separately.
• Weigh the full tank, not just the empty one: the Ignik growler is 10.5 pounds empty and 15.5 pounds full.
• Never run a fuel heater or an unvented heater in a closed garage, and follow the maker ventilation guidance plus a CO alarm for fuel heaters.
