In the power bank market, consumers are often attracted by factors such as capacity, appearance, and price, while ignoring the most core component – the battery. But did you know that inferior batteries may lead to serious problems such as false battery life, bulging and explosion, and shortened life?
Common problems with inferior batteries:
🔹 False capacity: Many low-end power banks claim 10000mAh, but the actual available power may be only 7000mAh or even lower.
🔹 Short life: The number of cycles of charge and discharge of inferior batteries may be less than 300 times, while that of A-grade batteries can reach more than 800 times.
🔹 Safety hazards: Some unqualified batteries are prone to bulging, fire, and even explosion in overcharge, short circuit, and high temperature environments.
How to choose high-quality batteries?
✅ Branded batteries: Choose well-known brands and avoid unbranded or recycled batteries.
✅ Complete testing: Regular suppliers will provide complete data such as capacity testing, overcurrent testing, and overtemperature testing.
✅ Battery certification: High-quality batteries will pass international certifications such as UN38.3, MSDS, and IEC62133 to ensure safety.
Whether it is corporate procurement or personal purchase, don’t just look at the price and ignore safety and durability. Although the cost of power banks using Class A batteries is slightly higher, they are safer, more durable, and their service life is increased by 2-3 times. In the long run, it is more cost-effective.
