Power Bank Manufacturing Company in Vietnam
Power Bank Manufacturing Company in Vietnam
Portable power banks have become a familiar accessory for smartphone users, especially those who frequently travel, work outdoors, or work away from home. However, despite their convenience, the risk of fire and explosion from power banks remains a significant concern if the product is of poor quality or used incorrectly. In fact, numerous cases of house fires, burns, and property damage have been recorded as a result of using substandard power banks.
MyMyTechnology As a power bank manufacturing company in Vietnam, we clearly analyze the main causes of fires and explosions and how users can effectively prevent them.
Low-quality power banks are the leading cause. -MyMyTechnology
Currently, power banks are sold on the market at a wide range of prices, from tens of thousands to over a million VND depending on capacity and brand. However, a price that is too cheap compared to the advertised capacity is usually a warning sign.
For example, a 10,000 mAh battery priced at less than 200,000 VND or a 20,000 mAh battery priced at around 300,000 VND is highly likely to be of poor quality, counterfeit, or have inflated capacity claims.
- Using cheap, substandard battery cells.
- There is no overvoltage or overcurrent protection circuit.
- Not inspected for safety before shipment.
- The storage capacity was inflated multiple times.
There have even been cases where battery cores have been filled with substitute materials like sand to increase weight, but without the actual ability to store electricity. These types of batteries pose a high risk of fire and explosion due to the lack of control over the incoming and outgoing current.
Uncontrolled power supply is a dangerous factor. -MyMyTechnology
A standard power bank must have a battery management system (BMS) that helps:
- Voltage control
- Charging current limit
- Prevent overheating
- Automatically shuts off when full.
Low-quality batteries often lack or have rudimentary protection circuitry. When the charging current exceeds the allowed limit, the battery can heat up rapidly and lead to thermal runaway, causing fires or explosions.
Additionally, unstable discharge current can damage phones, tablets, or other devices that are charging.
The habit of leaving your phone plugged in overnight or for several consecutive days. -MyMyTechnology
One of the common causes of fires is the habit of leaving power banks plugged in continuously for hours, or even days.
Most products on the market lack an automatic shut-off feature when fully charged. This causes the battery to continue drawing power even after it's full, leading to prolonged overheating and potentially short circuits.
Even with batteries that have a control circuit, if the power supply is unstable or the environment is too hot, the risk of malfunction can still occur. Therefore, users should not:
- Charge it overnight.
- Leave the battery charging continuously for several days.
- Charging in a confined, poorly ventilated area.
High temperatures and humid environments are triggering factors for the risk. -MyMyTechnology
Lithium-ion batteries are very sensitive to temperature. When placed in high-temperature environments such as:
- Inside a closed car
- Near the stove, there is a heat-emitting appliance.
- Under direct sunlight
The chemical reactions inside the battery can accelerate and become unstable.
Additionally, humid environments or unstable voltage can also cause short circuits, generating sparks and leading to fires.
Plugging in the charger with wet hands or allowing the device to get wet while charging also poses a potential risk.
Warning Signs That Your Battery Is About to Fail -MyMyTechnology
Users should stop using the product immediately if they notice any of the following signs:
- The battery gets unusually hot during charging or discharging.
- The battery casing is swollen and deformed.
- There is a burning smell or smoke.
- Abnormal charging time
- The charger runs out of power very quickly despite its large capacity.
Swelling is usually caused by gas accumulating inside the battery cell as the electrolyte decomposes. Continued use increases the risk of explosion.
The Role of Reputable Power Bank Manufacturers in Vietnam -MyMyTechnology
In certified manufacturing companies, power banks must undergo several testing steps, such as:
- Check the continuous charge-discharge cycle.
- High current load test
- Temperature control evaluation
- Short circuit protection test
- Impact and vibration testing
In addition, the components used must meet standards, the battery core must be genuine, and it must have an intelligent power management system.
Investing in quality control processes helps minimize the risk of fire and explosions and ensures a long product lifespan.
How to Use a Power Bank Safely-MyMyTechnology
To reduce the risk of fire and explosion, users should:
- Buy products from reputable brands.
- Don't be tempted by high storage capacity at a low price.
- Do not leave it charging overnight.
- Unplug the power when the battery is full.
- Charge in a well-ventilated area.
- Avoid high temperatures.
- Dry your hands before plugging in the charger.
- Use a stable power supply.
When not in use for extended periods, maintain the battery level at around 50–70% and store in a cool, dry place.
Properly Dispose of Expired Batteries -MyMyTechnology
Lithium-ion batteries should not be disposed of in household waste. If crushed in a garbage truck, they can generate sparks and cause fires. Users should take old batteries to an authorized electronic waste collection point or recycling facility.
Conclude
While not common, the risk of fire and explosion from power banks is entirely possible if low-quality products are used or if they are used incorrectly. Most incidents stem from a lack of control over the power supply, the removal of protective components, and the habit of charging overnight for extended periods.
Choose products from MyMyTechnology A reputable power bank manufacturer in Vietnam, with rigorous quality control and comprehensive protection circuits, is key to ensuring safety. Safety, stability, good temperature control, and long-lasting durability are crucial criteria when choosing a power bank in today's technological age.
