Daisy chaining pedals means powering several pedals from one power supply output with a daisy chain cable, so the pedals on that chain share the output's current. Add up the current each pedal draws, keep the total under what the output supplies, and keep 9V pedals on 9V outputs.
Add up the current on each chain
Read the current each pedal draws from the pedal's own label or manual, then add the figures for the pedals that will share one output. The Hiree supply gives 9V 100mA on 6 outputs and 9V 300mA on 1 output, so a chain on a 100mA output stays under 100mA in total. The JOYO JP-02 gives 9V 100mA on 7 outputs and 9V 500mA on 1 output, and the Voodoo Lab X8 gives 500mA on each of its 8 outputs.
Match voltage and polarity before you plug in
Keep 9V pedals on 9V outputs, and use the 12V and 18V outputs only for pedals that take 12V and 18V. The JOYO JP-02 and the Tavsou supply both have 12V and 18V outputs, and both include a reversed polarity cable for pedals that need it. Check the pedal's own power label before you connect it, because the wrong voltage or polarity can damage a pedal.
Connect the chain from the supply to the pedals
Plug the daisy chain cable into one output on the power supply, then plug each pedal into the next connector on the cable. Run the cable along the pedals in the order they sit on the board. Leave the supply switched off while you plug the cable in, then switch it on.
Check for noise after you power up
Power the board up and listen for hum or buzz with the pedals on and the guitar silent. If noise appears, move a pedal to its own output, because pedals on a shared chain share the same current and ground. The Hiree supply has a built-in noise filter and the Tavsou supply has a noise reduction design, but a separate output separates the pedal from the shared chain.
Use the short-circuit protection as a safety net
If a pedal shorts, the supply's short-circuit protection cuts that output while the other outputs keep working. The Hiree, JOYO and Tavsou supplies each state separate short-circuit protection for their outputs, so a short in one channel will not stop the other channels. Check the pedal and the cable before you switch the supply back on.

Frequently asked questions
How many pedals can one output power?
As many as the output's current allows. Add the current each pedal draws and keep the total under the output figure, such as 100mA on the Hiree 100mA outputs or 500mA on the Voodoo Lab outputs.
Can I daisy chain pedals with different voltages?
No. Keep 9V pedals on 9V outputs and use the 12V and 18V outputs only for pedals that take those voltages. The JOYO and Tavsou supplies have 12V and 18V outputs for that purpose.
What happens if one pedal in the chain shorts?
The supply's short-circuit protection cuts that output while the other outputs keep working. The Hiree, JOYO and Tavsou supplies each state separate short-circuit protection for their outputs.
Do I need isolated outputs to daisy chain?
No. A daisy chain runs several pedals from one shared output, so the pedals on that chain are not isolated from each other. The supplies here have isolated outputs, which keeps each output separate from the next.
