The Fanttik E1 MAX sometimes feels like it has no torque on the smallest screws: it starts the screw fine, then quits halfway through tightening, or simply refuses to drive a stubborn M1 in a MacBook chassis. This is not a battery problem. It is the auto-mode torque cap doing exactly what it was designed to do.
Symptom Quick Check
- Motor spins freely, then cuts out mid-tightening — auto mode torque cap engaged. Switch to manual mode.
- Motor spins, screw barely advances, lots of resistance — bit is wrong size, not a torque issue.
- Motor doesn't spin at all on the button press — battery, switch, or motor problem; check LED indicator first.
- Spins on the bench but stops the moment the bit touches the screw — auto mode set too low. Increase torque setting.
Most Common Cause
The E1 MAX runs at 0.05 N·m on low torque and 0.2 N·m on high torque in auto mode. Manual mode pushes up to 3 N·m. The auto-mode caps are intentionally conservative because the unit is sold for precision work — iPhone screws, MacBook bottom plates, PS5 fan repairs — where over-torque strips the screw head. A stubborn screw that resists at 0.2 N·m is real-world; the E1 MAX is doing its job by stopping.
Step-by-Step Fix
- Verify the bit matches the screw head exactly. A PH00 in a #0 Phillips slot will cam out under any torque. iPhone bottom screws use Pentalobe P2, not Phillips.
- Set the auto-mode torque to high (0.2 N·m). The low setting is for camera lens screws and similar fragile work.
- If the screw still resists, switch to manual mode and finish the last quarter-turn at the higher manual torque ceiling.
- Hold the E1 MAX in line with the screw axis. Off-axis force is what most owners feel as "loss of power" — the bit is slipping rather than the motor failing.
- For very stubborn screws, use the E1 MAX to break loose, then finish by hand with the bit still on the unit's magnetic holder. This avoids over-torque on the seat.
- If the LED ring dims during the cut-out moment, that is auto mode signaling the trip — not a low battery. Verify by checking battery icon between attempts.
When to Contact Support / Warranty
The E1 MAX is operating correctly when auto mode cuts at the rated torque. Open a warranty ticket only if:
- Manual mode also fails to drive screws that you can drive by hand with a standard precision screwdriver.
- The motor stops on the very first screw of a fresh charge, with the correct bit, in manual mode.
- The unit makes a grinding noise on every attempt.
Contact Fanttik support with the screw spec, bit number used, and the mode (auto vs manual) at the time of failure.

FAQ
Q: Why does my E1 MAX feel weaker than my old Wowstick?
A: Auto-mode torque caps differ between brands. The E1 MAX manual mode reaches 3 N·m, which matches or exceeds most precision drivers in its class.
Q: Will manual mode strip my iPhone screw?
A: It can, if you hold the trigger after the screw is seated. Use manual mode for the last quarter-turn only, then release.
Q: Does the bit size matter for torque?
A: Yes. A correctly-fitted bit transfers full torque; a wrong-size bit slips and feels like motor failure.
Q: Is there a way to lock manual mode at a specific torque?
A: No, manual mode is variable. Use trigger pressure to modulate the speed and learn the feel for each device.
