To ensure safety, you should choose reputable backup battery chargers (despite higher prices).
Circuit design is not good
In addition to the quality of the rechargeable battery is not guaranteed, the poor circuit board design is also a cause that can cause backup charger to explode. Circuit board affects many factors, related to the performance and safety of backup batteries.
If designed well, cases such as overvoltage, overheating or short circuit on the charger will not occur and vice versa circuit design that does not conform to battery safety standards may increase the risk of explosion.
Currently, reputable manufacturers have integrated chips to automatically disconnect the current when fully charged. But with cheap batteries of 200,000 - 300,000 dong, there are not many safety features.
