Paired with the universe case, this battery lets you pack along some extra juice when heading off the grid for extended periods.
OtterBox PolarPro PowerPack Mobile Battery Pack is rated 4.0 out of 5 by 24.
Rated 4 out of 5 by Harry from no nonsenseI like it - extends life of my IPhone 7 battery to 20+hours (of how I use the phone) my only criticism is that the charging port is micro USB (not lightening) so I need one type of charging cable for the battery and a different one for my phone

Rated 1 out of 5 by David from Substandard productI have battery pack for my iPhone6s, but as we’re beyond product cycle, I thought I’d order a backup from Otter. This new improved pack has less than half the life of my existing pack that’s two years old. Totally lame.

Rated 1 out of 5 by KenT from Not what i expected. Battery is only 2100mahBattery is low amp hour rating 2100 so it only lasts 1/2 day and there is no otterjox option to get a stronger battery. I will be looking at other battery case options. Also the case is coated with a material that is rubbing off

Rated 2 out of 5 by MrEd58 from Not what I expected!I got this item because I get a lot of calls and make it easier to charge my phone while on the go. Well, after charging my phone one time, the back-up battery needs to be charged. Didn’t last long enough for a second around of charging.

Rated 3 out of 5 by CobraA1 from Hopefully betterBeen buying these batteries for a while. They never seem to last long. The latest one changed how it looks, let's hope they changed the internals as well.

Rated 4 out of 5 by DonkeyKong from A very good chargerI bought this just a week or two back and I'm very happy with the results. It charges my phone pretty well, although I'd like it to provide a larger charge.

Rated 4 out of 5 by Jeff from The case was a replacement for the Resurgence caseI received the case for free but I had to pay for the battery pack and since this was a replacement for the Resurgence otter box case I felt like I should not have had to pay for the battery pack
