How To Choosing The Right Power Bank?

Safety is the key to choosing the right Power Bank
The main component of a power bank is a lithium ion / lithium polymer battery. Although these types of batteries are commonly used, the safety of battery product is always the utmost concern. Power Bank safety can be addressed on two fronts:
1. Battery Quality Grade A is a general concept used to denote a very good quality battery. The real test is whether or not the battery has a UL Certification. Though all our power banks have many certifications, our most popular power bank batteries have passed the UL 1642 test which is a set of rigorous Electrical, Mechanical, Environmental, and Fire Exposure Tests. UL is the most widely accepted certification that denotes a battery's compliance with recognized safety requirements in North America.
2. Protective Circuitry The Protective Circuitry or PTC is considered a " Safety Valve". It protects the equipment, the charged device, and user. PTC prevents Internal and External Short Circuit, Abnormal Charge/Over Charge, forced Discharge, and more.

It's easy to reduce the costs of power banks by cutting out the cost of battery certifications and protective circuitry. But doing so creates a tangible risk to the safety of the power bank, the phone and other charged devices, and even harm the user.
