Very few iPhone battery cases seem to offer removable batteries anymore, so Refuel Invictus for iPhone 6 ($100) certainly fills a void. Refuel Invictus (also referred to as Mojo Refuel Invictus) includes a thin 3200 mAh battery, which can be swapped out. iBattz sells a charger/power bank kit ($30) separately — it includes a battery and a charger for said battery. The case itself offers coverage for the sleep/wake button and volume controls, and comes in silver, space gray, or gold to match the color of an iPhone 6.

Refuel Invictus uses a two piece design. A back shell can be removed to install an iPhone 6, and it’s also how you get to the battery. The thin battery can be swapped out in a matter of seconds. It’s a clever design that doesn’t add much bulk. A power button for recharging can be found on the bottom of the case next to the headphone port. The micro-USB port is located next to the speaker port, and a thin LCD strip on the back of the case shows how much power remains.


The design is thoughtful enough, but where Refuel Invictus really wows is with its battery performance. The case gave our iPhone 6 a full charge in 2:09. And while iBattz claims the case can offer 120 percent extra power, we found it bested those marks, as Refuel Invictus delivered another 29 percent charge after a partial depletion, for a total of 129 percent.


We’ve seen a few great battery cases so far for iPhone 6, and this effort from iBattz joins their ranks. Though it’s a bit more expensive than some of those options, Refuel Invictus is a solid case with excellent battery performance, and the ability to swap in another fully charged battery for an extra $30 is a big bonus. Some users who rely on a heavier battery pack to get their iPhone 6 through a day — or two — might be better served using Refuel Invictus.
