This is what is referred to as, “total” power.Ī mobile phone with an advanced mobile operating system, usually with internet access, touchscreen interfaces, cameras, media players and the ability to run third-party apps.Ī mobile computer with a touchscreen display, circuitry and battery in a single, portable device, usually featuring pop-up, virtual keyboards for typing. a 2 x 1.2A and will charge two smartphones at 1.2A. Some multi-port power banks (aka portable chargers) will have fixed outputs on each port, e.g. a 2 x 1.7A will charge two smartphones at 1.2A each, or one tablet at 2.4A. Shared power banks will provide power where it’s needed, e.g. It describes the constant and average current that passes through the circuit. Short for ampere, this is a unit of current, not a unit of charge. a 2000 mAh battery will power a device drawing 100 mAh for 20 hours. It is based on how long a battery will last when power is drawn constantly, e.g. MAh stands for Milliamp Hours and quantifies the energy storage capacity. Batteries which pass such stringent testing will be more durable and offer improved assurances of overall safety and performance. While using batteries in extreme temperatures isn’t advised anywhere, it can be a good indicator of weaknesses in design and construction. Some battery packs consistently monitor charge states to prevent this from happening. High-performing batteries should not be overcharged or fully discharged to prolong their life expectancy. Like OCP, OVP protects both the battery pack and the connected device by keeping the voltage within recommended safety parameters to avoid damage. OCP prevents too much power going into the battery pack and the power going out to the connected equipment, protecting the delicate circuitry of both devices. More efficient battery packs will have a lower operating temperature, which wastes less energy, giving it longer life expectancy.

Safe battery packs should have undergone the following testing Rigorous testing and thorough investigation of product performance make your battery pack more likely to last longer, and less likely to harm you and your valuable electronics. THE IMPORTANCE OF QUALITY A robust quality assurance offers durability and peace of mind.
