Review on BEETRO Electric Inflator Portable 4 72 16 54 by Mark Adlesh

PORTABLE ELECTRIC KEY: There are 4 key head sizes (17mm/19mm and 21mm/23mm), suitable for different wheels and vehicles. You can choose them according to your actual needs. While using the electric wrench, the thumb must hold the switch at all times and cannot be loosened until the nut is removed or tightened. NOTES: Use it on a flat surface. Do not use more than 3 tons. Start the car engine before operation, make sure there is enough electricity.
