Kenmore DS4015 / DS4020 Stick Vacuum Charging Adapter

Kenmore built part 561051105 as the charging adapter matched to the DS4015 and DS4020 cordless stick vacuum battery pack, tuned to both voltage and connector, so this model-specific unit is the one worth using instead of a universal substitute.

Adapters rarely fail all at once. Watch for runtime that has quietly shortened compared with when the vacuum was new, a charge light that stays dark no matter how long it sits docked, or a machine that turns up empty despite an overnight connection. Before ordering a replacement, swap in a different wall outlet first, then check the connector barrel and the cable jacket right where it meets the charging brick, since that junction is where this style of adapter usually gives out. A pack that will not take a charge from a known-good adapter points at the battery instead, which is a separate part from this one.

• Part: charging adapter, part 561051105
• Fits: Kenmore DS4015 and DS4020 stick vacuum
• Function: supplies charging power matched to the DS4015/DS4020 battery pack
• Tip: test a second outlet before assuming the adapter itself has failed

A charge cycle that finishes unusually fast is worth investigating just as much as one that never finishes, since either pattern can point to a connector that is not making full contact rather than the battery itself. Confirm the model printed on your vacuum's body reads DS4015 or DS4020 before ordering, since Kenmore pairs its other stick vacuum lines with their own chargers and this listing covers these two models alone.
