The first item is the car charger. This one has a micro USB port like the last one and also includes a full size USB port so you can charge something else simultaneously. This has been designed to work with Android or Apple products, but an adapter is required for the latter one. The power output is high which means you'll recharge faster, and there's also circuit protection built in which means it stops charging your device when the battery is full. Anyone who has ever purchased one of the cheap rechargers can tell you how it has damaged their phones. I've made the pics clickable links to the mfg website for those of you wanting to read up on or see what else they sell.
This next item is for those times when I'm not driving around. For the game this allows me to wander freely for the day without having to stop and recharge once every few hours. In terms of full timing this can carry you through the night if you need to power a tablet, phone, or any other USB powered tech. I can conserve laptop battery power by not having to power the phone from it when being used as a portable wifi hotspot.
