The strongest case for Ultra2 is sustained use between charges. Its weight and high-speed noise make it a less effortless daily carry. It led narrowly on the six performance criteria; with release recency it is third, a 2025 model against two 2026 ones. It is not evidence that everyone will prefer this fan. [50][5, 20, 22, 38, 44]

Buying notes & calculation details
These are retained candidates, not failed products. Life9S, upgraded Pro1 S and Life7 lack sufficient noise votes. Ultra1, base Pro1 and Ultra2 E instead remain identity or local-offer holds. With other scores held fixed, Life9S would lead with a noise score above about 70 out of 100; the overall result remains unresolved. [37, 49]
Room, tower and dedicated neck fans are outside the daily handheld use case. Colours are not separate performance candidates without evidence of different hardware.

Full research & product notes
The complete inventory, alternatives and limits behind the recommendations.
Rubric and evidence standard
Rubric and evidence standard
Best means useful personal airflow that is comfortable to carry and use in Malaysia, with occasional desk use. The rubric was fixed before candidate research; release recency was added afterwards, on 27 September 2026, by standing instruction, and moved the Ultra2 from first to third. There is no budget cap; value has deliberately low weight. The result is not a budget-value ranking or a medical heat-safety recommendation. Visible ordinal ranks are omitted because the narrow lead does not separate a winner; entries retain their computed-score sort for navigation. [44, 45][33]
Criterion
Weight
Why it matters
Useful cooling
31.5%
The main function, including control and sustained output rather than motor speed alone.
Portability
18%
A fan must earn space in a daily bag and remain comfortable to hold.
Battery and charging
13.5%
Useful airflow must last beyond a short demonstration.
Noise
13.5%
Sound and tone affect whether output is tolerable.
Build, safety and support
9%
Documented protection and accessible support matter; prestige does not establish durability.
Value at Malaysian cost
4.5%
Local cost matters, but performance drives this approved question.
Release recency
10%
Added 27 September 2026 by standing instruction: newer models score higher, by formula on a one-year cycle; the other weights were multiplied by 0.9. [47, 48]
The weights total 100%. Manufacturer figures are attributed claims; peak airspeed and maximum runtime usually describe different settings. Reviewer tests are not our own measurements. No full-field matched-airflow test supports a definitive order. Price, stock, release milestone and majority ownership remain explicit decision facts; unknown ownership is not inferred from headquarters. [33, 34, 42]
Scores and reproducibility
Scores and reproducibility
These are Refer’s provisional model assessments. Claude, GPT and Grok independently assessed the same evidence. Each criterion uses the median of at least two votes, followed by the original weighted sum. After finding new original reviews, a targeted follow-up replaced only the noise votes for Pro1 Mini and Life10S; other votes and weights were preserved. The Pro1 Mini noise and Life10S build/support medians each use two votes because GPT abstained. Complete coverage means enough votes per criterion, not unanimous assessment or measured evidence. [42, 45]
The unrounded six-criterion totals are Ultra2 73.35, Dyson 72.60, Pro1 Mini 68.60 and Life10S 66.10. The Ultra2's 0.75-point lead over the Dyson on those criteria is not a meaningful margin of measured superiority. Each published total is 0.9 × the unrounded six-criterion total plus 0.1 × release recency, on a one-year cycle for handheld fans; the Dyson's 4.0-point lead over the Ultra2 comes from recency (77 against 30), not from measured performance. The Dyson is dated from its announcement, the earliest milestone found; a later first sale would raise its recency. [47, 48, 50] The widest criterion spreads were 16, 18, 15 and 17 points respectively; agreement between models does not create independent test evidence. [38, 39, 40, 41, 44]
The strongest evidence distinguishes Ultra2 and Dyson’s endurance, weight, noise and local support. Pro1 Mini and Life10S rely more heavily on specifications and limited qualitative reports. Full criterion coverage means enough model votes to compute the rubric; it does not mean every criterion was measured. There are no validated score anchors for this new product type, so point-scale calibration is another limitation. [5, 7, 9, 20, 21, 31, 35, 36, 42]
What the missing scores could change
What the missing scores could change
These bounds include release recency, as the ranked scores do. Do not silently redistribute the missing noise weight. The intervals below let noise range across its entire scale while every other median stays fixed. They are mathematical bounds, not probabilities or confidence intervals. [43, 49]
Unranked fan
Floor with recency
Possible full total
What noise score would do
Life9S
63.58 (recency 76)
63.58–77.08
Leads with a noise score above 70; passes the Pro1 Mini above 43. [49]
Pro1 S 2025 aluminum
55.40 (recency at most 32)
55.40–68.90
Cannot pass the Ultra2; passes the Life10S above 53. Release and stock also need resolution. [29, 30, 49]
Life7 5000 mAh
47.48 (recency 0 on the 2024 family date)
47.48–60.98
Stays below the Life10S at any noise score; a much newer variant date would raise it. [32, 49]
The Pro1 S interval also retains an earlier value judgement based on RM239; its current RM249 offer has not been rescored. It is not a current-price completed score. [29, 30, 46]
Dividing those contributions by the scored weight would yield plausible-looking totals that omit noise. They are deliberately not used for positions. New comparable evidence may also change already-scored criteria, so these fixed-score bounds do not encompass every source of uncertainty. [43]
What would change this
What would change this
Priority updates are dependable noise evidence for Life9S, upgraded Pro1 S and Life7; exact selected-variant release dates; verified local stock and warranty; and comparable tests across the field. A retailer price is dated evidence, not a guaranteed checkout offer. The research should be refreshed when these change, without tuning the weights to preserve an existing winner. [13, 14, 26, 29, 30, 32, 33, 37, 43]

