How to Know if a Charging Cable Is Safe to Use?

In our daily life, a charging cable may look like a simple accessory — but it’s actually a critical safety component for both you and your devices. A low-quality cable not only shortens your phone’s lifespan but can also cause overheating, sparks, or even fires.

So, how can you tell if a charging cable is safe to use?

Let’s explore this through a real test conducted by LITO Lab.

LITO Lab Test: LD02 Silicone Cable vs. Regular Cable

To demonstrate the difference between a safe and unsafe charging cable, our team at LITO Lab performed a real safety comparison test.

Test Equipment:

LITO LD02 Silicone Charging Cable

Regular charging cable

Lighter and pliers

We started by cutting open both cables to expose the metal cores.

At first glance, the inner wires look almost identical — but the difference becomes clear under fire.

The Fire Test

When exposed to flame:

Regular Cable:

The wire core quickly melted, produced sparks, and even emitted a burning smell. This indicates that it’s made of copper-clad aluminum, a cheap and unsafe material that has a low melting point and poor conductivity.

LITO LD02 Silicone Cable:

The wire core only turned red and oxidized after being burned at high temperature — it didn’t melt or spark. That’s because the LD02 uses pure oxygen-free copper, a stable material with high conductivity and a much higher melting point.

Why Copper-Clad Aluminum Is Dangerous

Cables made with copper-clad aluminum (CCA) are cheaper to produce, but they’re also more likely to overheat during use.

When connected to high-value devices, a CCA cable can easily become a hidden time bomb, posing risks of short circuits, data loss, or even fire.

LITO’s Commitment to Safety

At LITO, we believe that safety should never be compromised for cost.

That’s why every LITO LD02 Silicone Charging Cable is built with:

High-purity oxygen-free copper core for fast, stable charging

Soft silicone insulation for flexibility and durability

Certified safety standards (CE) to protect your devices and data

Your phone, tablet, or laptop deserves a cable that’s not just fast — but truly safe.

Conclusion

A safe charging cable should:

Use pure copper cores.

Have proper insulation to resist high and low temperatures.

Be certified for safety (like CE or RoHS).

If your cable melts or sparks under stress, it’s not safe.

Choose reliability. Choose safety. Choose LITO LD02 Silicone Charging Cable.
