If your iPhone's battery is running low and you don't have your charger handy, a case with a built-in battery can be a blessing. This is especially true if a clunky external battery pack that you have to plug into your phone sounds cumbersome. One option is Mophie's Juice Pack Plus, which has been around in one form or another for years. This particular model features a 3,300mAh battery inside its hard-shell case, which promises 120 percent more battery power. (Mophie also recently released a wireless charging case, which you can learn more about in the video below.)

Mophie Juice Pack Plus for iPhone 6/6S

The Good

The Mophie Juice Pack Plus more than doubles your iPhone's battery life. An indicator light helps you keep tabs on power levels, and its burly plastic construction protects against drops.

The Bad

The case is pricey and its matte finish attracts fingerprints.

The Bottom Line

Mophie's backup battery case remains one of the best in the biz, but it's pricier than others, so consider it an investment.

At $119.95 and £109.95 (or about AU$167) the Mophie Juice Pack Plus is pricier than its competitors like Incipio, Trianium and Anker (which fall between $60-80). But it's a good buy for the person who cares tremendously about effortlessly keeping the phone powered up and who doesn't mind carrying extra bulk.

A sliding toggle switch gets the case charging when your iPhone's power starts to dip; indicator lights on the back of Mophie's slide-on case help you keep tabs on how much power it has left. Since the Juice Pack Plus adds extra bulk, Mophie includes a short headphone jack extension in case your pair of headphones don't fit.

There's also a Micro-USB charging cable, which you use to charge the case. That means your iPhone's eight-pin Lightning charger won't work, which is a common case for third-party battery cases (if you're adamant on using only one cable, Apple's own battery case uses the Lightning port).

It took about 50 minutes for the case to charge an empty iPhone 6 50 percent, and a little over 2 hours to fully charge, with a little power left over.

Pleasantly, the case didn't obstruct the iPhone's audio or silent toggle, though its matte coating attracted fingerprints and smears. If you don't see yourself going through extra-long stretches without charging, you might be fine with a less expensive, lower-capacity charging case or small external power brick. But if you want a charger you don't have to worry about, the Mophie Juice Pack Plus is a reliable option that will last you days.
