Drop Test

Overall Product Quality Inspection

Is the fan fitted with two or more well-balanced blades made from metal or other suitable material so as to be reasonably free from vibration? Yes
Are the bearings of good quality and lubricated appropriately for use? Yes
Is there an automatic shutdown mechanism when fan blades are impeded? No
Is the fan clearly marked with a standard nameplate? Serial number not provided
Notes About Nameplate No
Does the fan's packaging include appropriate information? Missing manufacturer name, trademark, gross weight, package dimension, precaution text, date of manufacture and country of manufacture. The model name on the package was inconsistent with that on the rating label.
Notes About Packaging No
Does the fan come with appropriate documentation? Only installation instructions were provided but missing user manual and warranty information
Notes About Documentation N/A
Are the fan blades appropriately guarded in accordance with Clause 20.101 of "IEC 60335-2-80: Household and similar electrical appliances. Safety. Particular requirements for fans."? No

Off-Grid Compatibility

Does the fan have its own low voltage disconnect (LVD) & reconnect (LVR) circuit or similar automatic shutdown mechanism to protect batteries from unintended drainage? No
Notes About LVD and LVR Product shut down automatically when the input voltage was reduced to 7.2 V.
Is the LVD/LVR/timer function adequately described in the user manual or product packaging? Can not be determined
