Its safe to assume that your phone won’t die until you absolutely need to make a call, send a text, or pull up a map on Google. Backup battery packs are nothing new. They’re good for a quick recharge of your phone, usually only once. The JUMP by Native Union is smarter, literally. Featuring a compact, lightweight design, the JUMP is outfitted with 800mAh, good for an extra 3 hours and 50 minutes of talk time when you’re nowhere near an outlet. What separates the JUMP from other external battery packs is its trademarked AutoCharge system that detects when your smartphone’s battery is full and redirects the extra power to charge its own batteries.
