Questions about this item

How much heat or noise does the 45 W adapter produce when it runs all day?

The adapter includes overheating protection and short-circuit protection, and it operates from a 100-240 V 50/60 Hz supply without a fan, so it stays cool and silent during continuous use.

What must I already own for the USB Square Yellow Tip connector to work with my laptop?

You need a Lenovo Yoga 2 11, 11S, 13 or 2 Pro 260, or a ThinkPad Helix 11.6 with i5-3337U, i5-3427U or i7-3667U, because the square yellow tip matches those models' DC-in port.

Will this charger still power my older ThinkPad Helix 3698-4UU alongside the Yoga 2 I use now?

Yes — the adapter's 20 V 2.25 A output and the listed part numbers ADLX45NCC3A, ADLX45NDC3A and 0B47030 cover both the Helix 3698 series and the Yoga 2 range.
