Compatibility
Designed for notebooks and netbooks that use an 18-20V DC barrel input and draw up to 40W. Check that your original adapter is around 19V and 40W or less, and select the matching tip before use. It is not suitable for larger 65W+ laptops or for machines that charge only over USB-C Power Delivery.

87% Efficient, Energy Star
High 87% conversion efficiency with CEC and Energy Star Level V certification means less wasted energy and lower running heat.
 
Protected Circuitry

Frequently Asked Questions

Will the UNA-40 fit my notebook?
It suits notebooks and netbooks with an 18-20V DC barrel input drawing up to 40W, and includes six tips covering common brands. Compare your original plug and adapter rating against the included tips before ordering.
Is 40W enough for my laptop?
40W (19V / 2.1A) is aimed at netbooks and smaller notebooks. Larger or performance laptops that need 65W or more should use a higher-wattage adapter instead.
Does it work with USB-C laptops?
No. This is a barrel-tip charger. Laptops that charge only over USB-C Power Delivery require a dedicated USB-C PD adapter.
Singular Expert Insight
The UNA-40 is best understood as a lightweight 40W spare for netbooks and slim, low-power notebooks — its Energy Star efficiency and carrying case make it a neat travel option. If your laptop originally shipped with a 65W or 90W adapter, choose a higher-rated unit from our laptop power supplies range so the machine charges at full speed. Always match voltage and tip before first use.

Buyer's Guide

Buy it if
You need a light, efficient 40W spare for a netbook or smaller 18-20V laptop and want a carrying case and multiple tips.
Skip it if
Your laptop needs 65W or more, uses USB-C Power Delivery, or requires a voltage outside the 18-20V range — this 40W unit will not suit it.
Also consider
A 65W or 90W universal adapter for mainstream laptops, or a dedicated USB-C PD charger for modern ultrabooks.
