Installation
1. Charge initiale
Before first use, fully charge the air compressor. Connect the provided Type-C charging cable to the charging port on the device and the other end to a 5V/3A USB power adapter (not included). The battery indicator on the display will show charging progress. A full charge typically takes approximately 3.5 hours.
2. Raccordement du tuyau d'air
The air hose is stored by being locked into the device. To use, pull the air hose out of its storage slot. This action will automatically power on the device. Connect the appropriate valve adapter (Schrader, Presta, or needle valve) to the end of the air hose, depending on the item you intend to inflate.

Mode d'emploi
1. Mise sous/hors tension
- Mise sous tension : Pull the air hose out of its storage slot. The device will automatically power on and display the current pressure.
- Éteindre: Push the air hose back into its storage slot. The device will automatically power off.
2. Comprendre l'affichage
The large LED display shows the current pressure, selected mode, and battery level. You can switch between PSI and Bar units using the unit selection button.
