Ultra-slim Qi2 power bank

The SolidSafe Air 5K delivers a 5000 mAh semi-solid-state battery in a 6.8 mm profile that sits flush against an iPhone 12 or later. Its titanium-reinforced shell resists dents while keeping weight to 116 grams. The 18.5 Wh capacity stays well within the 100 Wh airline carry-on limit.

Simple magnetic attachment

Qi2 certified wireless charging locks on at up to 15 W, while the USB-C port provides up to 20 W wired output. Both ports can run together at a combined 10 W wireless plus 5 W wired. Pass-through charging lets you replenish the power bank while it charges your phone. Built-in safeguards protect against overcharging, over-discharging, overcurrent and short circuits.

Check your device and cable

Wireless charging requires an iPhone 12 or newer with MagSafe-compatible alignment. For wired use you need a USB-C cable capable of the desired current. The power bank itself recharges via USB-C, so confirm you have a suitable charger and cable before ordering.

What comes with the Air 5K and what must I supply myself?

The box contains the 6.8 mm slim power bank with its built-in USB-C port; you will need to provide a USB-C cable and a USB-C power adapter for recharging the unit.

Which capacity should I choose for daily iPhone top-ups?

The 5000 mAh / 18.5 Wh cell gives roughly one full charge for most current iPhones and stays under the 100 Wh airline carry-on limit.
