portable power station
China manufacturers
Gravity crush test
We test each batch of batteries to their limits to guarantee 100% product safety
Test conditions
- Pressure applied up to 13kn ± 0.78kn.
- Battery voltage drop of at least 100mv.
- Battery deformation of 50% or more of original thickness.
Qualification criteria: the temperature of the battery casing does not exceed 170°C, no disintegration, no rupture and no fire in the battery within 6H after the test.
Test conditions
- Vibration type: Sine logarithmic sweep.
- Frequency range: (7-200-7) Hz (crossover frequency at approx. 50 Hz).
- Sweep period: 15 min (7Hz-200Hz-7Hz, sweep rate approx. 0.6ct/min).
- Displacement amplitude: 0.8 mm.
- Acceleration amplitude: 80m/s2 (8gn).
- Duration: 12 cycles in each direction, 3H in total.
- Test direction: 3 mutually perpendicular axes, in sequence.
Qualification criteria: no leakage of liquid, no gas, no disintegration, no rupture and no fire after the test.
Vibration testing
Battery high and low temperature limit testi
High and low temperature impact test 10 times at 100°C±2°C and -40±2°C.
Charge and discharge anti-explosion test
Temperature -10℃~4010℃ Temperature ≤80% Atmospheric pressure 70kPa~106kPa Overcharge and overdischarge test
Shock test
Acceleration 150gn pulse width 6ms Battery 50gn pulse width 11ms 18 times shocks to maintain the battery voltage above 90%.
Pre-factory ageing test
Aging test with a standard charge/discharge of 1C and three cycles of not less than 15H.
During the charging process, the device gets hot and explodes, resulting in a safety accident.
False descriptions of product specifications, different markings from actual conditions.
The most common quality problems
Inverter shuts down when the load exceeds 50w AC.
Poor battery storage and automatic loss of power.
Short battery life, no intelligent power management.
Battery life decreases after a year or even a few months of use.
The power level is shown as 35% output and immediately drains to 0% when charging.
Output charging is automatically withdrawn from charging after 10-20 minutes
These Are The Quality Issues That Annoy Users, See How We Solve Them In Terms Of Product Design, Raw Material Testing, Production Processes Control, Quality Control And Extreme Testing?
What Are The Advantages Of A Sine Wave Output?
The sine wave output has several advantages, including.
- Wide compatibility.
- Low distortion.
- Predictability.
- Efficient power transmission.
- Reduced heat generation.
How to choose a safer portable power station?
- Cooperation with regular and qualified factories
- Choose lithium iron phosphate battery
- Products must pass safety certification
- Before leaving the factory, the device must go through 15H aging test, -40℃~+100℃ high and low temperature test, pinprick test, gravity squeeze test and other extreme tests.
Is the power stored in the mobile power automatically lost when it is not used for a long period of time?
Our products are designed with the world’s best quality original components and spare parts, and break through the limit of low power consumption in technology, so that only a small portion of the power will be lost after more than a year of full charge storage.
We have broken through the BMS power management technology in our product development, combined with the LED digital display, the power of the mobile power station can be monitored in real time; lithium iron phosphate battery combined with ultra-low power consumption technology, so that our product cycle life of more than 3000 times.
How to improve the product life of the mobile power station?
- For the conversion of the power supply battery is recommended to charge and discharge it once every 1~2 months to maintain the battery, which can effectively extend the service life of the power supply.
- The correct use method, should be based on the product manual, choose the correct charging and discharging accessories, or use our charging kit.
- According to the actual use of the situation to choose the right power supply power.
- Dry and ventilated storage conditions, avoid extra long periods of exposure to the sun or rain.
Some of theProcurement trapsyou may encounter
Using used batteries or IC to lower the price
False labeling of parameters, (the actual use of power does not reach the labeled data)
Adding lead blocks inside the product to boost the weight of the product to disguise the quality with falsehoods
