KITEURAD 65W Round Tip Charger for Lenovo Ideapad

KITEURAD 65W Round Tip Charger is a direct replacement power adapter for many Lenovo Ideapad, Flex and V-series laptops using the 4.0 x 1.7mm round plug.

This compact 65W AC adapter supplies 20V at 3.25A through a 4.0 x 1.7mm round tip and is built to match the power and connector type used on a wide range of Lenovo Ideapad, Flex and V-series notebooks. It supports global AC input (100–240V~50/60Hz), includes upgraded internal protection circuitry to reduce risk of overcurrent or short circuit, and is designed as a reliable replacement for original Lenovo chargers that share the same barrel connector and voltage specification.

Which Lenovo laptop models will this charger work with?

The charger is compatible with many Ideapad, Flex and V-series models that accept a 4.0 x 1.7mm round plug and 20V supply. Check your laptop’s required voltage/current and connector size before buying to ensure compatibility.

• Compatible with Ideapad series: Ideapad 3/5/1, Flex 3/4/5/6, and specific model numbers like 1-14IGL7, 3-15ITL6, 5-14ITL05.
• Works with V-series business laptops including V14, V15, V17 variants (V14-IGL, V15-IWL, V17-ITL, etc.).
• Also fits earlier Ideapad families such as 100/110/120/130/300/310/320/330 and S-series variants that use the round barrel connector.

How does the 65W adapter protect my laptop and battery?

KITEURAD built this adapter with upgraded internal monitoring to reduce risks associated with charging. The adapter includes overcurrent, short-circuit and overcharge protections that work with the laptop’s internal power management to keep charging stable.

• Upgraded chip improves voltage stability during charge cycles.
• Protection against overcurrent and short circuits for safer operation.
• Engineered to match factory power output (20V/3.25A) for compatible Lenovo models.

Will this 65W charger power laptops that originally used 45W adapters?

Yes — the adapter can physically power some Lenovo laptops rated for 45W if they share the same 20V and 4.0 x 1.7mm connector. However, always verify the original adapter’s voltage/current rating before substituting to avoid mismatches.

• Output: 20V / 3.25A (65W) but compatible with some 20V/2.25A (45W) models.
• Physical connector size is 4.0 x 1.7mm — confirm your laptop’s plug dimensions.
• Using higher-wattage adapters is generally safe when voltage matches and polarity is correct.

What can I expect from build quality and carrying convenience?

The adapter is compact and lightweight for travel, with a durable housing and strain-relieved cable ends to withstand daily use. KITEURAD emphasizes tested components and quality checks to reduce the chance of premature failure.

• Compact AC adapter brick suitable for backpacks and briefcases.
• Reinforced cable joints to resist fraying and bending stress.
• Passed manufacturer quality inspections for stable output and safety.
