The provide picture delineates the differences between two types of power banks. Overall, the safe power bank contains more protection features whereas the remaining uses low-quality materials or unused brand.
In the safe portable charger, it is equipped with qualified flame-resistant casing, preventing overheat or combustion. A protection circuit installed inside ensures the stable flow of electricity. Additionally, the power resource can effectively activate thanks to Li-ion battery cells . The packaging is also clearly branded, which indicates manufacturer reliability to users. Lastly, the item enhances convenience and safety by the input/output port properly labelled under the packaging.
In contrast, the risk of fire outbreak can not be prevented by the unsafe power bank, as it only owns a simple circuit board. Moreover, the materials, including batteries and the package, are unbranded, which raise concerns about its crediblity. Like the safe one, this also encompasses input/output port, but the absence of safety components make this port potentially hazardous during use