Original research summary
Dyson HushJet Mini Cool leads at 73.0, ahead of the Jisulife Pro1 Mini (69.3) and Ultra2 (69.0), because release recency, 10% of each score since 27 September 2026, favours the two 2026 models over the 2025 Ultra2. On the six performance criteria alone, Ultra2 and Dyson remain the leading alternatives in this comparison of Jisulife and Dyson handhelds. [50, 48] Choose by endurance, weight and support. Life9S remains unresolved: a noise score above about 70 out of 100 would put it first. That is a bound, not a prediction. [38, 39, 44, 49]
How this was scored
The handheld rechargeable fan that delivers useful personal airflow while being comfortable to carry and use every day in Malaysia. Judge usable performance, portability, runtime and noise together, with a smaller allowance for ownership quality and local price. No budget ceiling is proposed.
Useful personal airflow — 31.5% · Airflow reaching the face and upper body at practical distances, coverage, control and sustained output. Prefer comparable independent measurements. Record manufacturer airspeed, airflow and motor-speed claims with their conditions; do not equate different units or test methods. Contact-cooling features earn credit only for evidenced practical benefit.
Carrying and handling — 18% · Actual mass, packed dimensions, grip, controls, accidental activation protection and useful stand or carrying arrangements, including necessary accessories.
Runtime and charging — 13.5% · Runtime at useful settings, maximum-power runtime, charging time and compatibility. Separate minimum-speed maximum-runtime claims from comparable evidence. Capacity alone is not runtime.
Sound during use — 13.5% · Noise level and tone at useful output, with distance, mode and conditions recorded. Compare equivalent conditions where possible; minimum-setting noise cannot represent maximum output.
Build, safety and support — 9% · Durability evidence, blade/hair protection, battery and charging safeguards, cleanability, warranty and service accessible from Malaysia. Separate documented features from tested effectiveness; limited reliability history is uncertainty, not proof of failure.
Value at Malaysian cost — 4.5% · Useful performance and ownership benefits against dated Malaysian purchase cost, including necessary accessories and unavoidable import costs. Distinguish local warranty from seller or overseas coverage. Do not substitute a converted foreign MSRP for a buyable local price.
Release recency — 10% · Scored by formula, not opinion: min(100, max(0, round(100 × (1 − age_days / 730.5)))), age from the earliest documented release milestone the guide shows (announcement or first sale) to the 2026-09-27 check. Refresh cycle 1 year(s): one cycle old scores 50, two cycles 0; newer scores higher.

Jisulife Japanese company release announces Life9S sales from 2026-04-08: 160 days before 2026-09-15. Japanese sale date is a regional milestone, not verified global first sale.
Upgraded aluminum Pro1 S was available by 2025-05-19 in corporate Weibo coverage of the 2025 upgrade; at least 484 days before 2026-09-15. Exact first-sale day is unconfirmed. Red Design dedicated store advertises RM249; stock unconfirmed. HomePro RM249 listing reports zero stock at its listed stores.
Current upgraded Pro1 S aluminum local offer: RM249 advertised by Red Design with local one-year warranty, variant stock unconfirmed. HomePro exact 2025 grey version also RM249 but listed store stock is zero. This does not establish the older RM239 listing as buyable.
On 2026-09-15 Dyson Stone/Blush remains RM399 and explicitly in stock on its official Malaysia page, with a two-year warranty. Announcement age is 159 days from 2026-04-09. Pro1 Mini Japanese release age is 160 days from 2026-04-08; neither establishes Malaysia first sale.

Life7 family existed by 2024-06-21 in an original hands-on review, but that review may concern the smaller battery. Exact first sale of the selected 5000 mAh variant remains unresolved; no exact release date or age is inferred.
Approved six rubric weights: cooling 0.35, portability 0.20, battery 0.15, noise 0.15, build/safety 0.10, value 0.05. Total 1.00. Scores are evidence-based model judgements rather than hands-on measurements. Manufacturer maxima and minimum-mode endurance are not one operating point.
Editorial scope and weights were fixed before candidate research; the original agreement is retained on file.

CNET’s Anna Gragert reported adequate Pro1 Mini cooling in actual use and a highest-setting phone-app reading of 69.9 dBA. The same article lists Dyson 77.5 and Ultra2 79.9 dBA but explicitly cautions against direct comparison. Measurement distance, ambient conditions and calibration are unstated. This supports only provisional qualitative noise assessment.

