Frequently Asked Questions (FAQ)

How does the Power Bank function work?

It's incredibly easy! Simply plug the included OTG converter into the P4's Type-C port, then plug your phone's charging cable into the converter. The massive 5000mAh battery inside the flashlight will immediately begin charging your electronic devices.

How do I lock the flashlight so it doesn't turn on in my pocket?

When the flashlight is off, press and hold the side switch for about 2 seconds. The orange LED indicator will flash quickly to confirm it is locked. To unlock it, quickly triple-click the switch.

Is the 21700 battery proprietary?

No. While the kit includes an excellent SPERAS 5000mAh 21700 battery, the P4 is compatible with standard high-drain 21700 lithium batteries, unlike some competitors that force you to buy expensive proprietary cells.

Does it get hot on Turbo mode?

Generating 4000 lumens creates heat. However, the P4 features an ITS (Intelligent Temperature Control System) that detects heat in real-time and smoothly adjusts the output to protect both the internal circuitry and the user's hands.
