Replacement charger for Roborock Q7 L5 SPCDZ03RR

The ABLEGRID BLJ18WD200080P-U is a new non-OEM AC/DC adapter built to power the Roborock Q7 L5 SPCDZ03RR robot vacuum and mop combo. It delivers a fixed DC output of 20V 0.8A from a worldwide AC input of 100-240V at 50-60Hz. The unit carries CE, FCC and RoHS certifications and includes over-voltage and over-heat protection for safe daily charging.

Compact adapter with fixed output cable

The charger ships as a single unit with an integrated DC cord, so there are no detachable cables to misplace. Its plastic housing is designed for indoor use and the supplier advises keeping the adapter in a ventilated area away from skin-contact surfaces during extended charging sessions. No mounting hardware or additional connectors are included in the package.

Verify tip size and voltage before ordering

Buyers must confirm that the original Roborock power supply lists an identical DC output of 20V 0.8A and that the barrel tip dimensions match the robot charging port. The product notes explicitly require this check before purchase. This adapter is not suitable for devices that need a different voltage, current rating or connector polarity.
