Overview
An electric air tool from GX, model GX-E-CS4-I, with a 6.8 liter tank and 12 volt power draw, weighing 33.7 pounds. It carries a 4.4 star rating from 230 reviews and 50 units bought in the past month.
The 12 volt rating paired with a tank points toward a portable air compressor built to run from a vehicle outlet as well as household current, rather than a full shop compressor. Maximum PSI and CFM output are not stated here, so confirm those before relying on it for anything beyond light inflation tasks.
- 6.8 liter tank capacity
- 12 volt power source
- 33.7 pound total weight
- Corded electric operation
Who it's for
Fits buyers who need portable air for tires or small pneumatic accessories on the go. Not suited to continuous shop-air demands without a confirmed pressure output.
Strengths and trade-offs
Drawn from this product's published specifications.
- 6.8 liter tank capacity
- 12 volt power suits vehicle use
- Max PSI and CFM not listed
- 33.7 pound weight limits easy carrying
Performance notes
A 6.8 liter tank stores enough air for short bursts rather than sustained heavy use, refilling as needed through the motor. Running on 12 volts suggests flexibility between a vehicle power source and standard current, though the exact plug type is not specified.
