What Does mAh Mean?
Nearly all batteries include a standard USB-A port (output). This is for plugging in USB-A-to-micro-USB, USB-A-to-Lightning, or USB-A-to-USB-C cables for charging your iPhone or Android device. Larger batteries with higher capacities might include a multitude of ports to support input and multiple outputs at the same time. You may see two USB-A and two USB-C ports, for example, though micro USB ports are becoming less common. The PowerAdd Slim 2 is as basic as power banks get, with just a micro-USB input, a USB-A output and no support for any fast-charging standards. What’s more, it’s slow. The USB-A output is specified as 10W, but in our tests we measured the output at between 7W and 9W depending on the phone. A 15-minute charge only raised the level on our test smartphone by 7%.

Avoid letting depleting the battery to 0% on a constant basis. Ideally, charge your power bank before it drops under 10%The most important thing to do is to match the battery’s output to your phone’s input. For example, if you have an iPhone, be sure the battery has its own Lightning connector or supports USB-A-to-Lightning or USB-C-to-Lightning cables.
Generally speaking, you charge the battery itself via micro USB or USB-C (input). Some batteries charge faster than others and USB-C charges much faster than micro USB. Pre-charge level: If you charge your power bank when it’s 20% full, it will obviously take less time than charging it from 0%.
