Stay in Touch - iConnected: Use AirPlay, iCloud, Apps, and More to Bring Your Apple Devices Together - page 146

TIP: Set your iOS device to show its battery charge, so you know how much is left with a quick
glance at its status bar. Turn on this display in the Settings app's General pane. Tap Usage and then
set the Battery Percentage switch to On, as Figure 6-15 shows.

You'll want both a wall charger and a car charger for your iOS devices. There are dozens of such
devices available, many for under $15. Compact ones are easier to carry and fit better in tight spaces
such as the power ports in some airplanes and airport lobbies. PowerGen , for example, makes inex-
pensive, compact, and stylish chargers.
Keep in mind that iPads use more power than iPhones and iPods to recharge, so be sure your
charger can charge your iPad — many can charge only iPhones and iPods. Look for chargers that out-
put at least 10W or 2.1A on at least one connector; that's what an iPad needs.
Also, be sure to get chargers that have at least two USB ports into which you plug in your iOS
devices' USB cables — that way, you can charge two devices at the same time from a single outlet.
After all, free outlets can be scarce in hotels and lobbies, plus many cars have just one cigarette-light-
er port in which to plug chargers.
If you travel with a MacBook, consider buying Twelve South's $35 PlugBug , which you piggyback
onto your Mac's power brick, so you use only one wall outlet to charge both your Mac and your iOS
device.
A convenient option for iPhone users is to use a battery and case combo to give your phone extra
power while still keeping it portable. Cases like the $100 Mophie Juice Pack allow you to effectively
double the life of your iPhone's battery while keeping it safe from drops and knocks. The Juice Pack
allows you to turn on and off charging, too, so you can use the charge from your phone first before
charging it with the case's rechargeable battery.
