The Char-Griller Flex Fuel Plus 3-in-1 Combo Grill lets you cook with gas, charcoal, and a flat-top griddle in one unit. If you need char griller flex fuel plus 3 alternatives, this list compares seven options based on overlapping specifications. The original model offers 1,260 square inches of cooking space and 30,000 BTUs of gas power. It includes dual dampers for charcoal control and fits outdoor backyards.

You can compare dimensions, fuel types, and control mechanisms to find the right fit. Each selection addresses a specific gap left by the original unit. The goal is to help you choose based on measurable features rather than brand loyalty.
How each alternative compares
Masterbuilt Gravity Series 800 Charcoal Smoker Grill
The Masterbuilt Gravity Series 800 replaces manual charcoal management with digital automation. It lacks gas or griddle functions, focusing solely on charcoal smoking. You gain app control and precise temperature regulation, which the Flex Fuel Plus does not offer. Its 800-series capacity is slightly smaller than the Flex Fuel’s 1,260 square inches. The unit weighs 204 pounds, making it heavier than the original. Choose this if you want set-and-forget charcoal cooking without managing dampers or charcoal trays. It is best for cooks who prioritize consistent smoke results over multi-fuel versatility.
COMVIEE Masterbuilt Gravity Series Switch Kit
This COMVIEE kit is not a grill but a repair part for Masterbuilt Gravity models. It replaces failed hopper switches on digital charcoal grills. It has no cooking surface, fuel type, or dimensions comparable to the Flex Fuel Plus. You should only consider this if your Masterbuilt unit has a broken switch. It offers no alternative cooking experience. The item weighs 1.45 ounces and is designed for specific MB-1 set switches. It is a niche component for maintenance, not a standalone cooking appliance. Avoid this if you are looking for a complete grill replacement or new cooking hardware.
Char-Griller 22-Inch Steel Kettle Charcoal Smoker
The Char-Griller 22-Inch Steel Kettle is a compact charcoal-only option. It sacrifices the gas burners, griddle, and smoker chamber of the Flex Fuel Plus. Its cooking capacity is significantly smaller, fitting solo cooks or couples. The unit measures 26 by 23 by 38 inches and weighs just 22.3 pounds. It is much lighter and easier to move than the large Flex Fuel Plus. You give up multi-fuel versatility for traditional kettle grilling simplicity. Pick this if you have limited space or budget for a dedicated charcoal grill. It is ideal for small backyards where the Flex Fuel Plus would be too large.
Sophia & William 941 sq. in. Offset Charcoal Smoker
The Sophia & William Offset Smoker offers 941 square inches of cooking area, which is less than the Flex Fuel Plus’s 1,260 square inches. It runs on charcoal only, lacking gas and griddle capabilities. It weighs 123 pounds and measures 61 by 29.5 by 52.2 inches. This model is built for manual smoke management and large gatherings. You gain a dedicated offset smoker design but lose the convenience of gas ignition and griddle cooking. Choose this if you prefer traditional offset smoking over multi-fuel flexibility. It suits enthusiasts who want sturdy construction and raw capacity without digital controls or gas burners.
Char-Griller Smokin Pro Offset Smoker
The Char-Griller Smokin Pro Offset Smoker is a dedicated charcoal smoker with extra-large capacity. It lacks gas burners and a griddle plate entirely. The unit measures 60 by 30 by 52 inches and weighs 115 pounds. It provides substantial cooking space for serious smoking but requires manual temperature control via dampers. You trade the Flex Fuel Plus’s versatility for a specialized smoking experience. This model is best for backyard cooks who prioritize authentic smoke flavor and manual control. It is not suitable if you need quick gas grilling or flat-top cooking. It fits those who want a dedicated smoker rather than a combo unit.
Sophia & William 17-Inch Vertical Charcoal Smoker
The Sophia & William 17-Inch Vertical Smoker is a compact charcoal unit. It has no gas or griddle functions, focusing only on vertical smoking. It measures 21.7 by 11.5 by 31.5 inches and weighs 23.3 pounds. This is significantly smaller and lighter than the Flex Fuel Plus. It is designed for small patios or camping trips. You give up large cooking capacity and multi-fuel options for portability. Choose this if you have very limited space or need a lightweight smoker. It is ideal for small batch smoking and does not replace the versatility of the Flex Fuel Plus for large gatherings.
