Model details
Understand the model and package.
Package reference
Choose one battery in total or a package with one additional battery in the purchase section.
Confirm the supplied carrying accessories, power adapters, nasal tubing, filters and remote with your selected package. Car-power accessories and tubing quantities can differ between versions.
Check package detailsBattery and charging notes
The manual describes a removable rechargeable battery. Confirm its capacity and connector version with your order; do not assume every replacement battery is compatible.
The internal battery does not charge while the unit is running on AC or DC power. The timer is not a runtime indicator, and an additional battery does not imply uninterrupted changeover.

| Product PositioningDiferente | Compact and portable for convenient measurement anytime | A balanced choice for everyday home monitoring | A simpler, user-friendly solution for routine home measurement |
| Measurement SiteDiferente | Wrist | Upper arm | Upper arm |
| How It WorksDiferente | An inflatable wrist cuff applies pressure to the wrist artery. Oscillometric technology detects pulse oscillations to calculate systolic pressure, diastolic pressure, and pulse rate. | An inflatable cuff wraps around the upper arm. Oscillometric technology detects pressure oscillations to calculate systolic pressure, diastolic pressure, and pulse rate. | Place the upper arm into the integrated arm cylinder. The device automatically inflates and uses oscillometric technology to measure blood pressure and pulse rate. |
| How to Wear / UseDiferente | Wrap the integrated cuff directly around the wrist | Wrap the separate cuff correctly around the upper arm | Place the arm directly into the integrated arm cylinder; no separate cuff wrapping required |
| Ease of UseDiferente | Easy, but wrist positioning is more sensitive during measurement | Straightforward; correct cuff placement is required | Very intuitive, with fewer cuff-wrapping steps |
| Measurement PostureDiferente | Keep the wrist at heart level; remain still and do not talk | Sit steadily with the upper arm relaxed and supported at heart level | Sit steadily, place the arm naturally into the arm cylinder, keep it supported and remain still |
| PortabilityDiferente | ★★★★★ Excellent | ★★★★☆ Very Good | ★★☆☆☆ Best for a fixed home location |
| Storage ConvenienceDiferente | Compact size, convenient for carrying | Main unit + cuff; suitable for home storage or travel | Integrated design with a larger footprint; ideal for long-term tabletop placement |
| Typical Use ScenariosDiferente | Travel, business trips, office use, quick measurements | Everyday home use, regular blood pressure tracking, family health monitoring | Fixed home monitoring, routine use by older adults, frequent use by multiple family members |
| Ideal UsersDiferente | Users who prioritize portability, travel frequently, or want quick and convenient measurements | Most home users and those who prefer a standard upper-arm measurement method | Older adults, users with limited hand dexterity, and those who prefer fewer cuff-placement steps |
| Key AdvantagesDiferente | Compact & portable / One-touch measurement / Large display | Upper-arm measurement / Adjustable cuff / Flexible home use | Integrated arm cylinder / Fewer setup steps / Large easy-to-read display / Tabletop design |
| Things to ConsiderDiferente | Wrist position can significantly affect readings. Follow the instructions carefully and keep the wrist at heart level. | Correct cuff size and placement are important. A cuff that is too loose, too tight, or incorrectly sized may affect measurements. | Requires more space than compact monitors; correct sitting posture and arm position should still be maintained according to the instructions. |

Lee la concentración y el flujo juntos. Las cifras proceden de los manuales de cada modelo y dependen de las condiciones de funcionamiento. No son una recomendación para ajustar el oxígeno. Para la idoneidad médica, sigue las indicaciones de tu profesional sanitario. Un guion indica que la versión suministrada necesita confirmación; no equivale a cero y se excluye del resaltado de diferencias.
Condiciones de flujo y orientación por modelo
ZY-01: ≥90% applies at the maximum recommended flow of 1 L/min. Do not assume the same concentration at higher settings. The manual describes approximately 30 minutes of startup to reach maximum concentration.
ZY-05: The manual states ≥90% up to the maximum recommended flow of 5 L/min at zero outlet back pressure, reaching the specified concentration within 30 minutes of initial startup. Its ZY-05 graph covers 1–5 L/min. Altitude and operating conditions affect concentration.
SJ-OX1C: The manual specifies 93% ±3% at 1 ±0.2 L/min and 30% ±5% at 6 ±0.5 L/min. The adjustable flow range is not a guarantee of high concentration at every setting. Battery and car-power accessories depend on the package. Confirm compatibility before ordering; no single battery runtime is promised here.
These startup times describe equipment operation, not a treatment duration. Compare the figures with the manual and label supplied with your unit. Weight is not quoted while supplied-version details remain unconfirmed.

Condiciones de prueba de WH-02 y orientación por modelo
Source: Ziqing's updated product comparison. WH-02 nebulization rate (0.32 mL/min) and noise (≤55 dB) are customer-confirmed actual measurements. The original WH-02 manual lists approximately 0.16 mL/min and ≤65 dB; it has not been modified. Test conditions for the updated measurements were not provided, so the manual's test conditions are not attributed to these values.
Specifications and portability/practicability ratings are supplied by Ziqing, not an independent performance ranking. Confirm the exact version, power supply and accessories for your device. Unspecified values are not counted as verified differences.
Helpful answers
Questions, answered.
Is oxygen concentration the same at every flow setting?
No. The SJ-OX1C manual lists 93% ±3% at 1 ±0.2 L/min and 30% ±5% at 6 ±0.5 L/min. Concentration decreases as flow increases. These are manual-listed endpoints, not advice about your settings. Follow your healthcare professional's guidance and read the complete specifications.
How do the two battery packages differ?
The first option includes one battery in total. The second includes that battery plus one additional battery. Confirm the supplied battery capacity, connector version and other accessories with our team. An additional battery is not a guarantee of a particular total runtime or uninterrupted operation.
Can the internal battery charge while the machine is operating?
The supplied model manual states that the internal battery does not charge while the concentrator is running on AC or DC power. Follow the charging instructions for the matching adapter and battery; do not assume simultaneous charging or uninterrupted battery changes. See battery precautions and charging instructions.
Does the 180-minute timer describe battery runtime?
No. The manual describes a timer with 15-minute increments up to 180 minutes. This is a control setting, not battery runtime or a recommended treatment duration. Battery version, condition and operating settings need to be considered separately.
How should I clean the outer housing?
Switch off and disconnect the power supply first. Follow the manual's external cleaning instructions, keeping liquid out of the unit and its connections. Do not immerse the housing, use alcohol or oil-based cleaners, or open it for internal repairs. Read the full cleaning and maintenance instructions.
What if a warning appears or oxygen delivery stops?
Follow the instructions supplied with your unit. For unresolved faults, stop using the faulty device, follow the backup arrangements agreed with your healthcare professional and contact your equipment provider. Seek immediate medical help if you feel unwell or have an emergency. This website form is not an emergency service.
Which option should I select?
Match the available option to the version you need. For mains-powered devices, check the plug and voltage on the product label before use. Ask our team if you are unsure about compatibility.
Where can I find shipping and return information?
Read our shipping policy and refund policy for the store's current terms.
