Convert Battery Lights To Ac Power

Connect the wires labeled with a minus sign to each other as well.

Convert battery lights to ac power.

8 aas wired in series would produce 12v which would still require a 15a draw. There is no way the terminals could withstand that much power. I use an old cell phone charger and an ac power plug from the reindeer. It is possible that the voltage of your switching module is too low to activate the leds string properly.

You can wire your existing light directly to the inverter. In this video i convert a battery powered led string of lights to run on 120 volts ac. But if an electrical device doesn t need to be portable all the time it would be nice to be able to power it with ac and not waste the batteries. I then forgot about the project until the material arrived.

All you need to do is to determine the voltage v and current mah of the device. Two cr2032 batteries should show a nomimal voltage of 6v or thereabouts. Use a wire cutter to strip about a half inch of rubber off of the tips of the battery s two wires. When it was time to complete the conversion i simply removed the 4 aa battery packs and connected the line from the string of led lights that needed power on the wreath to the output from the power pack.

A 180w device would be drawing 20 amps out of a 9v battery. Again that would cook your batteries. Bestek 500w power inverter dc 12v to 110v ac converter with alligator battery clamp 4 8a dual usb car charger etl listed 4 6 out of 5 stars 1 651 45 99 45. A 600 watt inverter should provide more than enough power for your light without quickly draining the battery.

Wrap electrical tape around any exposed wire. If you are tired of replacing batteries in your portable radio or in any other battery powered device using an ac power adapter is a good alternative. An ac power adapter converts 110 volts to a low direct current dc voltage. First off re connect the lights to the batteries and measure the voltage across the wires where the battery connections are.

So in this project i show you how to modify an old ac power adapter so that it can power your electronics instead of batteries. We use battery power to drive a lot of our electronics. Connect the wire in the lamp labeled with a plus sign to the battery wire labeled with a plus sign by twisting the two wires together. 180w is a lot of power.
