Ultra-Slim Battery Case

The Mophie Juice Pack Access is a protective case with a built-in battery designed specifically for the Apple iPhone 11 Pro Max. It extends the life of your iPhone while maintaining full access to its ports. The on-demand battery activates with a push of a button to top off the phone when needed. Users can send more messages or stream more video without worrying about battery levels.

Passive Thermal Management

The ultra-slim profile adds minimal bulk while housing the internal battery cells. During normal charging operation, heat dissipates passively through the case material. No active cooling fans are present, ensuring completely silent operation. Power draw is managed internally to prioritise phone charging efficiency.

Wireless Charging Compatibility

The case supports wireless charging so both the case and iPhone can charge simultaneously on a compatible pad. Priority charging directs power to the phone first before replenishing the case battery. LED indicators display the current charge status of the case at the push of a button. Full port access allows wired headphones and data cables to connect without removing the case.

Questions about this item

How do I install the Mophie Juice Pack Access on my iPhone 11 Pro Max and what step do people miss?

Slide the iPhone 11 Pro Max into the case until it clicks into the Lightning connector, then press the button on the back to start charging; the step people miss is pressing that button to activate the on-demand battery.

What maintenance or replacement will the Mophie Juice Pack Access need later?

The built-in battery will lose capacity over repeated charge cycles and cannot be user-replaced, so the entire case must be swapped when it no longer holds enough power for daily use.

What limit appears first during sustained use of the Mophie Juice Pack Access?

The internal battery capacity sets the limit; once depleted the case stops supplying power and must be recharged before it can top off the iPhone 11 Pro Max again.
