This isn't an ordinary power supply. The Global Power Supply is a 15V, 4.34A power device crafted for the JustBoom Amp HAT on the Raspberry Pi. What's more, being a 'global' power supply, each order comes with plug adapters for the US, UK, EU, and Australia. It can handle high loads, so use it with care. Features include universal/full - range AC input, a fixed power supply output type, one output, an AC min input voltage of 90V, an AC max input voltage of 264V, a max output power of 65W, an output voltage of 15V for Output 1, an output current of 4.3A for Output 1, and a 2.1mm x 5.5mm x 12mm output connector.

Using this power supply is easy. First, connect it to your JustBoom Amp HAT on the Raspberry Pi using the 2.1mm x 5.5mm x 12mm output connector. Make sure to choose the right plug adapter according to your location (US, UK, EU, or Australia). Since it can handle high loads, don't overload it. Keep an eye on how much power your device is using. When not in use, unplug it to save energy. To maintain it, keep it in a dry and cool place. Avoid exposing it to water or extreme temperatures. If you notice any strange noises or smells, stop using it right away and check for problems.
