Review: Mophie's Juice Pack Reserve & Power Reserve Offer Power in Small Packages

Back in September, Mophie launched two brand-new battery products, the Juice Pack Reserve, a $59.95 battery case for the iPhone 6 and 6s, and the Power Reserve 1X, a small $34.95 external battery for smartphones and wearables. I have been testing both for the past two weeks in regular daily use and at a wedding, an environment that tends to be more smartphone-intensive than a typical day.

Mophie says the Juice Pack Reserve is the most compact battery case it's ever created, adding just 0.3 inches of thickness and 75 grams of weight to the iPhone 6 or 6s. In my testing, I found that Mophie's claim that the case is in a form factor that "you'll barely notice" is mostly true, although with a caveat. Its soft-touch back provided a comfortable and easy-to-grasp grip despite feeling noticeably more dense. However, the case's lower lip, where the speaker grille resides and the case plugs into the iPhone, is far more noticeable and users not accustomed to the extra length will have to spend some time acclimating to it when scrolling or typing.

The case's extra mass was not a hindrance when attemtping to quickly capture moments at the wedding though, as it slipped in and out of tuxedo pockets fairly easily. In fact, the in-pocket feel of the case was barely noticeable in tuxedo pants, even during more intensive activites like dancing. The extra mass of the case is, however, more obvious visually. In more regular daily use, the case was even less of a hindrance.

Mophie claims the Juice Pack Reserve will provide an additional 60 percent charge to an iPhone 6 or 6s, with the latter carrying a 1,840 mAh battery. This claim was actually conservative in my testing, with an iPhone 6, as I was able to consistently get a full charge from the case. For example, I was able to go from 10 percent to 100 perfect battery in just about two hours and six minutes and then 4 percent to 93 percent in about the same time.

The back of the Juice Pack Reserve features four LEDs that indicate the case's battery level next to a small button. When you hold this button down for a couple of seconds, it turns on the case and begins to charge the phone. The case was also able to easily get me through a full 14-hour day of battery-intensive Facebooking, Snapchatting, video recording, and photo taking while using the battery pack on and off during the wedding.

The rest of the case functioned without much trouble. The pass-through volume and power buttons are easy to use and reliable, the speaker holes generated no noticeable dip in audio quality, and the slot for the headphone jack was not an impediment. However, the cutout for the mute switch did make access a bit more difficult than without the case. The pass-through microUSB charger for the case's battery also worked well, intelligently sensing when it needed to charge the case versus the phone.

The smaller and more compact Power Reserve 1X, which houses a 2,600mAh battery in its soft-touch case, comes with both a single USB and a microUSB port. The microUSB port is for charging the battery pack while the USB port is to charge smartphones and wearables. Of course, users will have to provide their own charging cables.

Like its larger cousin, the Power Reserve was able to provide a full charge to my iPhone 6 in about two hours. It too has four LEDs indicating its power level next to a small button. With its larger battery capacity compared to the Juice Pack Reserve, the Power Reserve was able to provide a total of one and a half full charges to an iPhone 6. Additionally, the small button on the Power Reserve is only used to view the battery pack's power level, as devices plugged into it automatically start charging.

Mophie says the Power Reserve uses "Charge Vault" technology and digital power management to hold its charge while also intelligently detecting the device its plugged into to adjust charging speed accordingly. In my testing, these claims appear to be true. I did not use the device for a week and then came back to it, pressed the power indicator button and found that it still had a full charge.

Carrying around the Power Reserve is a fairly easy endeavor, as the actual battery pack easily slips into pockets and it's equally easy to forget about. However, having to carry around a USB charging cable for your device makes the entire thing a little less practical. It is worth noting, however, that at the wedding I was able to easily share a charge with several other iPhone users who needed it.

Mophie says the Power Reserve 1X also works for wearables, in my case an Apple Watch, but in practice it feels a little silly. Not only do you have to take off your wearable to charge it, but you have to carry around the Apple Watch's charging cable, which is highly impractical and unwieldy, particularly if you're using the 2-meter cable that comes with the watch. If you need this device to charge your Apple Watch on the go, it would be wise to find a shorter charging cable.

