What this adapter is and who it suits

This 65W AC adapter delivers 20V at 3.25A through a 4.0×1.7mm connector. It replaces the original charger for a wide range of Lenovo IdeaPad models across the 1, 100, 300, 500 and 700 series as well as C and D series laptops. Buyers who need a different connector size or a higher wattage unit should look elsewhere.

Behaviour under sustained load

The adapter accepts a universal 100-240V input at 50-60Hz and maintains a steady 65W output. It is certified to CE, FCC, RoHS and UL standards, indicating stable voltage regulation during continuous operation. The unit is designed to match the original power specifications without derating over time.

Thermals, noise and power draw

With no moving parts the adapter runs silently in normal use. Heat is dissipated through the enclosure surface while drawing up to 1.3A from the mains supply. The compact brick form factor keeps cable clutter low and operates within the thermal limits defined by its safety certifications.

Questions about this item

How warm does the 65 W brick get when it runs all day?

The adapter is rated for continuous 65 W output at 20 V 3.25 A with a 100-240 V input, so it stays within normal operating limits for a slim laptop charger under full load.

What must I already own to use this charger with my Lenovo IdeaPad?

You need a Lenovo IdeaPad model that accepts a 4.0×1.7 mm barrel plug and draws up to 65 W, such as the 110-15ISK, 320-15ABR, 330-15IGM, 330S-15IKB, S340-15IWL or any other model listed in the compatibility table.

Will this 65 W unit safely charge an older 45 W IdeaPad that uses the same 4.0×1.7 mm tip?

Yes — the adapter negotiates 20 V 3.25 A but will deliver only the current the laptop requests, so a 45 W system like the 100S-14IBR or 110S-11IBR charges normally without risk.
