iPhone X road warriors with significant energy requirements need look no further. This slim brick from Mophie packs a 10,000mAh battery, making it sufficient to charge Apple's latest smartphone three and a half times over - perfect for when you're off the grid and away from a power outlet for a few days.
The Force PowerStation is Qi wireless compatible, so all you need to do is place your iPhone X on top of it while it's lying flat. It also supports pass-through charging, so if it's connected to a power source, your phone recharges first, then the brick recharges itself.
There's even a USB port for an additional device to plug in and get some extra juice on the side.
