Reliable power adapter for LENOVO laptops with 45 W output and 20 V / 2.25 A provides stable power and safe charging. It features a ferrite filter for a clean signal and comprehensive protections against overvoltage, overheating, overload, and short circuit, making it ideal for demanding users who need worry-free and comfortable work.
This high-quality power adapter is designed for LENOVO laptops and delivers a stable output of 45 W with parameters 20 V / 2.25 A. Thanks to the ferrite filter, it suppresses interference and ensures a stable current without fluctuations. The product undergoes strict quality control and meets CE, RoHS, and FCC certifications.
Safety comes first: integrated protections against overvoltage, overheating, overload, and short circuit protect your laptop and adapter during everyday use. Precise voltage output and quality components contribute to long service life and reliable operation.
- Temperature resistance – tests in low and high temperatures verify the stability of protection circuits and electrical parameters.
- Electrical tests – verification of correct electrical connections between all adapter components.
- Short-circuit and overvoltage tests – simulation of a short circuit and sudden voltage spike to verify the response of protection circuits.
- Final load test – hour-long continuous load verifies the stability and accuracy of the output voltage.
