45W USB C Laptop Charger Compatible with Lenovo - Compact 45W PD

In this review the 45W USB C Laptop Charger is evaluated as a compact, practical replacement adapter for a range of Lenovo Chromebooks and ThinkPad laptops. The bottom line: this charger is for users who need a reliable, standards-based USB-C power supply with 45W Power Delivery to charge midrange laptops and convertibles. It delivers consistent voltages and a broad compatibility list, making it a sensible spare or travel adapter for students, office workers, and anyone who wants a compact, interchangeable USB-C power solution.

Key Features

• 45W USB-C Power Delivery: Supplies up to 45 watts through the Type-C port so compatible laptops charge reliably and reach usable battery levels during light use.
• Wide input range: Accepts 100-240V 1.3A 50-60Hz input, making it suitable for international travel with the right plug adapter.
• Multiple output profiles: Supports 20V-2.25A, 15V-3A, 9V-2A and 5V-2A outputs so it negotiates correct voltages with many USB-C devices.
• Lenovo compatibility list: Mentioned compatibility with many Lenovo Yoga, Chromebook and ThinkPad models means users can replace several factory adapters with one charger.
• Safety protections: Built-in over voltage and short circuit protection plus CE, FCC and RoHS certification help protect devices and offer regulatory peace of mind.

Who It's For

This charger is ideal for owners of Lenovo Chromebooks like the c330, s330 and c340 series or ThinkPad models such as the T480/T580 family who need a compact, USB-C replacement adapter that supports Power Delivery. It also fits students and professionals who travel and want a single charger that covers laptops and smaller USB-C devices.

It is less suitable for users who require very high-wattage charging (for example gaming laptops or heavy workstation use) because it tops out at 45W, and buyers who need proprietary barrel connectors rather than USB-C should look for model-specific adapters instead.

Pros & Cons

Pros

• Good balance of power and portability with a 45W USB-C PD output that handles most ultrabooks and convertibles.
• Wide input voltage range makes it convenient for international use with a plug adapter.
• Multiple output voltages allow safe negotiation with a variety of devices and preserve battery health.
• Includes common safety protections and regulatory certifications for added confidence.

Cons

• Maximum 45W output means slower charging on higher-power laptops and may not sustain heavy workloads while charging.
