Safety: Keep the enclosure closed. Never bridge output terminals, bypass protective cutoffs or probe the internal battery/inverter. Disconnect external devices before inspecting plugs. Stop if a connector is melted, wet or physically damaged.
Applies to this exact equipment
AC180 only. Confirm the AC180 nameplate and regional AC outlet voltage; AC180P/AC180T specifications must not be substituted. The error names here are from the AC180 User Manual, §5.2.
Version check: Check AC180 versus AC180P: ratings, wiring and error-code tables may differ.

01
12V car outlet stops and E065 appears
HOW TO CHECK & CORRECT THIS CAUSE
- Unplug all accessories from the cigarette-lighter port, turn DC output off, inspect for conductive debris and damaged device plug, and use a known-good device within the port's rating.
How to tell it is fixed: DC output recovers and E065 remains clear.
02
Code returns only with one compressor/adapter
HOW TO CHECK & CORRECT THIS CAUSE
- That appliance or cord is drawing too much current or shorted.
- Replace the defective adapter or use a suitable higher-rated external supply, not a larger fuse or bypass.
How to tell it is fixed: Other correctly rated DC devices run normally.
03
E065 with port completely empty
HOW TO CHECK & CORRECT THIS CAUSE
- Stop using DC output and have DC socket/power electronics examined by BLUETTI.
- Never insert metal test probes into a live socket casually.
How to tell it is fixed: Normal protected 12V output after service.
