I’ve found my iPhone 5 battery typically lasts at least 2-3 days between charges on my slow days, but when I’m traveling or using my phone a lot, the battery can drain pretty quickly. The last thing you need is to find yourself with a dead phone while traveling, so a backup battery is a smart thing to carry in your EDC gear. These new Apple-certified battery extenders from iWALK could be just what you need for your iPhone 5. First up are the Link chargers for iPhone 5. The Link 1000i5 ($44.95) is a 1000mAh external lithium-ion battery that can give you up to 4 extra hours of talk time; the Link 1700i5 ($54.95) has 1700mAh for up to 6.5 extra hours of talk time; and the Link 2500i5 ($64.95) has 2500mAh for up to 10 extra hours of talk. Each of these Link batteries are available in black or white, and they provide 5V at 1A power for your iPhone 5 or 7th-gen iPod touch. If you prefer a case with a built-in battery, check out the Chameleon Lite case with a 2000mAh lithium-ion battery. You have easy access to all the iPhone 5′s ports and controls while it’s in the case, and you can sync to iTunes without removing the case. You can even charge the case and the iPhone 5 simultaneously. The Chameleon Lite case is available in silver or white for $69.95.
