Capacity and family fit
Size guide · Tiger JNP conventional cookers
Choosing a Tiger JNP size: 0550, 1000, 1500, or 1800
The JNP family keeps its control scheme simple: a physical cook switch, a Plain white-rice method, and an automatic transition to Keep Warm. Capacity is what changes most between the current U.S. JNP-0550, JNP-1000, JNP-1500, and JNP-1800. The manual’s batch boundaries do not all start at the same point, so picking by the largest number alone can leave you with a cooker that is awkward for your everyday portions.
Compare the actual manual ranges
| Exact model | Capacity | Plain white batch | Listed body (W×D×H) | Rated power / weight |
|---|---|---|---|---|
| JNP-0550 | 0.54 L | 1–3 supplied cups | 9.1 × 8.7 × 8.8 in | 305 W / 4.6 lb |
| JNP-1000 | 1.0 L | 1–5.5 supplied cups | 10.7 × 9.8 × 10.3 in | 505 W / 6.4 lb |
| JNP-1500 | 1.5 L | 3–8 supplied cups | 11.8 × 10.7 × 10.7 in | 560 W / 7.7 lb |
| JNP-1800 | 1.8 L | 3–10 supplied cups | 11.8 × 10.7 × 11.7 in | 650 W / 8.1 lb |
Tiger defines the included cup as about 0.18 liter or 5.29 ounces, roughly 150 grams level. These are dry rice inputs, not cups of cooked rice. In particular, the two largest models start at three cups; the JNP-1500’s eight-cup ceiling does not make a two-cup meal an approved batch. JNP-0550 and JNP-1000 both begin at one cup, but the second has more room for a meal that grows from a small serving to a medium batch.
Decide from your ordinary portion first
If one to three cups covers nearly every meal, JNP-0550 uses the least counter space and is the lightest. If you need the same low minimum but sometimes cook around five cups, JNP-1000 gives you more headroom. For a household that almost always cooks at least three cups, JNP-1500 extends the top to eight; choose JNP-1800 when the extra two cups are a recurring requirement. The 1800 has the same stated width and depth as the 1500 but stands an inch taller and weighs about 0.4 pound more. Do not infer a faster cycle from its higher wattage; Tiger’s page does not promise a cooking time comparison.
Check your countertop or shelf as well as the footprint. The manufacturer lists closed dimensions, while the manual advises at least 11.8 inches between the cooker and nearby walls or furniture. That clearance and the steam path can matter more than a small difference in listed body size. The official family image is not capacity-marked, so use the model suffix and the specification table rather than trying to identify size from the photograph.
Know what all four models do not add
None of these four is documented with a delayed-finish timer, pressure cooking, a brown-rice or porridge program, or an included basket for steaming food over rice. You start the physical switch when you are ready. After the cycle, Keep Warm begins automatically, but it is for white rice, not for scheduling dinner or keeping every recipe warm. Tiger’s manual says not to hold the rice longer than 12 hours and cautions against warming tiny amounts, cold rice, or mixed and seasoned rice.
All four have aluminum inner pots with a nonstick lining. The U.S. disclosure names each of these exact models in the PFAS-intentionally-added group for nonstick properties. That is a materials statement rather than a health conclusion; it also is not a certification that the cooker is PFAS-free. If your material requirement excludes that disclosure, compare another pot type instead. If you choose a JNP, protect the coating by washing rice in another bowl, using the supplied or wooden spatula, and hand-washing removable parts with a soft sponge.
One neighboring model name deserves care
Tiger also lists JNP-S capacity variants. Although their names and simple switching arrangement are related, treat JNP-S and JNP as separate exact model identities: check the suffix, capacity row, dimensions, and listed weight before shopping. A larger capacity ceiling does not imply the models share interchangeable pots or every configuration detail. You can read the separate reviews for JNP-0550, JNP-1000, JNP-1500, and JNP-1800 before narrowing your choice.
Practical rule: write down the smallest batch you actually make, then the largest one you make more than occasionally. Choose a single model whose manual range covers both. If no size fits both, the tradeoff is not solved by the JNP family’s simple switch: look for a different cooker with the batch range or menu you need.
