SLE-TECH 135W 20V 6.75A Laptop Power Adapter

SLE-TECH 135W AC power adapter is a high-capacity replacement charger designed to power and charge compatible Lenovo IdeaPad and Z-series laptops reliably.

This compact replacement adapter supplies 20V at 6.75A (135W) and is built to match the power profile of several Lenovo OEM part numbers so you can restore full charging performance without buying a factory charger. It includes the AC power cord and a robust circuit design that adds overcurrent, overvoltage, overload, temperature and short-circuit protection. Note: the adapter is intended for use where mains voltage is 100–120V; for other regional voltages use a local-specified charger.

Which Lenovo models and part numbers will this charger work with?

This SLE-TECH adapter is compatible with many IdeaPad and Z-series laptops that originally shipped with a 135W supply. It matches a range of Lenovo P/Ns and model variants, making it a convenient swap for lost or damaged OEM chargers.

How does the adapter protect my laptop and battery?

The adapter contains protective circuitry to reduce the risk of damage from electrical faults and heat. These safeguards help the charger shut down or limit output during abnormal conditions, improving safety during everyday use.

• Overcurrent protection prevents excessive current draw that could stress components.
• Overvoltage and short-circuit protection guard the laptop from harmful spikes.
• Thermal and overload safeguards reduce risk from overheating under heavy loads.

What are the electrical specifications and regional usage notes?

Output rating and input range determine whether the adapter is suitable for your environment. The unit is built for mains rated 100–120V at 50–60Hz; using it on other mains voltages without a proper converter is not recommended.

• Output: 20V DC at 6.75A, 135W total power.
• Backward compatible with lower-watt systems (65W and 90W equivalents referenced for compatibility checks).
• Input: 100V–120V, 50–60Hz — intended primarily for domestic use in supported regions.

Who is this for? This charger is for Lenovo owners who need a reliable, high-power replacement for IdeaPad Y and Z-series laptops or for technicians and refurbishers stocking compatible power supplies. Choose this SLE-TECH adapter if your laptop requires a 20V/6.75A 135W input and you operate in regions with 100–120V mains. If your local mains voltage differs, select a regionally rated charger to ensure safe operation.
