THE GT4000S

The GT4000S also weighs 1Kg but measures 228mm in length, 100mm in width and 54mm in thickness (on/off and boost buttons are both on top).

Since this is an IP65 certified device all ports (jump starter, two USB-A, USB-C, DC) are located behind a rubber cover at the front.

The 400 lumen LED torch is placed at the rear of the unit.

Product specifications and error messages are all printed at the base.

As I mentioned before even though the A3 and GT4000S both have 3.2” LCD screens they are different with the one used in the GT4000S being easier to read under direct light.

Only the jumper cable attaches to the GT4000S when you need to start your car.

Since the GT4000S doesn’t come with a carrying/storage case in the bundle I strongly suggest ordering the hard EVA case from Gooloo seen above (provides even more protection and well, I think the GT4000S deserves it).
