Frequently Asked Questions About Product
Please read ourfrequently asked questionsto find out more.
What devices can I repair with the HERZO HES4VA screwdriver?
The 20-in-1 bit set covers 8 categories including Phillips, flathead, Torx, hex, and more. It's ideal for phones (iPhone, Android), laptops, tablets, smartwatches, glasses, cameras, game consoles, and small electronics. The three torque modes (0.05-0.3 Nm electric, 0.3 Nm manual) handle everything from delicate circuit boards to stubborn laptop screws.
How long does the battery last, and how do I charge it?
The 350 mAh lithium-ion battery delivers approximately 400 screws per full charge (tested with standard 2.5×5 mm screws). Charging takes 2.5-3.5 hours via the included USB Type-C cable. Connect to any USB power adapter, power bank, or computer USB port.
What's the difference between the three torque modes?
- Low electric mode (0.05 Nm): For sensitive components like watch backs, phone screens, or fragile plastic housings
- High electric mode (0.3 Nm): For most everyday tasks like laptop panel screws, glasses hinges, or standard electronics
- Manual mode (0.3 Nm): For stubborn or over-tightened screws that need extra force, or when you prefer full manual control
Simply press the mode button to cycle through settings.
Are the bits compatible with other screwdrivers, and can I replace them?
Yes. The bits use a standard 4mm hex shank compatible with most precision screwdriver handles. All 20 bits are made from S2 hardened steel for durability. While they're designed for long life, replacement bits with the same 4mm hex specification can be purchased separately if needed. The magnetic chuck holds bits securely during use.
