1Built to take a beating

IP68 and IP69K ratings and MIL-STD-810H testing mean it shrugs off drops, dust and high-pressure jets. A bright LED light helps at night or when camping.

221,560 mAh, 66 W charging

The big battery lasts through outdoor work and long days. At 66 W it fills in 2 h 50 min, and 10 minutes gives about 3 hours of use. It can also charge other devices over OTG.

364 MP camera, dual 5G

It has a 64 MP rear and a 32 MP front camera, plus dual-SIM 5G, Wi-Fi 6, NFC, face and fingerprint unlock, and six satellite navigation systems.