The Verge’s Andrew Liszewski used Life10S 5000 mAh and found its lower-pitched sound more tolerable than Dyson’s, though full speed was audible. He timed over 16 hours at unspecified half power. These are reviewer observations, not calibrated or equal-mode comparisons.
Pro1S exact-generation review lead: Cheval Lim’s 2025-09-10 review identifies upgraded 2025 Pro1S, but readable noise/runtime measurements were unavailable. Life9S owner comments describe higher gears as loud, without a measured protocol. These leads do not fill the unresolved noise scores.
Refer provisional panel score for jisulife-ultra2: 73.3/100; criterion medians cooling 84, portability 65, battery 82, noise 52, build-safety 72, value 73; maximum criterion vote spread 16. All six criteria covered. These are model judgements, not measured product performance.

Panel method: Claude Opus 5 via Pareto, GPT-6 Astra through ask-codex, Grok CLI (exact backend not returned). Per-criterion median requires at least two votes. First round covered seven models; follow-up replaced only noise votes for Pro1 Mini and Life10S after new original reviews. Pro1 Mini noise has two votes; other completed criteria have at least two. Weights unchanged. Pareto costs USD0.048324 plus USD0.016073 = USD0.064397; CLI billing is separate.
Original prompts, individual criterion votes and the limited noise follow-up are retained on file. This is an editorial model panel, not independent laboratory testing.
Incomplete fixed-weight score bounds if missing noise spans 0–100: Life9S 62.20–77.20, upgraded aluminum Pro1S 58.00–73.00, Life7 5000 mAh 52.75–67.75. Noise weight is 0.15. Bounds hold other criterion medians fixed; not confidence intervals. Normalizing the scored 0.85 weight would give 73.2, 68.2 and 62.1 respectively; those are not full-rubric scores and are withheld from ranking. Life9S can overtake the current leader.
Known weighted contributions plus a missing noise contribution between zero and fifteen points; other criterion medians are held fixed.
Completed weighted totals before display: Ultra2 73.35, Dyson 72.60, Pro1 Mini 68.60, Life10S 66.10. Refer’s existing floating-point rounding displays Ultra2 as 73.3, not a separately adjusted judgement. Displayed lead over Dyson is 0.7; this precision cannot establish a meaningful performance difference. All completed entries retain the entire 1.00 rubric weight.
Sum of published criterion medians times approved weights; ordinary service display rounding is retained.
Challenge revision: model votes confirm GPT omitted Life10S build/support as well as Pro1 Mini follow-up noise. Their medians use two votes. No visible ordinal rank is warranted by the narrow Ultra2–Dyson margin. Complete score coverage is a voting rule, not a claim of measured evidence. Life9S overtakes Ultra2 under fixed other medians only if its missing noise assessment exceeds 74.3333; that mathematical possibility is not a prediction. Pro1 Mini automatic high confidence reflects coverage/spread only and is not adopted as evidence confidence.
Individual votes and independent review are retained on file. Conditional missing-score bounds are not forecasts.
The unranked Pro1 S initial value assessment used an older advertised RM239 offer. The current checked offer is RM249; value has not been rerun at that price. Its 58.00–73.00 noise-only interval keeps the earlier value median fixed and is not a current-price completed score. Life7 initial prompt explicitly updated the selected pink 5000 mAh offer to RM99.
The original panel input is retained on file. Current retailer observations are separately cited; the old price is not offered as a current purchase price.

Missing-noise bounds with release recency (0.9 × the [43] contribution + 0.1 × recency + 0.135 × noise, noise 0–100), ages at 27 Sep 2026. Life9S: Japan sale 8 Apr 2026, 172 days, recency 76; 63.58–77.08. It passes the Dyson (73.04) at a noise score above 70.1, the Pro1 Mini (69.34) above 42.7 and the Ultra2 (69.02) above 40.3. Pro1 S 2025 aluminum: available by 19 May 2025, at least 496 days, recency at most 32; 55.40–68.90 at most, so it cannot pass the Ultra2 and passes the Life10S (62.49) above 52.5. Life7 5000 mAh: family existed by 21 Jun 2024, at least 828 days, recency 0 on that date; 47.48–60.98, below the Life10S at any noise score; the selected variant's own date is unknown, and if it were brand new (recency 100) the range would be 57.48–70.98. Mathematical bounds with other medians fixed, not probabilities.

Totals with recency, recomputed from the unrounded six-criterion totals (0.9 × total + 0.1 × recency from [48]), in order: 1 Dyson HushJet Mini Cool 72.60 → 73.040 (73.0); 2 Jisulife Pro1 Mini 68.60 → 69.340 (69.3); 3 Jisulife Ultra2 73.35 → 69.015 (69.0); 4 Jisulife Life10S 66.10 → 62.490 (62.5). The earlier totals row used the Ultra2's displayed 73.3 and gave 68.97; every displayed score is unchanged. Recency ages are milestone-dependent: the Dyson is dated from its 9 Apr 2026 announcement, the earliest milestone found, so a later first sale would make it younger and raise its recency, not lower it; the Pro1 Mini is dated from its Japanese sale and the Ultra2 and Life10S from their Chinese sale.
