Charger Compatible with Lenovo Laptop Computer 65W 45W Round Tip Power Supply AC Adapter

Key specs and what they mean for compatibility

This charger is built around a 20V output with two power levels:

• 65W mode: 20V at up to 3.25A.
• 45W mode: 20V at up to 2.25A.

It also supports 110-240V input at 50/60Hz, which is useful if you travel or live in regions with different mains voltages. The connector type is listed as round tip (Lenovo-style proprietary connector), so your laptop must use that physical plug.

Which Lenovo models it’s intended for

It’s marketed for a range of Lenovo systems, including several IdeaPad and Yoga models, plus certain ThinkPad configurations. It lists support for models such as:

• Yoga 710 (examples listed include Yoga 710-11ISK, Yoga 710-11IKB, Yoga 710-14ISK, Yoga 710-15ISK, Yoga 710-14IKB, Yoga 710-15IKB)
• IdeaPad 330 series (examples listed include 330-14AST, 330-15ARR, 330-17AST, and related 330 variants)
• IdeaPad 530S series (examples listed include 530S-14ARR, 530S-14IKB, 530S-15IKB)
• Additional Lenovo part-number references are included for specific original adapters

If your laptop model is not an exact match on the compatibility list, the safe approach is to verify both the round-tip connector and the required power wattage range for your exact device.

Ports, portability, and daily usability

Designed as a travel-friendly AC adapter, it’s intended to be easy to pack. The listing emphasizes a compact footprint and a weight under 5 lbs (shipping-weight scale not provided here, but the intent is clearly portability). For daily use, buyers commonly mention practical cable length and that it charges quickly once connected, which matters if you move around your workspace or want more reach from the outlet.

Pros and cons (expanded)

When this charger is a good fit

• You need a replacement Lenovo round-tip charger for a system that supports 45W/65W levels.
• You want travel compatibility thanks to the 110-240V input range.
• You prefer an adapter that includes multiple safety protections (short circuit, overcurrent, overvoltage, internal overheating protection are listed).
• You’re looking for a budget-friendly alternative to a factory charger, and the connector matches your laptop.

When you should look elsewhere

• Your Lenovo laptop uses a different connector type (for example, USB-C charging or a different barrel size style). This is not a substitute if the plug does not match.
• Your laptop requires a specific wattage that is not supported by the charger’s intended output (45W vs 65W). Check your laptop’s original adapter label or the device requirements before ordering.
• You need detailed proof of long-term durability. The available snippets confirm basic working performance, but they do not provide extensive performance history over many years.

Safety and build quality, what’s covered

The charger includes described safety mechanisms such as protection against short circuiting, overvoltage, overcurrent, and internal overheating. It also claims compliance with energy efficiency standards (DOE Level VI is mentioned) and includes an ETL specification marker. As with any replacement adapter, the best practice is to ensure the wattage and connector style match your laptop before regular use.

Price and availability

This is positioned as an affordable replacement charger, with the current price shown in the product listing and availability marked as in stock. If you’re comparing options, focus less on the brand name and more on ensuring the correct round-tip connector and 20V output with the appropriate wattage for your Lenovo model.

Verdict

If you have a Lenovo laptop that uses a round-tip adapter and needs 45W or 65W, this charger is a practical replacement choice. The strongest selling points are the dual-power output design, travel-ready input voltage, and buyer feedback that it fits and charges as expected. Just double-check your connector and your laptop’s power needs before purchasing, because the wrong plug or wattage can make any replacement charger a non-starter.
