ONLYFIRE Tabletop Gas Grill 3 Burners, Portable Propane BBQ with Foldable Legs, 24000BTU (GS307) Review (2026)

Overview of the grill

The ONLYFIRE GS307 is a tabletop propane grill with three separate burners producing a combined 24,000 BTUs, built with a stainless steel body and a stainless steel cooking grate. It folds down with locking legs and a locking lid for transport, and it includes a carry handle so it can move from a storage bay to a picnic table without extra hardware. Unlike stand-up grills that need their own legs and floor space, this style sets on top of an existing table or RV side table, which keeps its footprint smaller than a full stand-up unit while still offering more cooking control than a single-burner model.

Three burners and heat zones

Each of the three burners can be adjusted independently, which is the main advantage of this grill over simpler single or two-burner tabletop models. That setup allows a hotter zone for searing meat on one side while keeping a cooler zone on the other side for vegetables or food that just needs to stay warm, all without adjusting a single shared flame. The 24,000 BTU combined output is on the stronger side for a tabletop grill, giving it enough heat to sear well even in cooler outdoor conditions. The grate is listed at roughly 22 by 13 inches of stainless steel cooking surface, which is a reasonable size for cooking for a small group at a campsite.

Fuel flexibility and setup

The grill is built to run on either a small 1 pound propane cylinder or a standard 20 pound propane tank using the included hose, which gives some flexibility depending on whether you are grilling for a quick meal or a longer cookout. A removable grease tray sits under the cooking area to catch drippings, making cleanup more contained than grills without a dedicated tray. Setup involves unfolding the legs and locking them into place, then connecting the propane source, which is a fairly quick process compared to assembling a stand-up grill from a packed state, though it still takes a bit more handling than simply lighting a single-burner unit.

Size and propane use trade-offs

Running three burners instead of one naturally uses more propane per cookout, which matters for RVers trying to stretch a small cylinder across a multi-day trip rather than swapping tanks frequently. The grill is also larger than compact single-burner tabletop grills once unfolded, and while it locks flat for storage, it still needs more cabinet or storage bay space than the smallest camping grills on the market. Buyers choosing between this and a smaller grill should weigh whether the extra cooking control and surface area from three burners is worth the added propane consumption and storage footprint for their typical group size.

Who should buy it

This grill suits RV owners and campers who regularly cook for more than one or two people and want the flexibility of multiple heat zones on a single tabletop unit, without stepping up to a full stand-up grill. It is a strong match for anyone who already has a table or flat surface at their campsite to set it on. Solo travelers or anyone prioritizing minimal propane use and the smallest possible storage footprint may be better served by a single-burner tabletop grill, since the extra burners here are built for cooking flexibility and capacity rather than compact simplicity.
