DC to AC Power?
I have a set of LED lights that are operated by a 3 AA battery pack. Issue is, battery life sucks and is too short, and I want to connect the lights to a wall outlet.
Light specs:
Power: 3 x AA battery
Supply voltage: 4.5V
Working Power: 3 W
Can I be steered in the right direction as to what to buy to achieve that? Amazon links welcome.

A 5 volt 1 amp wall-wort would do the job. https://www.amazon.com/BOLWEO-100-240V-Wireless-Co... is an example.

USE ANY SMARTPHONE CHARGER THAT PROVIDE 5V IS GOOD ENOUGH TO THE BATTERY PACK.
3 AA = 4.5V , BUT NO SUCH POWER SUPPLY CHEAP ENOUGH TO BUY IN MARKET.
OBTAIN 5V OUT FROM THOSE CHARGER USB SOCK FIRST PIN AND THE LAST PIN ( #4).

3W/4.5V= 650 mA. These sound like incandescent bulbs. Go to a surplus electronics house in your area and look for wall cube chargers of 4.5V @ more than 600ma. They should be cheap. They have boxes of them for $2-5. Make sure it works before you buy it. Take one of the lights with you to test it. They will usually help you.

You would need a transformer that converts 120v ac to 4.5v dc. Also you would need an adapter to connect the power supply. It might be cheaper to get rechargeable batteries and a battery charger.
