Our take
Tiger NFI-A800-XS is not an electric countertop cooker. It uses a stovetop boil followed by passive cooking in a vacuum-insulated outer vessel, with 8.0 L / 8.5 qt capacity and stainless XS finish. Tiger describes food staying near 160°F for up to six hours under its stated conditions. This is a distinct alternative for cooks who can perform the initial heating step and want a non-electric hold; the retention number is not a recipe-completion guarantee.
Buyers who can bring the inner pot to a boil on a stove and want to continue cooking in an insulated vessel without powered heat..
It is not for anyone who needs the appliance to heat ingredients from cold, run an electric timer, or finish every recipe without monitoring.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Tiger identifies the NFI-A800 as an 8.0-L / 8.5-qt model and maps XS to stainless steel.
- The insulated vessel continues cooking after the inner pot is brought to a boil on a stovetop.
- The exact current Amazon page names NFI-A800-XS and supports a direct model-matched destination.
What to weigh up
- The inner pot must first be heated on a stove; the outer vessel does not heat food from cold.
- The six-hour retention description is conditional and does not guarantee a recipe will be cooked through.
- No electric timer, powered warming mode, dishwasher guidance, or recipe-specific cook time is established.

What the features mean for you
A larger thermal model, not an electric slow cooker
Tiger's official NFI-A600/A800 page identifies the A800 as an 8.0-L / 8.5-qt thermal cooker and distinguishes it from the smaller A600. The current Amazon item page names model NFI-A800-XS, which is the stainless variant. The system has an inner pot and an insulated outer vessel; the latter retains heat rather than adding power. That makes capacity and operation different from a plugged-in slow cooker, even though both support long cooking. The product is a candidate for one-pot meals only when the user can perform the initial heating stage. Its dimensions are approximately 14.7 by 12.4 by 10.4 inches according to Tiger.
The cooking sequence starts on a stovetop
Tiger describes bringing the food to a boil in the inner pot on a stove, then placing that pot inside the vacuum-insulated outer container. The retained heat continues the cooking process without a powered heating cycle. The outer vessel is not a substitute for a stove: it does not take cold ingredients and heat them to a boil by itself. This method calls for a separate burner and a transfer step, so it fits a different kitchen routine from loading an electric slow cooker in the morning. Tiger's product page supports stovetop-start use, but the saved record does not establish an oven mode or dishwasher instructions.
Treat the heat-retention figure as conditional
Tiger describes the cooker as retaining food near 160°F for up to six hours under its stated conditions. That is a maker claim about heat retention, not a universal temperature curve or assurance that a particular roast, grain, or stew will finish in that time. The starting temperature, amount of food, room conditions, and recipe can matter, and this source record does not provide a recipe-specific cook duration. Do not use the six-hour figure as an automatic timer or safety guarantee. The product has no electric mode that turns itself to Warm or Off; the thermal vessel passively holds heat after transfer.
Stainless construction and capacity are model-specific
The official Tiger page distinguishes the A800 capacity from the A600 and identifies the XS finish as stainless. The current listing independently names NFI-A800-XS and gives the same 8-L model context, supporting a direct exact-ASIN link. The 8.5-qt equivalent is a capacity description; it should not be confused with the 271-ounce number in the listing as an independent vessel measurement. The sources do not establish dishwasher safety, a glass lid, powered wattage, or electrical voltage. Check the instructions for cleaning and handling, and keep the stainless finish separate from other NFI-A family codes.
Choose the method before choosing the capacity
The A800 is a strong fit only when the stovetop-boil and insulated-transfer routine suits your kitchen. Someone looking for a programmable appliance that heats from cold should choose an electric model instead. The product's large capacity and passive heat retention are documented; exact recipe results are not. Tiger's product page lists dimensions that help with storage planning, but not a current price or availability. The exact Amazon item confirms the model and ASIN, while the retailer or maker must still supply the included components and full instructions. This review is about the documented mechanism, not a personal cooking test.
What else to compare
For an electric cooker with a timed program and automatic Warm, Hamilton Beach 33567 uses a powered base and stovetop-safe searing insert; the cooking method and care are different.
Before you buy
Does the Tiger A800 heat food from cold?
No. Tiger's method starts by bringing food to a boil in the inner pot on a stovetop, then transferring it to the insulated vessel.
Does six hours mean every recipe will be done?
No. Tiger's heat-retention statement applies under stated conditions and is not a recipe-specific completion guarantee.
Is this an electric cooker?
No powered heating cycle is documented; the cooker relies on heat retained by its insulated outer vessel.

The decision
Tiger NFI-A800-XS is an 8.0-L / 8.5-qt non-electric thermal cooker with a verified current exact listing. It requires a stovetop boil first, and its conditional heat-retention claim is not a promise of recipe completion.
