USB Power Delivery is the fastest way to charge iPhone and Android devices

With the current generation of smartphones and their much faster processors and vivid, high-resolution displays, and always-on connectivity, demands on battery performance are now higher than ever.

You may have noticed that, while you are on the road, you're quickly running out of juice. If you have this problem, portable batteries and PD fast charger than what may have come in the box with your device may be the solution.

But not all portable batteries are the same, even though they might use similar Lithium Polymer (LiPo) and Lithium-Ion (Lion) cells for capacity and look very much alike. Plus, modern smartphone hardware from Apple and various Android manufacturers support faster-charging rates than what was previously supported.

If you use the charger that comes in the box of the current-generation iPhone hardware, or if you buy just any portable battery pack on the market, you're going to be disappointed. Ideally, you want to match your charger, battery, and even the charging cable to the optimal charging speeds that your device supports.
