Who it fits
Good fit for
You should consider this griddle if you need a portable cooking surface for tailgating, camping, or RV trips. The 18 x 14 inch iron plate handles multiple items at once, while the dual burners let you manage heat zones efficiently. The inclusion of hoses for both small and large propane tanks adds versatility. If you value a durable stainless steel build that fits easily into a car or storage space, this tabletop unit meets those practical needs without requiring permanent installation.
Who should skip it
Skip this model if you require a high-temperature searing surface for steaks. The 16,000 BTU output is moderate for a 252 square inch area, meaning it may struggle to maintain high heat during heavy loads. If you prefer electric convenience or indoor use, the propane requirement limits your options. Additionally, the iron surface requires seasoning to prevent rust, which adds maintenance time. Those seeking a non-stick coating or digital temperature controls will find this traditional flat-top design lacking in those specific features.
Verdict: The Onlyfire GS318 offers a durable, portable cooking experience with versatile fuel options. Its spec sheet highlights a balance of portability and cooking capacity for outdoor enthusiasts.
Key specs explained for this griddle
Total Heat Output: 16,000 BTU
This rating indicates the combined power of both burners. It allows you to sear steaks or cook large batches of pancakes quickly. Higher BTU means faster heating times compared to lower-output models. You can adjust each burner individually, letting you cook different foods at different temperatures simultaneously without wasting energy.
Cooking Area: 252 sq. in.
The flat iron surface measures 18 by 14 inches. This space fits multiple burgers, eggs, or vegetables at once. It is larger than many standard camping stoves but smaller than full-size outdoor ranges. You get enough room for family meals without needing a massive footprint on your patio or RV counter.
Surface Material: Iron
The cooking plate is made of solid iron, which retains heat well for consistent searing. You must season it with oil before first use to prevent rust and create a non-stick layer. Iron is heavier than steel but offers better heat retention, making it ideal for traditional griddle cooking compared to thin steel plates.
Form Factor: Tabletop
This unit is designed to sit on a stable table or counter rather than standing on the ground. It measures 20.6 inches long and weighs 35 pounds. This size fits well on picnic tables or RV decks. You need a sturdy surface to support the weight, as it is not a ground-level grill.
Design and Build Quality
The listing describes a stainless steel frame that supports the iron cooking plate. This combination offers durability for outdoor settings like patios or camping trips. The unit weighs 35 pounds, making it heavy enough to stay stable during use but light enough to move with care. Its overall dimensions are 20.6 inches in length, 13.7 inches in width, and 14.7 inches in height. This footprint fits standard tabletops without overwhelming small outdoor spaces.
You get a flat top surface measuring 18 by 14 inches. According to the listing, this iron plate provides ample room for multiple items at once. The design includes foldable legs for storage, which simplifies transport in an RV or car. A locking cover protects the surface when not in use. You should season the iron plate with oil before first use to ensure proper performance and prevent sticking.
Controls are managed via individual knobs for each of the two parallel burners. This layout lets you adjust heat zones precisely. You can run both burners for large meals or just one for simple breakfasts. The unit connects to either a 1-pound or 20-pound propane tank using the included valve and hose. This flexibility allows you to choose the fuel source that best suits your cooking duration and location.
Setup and Everyday Use Guide
Setting up the Onlyfire GS318 involves assembling the foldable legs and attaching the locking cover. The unit includes a gas valve for a 1-pound propane cylinder and a hose for a 20-pound tank. You choose the fuel source based on your needs. The 20-pound tank suits longer cooking sessions, while the smaller cylinder offers portability for tailgating or RV trips. The stainless steel frame supports the iron griddle plate, which measures 18 by 14 inches. You must season the iron surface with oil before the first use to ensure a non-stick finish and protect the metal. This step is essential for the classic flat-top cooking experience. During daily use, you control each of the two parallel burners individually. This feature allows you to adjust heat zones for different foods. You can run both burners at 16,000 BTU for large meals or just one for a simple breakfast. The removable grease tray collects drippings, simplifying cleanup after cooking. The folding legs and carrying handle make transport easy. You can store the griddle in a car or RV when not in use. The locking cover protects the cooking surface from debris. The design supports outdoor activities like patio dinners, camping, and backyard gatherings. The stainless steel construction ensures durability during regular use. You do not need additional accessories to start cooking, as the gas connections are included. The tabletop form factor keeps the unit stable on flat surfaces. This setup allows you to cook efficiently without a permanent outdoor kitchen installation.
What You Need Before Buying
Before purchasing, verify your propane setup. This unit supports both 1-pound cylinders and 20-pound tanks via included fittings. Ensure your storage space accommodates its 20.6-inch length and 35-pound weight. The iron surface requires seasoning with oil before first use to prevent rust. You must also purchase a grill cover separately, as it is not included. Clean the removable grease tray after each session to maintain hygiene. This griddle fits well alongside traditional pizza ovens for varied outdoor cooking. It offers a flat-top option that complements open-flame grilling. Check that your table surface can handle the heat and weight. Consider if you need additional tools for flipping food on the large iron plate. This model suits those who want versatile outdoor cooking without building a full kitchen setup. It is a practical addition for patios or camping trips where space is limited.
Check before you buy
- Confirm you have space for the 20.6-inch length.
- Plan to season the iron plate with oil.
- Buy a grill cover since it is sold separately.
- Check propane tank compatibility with included fittings.
