Direct Clamps (Bypass Clamps):
Direct connection, no protection. Accidental contact between the positive and negative terminals can cause a short circuit (use with caution).
Regular Clamps (Standard Clamps):
Feature reverse charge protection, but accidental contact between the positive and negative terminals can still cause a short circuit (use with caution).
Smart Clamps (Intelligent Clamps):
Feature high/low voltage protection, voltage detection, reverse charge protection, reverse polarity protection, start timeout protection, and short circuit protection. They are more convenient and safer to use.
The internal battery may heat up, swell, and in serious situations, produce dense smoke.
The battery clamp connecting cable is rated 10 AWG, and its outer insulation can withstand a maximum temperature of 200°C.
We can provide UN38.3, MSDS, EMC, UL, FCC, IEC, CE, RoHS, and other certifications. We also support customer‑specified certification requirements.
Continuous inflation exceeding 10 minutes triggers overheat protection, halting inflation and starting a 180s cooling timer. Inflation resumes after the countdown.
5~6A
For example：
22200mwh: up to 18 normal uses per full charge
29600mwh: up to 21 normal uses per full charge
37000mwh: up to 30 normal uses per full charge
（it depends on usage and environment）
The battery heats up, and after reaching a certain cycle limit, it will swell and fail to start.
For example:
With 37000mWh, it can inflate approximately 3 car tires from completely flat to full pressure.
Models B3 / B5 – Tire size: 700×25C
0~60 PSI: 11 inflations per full charge
0~80 PSI: 7 inflations per full charge
0~100 PSI: 4 inflations per full charge
0~120 PSI: 2 inflations per full charge
Models B1 – Tire size: 700×25C
0~60 PSI: 8 inflations per full charge
0~80 PSI: 5 inflations per full charge
0~100 PSI: 3 inflations per full charge
0~120 PSI: 2 inflations per full charge
The test results were obtained using larger inner tubes (sizes 25/28/32). If smaller inner tubes (sizes 18/20/23/25) are used instead, both the efficiency figures and the battery endurance will improve.
It is approximately 30 μA.

pc+abs .We can also customize according to customer requirements.
Paragraph 1 – Pure PC characteristics
Pure PC (polycarbonate) offers extremely high strength and rigidity, good heat resistance, and excellent dimensional stability, making it suitable for structural components that bear mechanical loads or operate at elevated temperatures. However, its melt viscosity is very high, resulting in poor flowability and difficult injection molding, which reduces production efficiency. Additionally, the material is relatively brittle and has poor resistance to stress cracking, making it prone to fracture under internal stresses. Moreover, the cost of pure PC is high, significantly increasing the overall product price if used alone.
Paragraph 2 – Pure ABS characteristics
Pure ABS (acrylonitrile butadiene styrene) excels in processing: its melt flow is outstanding, enabling easy injection molding of complex, thin‑walled parts. It also has good toughness, a high‑gloss surface finish, and is easy to coat, plate, or otherwise secondary‑process. Its cost is relatively low. On the downside, ABS has noticeably inferior heat resistance, with a lower continuous service temperature, and its strength and rigidity are far below those of PC. It also performs poorly in outdoor weathering, tending to age and become brittle over time.
Paragraph 3 – Overall advantages of PC+ABS alloy
PC+ABS alloy, through polymer blending, successfully combines the beneficial properties of both materials: it retains the high strength, rigidity, and thermal resistance of PC while incorporating the excellent processability and toughness of ABS. This effectively overcomes PC’s processing difficulties and brittleness, and simultaneously elevates ABS’s heat resistance and mechanical strength. As a result, the alloy provides the mechanical performance and thermal stability required for product housings, while also ensuring manufacturing efficiency and cost control – achieving an ideal “rigidity‑plus‑toughness” balance. This is precisely why PC+ABS has become one of the most widely used enclosure materials in consumer electronics, home appliances, automotive parts, and many other fields.
Yes. We provide high‑rate lithium‑polymer battery packs specially designed for jump starters, supporting instantaneous high‑current discharge.
Lead‑acid: Heavy (3‑5kg), short cycle life (~200 cycles), high self‑discharge – not suitable for portable emergency use.
Lithium iron phosphate (LiFePO₄): Long life (>2000 cycles) and good high‑temperature tolerance, but its volume is about 25% larger, weight higher, and cost greater than polymer – better for heavy‑duty applications rather than portable devices.
Ordinary Li‑ion (e.g., 18650): Steel‑cased with liquid electrolyte; prone to explosion in case of short‑circuit or damage – high safety risk.
Conclusion: Polymer batteries offer the best overall balance of size, weight, safety, and high‑current discharge, making them the mainstream choice for portable jump starters.
Common capacities range from 22200mwh to 59600mwh, and we support customisation based on customer requirements
Our cells support up to 60C instantaneous discharge rates. A 37000mwh pack can deliver a peak current of 800-3000A , sufficient to start 9.0L petrol and 7.0L diesel vehicles.
With high‑quality polymer cells, the cycle life is ≥1000 cycles
-30℃ to 65℃
This is normal. The battery level indication is based on voltage. When the battery capacity is small and the operating current is high, the voltage is pulled down due to internal resistance, so the level display drops. When the load stops, the voltage recovers and the indicator goes back up.
Yes, we can customize everything from LOGO, housing color, packaging, and specific parameters to the overall product design — a complete tailored solution.
Yes, all our capacities are honestly labeled.
We have a complete and strict quality inspection process, from components to finished products, with checks at every stage. Specifically, it includes the following 9 key steps:
PCB Incoming Inspection – Inspect printed circuit boards for appearance and quality to ensure components meet requirements.
Battery Capacity & Internal Resistance Test – Test cell capacity and internal resistance to ensure battery performance meets standards.
Basic Function Check – Check open‑circuit voltage, polarity, and appearance to verify basic functionality.
SMT First‑Article Verification – Perform first‑article soldering and alignment check before SMT production to ensure accurate placement.
Structural Assembly Verification – Check for assembly interference to ensure proper fit and mechanical compatibility.
Environmental Reliability Test – Conduct high/low temperature, humidity, vibration, and aging tests to verify stability under various conditions.
Startup Performance Test – Test load startup and transient response to ensure reliable performance in actual use.
Battery Activation & Health Monitoring – Activate the battery and monitor its health status to ensure it is in good working condition.
Charge/Discharge Efficiency & Protection Test – Test charge/discharge efficiency and overcurrent protection to ensure the power management system operates correctly.
