myVolts 2957 20V 2A 40W AC adapter laptop battery

Replacement power for IdeaPad S10-2

This 20 V 2 A 40 W AC adapter replaces the original Liteon PA-1400-12 and PA-1400-11 units used with the Lenovo IdeaPad S10-2 netbook. It accepts worldwide 100-240 VAC input at 50 or 60 Hz and delivers a regulated 20 V DC output through a 5.5 mm outer by 2.5 mm inner barrel connector. Built-in over-voltage, over-current and short-circuit protection guards the netbook during charging. The unit is supplied new and tested for reliable operation.

Fits netbook charging directly

The adapter plugs straight into the netbook’s DC jack and a standard mains socket, so no extra cables or docking hardware are required. Its compact switching design keeps heat low while freeing the original power brick for travel or as a spare. The fixed 5.5 mm by 2.5 mm tip matches the IdeaPad S10-2 port without adapters, and the wide input range lets it work on mains supplies from 100 V to 240 V worldwide.

Suits owners of the IdeaPad S10-2 needing a new

Buyers with a different laptop model, a different barrel size, or a higher wattage requirement should look elsewhere. The adapter only provides 40 W at 20 V 2 A, so it cannot power larger laptops or devices that need more current. Users who need a battery pack rather than a mains charger, or who require a USB-C power delivery output, will not be served by this unit.
