I’ve got a Sureflap cat flap operated by 4 AA batteries. It doesn’t work well on rechargeables, it seems to need 1.5v batteries.

I’m thinking to hardwire it with battery backup (like a Ups). I’m not very experienced in electronics, are there any off the shelf products I could use? I’m assuming the flap runs at 6v and that I can just attach two cables, one to plus, one to min.

If there are no off the shelve products, any recommendations for what I should buy?

    USB is gonna be 5V, which is lower than 6V, but then if it kinda works on 4x rechargeable, that’s probably 4.8V fully charged depending on battery chemistry.

    UPS and USB might work.
    No clue how much amps that motor pulls when activated, so it’s hard to give you a minimum for amps.

      I was thinking this usb powered battery replacement which has a 6v option. https://a.aliexpress.com/_m030556

      There’s no motor, just a click system to unlock / lock the flap. And easiest would be to plug it into a power bank which is also charged at the same time by 220v.
