Need more power on longer trips?
Just double-press to activate Smart Efficiency Mode — giving you up to 30% more usable energy compared to Fast Charge.
That means instead of 2 full charges, your iPhone 15 Pro gets up to 2.6 charges — that’s 0.5 more than most power banks. (*Tested by Flextail Lab)
When Smart Mode is active, the indicator light turns 🟠 orange, so you can easily tell the difference at a glance.

USB-C Lanyard Cable
Doubles as a strap — to secure Zero Power to your backpack or harness, and always within reach when you need it.
