Charging case re-invented.
We know people rely on their iPhones to keep them connected, and sometimes need an extra charge to get them through those longer days. At tech21, we challenged ourselves to develop a truly safe battery solution, free from the problems that today's batteries bring. Using unique technology, specifically designed for maximum safety, the result is the world's first ultra safe battery case.
The world's first ultra safe charging case.
Traditional batteries emit heat, can leak toxic chemicals and even become flammable when damaged. Using Lithium Ceramic battery technology, Evo Endurance is the world's first ultra safe charging case, suffering from none of these problems.
What you love. For longer.
The 1800mAh Lithium Ceramic battery provides 60% extra charge at the touch of a button. That's more talk time, more internet browsing, more music and more video playback.
Not just safer protection. Slimmer protection.
Evo Endurance is the world's thinnest and lightest ultra-safe charging case. FlexShock™, a unique material which absorbs and dissipates shock away from your device when dropped, means the super slim Evo Endurance provides impact protection from drops of 2m / 6.6ft.
Unhindered user experience.
Evo Endurance is easy to install and charging starts at the touch of a button, while an elegant LED indicator let's you know how much charge is remaining. Comfortable and precise access to all ports and function buttons means uninterrupted use throughout your day.
Premium materials, precision manufacturing. Quality assurance. We have ultimate confidence in the performance of the Evo Endurance, however if your case becomes faulty during normal use in the first year, we'll replace it for free. Conditions apply.
