This adapter allows you to have 3 separate xt60 female plugs (power supply/battery end) from a single xt60 male. I started building these for my own purposes after looking online and realizing that other solutions involved brittle and exposed contacts on a circuit board or they used smaller gauge wire that simply couldn't handle the current flow I needed without huge inefficiency or even risk of fire. I use mine in my car alongside another adapter I offer, a male 12v accessory plug (cigarette lighter plug) to xt60 female, giving me a 12-volt power supply with 3 separate leads. I use this to run my power inverter, phone charger, and ISDT charger for my LIPO batteries for my drone. I can run all three simultaneously without issue or dealing with any more cigarette lighter plugs than are strictly necessary.

If you have a battery or power supply that has an XT90 you simply unplug down the middle of the adapter and you have a 3 way XT60 from a single XT90
