As everyone knows,Phones get faster every year, but the more powerful they become the less their batteries can keep everything going. And, of course, all batteries will degrade over time. If you need extra battery power for your Smartphone, tablet or other USB-powered device, you need a fast wall charger.

The industry standard for energy efficiency is between 60- and 70 percent, and if it doesn't expressly state otherwise on the packaging this is likely what you'll get. But some of the best power banks can offer as high as 90 percent energy efficiency, which equates to more full charges for your phone.

Typically you will need to carry a Micro-USB cable to charge your power bank, and potentially another cable for charging your phone if it doesn't use the Micro-USB connection to charge. Some power banks come with carry cables to ease this requirement; others might feature built-in cables and Micro-USB- to Lightning adaptors so all you need throw in your bag is the power bank itself.

Nearly all power banks use a series of  LEDs to show you how much power remains in the device. This is fine for smaller-capacity devices, but when each LED represents two- to three full charges for your phone it can be difficult to see exactly where you are.
