The iPad battery is fantastic because of its long lasting capabilities. However, the downside is that it can also take a very long time to charge an iPad 2. There are many iPad charger options including the USB iPad 2 charger, Griffin's PowerBlock iPad charger, the iPhone power adapter, and the basic iPad 2 charger. We did some research to find out which of these iPad chargers are the fastest at getting your battery up to 80% full. The reason we chose 80% in the iPad charger review is because the last 20% of charging goes slower in order to protect the battery's longevity.
The iPad 2 uses a lithium-polymer battery, which is also used in the iPhone, the Pod touch, and even Apple's MacBook line of laptops. In the iPad 2′s case, the 25 watt hour lithium-polymer battery fills up most of the space inside, which is why it can last for 10 hours of surfing, listening to music or watching videos... provided it's charged.
There's a lot of ways to recharge an iPad, USB-but the iPad is finicky. For a portable, it has high power requirements, high enough to cause problems for some people.Here's how to get it that way as fast as possible.
Apple includes a 10W USB to AC power adapter right in the iPad 2 box and this is the absolute fastest way to charge your iPad 2. Just plug your 30-pin Dock cable into your iPad, plug the USB connector into the adapter, and plug the adapter into a wall socket. Apple even sells an extended adapter if you need it.
USB Port

Sometimes one port might be better than another, for example many laptops have some USB ports that are independently powered and others that share power. Try different ports until you find the one that works best.
Some laptops, like Apple's MacBook Air which was designed to power an external DVD drive over USB, or the brand new MacBook Pros, have higher power USB ports that could charge faster.If your laptop has a high power USB port, that's what you'll want to use.
Car Adapters
If your car has a USB or AC port, follow the directions above and charge away. If you have a standard car port/cigarette lighter port, you'll need a car adapter. Not all car adapters support iPad so make sure you get one that states it works with iPad 2.
Battery packs