Both the Power Reserve and Juice Pack Reserve did experience rare hiccups when testing, although for the most part they didn't significantly impact overall usability. For instance, in one case my iPhone battery displayed a 10 percent charge while being charged by the Juice Pack, but when the charge case was turned off the phone switched to 1 percent.

The Juice Pack Reserve is a good recommendation for those who want the convenience of a battery case without too much of the extra mass. It's also a very good option for when you need extra power during special events, like a wedding or reunion or even a vacation. The smaller Power Reserve is a little more difficult to recommend, however. While it works well and is largely convenient to carry around for iPhone users who need to share charges in a group environment, there are cheaper alternatives on the market that provide more charge than it can.

Both the Juice Pack Reserve and Power Reserve 1X are available in white, black, purple, blue, and pink and are available on Mophie's website.

If you feel the need an extra battery like this from iPhone 6S, might as well get the iPhone 6S Plus. That extra weight and thickness you put in there, it's better to have a bigger screen and bigger battery. IMHO.

I play a real-time augmented reality game called "Ingress ('https://www.ingress.com')"*, which has you go out and walk around to "capture" your neighborhood (plus, as far as you want to go - it covers the whole world). The game eats battery power, especially when you're out walking around for many hours. ALL of the folks who play for any length of time end up getting external batteries. Probably half the players use Anker batteries, they seem to be the most popular (though I've seen numerous other brands, often based on what Amazon has on discount at any given time). Out of hundreds of players I've met, I think _one_ person had a Mophie case. When folks ask for battery recommendations on the forums, Anker gets recommended all the time. Mophie never does. Yet it feels to me like MacRumors reviews every new Mophie battery, but very few others.

(For the folks wondering why people "aren't smart enough to remember to charge their phone overnight" - this type of use has people sometimes using their phone's full charge two or three times over in a single day. Can't exactly stop for an hour or two to recharge. So, we just plug in the external battery and continue to play while the phone is recharging. The game is making continual use of the CPU, GPU, GPS, cellular radio, screen, etc. - like I said, it eats batteries... but it's really fun.)

Currently you can get an "Anker PowerCore+ mini", about the same size as the "Mophie Power Reserve 1X", but containing a 3350mAh Panasonic Li-ion battery (vs. 2600?), from Amazon for $9.99. The Anker has an anodized aluminum cylindrical case and one battery-level LED (all their larger models have more), while the Mophie has a box-shaped soft-touch case (what are they using the extra space for? the battery inside is almost certainly the same size 18650 Li-ion cell), and four battery-level LEDs. They both have a check-the-battery button, a USB port for charging your phone/device, and a Micro-USB port for charging the battery itself. They both have circuitry for determining what kind of device is attached and delivering the fastest possible charge to it (this circuitry has been one of Anker's selling points for a long time, but it's the first time I've heard of Mophie using it). It feels like Mophie is venturing away from their battery/case/sled product line, and into Anker's territory (external plug-in batteries), and isn't doing as good a job. Oh, but they are charging three times as much. Hmm.

(FWIW, my personal favorite is an "Anker PowerCore+ 10050", with a bit over 10kmAh, in a little jogger's pouch on my belt - currently goes for about $33 on Amazon.)

*: ( Available for iOS and Android. Completely free, it only costs all your free time [and some of your data plan]. You can play as much or as little as you want, and it will help you learn interesting things about your neighborhood - parks you didn't know were there and such. Great for getting exercise, having fun, and meeting new people. if you try it, join the green team, we have more fun than the blue team. )

I won't deal with micro USB ever again.

I MIGHT consider if it charged with USB C.


Design fail.

anker is much better priced and lasts just as long.. i don't work for them, just better bang for the buck..
and is the same price. haven't we seen this before.. oh yea.. ALL OVER CHINA. had a mophie for awhile, then switched it for my business and travel - I can't afford to spend what they are charging.. get it? . . have an anker now and no problems.. also the mophie case makes my phone so thick.. i am surprised apple lets them get away with the size they make these things.- i thought it was a race to be thinnest.. this defeats the purpose, doesn't it?
