The unit is nice however, the battery pack housing is very thin plastic and poorly designed. The cap actually broke and I had to replace it with a different battery housing.

Use your brain
You can by an adapter like this for $10 on Amazon. You can spend $75 if you want to, but I wouldn’t if I were you.

Power Supply for Touch On/Off switch
This power supply is for my Brizio touch on/off kitchen faucet. It works in conjunction with the actual 'switch' that I also purchased. The switch itself is suspect to work at best. That said, I suppose this power supply is doing the job it's designed to do.

Hi. I emailed an earlier question regarding my Delta 9197T faucet & compatibility with an EP102157. Can I omit the battery pack for the faucet or do I have to leave it plugged in? If not, when the batteries die, will the adapter still work?
Hi Laura,
Thank you for contacting Delta Faucet Company!
You can use the A/C adapter while leaving the batteries installed. The faucet will use the batteries as a backup if there are any issues with the adapter itself, or the plug-in.
We appreciate your inquiry. Please reach out directly if you have further questions!

How do you install the adapter, i have a touch faucet discontinued model version of the addison . I know you plug it in to electrical outlet but the other end where do you plug in
Hi NDS28,
Thank you for your question about the Delta Faucet EP102157.
A generation 3 solenoid, launched in 2015, has a hole to plug in the adapter. See a picture here:
