Your power supply will need to be 13V2 to 13V8*, just put it in parallel with the battery and the load. Add a buck converter to get whatever lower voltages you need. You MUST put a fuse in one of the leads to the battery, as physically close to the battery as possible.
This toy just sits on the desk, so it’s a good candidate to modify to accept a DC power supply instead of batteries. This idea is not well suited to something like an R.C. Car, but in a pinch, you can use it on the remote control for your TV. Wall outlet power is generally alternating current, or ‘AC’.
Converting battery-operated devices to AC power can be a useful and cost-effective solution to keep your devices running without the need for constant battery replacements. To convert battery power to AC power, you need an inverter, which converts DC power from the battery to AC power that can be used to power your device.
Another option for connecting the power supply to the electrical device is to use a substitute or dummy battery. This is anything that takes the shape of the battery and fits in the battery housing, but is used to connect the power supply to the terminals of the battery connectors on the device.
Check the polarity of your batteries and power supply to ensure they match. There will be more on this in a later step. Before replacing batteries with a power supply, consider where the device or toy is used. Will it be sitting on a desk or near the bathtub? Would your kids put it in the bathtub?
To safely convert a device that runs on 4 D batteries to an AC electrical source, you need to use a power inverter that can handle the power requirements of the device. You can purchase a power inverter from an electronics store or online.
