How can I see how much battery power left?

When the battery level is below 20% in use, the indicator will rapidly blink red for 5 seconds.

When charging, the indicator will slowly blink red.

When fully charging, the indicator will become solid white.

What's the real torque of E1 Max?

E1 Max has 2 torque settings, the low torque 0.05 N.m and the high torque 0.2 N.m can be adjusted through the rotary knob.

Twist to the LOCK SIGN, the gearbox will be locked, manual mode can be used at this time, max manual torque is 3 N.m

Relationship between the preset torque and speed.

Switching the torque does not affect the speed, but only affects the torque of the screwdriver on the screw.

E1 Max unloaded speed is constant at 200 rpm. The sound produced by rotation has nothing to do with the torque.

What are the applicable scenarios?

E1 Max is only suitable for the repair of Precision Instruments, such as phones, drones, laptops, steamdeck, watch, etc.

If you need something with larger torque, opt for our S1 Pro Electric Screwdriver.
