Always use the original power adapter or charging cable that came with your pump. If you’ve purchased a newer model that didn’t include a power adapter, check your pump’s user manual and make sure the charging accessories match the recommended specifications.
For some Philips Avent electric breast pumps, a worn or older power adapter can affect the performance.
If you are using an older adapter version, contact Philips Customer Care to check if a free-of-charge replacement is available.
