Yes, you can use a splitter. You'll need another adapter. Look on both of the adapters you have now and add their output amperages together. You'll need an adapter that can supply that amount of amperage.
The amperage will be stated on the adapters either on a sticker or embossed into the plastic case. It can be stated in various ways.
+5V, 1.25A means 1.25 amps at 5 volts.
+5V, 300mA means 300 milliamps at 5 volts. A milliamp is 1/1000 of an amp so 300mA would mean 0.300 amperes at 5 volts.
Taking those two as an example you would need an adapter with a minimum of 1.55 amps or 1550 milliamps. That's the minimum. Larger is fine but the new adapter must have at least the minimum of the combined amperages. So 2.0A or 2000 mA would be fine.
Continuing the above example, the splitter will have a maximum input rating that you should not exceed because you might melt it. So the splitter should be rated for at least 1.55 amps and, again, a higher rating is OK because you won't be running more power through it than that. If you tried to run 1.55 amps through a splitter that was only rated for 1.0 amps it would probably burn the splitter up and possibly start a fire.
